Book excerpt: Group Technology and Cellular Manufacturing (GT/CM) have been widely-researched areas in the past 15 years and much progress has been made in all branches of GT/CM. Resulting from this research activity has been a proliferation of techniques for part-machine grouping, engineering data bases, expert system-based design methods for identifying part families, new analytical and simulation tools for evaluating performance of cells, new types of cell incorporating robotics and flexible automation, team-based approaches for organizing the work force and much more; however, the field lacks a careful compilation of this research and its outcomes. The editors of this book have commissioned leading researchers and implementers to prepare specific treatments of topics for their special areas of expertise in this broad-based philosophy of manufacturing. The editors have sought to be global both in coverage of topic matters and contributors. Group Technology and Cellular Manufacturing addresses the needs and interests of three groups of individuals in the manufacturing field: academic researchers, industry practitioners, and students. (1) The book provides an up-to-date perspective, incorporating the advances made in GT/CM during the past 15 years. As a natural extension to this research, it synthesizes the latest industry practices and outcomes to guide research to greater real-world relevance. (2) The book makes clear the foundations of GT/CM from the core elements of new developments which are aimed at reducing developmental and manufacturing lead times, costs, and at improving business quality and performance. (3) Finally, the book can be used as a textbook for graduate students in engineering and management for studying the field of Group Technology and Cellular Manufacturing.

Available in PDF, EPUB and Kindle. Book excerpt: Batch manufactcring is a dominant manufacturing activity in the world, generating a great deal of industrial output. In the coming years, we are going to witness an era of mass customization of products. The major problems in batch manufacturing are a high level of product variety and small manufacturing lot sizes. The product variations present design engineers with the problem of designing many different parts. The decisions made in the design stage significantly affect manufacturing cost, quality and delivery lead times. The impacts of these product variations in manufacturing are high investment in equipment, high tooling costs, complex scheduling and loading, lengthy setup time and costs, excessive scrap and high quality control costs. However, to compete in a global market, it is essential to improve the productivity in small batch manufacturing industries. For this purpose, some innovative methods are needed to reduce product cost, lead time and enhance product quality to help increase market share and profitability. What is also needed is a higher level of integration of the design and manufacturing activities in a company. Group technology provides such a link between design and manufacturing. The adoption of group technology concepts, which allow for small batch production to gain economic advantages similar to mass production while retaining the flexibility of job shop methods, will help address some of the problems.

This book was released on 2013-08-23 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on a development of optimal, flexible, and efficient models and algorithms for cell formation in group technology. Its main aim is to provide a reliable tool that can be used by managers and engineers to design manufacturing cells based on their own preferences and constraints imposed by a particular manufacturing system. This tool could potentially lower production costs by minimizing other costs in a number of areas, thereby increasing profit in a manufacturing system. In the volume, the cell formation problem is considered in a systematic and formalized way, and several models are proposed, both heuristic and exact. The models are based on general clustering problems, and are flexible enough to allow for various objectives and constraints. The authors also provide results of numerical experiments involving both artificial data from academic papers in the field and real manufacturing data to certify the appropriateness of the models proposed. The book was intended to suit the broadest possible audience, and thus all algorithmic details are given in a detailed description with multiple numerical examples and informal explanations are provided for the theoretical results. In addition to managers and industrial engineers, this book is intended for academic researchers and students. It will also be attractive to many theoreticians, since it addresses many open problems in computer science and bioinformatics.

Abstract: ABSTRACT of THESIS A Holistic Approach to Designing Cellular Manufacturing Systems Submitted by Lau Ka Wing for the degree of Master of Philosophy at the University of Hong Kong in December 2004 Cellular Manufacturing Systems (CMSs), which are based on the concept of Group Technology (GT) have been recognized as an efficient and effective way of improving productivity in factories. In recent years, many researchers have tried to find ways of improving CMSs. Most of them have concentrated on distinguishing the part families and machine cells either simultaneously or individually, with the objective of minimizing total intercellular and intracellular part movements. This is known as a cell formation problem (CFP), and is a crucial process in the design of a CMS. Besides considering simple CFPs, some researchers have also focused on machine flexibility, in which parts are having alternative routings/process plans. However, it is very rare to consider the area of aggregation and disaggregation of machines during cell formation under some uncertain constraints. i The first part of this study addressed the design of a CFP holistically, taking into account machine flexibility as well as machine aggregation and disaggregation. Based on the availability of alternative routings, a method was proposed to generate an alternative solution for machine breakdown situations. The aim of this model was to form machine cells and part families so as to minimize the intercellular and intracellular part movements. In practice, as some components may not be finished within only one cell, they have to travel to other cells for further operations. Under such circumstances, intercellular part movement will occur. Different sequences of machine cells may result in different total intercellular movement units. A method was therefore proposed in the second part of the study for solving inter-cell layout problems (IECLPs) based on the results previously obtained. In this part, the impact of inter-cell layouts on minimizing intercellular movement units was studied. Parts moving within cells are called intracellular part movements. The sequences of machines within cells are very important from the point of view of reducing total intracellular part movement units. However, little research into these intra-cell layout problems (IACLPs) has been carried out. In the third part of the study, a method of handling all the sequences of machines within each existing cell and the sequence of the existing cells simultaneously was suggested. The aim of the solution to the intra-cell and inter-cell layout problem (IAECLP) ii addressed in this part of study was to minimize total intracellular and intercellular part movements. It is noted that IECLPs and IAECLPs are considered as quadratic assignment problems (QAPs). Since CFPs and QAPs have already been proved to be NP-complete, a genetic algorithm (GA) is employed through the study, as it performs better for complex optimization problems. The holistic approach proposed in this study will lead to the development of vertical integration from cell formation to intra-cell and inter-cell layouts. In other words, CMS designers will in future be able to consider IAECLPs as well as CFPs. An industrial case study was made of a steel member production company for demonstration purposes, and a comparative study ev

This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the major steps in designing cellular manufacturing systems is to form cells. This involves identification of machine groups and part families. This thesis presents a new approach for optimally grouping the original set of machines into distinct uncorrelated cells. The approach involves two phases. In the first phase, machine cells are formed by applying factor analysis to the matrix of similarity coefficients. In the second phase, integer programming is used to assign parts to the cells. Because of its mathematical basis, the approach assures an optimal cell formation through the generation of uncorrelated cell clusters and the property of variance maximization. Using data set examples, the approach was found to perform very well in terms of a number of objective criteria. Moreover, the approach compares favorably to well-known existing methods. Other advantages such as efficient computational performance, and flexibility during cell formation make this approach very powerful.

Available in PDF, EPUB and Kindle. Book excerpt: Cellular manufacturing (CM) is the grouping of similar products for manufacture in discrete multi-machine cells. It has been proven to yield faster production cycles, lower in-process inventory levels, and enhanced product quality. Pioneered on a large scale by Russian, British, and German manufacturers, interest in CM methods has grown steadily over the past decade. However, there continues to be a dearth of practical guides for industrial engineers and production managers interested in implementing CM techniques in their plants. Bringing together contributions by an international team of CM experts, the Handbook of Cellular Manufacturing Systems bridges this gap in the engineering literature.

This book was released on 1993 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular Manufacturing is the focus of considerable interest from practitioners and academics alike. One of the problems in the design of Cellular Manufacturing Systems is cell formation, which is essentially the identification of part families and machine groups. The most difficult problem is the formulation of part families and the associated cells, taking into account the need to form realistic cells of manageable size and the existence of any bottle-necks. This research assesses the appropriateness of rule-based systems for the implementation of three different techniques for formulating product families and associated cells. These three techniques are OpitzClassification and Coding, Rank Order Clustering and Direct Clustering Algorithm, and Nuclear Synthesis. Rules are developed and implemented using real factory data to illustrate the validity of rule-based system for cell formation and the applicability of different procedures to overcome the cell's bottle-neck problem. Briefly, this problem can be resolved by one of the following procedures: l. Assign the bottle-neck parts to an alternative machine. 2. Devise an alternative routing for the bottle- neck parts. 3. Subcontract the bottle-neck parts internally to another cell or cells in the shop-floor. 4. Subcontract the bottle-neck parts to another factory. 5. Redesign the bottle-neck parts to utilize the available machine types. 6. Duplicate the bottle-neck machines or purchase their alternatives. This thesis demonstrates the feasibility of using the rule-based system to.
