摘要:

People's social and economic desires are gradually becoming more versatile and fragmented. Industries should be developed in such a way that these versatile human desires are brought into harmony with the organizational needs of production engineering.

摘要:

The learning curve is one of the tools in operation planning and control. It enables the planner to estimate future performance of tasks executed either by individuals or organizations. In fact, every task is composed of elements, or subtasks. Therefore, the learning curve of the task is derived from the learning curves of the component elements and their frequency within the task. The paper discusses the nature of the aggregated learning curve as well as ways to calculate the values of its parameters. The nature of the aggregated learning curve is found to be different from its components (that is, the value of its parameters and its equation are not the same).

摘要:

AUTOMAT consists of a range of computer techniques which can assist the Work Study Engineer in the design and evaluation of manual work tasks. AUTOMAT provides a means for introducing MTM at any level of detail with a reduction in the time and cost taken to produce analyses. Since the computer allows the work study engineer to describe an operation using a high-level language while producing output at the detailed MTM-2 level, the time spent on clerical work and calculations is significantly less. The program itself provides a means of studying methods with a view to improvement, and a by-product of using the computer is a high level of consistency.

摘要:

In this paper an attempt has been made to develop a method for the allocation of system reliability to system components. The method is adapted to the systems in mechanical engineering. It takes into account changes in environmental conditions, changes in work processes and also some previously developed methods. The method has been developed by introducing the proportionality coefficient, failure rate of the ‘weakest’ system component, and the significance degree of the system component Et.

摘要:

Programming costs occupy a significant ratio to machining costs when any prototype with complicated forms is tentatively machined. The ratio of the programming cost to the total processing cost will become a more considerable amount as its shape is more complicated, or as its lot size is smaller.

摘要:

In all manufacturing and service industries the layout of facilities is an important determinant of operating efficiency and costs. Whenever the flow of materials or people is complex, computerized procedures offer the only feasible means of developing and evaluating alternative arrangements.

摘要:

Existing cluster analysis methods are reviewed and a new approach using a rank order clustering algorithm is described which is particularly relevant to the problem of machine-component group formation. A relaxation and regrouping procedure is developed whereby the basic rank order clustering method may be extended to the case where there are bottleneck machines.

摘要:

Many Production Managers are faced with the problem of planning production, inventory and work force under the constraint of limited resources to meet a seasonal demand. Considerable research has been done on this planning problem and various models have been proposed. The linear decision rule (LDR), especially as applied to the well-known Paint Shop, represents a milestone in the development of such models and serves as a standard against which the performances of many other models are measured.

摘要:

In the Japanese automobile and electrical industries it is often necessary to consider the production ordering systems as multi-stage production inventory systems. Previous analyses of production ordering systems have left untouched the variations in the production ordering quantities and inventory at each stage, in spite of the fact that the amplification phenomena of these variations are critical in a multi-stage production inventory system. Generally, we are able to classify the multi-stage production ordering systems into two types, i.e. the push-type and the pull-type. This paper discusses the following subjects concerning the push-type and multi-stage production ordering system based on forecasting: (1) the effects of demand fluctuations and forecast errors on the amplification of production order variations and inventory variations in terms of a basic production ordering model, and (2) the same effects in a modified production ordering model which is able to decrease both the variations in the production ordering quantities and in the inventory at each stage.
