What is the role of industrial engineering in systems engineering? Can you give some important issues.


Answer by Leon McGinnis

Professor Emeritus at Georgia Tech, Industrial and Systems Engneering

--

Perhaps a better question is: What is the role of systems engineering in industrial engineering? Industrial engineers often are involved in the design or improvement of large systems such as distribution centers, factories, supply chains, health care systems, etc. These all typically involve multiple disciplines (mechanical, electrical, civil engineering; architecture; controls; robotics; etc), exhibit multiple interacting subsystems, have multiple stakeholders often with conflicting objectives, have lengthy design/build cycles, have long lives, and are very expensive. In other words, they are large, expensive, long-lived artifacts that must operate effectively under changing conditions. An excellent target for adding systems engineering methods and tools to the IE's toolbox.

Systems Engineering in Industrial and Systems Engineering (ISE)

SYSTEMS ENGINEERING PRINCIPLES AND PRACTICE

SECOND EDITION

Alexander Kossiakoff

William N. Sweet

Samuel J. Seymour

Steven M. Biemer



The following characteristics are commonly found in successful systems engineers. 

They 

 1. enjoy learning new things and solving problems, 

 2. like challenges, 

 3. are skeptical of unproven assertions, 

 4. are open - minded to new ideas, 

 5. have a solid background in science and engineering, 

 6. have demonstrated technical achievement in a specialty area, 

 7. are knowledgeable in several engineering areas, 

 8. pick up new ideas and information quickly, and 

 9. have good interpersonal and communication skills.



Industrial engineering is concerned with design, installation and improvement of systems having machines, men, material, energy and information to produce goods and service. Its special focus is on specifying, evaluating and improving results expected from these systems.

Therefore industrial engineering focuses on results expected from engineering systems at the design stage, installation stage and operation stage.

Both industrial engineering and system engineering need knowledge, achievement and expertise in multiple engineering areas.



Ch. 2. SYSTEMS ENGINEERING LANDSCAPE


 The essence of the systems engineering viewpoint is  making the central objective the system as a whole and the success of its mission. This, in turn, means the subordination of individual goals and attributes in favor of those of the overall system. The systems engineer is always the advocate of the total system in any contest with a subordinate objective.


A Balanced System 

 One of the dictionary definitions of the word “ balance ” that is especially appropriate to system design is “ a harmonious or satisfying arrangement or proportion of parts or elements, as in a design or a composition. ” An essential function of systems engineering is to bring about a balance among the various components of the system, which, it was noted earlier, are designed by engineering specialists, each with expertise on optimizing the characteristics of a particular component.


 A broader and robust perspective to systems approaches to solve very extensive complex engineering problems by integrating engineering, management, and social science approaches using advanced modeling methodologies is termed “ engineering systems. ” The intent is to tackle some of society ’ s grandest challenges with significant global impact by investigating ways in which engineering systems behave and interact with one another including social, economic, and environmental factors. This approach encompasses engineering, social science, and management processes without the implied rigidity of systems engineering. Hence, applications to critical infrastructure, health care, energy, environment, information security, and other global issues are likely areas of attention. 

This "engineering systems" is appropriate for systems with which industrial engineering is concerned. These systems include customers, suppliers and operators.



Systems Engineering Viewpoint 

 The systems engineering viewpoint is focused on producing a successful system that meets requirements and development objectives, is successful in its operation in the field, and achieves its desired operating life. In order to achieve this definition of success, the systems engineer must balance superior performance with affordability and schedule constraints. In fact, many aspects of systems engineering involve achieving a balance among conflicting objectives. For example, the systems engineering typically must apply new technology to the development of a new system while managing the inherent risks that new technology poses. 

 Throughout the development period, the systems engineer focuses his or her perspective on the total system, making decisions based on the impacts and capabilities of the system as a whole. Often, this is accomplished by bridging multiple disciplines and components to ensure a total solution. Specialized design is one dimensional in that it has great technical depth, but little technical breadth and little management expertise. Planning and control is two dimensional: it has great management expertise, but moderate technical breadth and small technical depth. But systems engineering is three dimensional: it has great technical breadth, as well as moderate technical depth and management expertise.

Systems Efficiency Engineering - A Focus Area of Industrial Engineeering


Blog Post Publication Date: 6.6.2013
Published still earlier as Knol number 869.


Systems efficiency engineering is one of the focus areas of industrial engineering according to me. The other area of focus is human effort engineering.

Functional design of a system and efficiency design of system are different activities. In mechanical engineering, design of a mechanism and design of machine elements to implement the mechanism are different activities. A machine requires first a mechanism design and then machine element design. Then somebody has to do a process design to manufacture each element and then assemble them into an assembly. Similarly functional design of a system and efficiency design of a system are two different activities under division of labor.

Is efficiency engineering a new word that I am coining for the first time? No. Efficiency engineering was used in the past by many authors and thinkers. The new thing that I want to emphasize is the difference between functional engineering or design and efficiency engineering or design. Industrial engineering has focused on efficiency of systems.

Scientific Management, as it was called, involved the application of the scientific method to understand business problems and improve workplace efficiency. Previously, most managers lacked quantitative data and information and thus often relied on hunches and educated guessed to manage their business. By the early 1900’s, Scientific Management evolved into “efficiency engineering” with its main focus being optimization of a single process (i.e. point optimization), and then later “industrial engineering” whose focus expanded to system optimization – i.e. improvement of interrelated processes.

Concept and Principles of System Efficiency Engineering

Industrial Engineering is System Efficiency Engineering.

Its Main Components are Machine Effort and Human Effort Efficiency Engineering.

Synonyms: #Productivity #CostReduction  #Efficiency  #WasteElimination

Systems have many sub-systems or components. A manufacturing system has manufacturing  and administrative sub-systems. The manufacturing system can have many factories. In each factory multiple products are produced and each product has a process of manufacturing and products may use common facilities. The processes have operations. In each operation machines and men work on materials.  Machines and men have various elements that have an impact on the effectiveness and efficiency.

Effectiveness of a business system is production of goods and services at prices and quality that satisfy the customers. Then only there will be business revenues through sales. Efficiency is related to the cost incurred in producing goods of right quality. Efficiency is more if cost of production is lesser and lesser without affecting the quality of parameters of importance of the customers. Product redesign and process redesign are attempted by companies to change material specifications, dimensions and ways of processing in a way that maintains the expected performance of the product. For this purpose, the new inventions and innovations are utilized apart from the ideas that come to mind due to learning effect and creative outbursts of all employees.

We can say may areas in industrial engineering, like product IE, process IE, facilities IE, operation IE, Engineering Element level IE, Process machine effort IE, Process human effort IE etc., taking care of various sub-systems or components of engineering systems or production systems. 

Effectiveness First and Efficiency Next.  Organizations have to be effective and efficient simultaneously. Processes have to be effective and efficient simultaneously. Operations have to be effective and efficient simultaneously. - Narayana Rao

Difference between Performance Engineering (Effectiveness Engineering) and Value Engineering (Efficiency Engineering)


L.D. Miles brought out this difference more clearly. Designing a product to given specification and getting a prototype made that is acceptable to customers is a demanding task. This is performance engineering. Redesigning this working prototype to manufacture it at the lowest cost without sacrificing any feature that the customer desires is value engineering (efficiency engineering). These two activities can be better performed as two separate activities and this will give better results. As Adam Smith noted, division of labor improves productivity. Industrial engineering is efficiency engineering while traditional engineering disciplines are effective engineering disciplines.


Adam Smith


In particular economic growth, to be interpreted as growth in per capita income, has to be reconducted to two factors: labor productivity and the proportion of productive to unproductive workers. Labor productivity, which is considered the most important of the two, essentially depends on the division of labor which: a) improves the dexterity of the worker; b) allows the worker to save the time necessary to switch among different activities; c) puts the worker in the condition of inventing machines to facilitate his job.

Principles of Efficiency - Harrington Emerson


Harrington Emerson contributed to the systems efficiency focus of industrial engineering. His book Twelve Principles of Efficiency was classic.

He discussed efficiency design of organization through 12 principles

1. Clearly defined ideals.
2. Common sense
3. Competent counsel
4. Discipline
5. The fair deal
6. Reliable, immediate and adequate records
7. Despatching
8. Standards and schedules
9. Standardized conditions
10. Standardized operations
11. Written standard-practice instructions
12. Efficiency-reward

Harrington Emerson - A Pioneer Industrial Engineer - Principles of Efficiency

Babbage Principle


In "On the Economy of Machine and Manufacture", Babbage described what is now called the Babbage principle, which identified advantages with division of labour. Babbage noted that highly skilled—and thus generally highly paid—workers spend parts of their job performing tasks that are "below" their skill level. If the labour process can be divided among several workers, it is possible to assign only high-skill tasks to high-skill and -cost workers and leave other working tasks to less-skilled and paid workers, thereby cutting labour costs. (page 137-138).

Role of Efficiency

Producers exist to convert inputs into desired goods and services in an efficient manner. Given that output prices and factor prices are determined in competitive markets, efficiency means exploiting existing production technology to the greatest extent possible. Profits earned by the entrepreneur represent the reward for taking risks (facing an uncertain demand for the output) and achieving efficiency in production (relative to competing producers) -- profits that are least equal to what the entrepreneur could earn by working for someone else.

Sentences from Harold Koontz and Cyril O'Donnell,  Principles of Management, Fourth Edition, McGraw-Hill, New York, 1968, on Efficiency.


p. 742

The goal of all managers in all enterprises must be the effective accomplishment of purpose (whatever it is) with the most efficient utilization of resources-human and material-at their disposal.

The purpose of business is to satisfy the economic wants of people, and, since resources are scarce, their efficient use is a moral requirement.

p. 744
It is not enough to produce economic goods; the first duty of business is to produce them efficiently.

Since businessmen obtain control scarce resources by the purchase or lease of land and capital and hire human services, they have a moral responsibility for using them efficiently in the production

It is the business of the state to make sure through legislation and regulation that the private economy does not fail in its function to efficiently utilize resources to maximize the satisfaction of consumer wants for economic goods and services.


Principle of Suboptimization



PRINCIPLE OF SUBOPTIMIZATION

Optimizing each subsystem independently will not in general lead to a system optimum, or more strongly, improvement of a particular subsystem may actually worsen the overall system. The principle of suboptimization provides the basis for a link between organizational structure and the policies adopted.

The well-being of an element is dependent on the well-being of the system of which it is a part. It is sometimes necessary for an element to limit its goals and actions in order to preserve the well-being of the system. In acting to achieve its goals one element may come to constrain the actions of another element to the point of serious injury to the other element.

Marginal Productivity Theory


Resources are employed till their marginal productivities are equal for the addition unit of payment for optimizing the resources employed in the production.

System Efficiency Engineering - Methods, Subjects, Techniques, and Tools

 Effectiveness First and Efficiency Next.  Organizations have to be effective and efficient simultaneously. Processes have to be effective and efficient simultaneously. Operations have to be effective and efficient simultaneously. - Narayana Rao


System Efficiency Engineering - Methods, Subjects, Techniques, and Tools


System efficiency engineering is one of the components of industrial engineering. Actually, the purpose of industrial engineering is efficiency improvement. Productivity is part of efficiency. Productivity is defined as output divided by input. It is calculated for a period like a year or month. The inputs can be individual resources or combinations of inputs. Efficiency also considers the state of resources after their use in processes. If the operators participating in a process are unhappy after the activity, it is part of inefficiency. Industrial engineers have to redesign the processes, not only to increase output in a single period, but also to maintain the resources in good sustainable condition to do work in the future.

Efficiency engineering is a term used by many to describe scientific management and industrial engineering. 

Judith Merkle[1] used the term "A Permanent Revolution in Efficiency Engineering" as subheading in his book Management and ideology: the legacy of the international scientific management movement, published by  University of California Press in 1980.

The following methods or techniques are available in industrial engineering to support system efficiency. Some of them are taught as full subjects in industrial engineering curriculums.

1. Engineering Economics or Engineering Economy.
2. Layout efficiency studies - Study of distance moved by materials and operators
3. Method Study includes process analysis or study and operation analysis or study.
4. Operations Research
5. Organization and Methods or Office Systems Study
6. Planning and Control Systems Improvement
7. Statistical Inventory Control

The Carnegie Mellon Process Systems Engineering (PSE) group represents one of the largest university research efforts for process systems engineering in the United States. Over the past four decades, the PSE group (Professors Biegler, Gounaris, Grossmann, Sahinidis, and Ydstie) has changed the global landscape of process systems engineering, providing intellectual leadership in complex decision-making issues faced by process industries, such as the petrochemical and emerging energy technology industries. Our underlying approach is based on developing and advancing systematic modeling and solution methods for multi-scale process systems engineering, covering the full spectrum from the molecular to the enterprise level.

Facets of Systems Science

Springer Science & Business Media, 21-Nov-2013 - Business & Economics - 664 pages

This book has a rather strange history. It began in Spring 1989, thirteen years after our Systems Science Department at SUNY -Binghamton was established, when I was asked by a group of students in our doctoral program to have a meeting with them. The spokesman of the group, Cliff Joslyn, opened our meeting by stating its purpose. I can closely paraphrase what he said: "We called this meeting to discuss with you, as Chairman of the Department, a fundamental problem with our systems science curriculum. In general, we consider it a good curriculum: we learn a lot of concepts, principles, and methodological tools, mathematical, computational, heuristic, which are fundamental to understanding and dealing with systems. And, yet, we learn virtually nothing about systems science itself. What is systems science? What are its historical roots? What are its aims? Where does it stand and where is it likely to go? These are pressing questions to us. After all, aren't we supposed to carry the systems science flag after we graduate from this program? We feel that a broad introductory course to systems science is urgently needed in the curriculum. Do you agree with this assessment?" The answer was obvious and, yet, not easy to give: "I agree, of course, but I do not see how the situation could be alleviated in the foreseeable future.

Fact Gathering for Office System Efficiency Engineering Studies

Office Work Study - Industrial Engineering

The staff members are asked to write down their job description as they feel they are doing it, under various heads, for a representative period – work, month etc. They are asked to prepare a statement of duties and responsibilities under selected heads and to make an estimate of the total attendance time devoted to each activity as well as time absorbed by miscellaneous affairs, waiting, etc.

___________________________________________

Relevant Facts


A large part of system efficiency studies consists of getting facts.  The fact collection must be done selectively and as economically as possible. In gathering facts, the nature and amount of work, its purpose, the people who do it, the place and time of doing it, and the methods used are to be ascertained.

Nature


What is done?
The process and the result are to be recorded.

Amount


Can a measure be found for each action?
Words and answers like ‘often’ or ‘frequently’ need to challenged and efforts are to be made to get a numerical estimate of the frequency.

Purpose


Why is the work done?

Persons


Who does the work?

Place


Where is the work done?

Time


When is the work done?

Means


How is the work done?
This includes method, movement, equipment and supervision.

 Methods of collecting and getting information


Information provided through records


Organization charts, work distribution lists, work statistics, statements of procedures and actions taken reports etc. are useful and valuable sources of information.

Job description by staff


The staff members are asked to write down their job description as they feel they are doing it, under various heads, for a representative period – work, month etc. They are asked to prepare a statement of duties and responsibilities under selected heads and to make an estimate of the total attendance time devoted to each activity as well as time absorbed by miscellaneous affairs, waiting, etc.

Direct observation of work


The system study person can himself observe procedures and record. He can discuss various steps of the procedure with the employee concerned at the time of observation.

Interview and discussion


Interviewing is a most important part of the fact collection exercise. Arrangement for an interview should always be made through, or with the knowledge of, the immediate supervisor of the person to be interviewed. The system study person should make a rough plan of the enquiry indicating the kind of information needed and the scope of enquiry based on the job description provided to him by the organization as well as the employee concerned.

During an interview the analyst should have an informal manner. He should take great trouble to put the other person at ease. He must pose his questions carefully, avoiding anything which implies criticism of the individual, or of the work done, or which may be interpreted as injuring prestige. He should be impersonal, making it clear that he is engaged upon a study of the work and is not probing into the actions of the individuals. He needs to play down any idea that he is an expert in the specific work and stress the value of the main features of efficiency study approach. It helps if he uses the term ‘we’ rather than ‘I’ in conversation and interview. He should listen patiently and attentively – but also be able to guide the conversation over the required subject matter without dominating it.

As far as possible, interviews should be time to suit the work requirements and staff convenience. Normal work should not be seriously disturbed. Incoming telephone calls, enquiries and the like must be recognized as inevitable disturbances; the extent of such interruptions, the reasons for them and the manner n which they are treated may provide useful information about the job.

The best point at which to examine work is where it is done; this may mean that interviews are undertaken by the side of the desk where the employee is functioning.

Written questionnaires


Written questionnaires can be used where more number of similar jobs are being performed to get information in a structured manner.


Discussions with senior staff


Discussion with senior staff regarding the facts recorded for each staff member may reveal additional facts.

Sampling


Sampling studies are undertaken to record relevant facts.

Industrial engineering has human effort engineering component. It consists of motion studies and design incorporating research of ergonomics and work measurement.

According to industrial engineering principles, the output of individual operators in a group can differ by 100%. Also, in a non incentive fixed payment system, operators work at 67% of the industrial engineering standard output.  That means the average worker produces output at only 67% of the standard. So a warehouse or DC operating without a formal labor management program that includes labor standards and incentives operates at about 65-70% of its potential output. This means that by adopting labor standards and payment systems that compensate workers for their productivity compared workers in other establishments, warehouses can improve  labor productivity by 30-35%, without burdening workers.

Motion Studies

While the mere act of measuring workers has proven to increase performance, the real productivity gains come from getting everyone doing the right tasks the right way. For example, if you have 100 workers in your DC, you will have 100 different ways in which the workers will do their jobs, if you have not specified particular methods. What are the chances that every one of them is the most efficient? The answer is ZERO. Motion study attempts to record the way motions are performed to do various tasks in the warehouse, and evaluates them to find out best practices of the operators. Then the best practices can be specified as standard methods. Apart from that motion studies can assess even the best practice in terms of certain principles of motion economy. When there is a need they improve the present best practice further. Thus motion studies improve productivity.

Motion study based job design and the development of standards is not necessarily something a warehouse management system will do for you. System-directed work from the system can accomplish the "right tasks" part, but getting everyone to do their tasks the "right way" is more complicated. It requires good motion design, and creating fair and accurate labor standards to measure the workers against these methods.

Man-Machine Task Improvement

Motion study has its focus on the motions performed by a worker. But is he doing task with proper tools, machines or equipments and machine movements?. Operation analysis and process improvement methods of industrial engineering contribute in eliminating waste in man-machine tasks.

By using experienced industrial engineers to study your jobs, equipment, and environment, the single most efficient method for completing each job and task can be determined. This critical steps of developing preferred methods, motions and engineered standards, along with proper training and change management, provides a quantum jump in productivity in companies.

Assigning Right Tasks to Reduce Time Taken to do Multiple Tasks

 Task interleaving:
Once you know how long it should take to complete each task based on preferred methods and engineered standards, you can leverage this information in a number of ways to improve labor productivity and utilization. System-directed task interleaving, also known as dynamic task management, is an automated function that allots tasks to workers by optimizing total time taken. Workers waste time if they have to travel back and forth from a central location to pick up their next assignment. By utilizing task interleaving, workers are directed to their next task from the location where they completed the present task,  based on priorities, proximity and their qualifications. With system-directed work, workers receive their next assignment on their mobile devices as soon as the previous task is completed, eliminating wasted travel. For example, a forklift driver replenishing an item in racks might be directed to pick a nearby pallet and take it to a loading dock or return a stack of empty pallets to a palletizer as the next task.

Also, by intelligently grouping picks into "batches" modern warehouse management solutions can significantly increase picking efficiency by enabling workers to pick multiple orders at the same time. This reduces travel and order fulfillment times.

Slotting


In warehousing, slotting is the intelligent positioning of merchandise for the purpose of optimizing order fulfillment efficacy. Slotting involves identifying the most efficient placement for each item in a distribution center or warehouse.

If the inventory in your DC has any degree of seasonality, if you support weekly/monthly campaigns for promotional item fulfillment, or if you have a fair amount of new SKU introductions into your facility, you could benefit substantially from placing them in forward racks or pick areas. Proper slotting of high velocity SKUs can significantly reduce pick travel time as well as minimize pick-line congestion, thus making pickers much more productive.

Slotting tasks can be handled  by the warehouse management solution, such that any re-slotting is minimum and decisions related to reslotting are also taken in an optimal way.                    

MAKING THE SYSTEMS WORK FOR YOU

No one process or system will single-handedly maximize your productivity.

Could your DC layout better facilitate your current and future operations? Do you have industrial engineers trained in developing preferred methods and engineered standards? Who will handle the critical change management process?

System Efficiency Engineering - Interesting Web Pages and Reports

Efficiency improvement is also referred to by the term cost reduction. Efficiency improvement is not directly aiming revenue expansion but it is focusing on supply chain efficiency with respect to an accepted marketing or sales goal of the organization. But as efficiency improves and cost is reduced, the organizations may be able to lower prices and get more revenue for product that have elastic demand. But the immediate focus of system efficiency project is improvement in efficiency within the context of a targeted production and sales plan.
Industrial engineering is a discipline that focuses on improving the efficiency of  production and distribution systems.

Physical Internet - Efficient Sustainable Logistics Movement

Universal interconnection of logistics services


Physical Internet where goods travel in modular containers for the sake of interconnection in open networks. 



Ballot, E, B. Montreuil and F. Fontane (2010).

Topology of Logistic Networks and the Potential of a Physical Internet



CGS-Production and Logistics Systems, École des Mines de Paris, France et CIRRELT, Université Laval, Québec, Canada


Abstract : The topology of the logistic networks that contribute contemporary logistics is minimally examined or challenged in the assessment and improvement of the performance of supply chains, logistic and freight transportation. In this paper, it is shown that the topology of logistic networks has a major performance impact and that it can be significantly improved if the actual organization of flows is substituted by an organization founded on the universal interconnectivity of logistic networks: the Physical Internet.

The performance of contemporary vs. Physical Internet enabled network topologies is measured and contrasted through transportation throughput requirements, flow travel, and total costs.

Towards a Physical Internet: Meeting the Global Logistics Sustainability Grand Challenge


Logistics Research, Vol. 3, No. 2-3, p. 71-87.


Abstract : This paper starts with the assertion that the way physical objects are currently transported, handled, stored, realized, supplied, and used throughout the world is unsustainable economically, environmentally, and socially. Evidence supporting this assertion is exposed through a set of key unsustainability symptoms.

It suggests exploiting the Digital Internet metaphor to develop a Physical Internet vision toward meeting this grand challenge. The paradigm breaking vision is introduced through a set of its key characteristics. The paper then proceeds with addressing the implications and requirements for implementing the Physical Internet vision as a means to meet the grand challenge.

It concludes with a call for further research, innovation, and development to really shape and assess the vision and, much more important, to give it flesh through real initiatives and projects so as to really influence in a positive way the collective future.

Functional Design of Physical Internet Facilities: A Road-Rail Hub 


in Progress in Material Handling Research: 2012, MHIA, Charlotte, NC (2012).


Abstract : Montreuil, Meller and Ballot enumerated the type of facilities that would be necessary to operate a Physical Internet (PI, π), which they termed, “π-nodes.”

This paper is part of a three-paper series for the 2012 IMHRC where the authors provide functional designs of three PI facilities. This paper covers a PI road-rail hub. The purpose of a PI road-rail node is to enable the transfer of PI containers from their inbound to outbound destinations. Therefore, a road-rail π-hub provides a mechanism to transfer π-containers from a train to another one or a truck or from a truck to a train. The objective of the paper is to provide a design that is feasible to meet the objectives of this type of facility, identify ways to measure the performance of the design, and to identify research models that would assist in the design of such facilities. The functional design is presented in sufficient detail as to provide an engineer a proof of concept.

Functional Design of Physical Internet Facilities: A Unimodal Road-Based Crossdocking Hub


in Progress in Material Handling Research: 2012, MHIA, Charlotte, NC (2012).


Abstract : As part of the 2010 IMHRC, Montreuil, Meller and Ballot proposed a set of facility types that would be necessary to operate a Physical Internet (PI, π), which they termed π-nodes. This paper is part of a three-paper series for the 2012 IMHRC where the authors provide functional designs of three PI facilities. This paper covers a unimodal road-based crossdocking hub designed specifically to exploit the characteristics of Physical Internet modular containers so as to enable the efficient and sustainable transhipment of each of them from its inbound truck to its outbound truck. The objective of the paper is to provide a design that is feasible to meet the objectives of this type of facility, identify ways to measure the performance of the design, and to identify research models that would assist in the design of such facilities. The functional design is presented in sufficient detail as to provide an engineer a proof of concept.


First work in the field of flows transportation

Interconnected logistic networks and protocols: simulation-based efficiency assessment, 


in International Journal of Production Research (2013).


Abstract : Logistic networks intensely use means of transportation and storage facilities to deliver goods. However, these logistic networks are still poorly interconnected and this fragmentation is responsible for a lack of consolidation and thus efficiency. To cope with the seeming contradiction of just-in-time deliveries and challenging emissions targets, a major improvement in supply networks is sought here.

This new organisation is based on the universal interconnection of logistics services, namely a Physical Internet where goods travel in modular containers for the sake of interconnection in open networks.

If from a logical point of view, merging container flows should improve efficiency, no demonstration of its potential has been carried out prior to the here reported research. To reach this potentiality assessment goal, we model the asynchronous shipment and creation of containers within an interconnected network of services, find the best path routing for each container and minimise the use of transportations means. To carry out the demonstration and assess the associated stakes, we use a set of actual flows from the fast-moving consumer goods sector in France. Various transportation protocols and scenarios are tested, revealing encouraging results for efficiency indicators such as CO2 emissions, cost, lead time, delivery travel time, and so forth.

As this is a first work in the field of flows transportation, the simulation model and experiment exposes many further research avenues.
