Automatic manufacturing like machining centers can replace the worn cutting tool with a new edge in a short time within the setup time of a workpiece. In this situation no minimum-time speed exists as the usual machining. This paper aims to analyze the optimal machining speeds in this case under three kinds of evaluation criteria-minimum time (or maximum productivity), minimum cost, and maximum profit rate-and to inventigate the relationship between the optimal machining speeds obtained. The efficiency speed range is also examined. An example is demonstrated to explain the analytical results.

Multi-dimensional distance method used in integrating multiple-scale values of alternative is the method using the distance in multi-dimensional space spanned by measurement scales as an integrated value. Using the method, rankings of two alternatives with the value obtained from integration of their multiple interval scale values may be reversed as compared with those of the same two alternatives obtained from integration of their multiple ratio scale values. In case such reversal occurs, integration using distance should not be utilized. Studying the condition under which the reversal does not occur in two dimensional case, the paper presents some fundamental conditions discriminating cases in which distance method is applicable to two alternatives having interval scale values.

Class scheduling is a complex combinatorial optimization problem which involves determining the desirable schedule of lecture times and classes under constraints such as instructors, students and facilities. In designing the time tables, non-systematic, experience-type knowledge plays an important role. Generally, this type of knowledge is extremely difficult for the expert to explain in words. In this paper, the basic architecture of a Class Scheduling Support Expert System for Universities (CSSES/U) is proposed. Where, a simulator which models the expert's work is integrated into the system and the system devoloper uses the simulator to acquire the knowledge of experience. Then, the results and effectiveness of the system are discussed.

On merit rating, it is ideal that all raters give the same scores to a given ratee. However, in fact, raters usually give him various scores, which may be caused by the rating tendencies. So we proposed a rating model for the quantitative analysis of the raters' tendencies in the last paper. In this paper, we make a model relating to the effect of the raters' tendencies, which are obtained in the last paper, and the categories of the rating tendencies (lenient tendency, central tendency and severe tendency). Then we analyze them quantitatively.

The "meaning" of "Ikigai (i.e. Self-Actualization)" consciousness in "work" was studied in enterprise employees. The strengths of "Ikigai" consciousness in "work", " home", "leisure" and "life" were researched through a "rating method." The results were as follows. (1) The "Ikigai" consciousness in "work" meant that in "life" in men employees, but it was not so in women employees. (2) The "Ikigai" consciousness in "home" meant that in "life" in women employees. (3) The "Ikigai" consciousness in "work" was correlated with that in "home". (4) The strength of "Ikigai" consciousness in "life" was determined by the summation of each strength of "Ikigai" consciousness in "work", "home", and "leisure".

LISREL (Linear Structural Relations) Model expresses a relevance within potential structure as a linear relation which implicitly exists in the analyzed world, and the model is one of excellent methods to analyze a complicated factorial structure. However, when the structure has a complex characteristics in which factors relate each other, it is not so easy to make clear the relevance in the structure, because of the ambiguous system structure. In this paper, the concept of fuzzy possibilistic linear regression is introduced to identify the structural relevance by assigning fuzzy number to regression coefficient. We propose a new method which express the fuzzy structure relying on the system coefficient. Finally we apply LISREL model with fuzzy possibilistic linear regression to a structural analysis of Quality Circle activity which is a kind of psychological event.

Product demand is currently in a state of great flux, and most manufacturers are faced with the need to develop economic long-term process capability and capacity plans and short-term (annual) production plans. These plans must be geared toward future possibilities, rather than relying on results of the past. When making such plans, it is necessary to increase reliance on process capability and capacity plans for short-term production plans. An index of economy given as relative annual profit can be used to establish the company's aspiration level in economic process capability and capacity planning. The current paper proposes a theoretical product mix planning model based on the satisfying principle that takes into account factors such as optimal mix planning based on nonlinear programming of any given product and the allowing of room for a search for new products within the process of short-term production planning through the use of this aspiration level. Within this model, new product searches are conducted one by one, and the imputed value concept plays an important role in the process.

Production switching is a realistic, practical approach to the aggregate planning. Primal issue of the production switching is how to get the optimal value of each parameter. Instead of the grid search method, the mixed-integer programming model is proposed based on the assumption of adequate linearization. The proposed model is contrasted with linear decision rule, production switching heuristic, and production switching heuristic based on the adaptive grid search method for the classical paint factory data. The proposed model produces the favorable result and is also able to determine the optimal number of production levels.
