摘要:

A cyclical combined manual and decision task was examined at an elemental level to determine the effects of task difficulty and informational load upon task performance. The index of difficulty as a measure of task difficulty and the uncertainty in task information as a measure of informational load were varied. Ten young and ten older industrial workers participated in the study. Performance, decision and movement times were measured. It appears that a high information load affects to delay the decision processes of the older worker.

摘要:

In this paper, a general mathematical model for capacity decision-making is a developed. The model attempts to determine the optimal sizes of capacity step additions and also the optimal timings for these additions. The model is built with independent variables such as a general demand function, a general price function, the experience curve coat coefficient, the technological improvement cost coefficient, capacity shortage costs plus overcapacity costs, discount rate, length of planning horizon, and others. A computer algorithm has been developed to solve this model that has (2N + 2) simultaneous nonlinear equations with (2N + 2) unknowns, where N is the proposed number of capacity step additions. The computer output includes optimal number of capacity steps, their optimal sizes, and also the optimal timings of their additions. In all, 390 combinations of input parameters are analysed, and the resulting conclusions are discussed.

摘要:

This paper deals with the problem of finding the optimal schedule for producing, with a probability α, a finite numberH, of parts which have a diameter within specified tolerance limits. It is assumed that the diameter is a normally distributed variable that exhibits a linear trend in the process mean. The solution involves determining the optimal run size(s), as well as the specific number of runs of each size, required to produce at leastHparts, with probability α, at minimum cost. A solution algorithm is provided and computational experience reported.

摘要:

The application of robots to industrial assembly processes raises issues of robot selection and product design which are just beginning to be addressed in the research literature. This paper describes a framework of analysis which can assist product designers and production engineers in selecting economic combinations of alternative product designs and assembly robots.

摘要:

This paper suggests a new multidimensional classification method (CMDC-II), which is a method for finding the design rules of effective work groups by determining rational combinations of workers, tasks and supervisors. The CMDC-II is a new method for providing design rules from the viewpoint of design goal attainment. The features of our methodology are summarized as follows.
