Productivity Science - Research Project - Causal Explanation for Productivity




“Productivity science is scientific effort, that in any specific work situation, identifies the appropriate philosophy, culture, systems, processes, technology, methods and human physical action and behavior and elements of each of them of that will maximize positive (social, environmental and economic) outcomes relative to the resources consumed.” - Narayana Rao (IISE 2020 Annual Conference  Proceedings)


Project started on 3 August 2017


The research project is exploring the research conducted so far in the industrial engineering field to identify research papers and theses (dissertations) that developed or tested causal explanation theories, propositions or hypotheses and consolidate them into a framework. The research is furthering the principles of industrial engineering proposed by Prof. K.V.S.S. Narayana Rao (Part of the Proceedings of IISE 2017 Annual Conference at Pittsburgh)

Research in Industrial Engineering can be related to productivity science, productivity engineering or productivity management. The basic research in industrial engineering has to aim of creating productivity science. The science in turn is converted into productivity engineering or productivity management. Productivity engineering is using technical knowledge to redesign products and processes. Productivity management is redesign of managerial processes to enhance productivity and planning and execution of productivity improvement strategies, plans, programs and projects.

Productivity - Definition and Explanation


Productivity is proper and rational use of resources. Productivity is measured as quality (effective or useful) output per unit of single input or unit of multiple inputs.

When productivity is increased either inputs used will come down for the same output or output will increase for the same input.  In terms of cost, for the same amount of input more output will come, hence unit cost of production will come down. Similarly, for the same output, input will come down, and hence unit cost will come down.

Philosophy of Productivity Science


We need to think of 'Philosophy of Productivity Science.' That may help us in orderly development of productivity science.


What will be the content of Philosophy of Productivity Science?

A good discussion on the role of philosophy in empirical sciences.

Philosophers are not empirical researchers, and  they are not formal theory-builders.  So what is their role in developing philosophy of various empirical sciences? Their roles are:

First, philosophers are well prepared to examine the logical and rational features of an empirical discipline.  How do theoretical claims in the discipline relate to empirical evidence?  How do pragmatic features of theories such as simplicity, ease of computation, and the like, play a role in the rational appraisal of a theory?  How do presuppositions and traditions of research serve to structure the forward development of the theories and hypotheses of the discipline?  

Second, philosophers are well equipped to consider topics having to do with the concepts and theories that economists (in general empirical scientists) employ—for example in the case of economics, economic rationality, Nash equilibrium, perfect competition, transaction costs, or asymmetric information.  Philosophers can offer useful analysis of the strengths and weaknesses of such concepts and theories—thereby helping practicing scientists to further refine the theoretical foundations of their discipline.  In this role the philosopher serves as a conceptual clarifier for the discipline, working in partnership with the practitioners to bring about more successful  theories and explanations.

So the philosopher is described as having the role of an underlaborer of the scientists.   But in fact, the line between criticism and theory formation is not a sharp one.   Philosophical expertise can facilitate significant substantive progress with regard to important theoretical or empirical problems within the disciplines.

 In order to accomplish these goals, the philosopher of an empirical science must attain a professional and rigorous understanding of the discipline as it currently exists.  The most valuable work in the philosophy of any science proceeds from the basis of significant expertise on the part of the philosopher about the best practice in that discipline, contemporary debates, and future challenges of the discipline.  Only through such acquaintance will the philosopher succeed in raising topics that genuinely engage with important issues in the profession.

Productivity Science - One Explanation

Productivity science is thus an approach to productivity measurement , analysis and improvement that attempts, in any specific situation, to identify the appropriate philosophy, culture, systems, processes, technology and methods that will maximize positive (social, environmental and economic) outcomes relative to the resources consumed.

HOW CAN I HELP INDUSTRIAL ENGINEERS TO PERFORM BETTER AS CONSULTANTS OR EXECUTIVES.

Eagerness to exploit engineering & technology developments to increase productivity = Industrial Engineering.

Industrial engineering improves machine effort and human effort in the activities or operations:

PROCESSING - INSPECTION - TRANSPORT - STORAGE - DELAYS in Engineering Processes.

PROCESSING - INSPECTION - TRANSPORT - STORAGE have engineering elements, information elements, machine effort elements, human effort elements, and managerial elements.

DELAYS are mainly due to planning and control issues, attitudes of managers and operators, breakdowns, defects etc. Toyota has done good industrial engineering in this area.

Modelling and Simulation of Sheet Metal Forming Processes

Marta C. Oliveira, José Valdemar Fernandes

MDPI, 22-Apr-2020 - Technology & Engineering - 254 pages

The numerical simulation of sheet metal forming processes has become an indispensable tool for the design of components and their forming processes. This role was attained due to the huge impact in reducing time to market and the cost of developing new components in industries ranging from automotive to packing, as well as enabling an improved understanding of the deformation mechanisms and their interaction with process parameters. Despite being a consolidated tool, its potential for application continues to be discovered with the continuous need to simulate more complex processes, including the integration of the various processes involved in the production of a sheet metal component and the analysis of in-service behavior. The quest for more robust and sustainable processes has also changed its deterministic character into stochastic to be able to consider the scatter in mechanical properties induced by previous manufacturing processes. Faced with these challenges, this Special Issue presents scientific advances in the development of numerical tools that improve the prediction results for conventional forming process, enable the development of new forming processes, or contribute to the integration of several manufacturing processes, highlighting the growing multidisciplinary characteristic of this field.

Tribology of dry deep-drawing of various metal sheets with use of ceramics tools

Surface and Coatings Technology

Volumes 177–178, 30 January 2004, Pages 582-590

S Kataoka M Murakawa TAizawa H Ike

https://doi.org/10.1016/S0257-8972(03)00930-7

Abstract

Lubricant is essential in the conventional metal forming to reduce the friction between tool and workpiece  and to prolong the tool life by prevention of galling and seizure. Use of ceramic die,  because of high tribological properties may permit dry forming. In the present paper, practical possibility of dry deep-drawing is studied using ceramic dies.  Each ceramic material has its own compatibility to sheet materials. Ceramic dies can be applied to deep-drawing of mild steel and pure copper sheets with success, while they failed to be utilized for titanium sheet.  In case of deep-drawing for metal-alloy sheets, pretreatment to form the adhesive tribo-coating is effective to improve the workability when using alumina and zirconia dies. 


Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication, and wear. Tribology is interdisciplinary and it draws on many academic fields, including physics, chemistry, materials science, mathematics, biology, and engineering. People who work in the field of tribology are referred to as tribologists.

Ceramics

2019

Ceramic tool inserts have extreme hardness for wear resistance, high heat resistance, and optimum tribological behavior, but have poor machinability and severe brittleness. High costs are offset by reduced maintenance and increased productivity. While not commonly used, the ceramic tool inserts offer a possible solution to high interface loading and wear.
