Book excerpt: Cellular manufacturing (CM) has emerged because of the need for manufacturing organizations to supply products that require more customization and that have shorter product life cycles and times to market. This shift from mass production to demands for mid-volume and mid-variety product mixes has shown that traditional manufacturing systems relying on functional or line layouts are not efficient and flexible enough. CM is an alternate manufacturing system combining the high throughput rates of line layouts with the flexibility offered by functional layouts (job shops). The benefits include reduced set-up times, material handling, in-process inventory, better product quality and market response time. The benefits of CM can only be achieved by sufficiently incorporating the real-life structural and operational features of a manufacturing plant when creating the cellular layout. This research presents two integrated CM models, with an extensive coverage of important manufacturing structural and operational features. The first CM model is initially formulated as a mixed integer non-linear program that incorporates multi-period production planning and dynamic system reconfiguration with deterministic production requirements. It consists of alternate process routings, the operation sequence of parts, machine duplication, machine procurement and machine capacity. Preliminary computational experiments show that only small-scale problems can be solved using the developed mixed integer non-linear program. This warrants the linearization procedures that are proposed to convert it into a linearized mixed integer programming formulation so as to solve problems of larger scale. This linearized mixed integer program is first solved using an exact solution (ES) procedure through the simplex-based branch and cut procedure of CPLEX software. Computational results are presented by solving some small-scale to large-scale numerical examples, extracted from existing literature. Although small to medium-sized problems can be solved using ES, larger ones (representing real-life sized problems) cannot be solved within reasonable computational times. A tabu search meta-heuristic is, therefore, developed to solve this mixed integer linear program. The results show that the tabu search procedure generates good quality solutions for real-life size problems within acceptable computational times. The second model addresses the same attributes as the first one but an important extension is the introduction of routing flexibility in the system by the formation of additional alternate part process routings, called contingency routings . In addition to the alternate main process routings being created for each part type, the model forms contingency routings, which serve as backups so as to effectively address the reality of part process routing disruptions, thus allowing the cellular manufacturing system to operate in a continuous manner even in the event of any breakdowns. This enhanced model is formulated as a mixed integer linear program and is then solved using the simplex-based branch and cut procedure of CPLEX (ES). The results show that the contingency and main routings can be formed simultaneously, thus bringing enhanced system and routing flexibility. The trade-off between the increased system flexibility obtained versus the additional cost to be incurred through the formation of contingency routings for all parts is discussed by comparing the solutions obtained from the model without routing flexibility and the one with routing flexibility. It is found that the enhanced system flexibility enabled by contingency routings offsets the additional system investment costs. Keywords : integrated cellular manufacturing systems design, mixed integer programming, linearization procedures, simplex-based branch and cut procedure, tabu search, routing flexibility, contingency routings, enhanced CM system flexibility.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainability is increasingly becoming a crucial concern in many aspects of life. Even though, there is a relatively growing interest from both academic researchers and practitioners in various design aspects of sustainability, one can see that design issues of sustainable manufacturing systems have not received adequate attention. Through an extensive literature review on design for sustainability and sustainability issues, it is observed that, attaining sustainability in manufacturing needs a huge amount of effort and needs to take into consideration many aspects from different perspectives. These include considering the sustainability in both the closed loop supply chain (CLSC) and the manufacturing system levels simultaneously, considering Cellular Manufacturing Systems (CMSs), considering reconfigurability for the production systems, considering Hybrid Manufacturing-Remanufacturing Systems as well as considering the recovery options such as recycling and remanufacturing. This research presents a simultaneous investigation of Reconfigurable Cellular Manufacturing Systems and Hybrid Manufacturing-Remanufacturing Systems (HMRSs), and proposes an integrated approach in design optimization, analysis, and process planning aspects as an attempt to address to a large number of design issues for Sustainable Manufacturing Systems, while the options of remanufacturing, recycling, and disposing are introduced. Four mathematical model have been developed. Third part cellular remanufacturing systems design are considered within the first model, which is initially formulated as a mixed integer non-linear program that incorporates multi-period production planning, dynamic system reconfiguration, and workforce management with deterministic production requirements. It consists the costs of machines maintenance and overhead, relocation costs for machines installation and removal, part holding cost, workers’ costs of salary, hiring, and firing, part intercellular movement cost, machine procurement cost, internal production cost, machine operating cost, the cost of acquiring the returned products, setup cost for disassembly operations, disassembly cost, the inventory cost of the returned products, parts disposal cost. Linearization procedures are proposed to convert it into a linearized mixed integer programming formulation. This linearized mixed integer program is solved using an exact solution (ES) procedure through the simplex-based branch and cut procedure of CPLEX software. The second model considered the design of cellular hybrid manufacturing-remanufacturing system, where manufacturing new products using an outsourced parts and remanufacturing using returned products are performed in the same facility by using shared resources. The overall objective of the model is to minimize the total cost of the three main categories of costs; 1) Machine cost: maintenance and overhead costs, relocation costs of installation and removal of machines, machine procurement costs, and machine operating costs, 2) Costs associated with manufacturing and remanufacturing: production costs for both new and remanufactured components, holding cost for new components, holding cost for remanufactured components, setup cost for new components, setup cost for remanufactured components, 3) Costs associated with returned products for remanufacturing: cost of acquiring the returned products, setup cost for disassembly operations, disassembly cost, and inventory cost of the returned products. Computational results and sensitivity analysis for an important design features are also reported.The third model addresses the same attributes as the second one but an important extension is the introduction of recycling (for the end-of-life parts) and disposing of the parts with no further use. In addition, the new parts production in the third model are totally depends on the recycled parts coming from the recycling center, wherein the second model it depends on the raw material purchasing from outsourcing. As the third model is the most comprehensive one, which considers a closed loop supply chain starts from a cellular hybrid manufacturing-remanufacturing system and ends with the customer zone, through the introducing of different centers like, collection, disassembly, and recycling centers, and in order to have one more step toward the design of sustainable closed loop supply chain, the fourth model are formulated. The fourth model is designed to minimize the carbon foot prints and the total cost which contains the opening costs for different centers and the transportation costs between these centersKeywords: Sustainability, Sustainable manufacturing system, cellular manufacturing systems design, Reconfigurable manufacturing system, mixed integer programming, Hybrid manufacturing-remanufacturing system, Closed loop supply chain, Reverse logistics, Carbon footprints, Facility location.

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.
