Cellular Manufacturing Systems


Book Description

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.

Handbook of Cellular Manufacturing Systems


Book Description

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.

Reorganizing the Factory


Book Description

Winner of the 2003 Shingo Prize! Reorganizing work processes into cells has helped many organizations streamline operations, shorten lead times, increase quality, and lower costs. Cellular manufacturing is a powerful concept that is simple to understand; however, its ultimate success depends on deciding where cells fit into your organization, and then applying the know-how to design, implement and operate them. Reorganizing the Factory presents a thoroughly researched and comprehensive "life cycle" approach to competing through cellular work organizations. It takes you from the basic cell concept and its benefits through the process of justifying, designing, implementing, operating, and improving this new type of work organization in offices and on the factory floor. The book discusses many important technical dimensions, such as factory analysis, cell design, planning and control systems, and principles for lead time and inventory reduction. However, unique to the literature, it also covers in depth the numerous managerial issues that accompany organizing work into cells. In most implementations, performance measurement, compensation, education and training, employee involvement, and change management are critically important. These issues are often overlooked in the planning process, yet they can occupy more of the implementation time than do the technical aspects of cells. Includes: Why do cells improve lead time, quality, and cost? Planning for cell implementation Justifying the move to cells, strategically and economically Designing efficient manufacturing and office cells Selecting and training cell employees Compensation system for cell employees Performance and cost measurement Planning and control of materials and capacity Managing the change to cells Problems in designing, implementing, and operating cells Improving and adapting existing cells Structured frameworks and checklists to help analysis and decision-making Numerous examples of cells in various industries
