Concerning the vesual inspection work at a conveyor belt, the following were verified through experiments.(1) The usefulness of a paced work experiment : a paced work experiment was proved to be a useful means of clarifying the structural features of each work, which can not be grasped under normal work speed. A "paced work experiment"means an experiment in which the sped of feeding products is controlled at various paces.(2) Comparison of structure beween the two feeding systems - continuous system and tact system : when the structural differences between these systems were clarified, tact system was proved to be superior.

In the design processes of effective work groups we define the worker, task and supervisor as the basic structural elements of work groups, and examine various situations of attributes and effectiveness of work group.It has been ascertained through our researches that group effectiveness is influenced by the relations between these structural elements. This paper suggests the procedures to analyze the relations between these elements and illustrates some criteria to evaluate the effective relations among workers and tasks toward improving job satisfaction and work performance.

Using the principal component and principal cluster, workers are mostly classified into two groups in every worker's desire pattern. These two groups mutually have quite different and interesting characters from the viewpoint of workers' motivation. We abstract some key factors affecting workers' desires by test of uniformity on the design factor in each group. Consequently, we clarify the influence of wordshop factors on the desire patterns with "to overcome various flustration in one's job" and "to work optimistically without being concerned with company objectives."

In a job shop, to minimize idle time of the shop and to reduce waiting time of jobs, having backlog to create a buffer against idle time and temporarily increasing its production capacity (for example overtime) are recommended. In this paper, distribution of backlog ot the end of the period and idle time are studied using numerical calculations when such a buffer is created and such a production capacity is temporarily increased.Some characteristics of this control is shown and procedures of deciding parameters to establish a more efficient control over the shop are shown.

Merit rating is the main source of information in personnel managenent. For this information to be used effectively, appropriate weights must be assigned to the elements of merit rating. In this paper we propose a new method for determining the weights, using "the paired comparison method" and "the minimum stress standards."Then we use it to tentatively determine the weights, utilizing the data collected in a certain company. The result is being compared with those acquired by the conventional "council system"of "rating madel"methods. The validity of this method is being examined through the use of coefficient of correlation.

In order to suppress the variances of the production and inventory levels of the multi-stage production inventory system, this paper proposes two types of produciton ordering systems which are classified by the feedback method of the sensored informations, and analyzes the infiuences of the autocorrelation coefficient of demand and the loading ratio upon the amplifications of the production and inventory levels. As a result, it was clear that an effective production ordering system was chaned according to the levels of the autocorrelation coefficient of demand and the loading ratio.

In the last note of this lecture multivariate analyses based on fuzzy theory, especially fuzzy quantification theory and fuzzy hierarchical clustering method are explained. In preoparation for discussing these methods the concepts and definitions of fuzzy events and fuzzy relation are clarified. An analysis of purchasing factors and a clutiering of various drinks are exemplified in the explanations of the fuzzy quantification theory and the fuzzy hierarchical clustering, respectively. At the close of the lecture, brief comments are given on the applicotion of the fuzzy theory to real problems and its future view.
