This is a study on the relationship among various group integrative determinants for group work in the manufacturing industries. The following hypotheses were built up, and a questionnaire was conducted on the people who were engaged in group work as the leader or an ordinary member. Hypotheses : Relationship among the group integrative determinants is different between the leader and ordinary members. It also varies depending on group size. Among some specific determinants, however, a general relationship exists regardless of group size. So the teamwork determinants can be extracted from the group integrative determinants. Results of the questionnaire were then examined by statistical tests, principal component analysis and their regression. As a result, the above hypotheses were confirmed to be appropriate.

In this paper, a method of generating a set of approximate nondominated schedules for any multiobjective scheduling problem is proposed, developing the multiobjective scheduling method using random sample scheduling. The proposed method is applied to a single machine scheduling problem to minimize both total flow time and maximum tardiness. The results of some experimental simulations show that the proposed method requires less computation time than the existing method using random sample scheduling does, for providing a set of approximate nondominated schedules with sufficient accuracy.

This paper presents a mathematical model to obtain the optimum equipment series under the case where demand increases linearly in the beginning and reaches a constant value. First, the equipment series after demand reached a constant value are determined by annual worth method based on like-for-like replacement. Then, the optimum equipment series are determined by the present worth method considering the total cash flows. The proposed method is applied to a simple numerical example.

A great change in social and economic environment of the work system is forecast. And a change in the meaning of work is unavoidable. So a research on the quality of working life from new viewpoints is required. We have built a multi-motivation theory from such a standpoint. In this study as part I, we examined the Double Dual Systems that is a fundamental structure of the MM theory.

The purpose of this paper is to confirm that the most fundamental and basic psychological trait of Japanese is the faith in "the feeling of togetherness". The theories of Motoori, Nakane, Okonogi, Doi, Minamoto, and Kimura on the human relations of Japanese are examined. The psychological traits that they propose as the Japanese basic psychological trait are discussed and it is confirmed that their traits are deduced on the basis of the faith in "the feeling of togetherness". Therefore, it is concluded that the most fundamental and basic psychological trait of Japanese is the faith in "the feeling of togetherness".

This paper presents a method of designing an efficient production planning system under multiple criteria. First, a basic production model can clarify the relationship between the production planning rules and the buffer inventory role in terms of impact on the system performance : shortage of products for marker demand, average inventory level, ratio of setup time, and deviation in production rate. Second, based on the results of analysis, this paper presents a method for selecting an appropriate production planning rule and setting an adequate buffer inventory level, if policies concerning the production are given.

In the VDT tasks where more than 10 seconds of system response time are required, it is said that operators had better turn to other activities during this period so as to diminish the psychological load caused by the response delay. This paper aims to experimentally examine this effect in detai1. On the model VDT task in which response time was set at 30 seconds on the average, performance and psychological load were compared between the subject's conditions of only watching the CRT vaguely and turning to reading easy document. The results show that the psychological load is remarkably decreased when subjects turn to other activities. Based on the results, the psychological effect of operator's turning to other activities during rather long response time is proved.

In this paper, we deal with a Distribution/Location Problem of Multi-commodity (MDLP), in which the optimal locations of Distribution Centers and the transportation routes of trucks are determined. We formulate this problem as an integer programming, including integer variables that express the number of trucks. By relaxing those integer variables to real ones, we get a relaxation problem of the MDLP-a Simple Plant Location Problem (SPLP). Then making use of a procedure of the SPLP, we propose an approximate procedure for the MDLP and a branch and bound procedure to decide an optimal solution of the MDLP. Finally some numerical comparisons between the two procedures are shown.
