摘要:

Correlation theory is applied to a production system to evaluate its potentialities for the measurement of work-flow rates. Results obtained by this method are compared with those obtained from a, two-month shop-floor study and the agreement is good. The wider implications of the approach for production control are discussed.

摘要:

This paper describes a, general model for planning work flow through a multiprocess production system and proposes a new practical scheme of control for scheduling. The features of the model are based on experience of a wide variety of industries and a means is considered for resolving the conflicts between different objectives such as meeting due dates and reducing work in progress. The control system presumes that only the inlet times of the jobs into the production system can actually be decided and managed by a production planner, and not the subsequent internal operation start times, as previous studies have often assumed. A method for optimizing the schedule is developed on the basis of this form of control and it is illustrated on a small example. Finally implementation factors and extensions are discussed.

摘要:

The article reviews the work of the Department of Engineering Production in the development arid application of group technology. The Department was one of the first in. Britain to become involved in this subject, and of recent months a major research commitment has begun in this novel production philosophy. Croup technology is concerned with the exploitation of the sameness of components, and of their related manufacturing operations. This review examines research work in this area which has been concerned with: (i) fundamental questions, (ii) international studies, and (iii) industrial applications.

摘要:

Mathematicians have long amused themselves with very difficult problems that are treated as puzzles. One of the more recent of these is the travelling-salesman problem. During last two decades several methods have been developed for solving the travelling-salesman problem, which is akin to many other important problems. The problem of determining a manufacturing schedule, when a number of products are to be manufactured over a production facility, is identical to the travelling-salesman problem. This paper discusses a simple approach to the solution of such production scheduling problems.

摘要:

The results of optimization of multi-pass turning using a computer programme are described. By graphical presentation, the variations in cutting conditions, i.e. speeds, feeds and depths of cut for two consecutive passes are described, together with the degree of optimality in terms of the total machining cycle time, and power requirements.

摘要:

The deterministic M-stage scheduling problem is reviewed and critically appraised from the points of view of variety, contents, assumptions, recent solution procedures and criteria of optimality. The complications of practical problems are discussed to explore the true nature of the problem formulation. Several implications of the present formulation of scheduling problem are discussed and directions for future research in scheduling theory are suggested.

摘要:

An average error method is proposed to be the measure of straightness and flatness. It is shown to be better than the existing maximum error method.

摘要:

A brief review of available manufacturing systems is followed by an analysis of the problems faced by a company in the manufacture of components. The various manufacturing systems are then examined to see how well they solve the problems listed. It is deduced that a Group Technology approach provides the most efficient solution for the multi-component batch production factory and a discussion of the Group Technology approach is given.
