摘要:

Local buffers at the work stations in moat flexible manufacturing systems have very limited storage capacity and, consequently, parts attempting to enter the work stations may be blocked. Parts routing that follows a dynamic scheme adapted to the state of the system is also desirable. A set of models has been developed to accommodate these features of real systems. The models have easily computable solutions, and with small local buffers are robust to various processing-time distributions. For systems with large local buffers, they can readily incorporate the exponentialization approach to yield accurate results.

摘要:

The manufacturing processes required to make an engineered part must be selected with consideration to cost, producibility and quality. Process planning, which is selection of the most appropriate production processes, is both an art and a science. Several process-planning software systems for mainframe computers are currently available. In this paper, process planning with the aid of a microcomputer is discussed. The computer program developed is used in an interactive mode and written in MBASIC. In this software development, the geometrical programming technique is used for the selection of optimal machining parameters.

摘要:

The use of fuzzy methodologies is an efficient way of accounting for vagueness in human judgment. This paper illustrates potential applications of fuzzy methodologies to various areas of production management including new product development, facilities planning, human production management, production scheduling and inventory control, quality and industrial process control, and cost/benefit analysis. In addition, important areas for new research are discussed.

摘要:

An efficient single-pass heuristic method capable of finding good solutions for the single-model deterministic line balancing problem is presented. The method involves four phases for simplifying a given problem, reducing its size and decomposing it into smaller subproblems when appropriate. The solution is then found by using combinations of various heuristic rules. The procedure is illustrated on the 70-task problem of Tonge (1960)and computational results on well-known test problems are reported.

摘要:

Traditionally the grinding process has been a finishing process and the operating parameters and the results obtained in this mode are well known. However, there is an increasing demand for the use of high rates of metal removal grinding and when allied with the application of adaptive control this has highlighted a need to be able to predict the forces that will be generated during grinding operations. The work reported is part of an overall programme to study the effects of different dressing tools, wheelspeeds, metal removal rates and dress leads on grinding ratio, surface finish and grinding forces. From the results obtained for grinding forces it will be shown that various factors in the dressing and grinding operations influence the initial and subsequent levels of grinding force. These factors are discussed and empirical formulae developed to predict levels of normal and tangential force during grinding. The developed formulae utilise commonly specified parameters in the grinding process and are more easily applied than those of other researchers which rely on measurements obtained during testing.

摘要:

The efficiency of an automatic transfer line can be improved by providing buffers between stages and/or installing redundant machines at selected stages. In this paper, two two-stage production-line systems where a buffer storage is provided between the production stages, are discussed. Each production stage consists of two machines in either a splitting or a stand-by arrangement.

摘要:

This is the first of two papers describing an approach to assessing the effectiveness of production control systems in defined company types. A method of classification according to production control complexity is developed, leading to the definition of six basic company classifications within the engineering batch-manufacturing sector. It is proposed that these groups should form the basis for a standardized approach to system design; this will be discussed further in the second paper.

摘要:

An algorithm based on incremental cost approach for determining the optimal production policy in case of single-product discrete lot sizing is developed. This algorithm is extended to multi-product discrete lot sizing with capacity and inventory constraints when the capacity is specified in time units. Both the algorithms developed are illustrated with examples.
