Japanese autonomous management system, such as QC circles, is drawing much attention from abroad, as a basis for high productivity and high product quality in Japanese industries. The background of its succes is two-fold : first, it conforms well with the characteirstic Japanese social climate, and secondly, Japanese workmen are generally well trained in the basic philosophy and fundamental technologies of industrial engineering, which originated from Taylor's scientific management. In this paper, after reviewing the position of the scientific management in the history of management and the characteristics of Japanese social climate, the author will discusses some of the problems concerning some new ways of management baesd upon the autonomous management principle.

An analystical job assessment method was developed to discover more jobs for the physiaclly handicapped under the research project 1977-1980 subsidized by the Department of Labour, Kanagawa Prefectural Government. The idea of the method is to decide the required physical functions for the handicapped to perform jobs. They are divided into 30 physical functions in total including the upper and lower limbs, trunk, eyes, ears and mouth. The function analysis is carried out for sequential job elements which compose each job. Thus, the physical requirements for each job in factories as well as in offices are recorded, and the possibility of replacing able-bodied workers with deformed persons is assessed on each job. The job assessment is carried out on direct observation at workshop using a newly developed "analytical job assessment sheet." Further the procedure to modify job fittings for the handicapped was suggested in the method. 604 jobs have been found to be replaceable within Kanagawa Prefecture as a result of a supplementary investigation using this mehtod, and at the same time, the practical effectiveness of this method has been provided.

The study of body proportions, the study of beauty of human body, has continued since the times of old Greece. Such a study was, however, partial to theoretical research, that is a study for study's sake. It is rather regrettable that it was not available in the real life of the general public, but sometimes seemed to be only an amusement for the nobility. Accordingly, based on the ancient studies and general women's own consciousness, we have established an ideal body proportion. We name it "the beautiful proportion" and propose it as a realizable beauty standard which is applicable to women of all ages, in their twenties, thirties and forties. We have been striving for a method to aid every woman's body approach to "the beautiful proportion"; this is the sensible way of merchandising, we believe.

This papaer deals with a newly designed order entry system. The system is expected to meet the diversification of market demands and the prompt supply of commodities. Several experiments show the effectiveness of the proposal system in terms of the size of inventory decrease, the marginal income increase and the improvement of service ratio.

This paper verifies assumptions of the theory which is described in Part I-(i) the total core operation time is in proportion to H_1N^α (H_1 : the core operation time of one person, N : personnel number, α : coefficient of learning) in case of star type and net type, (ii) the total adjustment operation time is in proportion to N-1 in case of star type, and to N(N-1)/2 in case of net type. The results from experiments on 65 children of an elementary school show that the propriety of assumptions of (i), (ii) is clear.

The systematization of energy-cionsumers is needed to solve the problem of efficient usage of energy. For this purpose, this paper presents a method to desgn energy-flow-systems. The informaiton about the kind, scale, and flow-system of combination of energy-consumers to minimize the energy cost is obtaiend through this method. The steps of this study are as follows; 1) The problem of designing the system is formulated. 2) A procedure to decide the combination of energy-consumers and their scale is presented. 3) The above-described procedure is applied to a simplified problem.

A mathematical model of a resource allocation problem in a two-level decentralized firm is constructed, based on a decision-making structure of a system that consists of a headquarter and several divisions. A solution algorithm to this problem is proposed, in such a wasy as the resource allocaion problem of the headquarter is replaced by an alternative plan-selecting problem. The branch-and-bound algorithm is employed to solve this selecting problem. The characteristics of the system proposed are examined by numerical examples.

This paper shows a new mehtod which estiamtes numerically the work performance of workers. This method is not an ordinary analytic way which uses the mean value or the standard deviation but one where some results of work are estimated numerically by the work achievement Q. As an example of practical applications we show the performance of some type-pickers.

A model for the optimum decision of the capacity and location of plants was constructed on conditon that the probability distribution of demands at consuming districts is known; then, an optimizing algorithm for solving the problem was developed. In the process of the model construction, it was assumed that construction cost and production cost are nonlinear, and the construction capacity for plant at each candidate point is limited. The problem was formulated as an optimization problem having two criteria, expected profit and expected losss, and a practical solution algorithm was developed. The effectiveness of the algorithm developed was proven by solving sample numerical examples.

It is necessary for the development of a product and its sales planning ot estimate the latent structure in consumer behaviors by analyzing the characteristic attributes which cause consumers to purchase it or not. In this paper, Fuzzy Quantification Theory Type II is employed to analyze the consumer behaviors. Fuzzy Quantification Theory Type II is useful for analyzing consumer's recognition of these attributes, in which data of vague qualities are dealed as fuzzy sets. The consumer behavior in purchsing cars is analyzed by our method to prove the goodness of our approach.
