摘要:

The usual criterion of choice between preventive and contingency maintenance, availability, is restrictive in the sense that improvement is, even in ideal circumstances, at most of the order of 10%. Economic criteria are shown to obtain optima at values that do not maximize availability but show better percentage increases in net revenue rate or percentage decreases in maintenance cost.

摘要:

Reporting on results of a job-enrichment programme applied to an automotive assembly operation, Ruehl (1974), attributes significant savings to the impact of reduced labour turnover on training coat. Despite higher skill requirements entailing longer training time, net cost was reduced rather than increased.

摘要:

Swedish experience of changes of payment systems indicates that there is a strong link between payment-by-results and the way the work organization functions. In fact the efficiency-promoting effects of payments-by-results to a great extent is explained by positiveindirect effectson work forms, production planning and control, supervision and the readiness at the shop floor level to counteract and neutralize production disturbances and variations. This paper takes account of material from a study by Dr. Jan Edgren of changes in the payment system on the development, of events at a Granges die-casting shop. It is pointed out that the indirect effects of payment systems make payment-by-results a strategic factor or leading system in the development of the shop floor organization and work forms. The paper also presents an outline of some characteristics of the payment systems of the future.

摘要:

A distinction is made between the technical details of pay plans and the decision process that is used in developing and administering them. Data are presented which show that pay plans which are identical in technical details can produce quite different results in terms of motivation and satisfaction. It appears that when employees are active participants in the development and administration of pay plans, plans are more likely to be successful. Several studies are cited which support this point and it is argued that the reasons for this include the fact that participation increases employee trust of a pay plan. Finally, it is pointed out that pay can serve as a change agent in organization development efforts if the efforts begin with and involve employees participating in pay decisions.

摘要:

Any study of labour allocation must take into account the fact that the industria structure of the economy is bound to change over time and that, this will put pressure on each kind of labour to redistribute itself continuously. Differing rates of labour-saving technical progress will have the same effect. Since labour is hardly perfectly mobile, this implies that its allocation should be regarded as essentially a disequilibrium process and that dynamic criteria should replace the usual comparative static criteria of efficiency. The purpose of this paper is to outline such a treatment.

摘要:

Confusion exists in the manual lifting and handling literature between the effects of working height at the bottom and top of a lift. This study varied both heights and measured the maximum weight lifted for male and female subjects using a non-compact box. Both bottom and top height affected weight lifted. The actual weights lifted and the relationships between male and female performance were consistent with the literature. It was found that the maximum voluntary strength at the top of the lift was not a good prediction of performance, suggesting that skill as well as strength define performance limits for this task. The implications for performance models are discussed.

摘要:

A deterministic simulation study of a complex machine shop consisting of 69 work centres is presented. The purpose of the simulation study was to develop a planning tool to evaluate effects on overtime, work centre bottlenecks, in-process inventory buildup, delivery delays and other output variables caused by individual part delays of different load mixes, modifications in work centre capacities, installation of more automated machinery, and modification in scheduling rules.

摘要:

Given the objective of determining the degree of part commonality in a product line, this study discusses several methods of analysis which are possible. The use of the entropy measure, H= − σpi log pi, is investigated as a plausible alternative to current procedure. The methodology will incorporate a simulation of several types of distributions of part usage which might occur in a typical application. An analysis of the results will compare the entropy approach with existing practice.

摘要:

Experiments are described for the one-sided unconstrained indentation of half-hard and annealed aluminium strip with a wedge-shaped tool. The mechanics of the process are described and the end-rotation, which occurs after a certain critical penetration has been reached, is measured. At the present time there is no slip-line field solution which predicts this phenomenon.

摘要:

The built-up edge formation in cutting, and the groove wear of the tool, are factors responsible for variation of surface roughness from the ideal value. The significance of these two factors have been studied statistically using multiple correlation technique. The built-up edge, when it is present, is found to affect surface roughness to a greater extent than groove wear.
