Dilemmas in factory design: paradox and paradigm 15 Fig 8 University of Massachusetts IBIS... objectives/criteria {f1 (x), f2 (x), , fp (x)} involved in the FDP The implications of ∆5 and ∆6 for the manufacturing and IE profession and curriculum are that multi-criteria and multi-objective programming are essential methodological concepts and algorithmic tools in manufacturing systems and IE MCDM concepts and methodologies have slowly been introduced into IE curriculums which is a very positive sign... Decisions Reached Knowledge Gained Fig 6 Planning issues resolution process – Explanatory Issue ( i ):= There is not clear separation between the forklift trucks and the plant personnel within the receiving and shipping area Instrumental Issue (ι1 ):= If space is available, separate receiving and shipping and design the material handling systems in the plant in a U-shape layout Instrumental Issue (ι2 ):=... professions from time-to-time Paradoxically, all professions have a vested interest in their clients, but cannot be trusted to act in their clients best interests, “a conspiracy against the laity.”[21, 17] Since, the Factory Design Problem (FDP) is a very important aspect within manufacturing and industrial engineering, it became obvious that the subject matter of the keynote address and the crisis in. .. expensive in time to construct It makes eminent sense in the supply-chain business environment currently popular, so the more one understands the logistics and the manufacturing systems and processes, the better At this point, the system model Σ becomes an integral part of the new paradigm A discrete-event digital simulation model of the polymer recycling plant was constructed in order to better understand... the Analysis of Manufacturing Systems 1 where the idea of the I would like to thank the referees for their insights and suggestions and pointing out some problems in earlier drafts My approach to factory design has evolved over the years, and is still evolving, and it is largely due to the in uence of Professor Horst Rittel, my professor at the University of California at Berkeley during my formative... with identifying, explaining, and resolving of the planning issues This last principle links back to ∆1 , since the problem formulation process must start with inquiries and issues, and thus an argumentative, dynamic process through an IBIS is critical to the entire FDP process 5 Implications for the profession and the curriculum To briefly summarize and emphasize the importance of the preceding discussion,...
