The new job design is the design of job based on humanity or human motivation which is not involved in the monotonous work. The method of such design is a new technique in the field of Industrial Engineering, or a technique to imtroduce into job the job attributes, which motivate workers. The objectives of the present paper are to explain job attributes analyzed by a multivariate analysis about the experimental findings of job design, and to suggest an aspect of new industrial engineering technique of job design.

This explanation is intended to give to researchers of industrial management who are concerned about the human problems, especially the industrial engineers interested in the problems of human activity and behavioral science. A commentary is presented in this paper on the circumstances under which behavioral science was developed, changes in the thought of management, studies on behavioral science and the correlations between IE and behavioral science.

A demand forecasting procedure based on ARIMA (p, d, q) model is developed. This procedure consists of 5 steps. They are (1) determination of (p, d, q) (2) estimation of initial parameter values (3) parameter estimation (4) test of the estimated model, and (5) adaptive forecasting. An algorithm based on the modified Gauss-Newton method is proposed, as a parameter estimation method.

A preventive maintenance and replacement policy of machines whose capabilities deteriorate as time elapses is given. The objective of this paper consists in maximization of the pesent value of all futura net profits over a series of equal periodic replacement. The best policy which spans infinitely and finitely planned intervals is analyzed by the discrete maximum principle.

Given numbers (θ_1^*, θ_2^*, …, θ_γ^*, P^*), the smallest sample size is determined so that the probability of a correct selection and ranking is at least as large as P^* when the true (but unknown) ratio of the i-th to the (i+1)-th largest of cell probabilities is greater than or equal to θ_i^*(i=1,2,…, γ). The selection and ranking procedure is illustrated by an example in sensory evaluation.

A successive substitution intefration equation is developed for obtaining estimates of parameters of a finite mixture of multivaroate normal distributions. The equation corresponds to the relative maximum of the likelihood function. It is assumed that the mixture has a known number of constitutional distributions with different parameters. A method of classification of these mixed populations is presented using the results of these estimated parameters. Finally, an experimental example of the classification of preference patterns is given.

In this paper, the errors in the rating factor were classified into biases and random errors, and they were introduced into the structure of the rating factor. The errors were quantified by means of experiments, and thereby made corrections possible systematically with the numerical information obtained. Then the method was condisered to correct rater's errors systematically with the numerical information for the training of a rater.

This paper discusses the design of production planning rule for a type of single-item production-inventory system which depends upon the forecasts. Restrictions of production and inventory capacities which are important factors for determining the amount of production are taken into account in a form of variance. A mathematical model for the system is constructed and analyzed by utilizing differential calculus. The derived planning rule makes it possible to balance the variance of production level with the variance of inventory level.

It is necessary, for solving manpower planning problems, to use the steady state model, which considers manpower development from the long-term viewpoint, and the model which can be optimized for multi-period planning starting from the present state. This paper presents a steady state manpower planning model by using goal programming, in which it is assumed that manpower development is realized by job experiences, and as the results, the period of occupying the position is one of main factors from the viewpoint of learnin. If the present model is used, manpower planning problems can be solved, in which a long-term manpower development is premeditated.

This article describes the characteristics of the mean of, and the variance of, the "service interval" of the clerical unit of the parallel-inependent-type office, which consists of a number of clerical personnel, using I/O methods for the determination of the number of clerical personnel needed. Each number of the clerical personnel in the parallel-independent-type office is capable of doing independently, only particular linds of the "clerical variety". He is not capable of doing all lkinds of the "clerical variety". The "clerical variety" includes the processing of different kinds of forms and records, classified by the differences in the processing methods, work time, and preparing time. The mean of, and the variance of the output interval of the clerical unit are when the input interval is zero. Fromthe results of the study, the mean of the service interval is fixed value even though the input clerical unit volume is increased, also, it decreased proportionally to the multiple of the basic unit of the clerical personnel in the office, when the input-clerical-variety ratio is fixed. Moreover. the coeficient of the deviation of the service interval is a fixed value even though the input clerical volume is increased, and the coefficient increases slightly as the multiple of the basic unit of the clerical personnel in the office is incerased, where the input-clerical-variety ratio is fixed.

In our Works, the electric-power plant (thermal, nuclear and hydro), the industrial plant and the plant on order from the government or public are produced. Seven years ago, the oerfirmance control system was changed to the group incentive system from the wage incentive system. We reviewed this sytem on the following points : (1)Development of the management leadership for improvement of production control, (2)Promotion of the self-controlling production system and the improvement of activities by foreman, (3)Establishment of the performance control system, (4)Improvement in the standard time. And, we obtained 16〜22% up of productivity.
