Operation Analysis - Explanation by Stegemerten and Demmler in Maynard Handbook - Second Edition

They gave 10 primary points of analysis. I made them twelve  by writing Motion Analysis as a separate point and adding Jigs and Fixtures.

Purpose of Operation
Design of Part and Assembly
Tolerances and Inspection Requirements
Material Specification
Process of Manufacture
Equipment Analysis
Tools and Speed, Feed, and Depth of Cut
Jigs and Fixtures
Workplace Layout
Plant Layout
Material Flow
Motion Analysis

Many of the above points were covered in the book Operation Analysis by Maynard. But some points were convered in a different way and they are covered in this note.

Maynard and Stegemerten gave the following items for Operation Analysis in their book.

1. Purpose of operation.

2. Complete survey of all operations performed on part.

3. Inspection requirements.

4. Material.

5. Material handling.

6. Setup and tool equipment.

7. Common possibilities for job improvement.

8. Working conditions.

9. Method.

Material Specification

In a rapidly developing technology environment, the materials originally specified in the design may no longer be the most suitable. Designers may not review each and every part of a product on a continuous basis. Therefore, the industrial engineering analysts who has taken up the responsibility of improving the efficiency of the product and the process has to check the material specification periodically in his analyses.  The cost of materials keep changing also and processes that can be used on various materials keep changing. The industrial engineer has to keep familiar with developments in the field so that he may recognize materials that have become unsuitable and suggest more appropriate materials.

In the years. 1950s, the authors highlighted developments in plastics as something important for the IE to keep note of. They said, some plastics can acts as bearings without requiring lubrication.  Some plastics can resists acids and alkalis at much less expense than metals. Sheet steel may be coated with plastic. They also mention development of more easily machined metals.

They suggest the following questions.

1. Is a new material available to provide needed properties at lower cost.
Others are covered in the book

Process of Manufacture

Similar to the material specification, the manufacture process specified by the production engineering department originally may not the cost effective process now.  It becomes the responsibility of industrial engineering analyst to ensure that the best cost process is employed during his analysis project.

The authors gave example of epoxy adhesives. The wide availability of extruded sections of many materials, shell molding techniques etc. are also mentioned.  The appearance of less expensive numerically controlled machine tools, assembly devices (robotic hands), and assembly assits devices like part-orienting vibratory feeding devices are mentioned.  It is emphasized that the industrial engineer doing operation analysis work must keep abreast of developments in  the manufacturing area if he is going to produce results.

Equipment Analysis

When analyzing equipment, the industrial engineer must consider the machine capability. Routines for creating a machine-capability index are available and industrial engineer has to make sure that machine capability is calculated for various machines. This is required as time goes, machines lose the ability to produce to close tolerances. Hence, the machines are not used for high quality work after some time.

The questions suggested from machine capability or process capability angle.

1. Does the machine specified on the operation sheet have the capability to produce quality parts at the specified speed, feed, and depth of cut.

Tools and Speed, Feed, and Depth of Cut

The cutting tool manufacturers are doing research and development and coming out with tool bits that can give higher metal removal rates and also provide superior finished surface. Machine tools manufacturers are also coming out with machines having higher horsepower and rigidity.

The authors mentioned as examples, ceramic cutting tools, metal bonded diamond wheels, and new capabilities in tool grinding. Industrial engineers have new choices to increase productivity by employing higher cutting speeds, feeds and depths of cut.

Questions suggested.

1. Have the best possible speeds, feeds, and depth of cut been specified?

Plant Layout - Efficiency

Efficiency Measures of a Layout

Minimum Floor space: Efficient layout engineering can minimize floor space for a specified production output.

Minimum Materials Handling: Efficient layout results in minimum amount and cost of materials handling.

More Efficient Utilization of Machinery and Labor: An efficient layout eliminates general production delays, occasioned by congested aisles, cramped storage areas, crowding of machine layout, and improper materials handling devices, all of which lead to a slowing down of the production process as a whole and in general reduction in the output of goods from a given quantity of production machinery and labor.

Maximum flexibility of production facilities consistent with low cost of production: Production facilities and layout can be designed to attain flexibility and adaptability to meet changing economic and technological conditions.

Knowledge Required for Value Engineering Application and Practice

Value engineering involves application of value engineering approach and techniques to engineering knowledge in the case of products and processes in engineering industries.

Nature of Knowledge

The value analyst needs special tools and special knowledge to identify unnecessary costs and produce designs that avoid these unnecessary costs.

Difference in the knowledge between a specialist design engineer and value engineer.

A heat transfer specialist must possess accumulated knowledge in great volume pertaining to materials, heat conductivity, and practicable shapes and ideas for providing, preventing, or controlling the flow of heat.

In contrast, the special knowledge required for value engineering is extremely broad. It does not consist of knowledge in depth in any specific field of product design. Value engineer has to deal with and explore a multitude of technologies and product areas  to redesign the product assigned so that they give optimum performance and have optimum cost.

Value analyst or engineer requires information on materials, processes, functional products, sources of functional knowledge, approaches to function performances, practical ideas for economic function solutions. The best value alternative is the best combination of materials, processes and related ideas that combine to give a solution that secures the reliable performance of the desired  function or functions at the lowest cost.

A library of knowledge media like books, magazines, journals and information created and sent by various manufacturers, consultants and business organizations has to be maintained. In the current age computer based and web based knowledge sources also have to be maintained by the value engineering departments. But a library may still be insufficient. To achieve the value alternatives, apart from having a library of appropriate knowledge, the value engineer needs to develop channels for ready access to new information on materials, processes and suppliers of materials, processes and components. So a well organized references to sources of special skills needs to be maintained by value engineers.  Addresses of various consultants and faculty of academic institutions have to be maintained by the value engineering department.
In the case of various materials and processes, there must be enough knowledge available to make a preliminary evaluation of the suitability of the material, the product, the modified product, or the process to effectively accomplish the function involved, together with a reasonable amount of comparative information concerning costs.

Form of Knowledge

Handbooks, catalogues, charts, price lists, product and process descriptions, and tables etc. are forms of knowledge. L.D. Miles, the founder of value engineering recommends development of linking properties and costs also.

Reach or Depth of Knowledge

Value engineers are going to be less in number compared to performance engineers in any organization. Therefore value engineers are asked to work on variety of products and components related to various engineering disciplines. Therefore, the knowledge required for high-grade value work is extremely broad. A value engineer can't be expected to have in depth knowledge in any specific field.  But he needs to have broad knowledge that helps in recognizing specific materials and technologies from the multitude that have promise to provide optimum value for the product he is appraising and consulting.

Cost Reduction, Productivity Improvement and Industrial Engineering - Wind Energy Power Plants

Fabric Wind Turbine Blade Design Offers Clean Energy

Conventional wind turbine blade designs use fiberglass. A new approach using architectural fabrics could change the way blades are designed, manufactured and installed.

GE researchers, in partnership with Virginia Polytechnic Institute and State University (Virginia Tech), and the National Renewable Energy Laboratory (NREL) are exploring a new wind turbine blade design and manufacturing approach using architectural fabrics that could be wrapped around a metal space frame resembling a fishbone.

The new wind turbine blade design being explored could reduce blade costs 25% to 40%. This degree of cost reduction could make wind energy as economical as fossil fuels without government subsidies.

It is estimated that to achieve the national goal of 20% wind power in the U.S., wind blades would need to grow in length by 50%—a figure that would be virtually impossible to realize given the size constraints imposed by current technology. Lighter fabric blades could make this goal attainable.

Market Research - Product Testing for Redesigned for Products with Lower Cost

Cost reduction test designs
When beginning a major cost-reduction initiative, decisions must be made that can have a profound effect on the sensitivity of the design, including:

Blind or branded - Should the product shown to respondents have any identifying labels or logos?
Test environment - What is the physical setting in which respondents will evaluate the product?
User qualifications - What type of respondent do you want evaluating your new product?
Sensitivity of design - How sensitive do you want the design to be to detecting changes in respondent opinion?
Decision rule - What amount of difference in ratings between the original and new product do you consider acceptable?

More details are to be ascertained from different sources on this topic. The topic is of importance to industrial engineers as their efficiency redesigns have to pass these consumer product tests.

Value analysis as a decision support tool in cruise ship design
International Journal of Production Research
Volume 48, Issue 23, 2010
Pietro Romanoa*, Marco Formentinia, Camillo Banderaa & Marco Tomasellaa
pages 6939-6958
Because of time constraints, as a matter of fact, design decisions are made fast and in a reactive way, according to the particular case, without considering decisions made in the past and without using specific decision support tools. The final choice is often left to a single designer's experience, whose selection criteria are unknown and not formalised. As a consequence there is no shared knowledge justifying the reason why a design solution has been chosen and whether it is the best one. We developed and implemented in Fincantieri S.p.A. – a leading company in the cruise ship industry – an original decision support tool, based on value analysis, designers can use to document and formalise their choices. Value analysis is a well known structured method to increase product value and/or cut costs, thus supporting the selection of the most valuable solution by means of objective parameters. We demonstrate that the proposed tool can also facilitate reuse of the available knowledge base on decisional criteria, increase interactions between people (design staff, buyers, shipyard personnel, etc.) involved in different stages of different value analysis projects, and reduce decision time.

India has  labour cost advantage. . The labour cost per worker in India is
estimated at $1,192 per year, against $10,743 and $21,317 per worker in 2007 in South Korea and Singapore. . Labour cost is a key factor in shipbuilding nations as it accounts for more than 10% of the total costs. China also has considerably lower labor costs as compared  to competing countries. (Around 50% of Korea and Japan).

A shipyard typically requires a working capital of around 25-35% of the cost of the  ship during the entire construction period.

Indian yards lack the capability to build large and modern ships. Presently, the Cochin shipyard is the
only one that has the capability to build large and modern ships. Hence shipbuilding in India lacks
infrastructure support which reduces the capacity of production.

Brain storming particles for productivity improvement - Blog Posts and Emails by Industrial Engineers

Brain storming particles for productivity improvement.

I suggest that all industrial engineering participating in productivity improvement contribute at least one productivity initiative of theirs every year through a blog post or email in a group. The blog post can be in their own blog, on a blog of their company or it can be submitted to blogs of their institute or professional associations. That way the community will have multiple examples of productivity improvement in the entire global economy and some of these examples act as brainstorming particles that excite others to think and implement productivity measures in their organizations. By sharing only one idea every year, every industrial engineer engaging in productivity improvement can energize the entire profession.

Industrial Engineering Statistics - Application of Statistics in Industrial Engineering Practice

Industrial engineering is productivity improvement. Industrial engineering is cost reduction. Industrial engineering efficiency improvement.

Industrial engineering is improving the productivity of every resource used in production using engineering processes. It can also be said that is improving the productivity of every process or operation of the process.

What is the role of the statistics subject in industrial engineering?

Have industrial engineers spent time on this question? Or have they taken some methods or tools developed by statisticians and simply added to their toolkit to apply them as they have the potential increase the productivity of processes.

Statistical Process Control and Statistics Quality Control were developed by statisticians and inspection and testing department people. Industrial engineers promoted them as they increased productivity by reducing time spent by people on these activities. When time spent by people goes down, time spent by equipment and tools also go down. Hence many times productivity improvement of one resource can mean productivity improvement of other resources also.

Introduction to Engineering Statistics and Lean Sigma: Statistical Quality Control and Design of Experiments and Systems
Theodore T. Allen
Springer Science & Business Media, Apr 23, 2010 - 600 pages
Lean production, has long been regarded as critical to business success in many industries. Over the last ten years, instruction in six sigma has been increasingly linked with learning about the elements of lean production. Introduction to Engineering Statistics and Lean Sigma builds on the success of its first edition (Introduction to Engineering Statistics and Six Sigma) to reflect the growing importance of the 'lean sigma' hybrid. As well as providing detailed definitions and case studies of all six sigma methods, Introduction to Engineering Statistics and Lean Sigma forms one of few sources on the relationship between operations research techniques and lean sigma. Readers will be given the information necessary to determine which sigma methods to apply in which situation, and to predict why and when a particular method may not be effective. Methods covered include: • control charts and advanced control charts, • failure mode and effects analysis, • Taguchi methods, • gauge R&R, and • genetic algorithms. The second edition also greatly expands the discussion of Design For Six Sigma (DFSS), which is critical for many organizations that seek to deliver desirable products that work first time. It incorporates recently emerging formulations of DFSS from industry leaders and offers more introductory material on the design of experiments, and on two level and full factorial experiments, to help improve student intuition-building and retention. The emphasis on lean production, combined with recent methods relating to Design for Six Sigma (DFSS), makes Introduction to Engineering Statistics and Lean Sigma a practical, up-to-date resource for advanced students, educators, and practitioners.

Modern Engineering Statistics
Thomas P. Ryan
John Wiley & Sons, Jun 22, 2007 - 736 pages
An introductory perspective on statistical applications in the field of engineering
"Modern Engineering Statistics" presents state-of-the-art statistical methodology germane to engineering applications. With a nice blend of methodology and applications, this book provides and carefully explains the concepts necessary for students to fully grasp and appreciate contemporary statistical techniques in the context of engineering.

With almost thirty years of teaching experience, many of which were spent teaching engineering statistics courses, the author has successfully developed a book that displays modern statistical techniques and provides effective tools for student use. This book features:

Examples demonstrating the use of statistical thinking and methodology for practicing engineers

A large number of chapter exercises that provide the opportunity for readers to solve engineering-related problems, often using real data sets

Clear illustrations of the relationship between hypothesis tests and confidence intervals

Extensive use of Minitab and JMP to illustrate statistical analyses

The book is written in an engaging style that interconnects and builds on discussions, examples, and methods as readers progress from chapter to chapter. The assumptions on which the methodology is based are stated and tested in applications. Each chapter concludes with a summary highlighting the key points that are needed in order to advance in the text, as well as a list of references for further reading. Certain chapters that contain more than a few methods also provide end-of-chapter guidelines on the proper selection and use of those methods. Bridging the gap between statistics education and real-world applications, Modern Engineering Statistics is ideal for either a one- or two-semester course in engineering statistics.

Kim H. Pries, Jon M. Quigley
CRC Press, Mar 21, 2013 - 365 pages

A company with effective cost reduction activities in place will be better positioned to adapt to shifting economic conditions. In fact, it can make the difference between organizations that thrive and those that simply survive during times of economic uncertainty. Reducing Process Costs with Lean, Six Sigma, and Value Engineering Techniques covers the methods and techniques currently available for lowering the costs of products, processes, and services.

Describing why cost reductions can be just as powerful as revenue increases, the book arms readers with the understanding required to select the best solution for their company’s culture and capabilities. It emphasizes home-grown techniques that do not require the implementation of any new methodologies—making it easy to apply them in any organization.

The authors explain how to reduce costs through traditional Lean methods and Lean Six Sigma. They also present Six Sigma cost savings techniques from Manufacturing Six Sigma, Services Six Sigma, and Design for Six Sigma. The book also presents optimization techniques from operations research methods, design experiment, and engineering process control.

Helping you determine what your organization’s value proposition is, the text explains how to improve on the existing proposition and suggests a range of tools to help you achieve this goal. The tools and techniques presented vary in complexity and capability and most chapters include a rubric at the start to help readers determine the levels of competence required to perform the tasks outlined in that chapter.

The Role The of Industrial Engineer in Product Design - Points Made by William McAlee and Harold Lawson

The article was published in the 2nd Edition of Maynard Industrial Engineering Handbook as chapter 10.5

Industrial engineering has a role in both the design for making and design for selling.

Industrial engineer's knowledge of methods improvement, motion economy and motion study, work measurement using stop watch as well as predetermined motion times enable him to redesign the product designs to make the less costly to manufacture and also make them less costly to use by the user.

Design for Making

The industrial engineer is a key person reviewing the design. He makes an analysis of design to determine if it is possible to manufacture at an economical cost. Based on the analysis, he finds ways to reduce costs through suggested design modifications prior to final design approval,

Industrial engineer is also an engineer and hence has knowledge of design process and method. He redesigns the production process also to obtain lower cost of production.  He does this without affectinig the quality, appeal, salability, or any other aspect of the product desired by the customer and explicitly designed in by the product design team. An industrial engineer does this work by his knowledge of equipment, processes, tools, wages and the like.

The typical examples of suggestions by industrial engineers for redesign were given by the authors as:

1. Relocation of holes, appendages, fasteners, and the like for easier access in processing or assembly.
2. Modification of design to use existing tools, jigs, fixtures or equipment.  (especially if a new equipment is suggested that will have low utlization)
3. Addition of tapers, rounded edges, and symmetry to parts to simplify positioning required for assembly.
4. Specification of easier to use fasteners (Shigeo Shingo came out with various ideas on fasteners to reduce set up times of machines)
5. Use of free machining stock or use of materials having higher machinability.

Design for Manufacturing and Assembly: Concepts, architectures and implementation

O. Molloy, E.A. Warman, S. Tilley
Springer Science & Business Media, Dec 6, 2012 - 205 pages

In order to compete in the current commercial environment companies must produce greater product variety, at lower cost, all within a reduced product life cycle. To achieve this, a concurrent engineering philosophy is often adopted. In many cases the main realization of this is Design for Manufacture and Assembly (DFM/A). There is a need for in-depth study of the architectures for DFM/A systems in order that the latest software and knowledge-based techniques may be used to deliver the DFM/A systems of tomorrow. This architecture must be based upon complete understanding of the issues involved in integrating the design and manufacturing domains. This book provides a comprehensive view of the capabilities of advanced DFM/A systems based on a common architecture.

Achieve Lasting Process Improvement
Bennet Lientz, Kathryn Rea
Routledge, 10-Jun-2002 - Business & Economics - 281 pages
Methods of improving business processes are developed on an ongoing basis, but few are successful. Common problems encountered include the failure of processes to meet expectations and the inability to sustain or replicate these business processes. Involvement of personnel at grassroots level, as well as at management level, is essential in implementing effective process improvement methods.

The authors present a step-by-step approach to the issue of effective process improvement, offering more than 200 tips and guidelines as well as addressing specific common problems and issues. The strategy presented is to take a broad and intuitive, but learned view of process improvement methods, and the tactics expounded are based on guidelines, common faults, and lessons learned. The authors disparage process improvement operations that depend on jargon and the support of just upper management, and promote grassroots involvement and self-sustaining measurement, making this an essential guide for all with involvement in process improvement

Purpose, Methods and Application Areas of Industrial Engineering

What is the purpose of industrial engineering? How is it different from the purpose of engineering of various disciplines and management of various areas? What are industrial engineering methods and techniques? In what areas IE is applied? These questions were answered by different people at various places.

My answer is purpose of IE is redesign of engineering products, processes and engineering goods and services production systems for reducing cost of products and processes. Engineering is concerned with original technical design. Managers are concerned with customer requirements, recruiting and directing engineers to create products and production systems that satisfy customers and interacting with customers to deliver products and collect payments.

Industrial Engineers are concerned with continuous improvement of product designs, production processes and production systems to increase productivity, eliminate waste and reduce costs.

The IE methods can be categorised into 1. Product design efficiency improvement. 2. Methods efficiency improvement 3. IE optimization 4. IE statistics . 5 IE Economics 6. Human effort engineering 7. Work measurment, cost measurement, and productivity measurement 8. Management of IE studies, projects and departments.

I feel IE curriculums must have these components and number of subjects that explain each area so that an IE graduate can deliver these services in an integrated fashion in an engineering organization.

In an engineering organization, the primary areas for attention of industrial engineers are technical processes.  The experience gained by industrial engineers in improving technical areas can be used to improve business processes and management processes. Every individual Industrial engineer, must first be inducted into IE profession through study and improvement of technical areas of the organization.

From Chapter 1.5 Management's Use of Industrial Engineering by J. Keith Louden, Vice President and Fellow, American Management Association, President's Professional Association, New York

Industrial Engineering Handbook, H.B. Maynard, Second Edition

Objective of Industrial Engineering

The end result of the industrial engineering function is profit improvement. The line manager of a department is actually responsible for profit improvement in his department. He is aided materially by the industrial engineering function.

Manufacturing Functions Use of Industrial Engineering

Industrial engineering was born in the shop.

The manufacturing executive look to IE department to establish standards of measurement for every phase of manufacturing operations. He expected aid in simplifying work regardless of its nature or where it is performed. He also wants IE to define each job function and to evaluate each in comparison with others and determine relative worth. To establish controls and measuring sticks, so that manufacturing activities are better managed.

Role of Industrial Engineer in Today's Engineering Organizations

William J. Zehe of Middough Inc. explained industrial engineering in the modern time. Some of the activities he described as extremely relevant to explain the role of industrial engineering very clearly.

As production technology evolves, markets and demand expand or contract,  cost control
continues to drive the competitive advantage,

The industrial engineer can evaluate manufacturing system designs, thereby avoiding costly production bottlenecks while at the same time minimizing "over design" often employed as a contingency in variable manufacturing situations.

Typically the role of the Industrial Engineer is to constantly strive to make things work better,
whether it involves processes, products, or systems. Industrial  engineer is the bridge between management goals and the company’s operational performance.

Typical Industrial Engineer’s activities:

• Productivity and methods improvement
• Manufacturing and distribution
• Integration of supply chain
• Quality measurement and improvement
• Ergonomics & human factors engineering


A key task in any manufacturing facility is to continuously reduce cost. Thus an important role
of the Industrial Engineer is continuing to fine tune a well oiled machine including
identification of improvements and manage implementation strategies. These tasks include:

Defining key production metrics
Define goals, measurement tools, data analysis strategies
Lead team to perform root cause analysis to improve weak performers
Develop capacity measurements
capital budgets and justifications
Continuous improvement
              Coordinate change programs
              Establish priorities, schedules and goals
              Provide on-going leadership to assure successful implementation


Managing the cost of getting a product to the market is paramount in being successful. Many
elements are involved in this process and must start at the design phase of the product.
Typically the Industrial Engineer is involved as the product matures and transforms from
the design phase into trial production and eventually to full scale production. The activities
associated with this include:

• Design for manufacturing and assembly reviews

o Identify any changes that would reduce the manufacturing cost without
compromising the design
• Methods and Procedures Analysis and Review
o Evaluate equipment capacities
• Develop product specific routings, special instructions, manufacturing standards
• Develop staffing requirements,
• Facilitate and lead continuous improvement teams
• Provide simulation of process flow

facilities rely on a number of suppliers to provide goods and/or
services for the products they produce. Integrating the suppliers into the manufacturing
more important in an effort to control costs in today’s
competitive environment. The Industrial Engineer is often the link between
manufacturing facility and the suppliers. The tasks typically include:

Controlling costs includes the development of processes and procedures for the manuf
of a product that incorporate the health and welfare of the employee tasked to provide the
goods and services. Most of the activities are associated with how the material is handled
during the production sequence, what tooling is utilized and what is the body position requ
of the employee during the production sequence. The Industrial Engineer will:
• Interface with applicable stake holders to insure ergonomics is incorporated into all
aspects of the product from development, design, manufacturing, material handling,
Working as team leader or integral team member
develop long range planning models for the facility, including
and manpower requirements. Th
• A rolling five year strategic plan updated annually
• Capacity planning and
• Implementation costs including capital justifications
• Preliminary financial impacts and ROI

sub tier to continuous improvement; an integral part of assuring
meets expectations. In this case the Industrial Engineer works in concert
company’s quality department or in some cases becomes the lead investigator to
quickly resolve issues affecting the product quality, either in house or issues with supplier
. These activities may include:
Root cause identification and implementation of corrective action including:
Process revisions
Material flow or handling revisions
Applicable training
Interface with design, production, and suppliers on quality related issues
Development of quality measurement tools, techniques and analysis

Cost Based Assembly Line Optimization

Preliminary Draft - To be rewritten.

Equipment Costs:  Equipment costs concern purchasing as well as operating and maintenance costs for machinery, tools and corresponding supplies. There exist various processing and equipment
alternatives and therefore the choice of equipment and the task assignment to stations becomes interrelated decisions.

Graves and Lamar [1983] were among the first to consider a line balancing problem combined with equipment choice by considering non-identical workstations.

Bukchin and Tzur [2000]  optimized equipment cost respectively, for simple  lines.

Nicosia et al. [2002] also studied this problem and proposed a dynamic programming algorithm addressing resource assignments,

approximate solution approaches were used to produce solutions for FMS [Chen and Ho, 2005]. Following a multiobjective approach and making use of Pareto dominance relationships, Chen and Ho [2005] addressed four criteria: total flow time, machine workload unbalance, greatest
machine workload and total tool cost.

Bukchin and Rabinowitch [2006] relaxed the assumption that a common task of different models is assigned to a single station. They also attempted the mixed model line problem. However, task
duplications are penalized through duplication costs in the objective function. For solution, a branch and bound solution algorithm was developed.

Pekin and Azizoglu [2008] generalized the work of Bukchin and Tzur [2000] by minimizing total equipment cost and total number of workstations simultaneously. They generated the set of non-dominated solutions.

Similarly, addressing resource assignments, Corominas et al. [2011] formulated a general
model that minimizes total cost, which includes fixed station costs and unit cost of different resource types.

Barutcuoglu and Azizoglu [2011] investigated the same problem, however they fixed the number of stations and added the assumption that operation time and equipment cost are correlated so that the cheaper equipment never produces shorter operation time.

Kazemi et al. [2011] extended the model of Bukchin and Rabinowitch [2006] for U-type lines. The authors used genetic algorithms to solve the problem.

Transfer Line Balancing

Another optimization area that focuses on equipment selection is transfer line balancing [Belmokhtar et al., 2006, Dolgui et al., 2006c,a, 2012, Battaia and Dolgui, 2012, Borisovsky et al., 2012, Delorme
et al., 2012]. In these systems, stations can be equipped with changeable units such as spindle heads. These units that operate parallel at a station are called blocks. The problem is to figure out the optimum number of stations and block assignments so that total line investment cost is

When assembly line balancing and equipment selection problems are simultaneously treated, the resulting more complex problem is called assembly system design problem (ASDP). It
associates the equipment selection for task requirements and task assignment to the stations. In this concurrent decision, a cost-based objective such as the fixed cost of installing the equipment in the stations and the variable cost of operations depending on the station is optimized.

[Pinnoi and Wilhelm, 1997b,a, Wilhelm, 1999, Pinnoi and
Wilhelm, 1998, Gadidov and Wilhelm, 2000, Pinnoi and
Wilhelm, 2000, Wilhelm and Gadidov, 2004].

Ozdemir and Ayag [2011] have examined a multi-criteria ASDP. They integrated the branch and bound and analytic hierarchy process (AHP) so that first, the branch and bound generates line design candidates, then, these alternatives are assessed with AHP method to choose the optimal candidate.

Reconfigurable Manufacturing Systems (RMSs)

One of the main challenges of industry is to respond to the rapid changing demands of the customers. Accordingly, reconfigurable manufacturing systems (RMSs), which give emphasis to modularity and customization of machines and processes, has been widely employed recently.

RMSs facilitate manufacturing systems that can change configuration such as altering the layout or adding machines cost effectively [Dolgui and Proth, 2010].

Integer programming models minimizing equipment and installation cost and approximate solution methods are generally used [Youssef and ElMaraghy, 2007, Essafi et al., 2010, Dou et al., 2011].

A heuristic approach based on a Greedy Randomized Adaptive Search Procedure (GRASP) has also been proposed for this problem [Essafi et al., 2012].

An other case has been studied by Hamta et al. [2011, 2013], who modeled flexible operation times in the sense that with additional costs task times can be reduced up to a limit. A linear time/cost relationship was assumed.
