The global economy and technological innovations bring many new issues and twists to the subject of computer-integrated manufacturing (CINL). It remains as broad as the complex manufacturing enterprises it attempts to model. Some persons would suggest that CIM is too broad for a single course or textbook. However, the essence of CIM is in the integration of the enterprise elements: physical integration through the linking of hardware and software systems, logical integration through shared common enterprise information and data, and philosophical integration based on a new sense of purpose and direction in every entity in the enterprise. Therefore, the integration so critical to a CIM implementation is best introduced in a single course so that links between the enterprise elements can be explored. This book was written to support such an introductory course. Understanding the operation of a comprehensive CIM solution requires some study of traditional manufacturing practice, a look at the current state of CIM, and consideration of how technology and operating procedures may change in the future. The integration of product design techniques and fundamental manufacturing principles, along with a look at changing operations and information systems that support CIM throughout the enterprise, makes this book unique. In the book, we do the following: Describe the different types of manufacturing systems or production strategies used by industries worldwide. This description is important because no two CIM solutions are the same. Go beyond the description of automated machines and software solutions because a successful CIM implementation demands more than technology. In practice, ordering hardware and software is the last step in a CIM implementation; the preliminary work is what guarantees a successful CIM project. Discuss the impact of CIM on all the major elements in an enterprise: product design, shop-floor technology, and manufacturing production and operational control systems. Provide a convincing argument for implementing CIM so that the enterprise will be competitive in the global market. In practice, the technologies available to manufacturers around the globe open every market to world-wide competition. Look at the computer-based systems of the CIM enterprise that support the growing just-in-time and lean production initiatives. In addition, the third edition has the following significant changes: Work-cell design case studies have been added at the end of chapters 1 through 4, 5, 10, and 11, with the work keyed to the concepts presented in the chapters. The chapter on CAD, chapter 4, was changed extensively to an overview of the CAD function in an enterprise and an introduction to product data management (PDM). The enterprise networking concepts were updated and expanded. The finite-element analysis and rapid prototyping sections in chapter 5 were updated and expanded. Numerous new figures have replaced older images, and many new images have been added. Also new to this edition is a CD-ROM containing the demo version of the WinMan software. This software provides its users with an opportunity to work with a fully functional computer-based enterprise resources planning (ERP) system. This tool allows users to see how a modern data-driven system can help companies better manage their operations and the related data. The CD includes a fully functional single-user system that can be installed on a PC. The demonstration takes users through the basics of the system--from the building of item and structure databases to the functions needed to manage customer orders, material management, manufacturing, and accounting information. To provide a complete overview of the computer-integrated enterprise, we divided the book into four parts. In the first part, chapters 1 and 2, we provide an overview of global competition, describe an internal manufacturing strategy, discuss in detail the problem facing manufacturing and the development of an effective solution, and characterize the operation of different types of enterprises. In the characterization, we furnish a classification and description of the manufacturing systems and production strategies used by manufacturing, provide an explanation of the product development and engineering change cycle, and give an overview of the enterprise organization. At the end of part 1, the need for change in manufacturing is made clear and a basic strategy for change in the organization is established. In addition, the description of the enterprise organization in part 1 provides a framework for the CIM concepts introduced in the rest of the text. Part 1 provides the critical introduction to manufacturing and the enterprise that is necessary for a course designed to teach CIM. In part 2, which includes three chapters, we examine the three major design and engineering process segments that take a product from concept to production. Chapter 3 introduces design and production engineering concepts and issues. The use of CIM technology to design and produce world-class products with enhanced enterprise productivity is emphasized. The old design model is compared to a recommended new process that incorporates a concurrent engineering focus to product design. This part of the text concludes with an in-depth description of production engineering functions and the opportunities for productivity gains through integration of technology and data in the enterprise. Computer-aided design (CAD) is the focus of chapter 4. Since design is the starting point for development of the product database, a full chapter is devoted to the integration of CAD into the enterprise operation. To emphasize this integration, we changed the chapter title and the content to include PDM (product data management). The function of CAD technology in the product design process is discussed, and the systems used to develop the product models are described. The importance of PDM and its link to the CAD technology and design department are covered. In chapter 5, we explore the relationships between the concurrent engineering product design model and the computer-aided engineering (CAE) technology available to support every step of the design process and production engineering. We include a complete definition of CAE, design for manufacturing and assembly, finite-element and mass-properties analysis, rapid prototyping, group technology, computer-aided process planning, computer-aided manufacturing, production and process modeling and simulation, maintenance, automation, and product cost analysis. In the final section of chapter 5, we describe the computer network used to tie the design and production engineering functions to the common enterprise database and other business functions. Part 3 of the text shifts the CIM focus to controlling the enterprise resources. CIM is alive and growing in applications that support the management and control of the enterprise. The first chapter in the sequence, chapter 6, describes the concept of manufacturing planning and control (MPC) with a model of a typical MPC system. The function of manufacturing planning and a high-level look at the systems and technologies available for CIM implementations are presented. Attention is given to the high-level system elements of production planning and the master production schedule (MPS). Chapter 6 provides an overview of the critical concepts that are explored in more detail in the following two chapters. In chapter 7, three key elements in the MPC model are discussed in more detail. These include material requirements planning (MRP), capacity requirements planning (CRP), and the production activities that execute the material and capacity plans. Automation software used to implement CIM in this critical part of the enterprise is introduced and explained. Software solutions fo
