Production Control Systems

Selecting a suitable production control policy is a challenging task for managers because the superiority of one control over the other is controversial. This book analyzes pull production systems and provides a guideline to choose and implement a proper control policy in production processes. By employing a proper control policy the maximum possible throughput of the production system can be achieved with the minimum work-in-process inventory. Kanban, CONWIP, and base-stock as wellknown pull control policies are analyzed and analytical comparisons among them in multistage serial and assembly production processes are presented. Illustrated by carefully chosen examples and supported by analytical solutions, discussions provided in the book clarify the complexity of the comparisons that show there is no general superiority among the control systems. Th e book explains which structural parameters decide the superiority of one control scheme to the others, and how they are related. Given a confi guration of parameters, such as processing times and number of cards employed in the system, the superior control policy can be selected.

Focuses on the quantitative approaches necessary to computer-integrated manufacturing systems, and integrates major topics covering all phases of the production control cycle: production information processing and flow, production planning, forecasting, material requirements planning and monetary control, and scheduling. This new edition features a compendium set of 11 user-friendly computer programs for the IBM PC that enhance the teaching power of the text, allowing readers to solve real-life problems. Among programs included are growth forecasting, aggregate planning, material requirements planning, lot sizing and inventory control, and limited-resource scheduling. The chapters on scheduling give particularly thorough coverage on this difficult subject. Solutions are clearly presented, with many examples and exercises included in the text.

This Proceedings volume contains articles presented at the CIRP-Sponsored Inter- tional Conference on Digital Enterprise Technology (DET2009) that takes place December 14–16, 2009 in Hong Kong. This is the 6th DET conference in the series and the first to be held in Asia. Professor Paul Maropoulos initiated, hosted and chaired the 1st International DET Conference held in 2002 at the University of D- ham. Since this inaugural first DET conference, DET conference series has been s- cessfully held in 2004 at Seattle, Washington USA, in 2006 at Setubal Portugal, in 2007 at Bath England, and in 2008 at Nantes France. The DET2009 conference continues to bring together International expertise from the academic and industrial fields, pushing forward the boundaries of research kno- edge and best practice in digital enterprise technology for design and manufacturing, and logistics and supply chain management. Over 120 papers from over 10 countries have been accepted for presentation at DET2009 and inclusion in this Proceedings volume after stringent refereeing process. On behalf of the organizing and program committees, the Editors are grateful to the many people who have made DET2009 possible: to the authors and presenters, es- cially the keynote speakers, to those who have diligently reviewed submissions, to members of International Scientific Committee, Organizing Committee and Advisory Committes, and to colleagues for their hard work in sorting out all the arrangements. We would also like to extend our gratitude to DET2009 sponsors, co-organizers, and supporting organizations.

Since the beginning of mankind on Earth, if the "busyness" process was successful, then some form of benefit sustained it. The fundamentals are obvious: get the right inputs (materials, labor, money, and ideas); transform them into highly demanded, quality outputs; and make it available in time to the end consumer. Illustrating how operations relate to the rest of the organization, Production and Operations Management Systems provides an understanding of the production and operations management (P/OM) functions as well as the processes of goods and service producers. The modular character of the text permits many different journeys through the materials. If you like to start with supply chain management (Chapter 9) and then move on to inventory management (Chapter 5) and then quality management (Chapter 8), you can do so in that order. However, if your focus is product line stability and quick response time to competition, you may prefer to begin with project management (Chapter 7) to reflect the continuous project mode required for fast redesign rapid response. Slides, lectures, Excel worksheets, and solutions to short and extended problem sets are available on the Downloads / Updates tabs. The project management component of P/OM is no longer an auxiliary aspect of the field. The entire system has to be viewed and understood. The book helps students develop a sense of managerial competence in making decisions in the design, planning, operation, and control of manufacturing, production, and operations systems through examples and case studies. The text uses analytical techniques when necessary to develop critical thinking and to sharpen decision-making skills. It makes production and operations management (P/OM) interesting, even exciting, to those who are embarking on a career that involves business of any kind.

The papers within this volume reflect the multidisciplinary approach taken by the workshop to the development and improvement of existing production control theories and practices as applied to the process industry. Subjects covered include production planning, quality control and assurance, operational control and maintenance strategy. The development of this area is seen by those at the workshop as only being achieved by various groups working together rather than in isolation, so that the overall aim of production control is not lost in too much detail. This volume will provide the reader with essential information on new initiatives in the process industry with regard to production control.

Over the past 15 years the authors have been engaged in projects with many firms to analyse and redesign production and inventory control systems. The main purpose of this analysis and redesign was the reduction of inventory and costs, improvement of delivery performance, and simplification of the organization involved in production and inventory control. During these studies the authors became convinced that the knowledge available on the design of control systems places too much emphasis on techniques and methods, whereas the main concern should be to establish a proper control structure. This control structure should identify the main decision functions, their goals, their relationships, and the organizational position to which these decision functions should be assigned. For each decision function in the control structure, a global planning and decision procedure should be established. This book gives a comprehensive overview on the elements of a good production control structure. It examines approaches for possible structures, and how to select an adequate structure for a particular production situation. The book consists of two parts: The first part covers basic terms and ideas regarding the design of production and inventory control systems in general. The second part examines four case studies from essentially different production areas. The volume is intended for postgraduate students in such fields as production and inventory control, logistics, information systems and practitioners who are working in this field on a high organisation level.

Manufacturing process controls include all systems and software that exert control over production processes. Control systems include process sensors, data processing equipment, actuators, networks to connect equipment, and algorithms to relate process variables to product attributes. Since 1995, the U.S. Department of Energy Office of Industrial Technology 's (OIT) program management strategy has reflected its commitment to increasing and documenting the commercial impact of OIT programs. OIT's management strategy for research and development has been in transition from a "technology push" strategy to a "market pull" strategy based on the needs of seven energy-and waste-intensive industries-steel, forest products, glass, metal casting, aluminum, chemicals, and petroleum refining. These industries, designated as Industries of the Future (IOF), are the focus of OIT programs. In 1997, agriculture, specifically renewable bioproducts, was added to the IOF group. The National Research Council Panel on Manufacturing Process Controls is part of the Committee on Industrial Technology Assessments (CITA), which was established to evaluate the OIT program strategy, to provide guidance during the transition to the new IOF strategy, and to assess the effects of the change in program strategy on cross-cutting technology programs, that is, technologies applicable to several of the IOF industries. The panel was established to identify key processes and needs for improved manufacturing control technology, especially the needs common to several IOF industries; identify specific research opportunities for addressing these common industry needs; suggest criteria for identifying and prioritizing research and development (R&D) to improve manufacturing controls technologies; and recommend means for implementing advances in control technologies.
