Most seasonal goods are not allowed any leftover inventory at the end of the season. Therefore, once these seasonal goods are produced, they should be entirely sold before the end of the season. With this in mind, theoretical equations which detemine the optimal shipping quantities for each planned period and which minimize the expected quanitity of stockout and excessiveness under the planned shipping abilities were constructed by using the principle of optimality. Experiments were then performed to quanititarively detemine the aveailability of this system.

This paper discusses a production plan for potted flowers grown under glass. Before the production, the producer decides the kinds of potted flowers that are recognized to be able to fulfill the long-term production requirements. Epiphyllum russellianum Hook is selected as a sub-item from those currently grown under glass and its production plan is discussed. This potted flower produces plural products by growing it continuously for several yeaes. Cuttings are supplied from the products themselves of which shipment is carried over to the following year. After pigeonholing the data for this potted flower in preparation for formulating the problem, we show a steady policy that maximizes the yearly income under the normal conditions in a graph relative to price.

This paper considers the structure of consumers' expectations on product quality. From a survey of three durable goods, we have obtained eight expectation factors as the viewpoints in market place which are almost common to the three products, and showed that the structural difference among these products was the weights on the factors. By using these factors we verified the relations of quality expectations with the consumer's attributes and product quality designed by each producer. Further the problems of measurement and scaling in the survey are also considered.

This paper analyses some statistical characteristics of the two-stage chain sampling inspection plans by use of GERT (Graphical Evalution and Review Technuque)and offers the economical aspect of these plans. GERT simulation (GERTS) is also applied to analyze the complicated sampling inspection plans. This work may be of assistance in designing the most economical plan which minimizes the total average cost for a given lot tolerance percent defective (LTPD) and consumer's risk (β).

Learning effects in a work usually appear in multi-factors. Time consumed in a work, exactness of working, etc. are the examples of multi-factors. When each of multi-factors of learning is observed at the same time, some abnomal phenomena are often found in the middle stage of learning process. In this paper, such abnomal phenomena are discussed and the relations between multi-factors themselves are made clear through ergonomical expriments.

The autcome of alternative manpower policies on organizational job performance, ability and work motivation of members would be affected by various elements on individuals, groups, and an prganization. In this paper, to discuss the meanings ans effects of these elements from the point of view of systems approach, we carried out sensitivity analysis by using a computer simulation model. As a means of sensitivity analysis, the design of experiment was adopted in order to measure main effects and interaction effects. As the result, a guide of the measurement in the aspects of learning, value orientation on work motivation, skill levels required by positions, skill levels possessed by individuals, and cooperation relations in work groups was obtained in relation to the propensity for fuzzy structure in organizations.

This paper presents several heuristic approaches to the multiple objective programming problems with 0-1 variables. We extend the Effcient Gradient Method and the Space Method to the multiobjective case. Each composite scoring function of the goal attainments of project which is used in the method, is reflected in the typical type of utility function. Therefore, these methods are mutually complemented. Finally we discuss the prectical use of these approaches.

The management decision problems are often formulated as the multiobjective programming problems with 0-1 variables.This paper presents two interactive and heuristic methods for the problems. In these methods, the decision-maker merely selects his preferred (or repugnant) points from a succession of small sets of candidate solutions. Using techniques for constacting and shifting the cinvex cone generated by the gradients of the multiple objectives, each method employs an algorithm for vector-maximum problem to focus on the decision-maker's most satisfying solution. Further, the implicit enumeration technique is used for finding candidate solutions. Some numerical experiments are designed to investigate the properties of methods.

In the Part I the author described mainly the theoretical side of the PARM (Principal Axes Rotation Method). Following it, he this time compares his new method (PARM) with one of the comventional methods (Choleski Discomposition Method), by the Monte Carlo Simulation. And he concludes the former is a little better than the latter in the 1st, 2nd, 3rd and 4th moments respectively. In connection with these, he writes some notes about his computer (IBM-370-138) and his application programs (SSP-GAUSS and JACOBI).

This paper presents the prectical formulation and solution for the Multi-Goal Programming Problems with 0-1 variables which often apper in project-selection problems. In practice, objective functions of these problems are often formulated into linear fractional functions as well as linear functions. The algorithm is similar to "implicit enumeration techinque" in 0-1 Integer Programming. A deviation-balancing approach based on a goal-vector concept is assorted in the algorithm. Also, a numerical example is provided to illustrate the total procedure that is described in this paper. Finally, several future extensions of the algorithm are discussed.
