Book Description
This paper presents a method for real-time scheduling and routing of material in a flexible manufacturing system (FMS). It extends the earlier scheduling work of Kimemia and Gershwin. The FMS model includes machines that fail at random times and stay down for random lengths of time. The new element is the capability of different machines to perform some of the same operations. The times that different machines require to perform the same operation may differ. This paper includes a model, its analysis, a real-time algorithm, and examples, Keywords: Computations; Real time loading; Problem solving; Decision making; Robotics.

Book Description
With the approach of the 21st century, and the current trends in manufacturing, the role of computer-controlled flexible manufacturing an integral part in the success of manufacturing enterprises. will take Manufacturing environments are changing to small batch (with batch sizes diminishing to a quantity of one), larger product variety, produc tion on demand with low lead times, with the ability to be 'agile.' This is in stark contrast to conventional manufacturing which has relied on economies of scale, and where change is viewed as a disruption and is therefore detrimental to production. Computer integrated manufac turing (CIM) and flexible manufacturing practices are a key component in the transition from conventional manufacturing to the 'new' manu facturing environment. While the use of computers in manufacturing, from controlling indi vidual machines (NC, Robots, AGVs etc.) to controlling flexible manu facturing systems (FMS) has advanced the flexibility of manufacturing environments, it is still far from reaching its full potential in the environment of the future. Great strides have been made in individual technologies and control of FMS has been the subject of considerable research, but computerized shop floor control is not nearly as flexible or integrated as hyped in industrial and academic literature. In fact, the integrated systems have lagged far behind what could be achieved with existing technology.

Book Description
Originally published in 1994 this book undertakes a comprehensive study dealing with the effects of machine flexibility, tool magazine capacity, varying production demands and different oeprating policies on the production planning problems. Performance measures such as FMS flexibility, makespan and inventory are used in evaluating the effects. Three measures of FMS flexibility - actual routing flexibility, potential routing flexibility and capacity flexibility are defined and operationalized.

Book Description
This book presents a unified optimal control approach to a large class of problems arising in the field of production planning and scheduling. It introduces a leading optimal flow control paradigm which results in efficient solutions for planning and scheduling problems. This book also introduces the reader to analytical and numerical methods of the maximum principle, used here as a mathematical instrument in modeling and solving production planning and scheduling problems. The book examines control of production flows rather than sequencing of distinct jobs. Methodologically, this paradigm allows us to progress from initial assumptions about a manufacturing environment, through mathematical models and construction of numerical methods, up to practical applications which prove the relevance of the theory developed here to the real world. Given a manufacturing system, the goal is to control the production, subject to given constraints, in such a way that the demands are tracked as closely as possible. The book considers a wide variety of problems encountered in actual production planning and scheduling. Among the problems are production flow sequencing and timing, capacity expansion and deterioration, subcontracting and overtime. The last chapter is entirely devoted to applications of the theory to scheduling production flows in real-life manufacturing systems. The enclosed disk provides software implementations of the developed methods with easy, convenient user interface. We aimed this book at a student audience - final year undergraduates as weIl as master and Ph. D.

Book Description
The contents of this book are based on invited papers submittedfor presentation and discussion at the 1990 Material Handling Research Colloquium held in Hebron, Kentucky, June 19-21,1990. The Colloquium was sponsored and organized by the College Industry Councilfor Material Handling Education (CIC-MHE) with addi tional co-sponsorship and funding provided by numerous organizations (see ac knowledgements). The purpose of the Colloquium was to foster open discussion about the current state of material handling research at universitiesfrom across the United States and Canada. It was an opportunity to share specific research directions and accomplishments. But more importantly, it was an opportunity to discuss the implications of the basic constraints to solving industry relevant problems in the field of material handling and closely related activities; the efficacy of the approaches being taken at the present time; and the directions believed to be of most value to the industry and to advancing the knowledge and science base of the material handling engineering discipline. The sponsoring organization, the College Industry Council for Material Handling Education was founded in 1952. The council is composed of college and university educators, material handling equipment manufacturers, distributors, users and consultants, representatives of the business press plus professional staff and members of other organizations concerned with material handling education.

Book Description
Manufacturers worldwide are faced with unprecedented challenges from international competition, changing production processes and technologies, shorter production life-cycles, market globalization and environmental requirements. Fundamental to meeting these challenges is the understanding and control of information across all stages of the Computer Integrated Manufacturing (CIM) process. Modern Manufacturing presents the state of the art in the information-oriented aspects of CIM and Intelligent Manufacturing Systems. Particular emphasis is placed on the impact of new software engineering technologies, the object-oriented approach, database design, hierarchical control and intelligent systems. The contributions are written by experts from Europe and the USA.
