Indifference zone formulation has played a predominant role in the area of statistical selection and ranking problems. In the application of the procedure to practical problems, the researcher has to specify the two constants δ^* (indifference constant) and P^* in advance of experiment. It may not be simple to specify the value of δ^* for most applications. This paper considers the problem of determining the value of δ^* based on cost function. The solutions for δ^* and sample size which minimize the cost function are obtained under the restriction that the best one is to be selected with a specified probability P^*. The procedure is applied to the selection of visual inspector for car body painting.

This study considers the effects of visual search tasks with hard copy and VDT on visual function and cerebral function. In particular to clarify the influence on short-term memory, several measurement tasks pertaining to memory and judgement were employed before, between and after the two sessions of visual search tasks, and their processing times were measured through an eye-mark recorder. They implied that VDT task effects more load to cerebral function as well as visual function and that its effects do not occur at the stage of encoding but at the thereafter processing stage in short-term memory.

The technique of sampling inspection with protection small location parameter is proposed for two parameters exponential law. The inspection is carried out by comparing the minimum value of the sample to the acceptance value. Each case is disscused where the scale parameter is known or unknown about the population.If the scale parameter is unknown, use of estimated value and sequential sampling make the inspections possible.This technique is experimented by Monte-Carlo method and the effects of confidence coefficient of the estimated scale parameter on percentage of acceptance is discussed. By programming the technique on the portable computer, the inspection is accomplished easily.

This study extends the customary dynamic lot sizing model to the one that includes as expediting cost due to the delay of outstanding order and allows to offset the order release date in advance, instead, in order to avoid incurring the cost. We first consider the single-stage case and propose a quasi-WW algorithm corresponding to the Wagner-Whitin algorithm, and second extend the result to multi-stage cases and propose their optimal solutions by introducing such concept as a psuedo-nusted schedule.

This paper suggests a classification method for predicting the probability of goal attainment in designing work groups and then proves the validity of the new method. Triplets of structural elements in work groups are classified by the method. Each triplet is formed from a worker and its task and supervisor. A set of similar types of the triplets is used for modeling conditional probabilities from the viewpoint of the so-called AIC minimization.The probability where each triplet will attain a design goal is predicted as the conditional probability of goal attainment given the similar type to which each one belongs.

In the conventional regression analysis, the method of least squares is usually employed. However, the least square estimator may be spoiled by some grossly outlying data. While the robust estimator is highly outlier resistant. The regression problem which uses the robust estimator is called the robust regression. Though the observed value should be sharp, sometimes it may happen that our data are not so precise enogh. In such cases the data should be regarded as fuzzy data. Two methods of the robust regression of fuzzy data proposed in this paper rely on the fuzzy mathematical programming. The quadratic programming is used to first method and the linear programming is used to the second method. Since the fuzzy mathematical programming is adopted to these regression problems, the knowledge of expetrts can be expressed as the constraints.
