The probabilistic combinatorial optimization problem (PCOP) is a generic name of a specific family of combinatorial optimization problems whose common characteristic is the explicit inclusion of the probabilistic elements in the problem definitions. The main contribution of the paper is to introduce polyhedral combinatorics to the area of PCOPs. Some concepts of polyhedral theory are generalized to the PCOPs. We also prove some theorems which give the general methodology for deriving the valid inequalities. Based on these basic results we can derive lower bounds for the probabilistic variations of several well-known and practically important combinatorial optimization problems.

For a product which has multiple quality characteristics, the performance of multiple 100% inspections with type I and type II inspection errors is considered. In this inspection procedure, one of the quality characteristics of a product is inspected at the first stage, and any quality characteristic of the accepted product is subject to inspection at next stage. To characterize the performance of inspections, the Average Outgoing Quality and the proportions of accepted units to lot size are evaluated. To determine the optimum inspecting order of quality characteristics, cost model is introduced.

The multi-vehicle routing problem is to determine the optimal routes for all vehicles through a set of locations subject to vehicle capacity constraints and other restrictions. The objective is for the last vehicle to return to the depot as fast as possible. The problem is formulated as an integer programming problem with two types of variables. One is indicated by a sequence of locations, and the other by the set of the first locations arrived at on their routes. The best sequence of the former variables can be obtained by using genetic algorithms, and the latter can be optimized by applying the branch-and-bound technique.

In this paper we show a theoretical criterion of choice between a FSOS (fixed-size ordering system) and a FIOS (fixed-interval ordering system), and then propose a mixed ordering policy which is incorporated in the elements of both types of ordering systems. The mixed policy designed here combines the feed-feedback mechanism of a FIOS with the on-off (reorder point) mechanism of a FSOS. More specifically, the mixed policy orders a required quantity by taking into account the forecast demand and term-end inventory whenever the current inventory breaks a reorder point forecast at each period. We will prove the advantages of this mixed system by comparing between the performance of the two systems.

In a two-level decentralized system (a corporation) consisting of a headquarters and divisions, it is required to make its decision considering not only competitions with others but also the coexistence with the social environment to persuit the overall development of the corporation. This paper develops a "single-objective, two-level decentralized system" into a "multiobjective-headquarters, two-level decentralized system" and formulates a mathematical model for the extended system. A method for generating all the nondominated solutions is proposed by exploiting the properties of a set of feasible extreme points in the mathematical model. A numerical example is demonstrated to show the effectiveness of the proposed method.

The use of linguistic variables and fuzzy algorithms provides an effective means of describing the behavior of systems as linguistic rules, i. e., fuzzy if-then rules. In this paper, we propose a method for generating fuzzy if-then rules from numerical data. We also suggest a method for translating real numbers in the consequent of fuzzy if-then rules into fuzzy sets with linguistic labels. Then we illustrate our approach by computer simulations on numerical examples. In order to demonstrate the effectiveness of our approach, we apply it to the sensory test data on rice taste.

In the (x^^-, s) simultaneous control chart, the behavior of a pair of sample mean and standard deviation expressed as a point (x^^-, s) is monitored on a rectangular co-ordinate graph which arranges x^^--control chart and s-control chart. Ohsumi proposed a circular control limit which refers to x^^-- and s-control chart's upper and lower limits. However, the user of the (x^^-, s) simultaneous control chart can not design the control limit assuring the specified level of significance. With respect to this problem, we enable to estimate the level of significance of the (x^^-, s) simultaneous control chart's circular control limits by using the distribution function Grad and Solomon gave. Furthermore, in this paper, we propose a new design procedure for the control limits of the (x^^-, s) simultaneous control chart from the viewpoint of specifying the level of significance.

This paper describes the principle of a new dynamic simulation method for the system consisting of the impact-relations and the functional-relations, named GSIM (General SIMulation) method. It is known that the two dynamic simulations are available for analyzing the dynamics of social system, etc. One is System Dynamics (1961,W.Forrester) that can be applied to the system consisting of the functional-relations only, and the other is KSIM (1971,J.Kane) that can be applied to the system consisting of the impact-relations only. But they are inappropriate to the present research on the complex system, because they have 3 problems as follows : 1) Can not be used for the system with a mixture of the impact-relations and the functional-relations ; 2) Impossibility of succeeding easily to the knowledge of the previous mathematical models ; 3) The impossibility of its app1ication to the most advanced system engineering related researches. In this paper, it is proposed the GSIM method that can improve these 3 problems.

In this paper, we suggest two types of learnings in organizations. One is the learning to become an expert in the particular job, and the other is a wide learning to prevent the local optimization. We present a conceptual model which describes these learnings. The performances of the learnings are evaluated by the model in simple numerical instances. As a result, we have become able to analyze in time series the performances of these learnings in organizations and present a view point about the performances of these learnings.

This paper deals with the design of safety stock level for satisfying the required service rate of a production inventory system with production capacity constraint. After reviewing the previous literatures, this paper proposes a method to design the safety stock level. The proposed method based on the secant method for solving non-linear equations utilizes the simulation for estimating a service rate and the numerical analysis for calculating quantiles. Examples show the validity of the proposed method, and the influence of the service rate and production capacity upon the safety stock level is analyzed with the proposed method.

This paper deals with the two-objective design of the separated-functional FMS to minimize the total equipment cost and to reduce the number of pallets, provided that the number of machining centers and the limit of the number of pallets, which were fixed in the previous paper, are not given in advance. The properties of the objective functions are analysed according to the closed queueing network theory. An efficient algorithm is proposed for generating all nondominated solutions to this model. Applying the algorithm to a numerical example illustrates the procedure for selecting a preferred solution among the derived nondominated solutions.

In the previous paper, it is shown that the scheduling model for the Multi-Stage Process can be reduced to the One-Machine problem of allotting jobs between the earliest and latest end times for each job. This paper proposes the reducing method of the scheduling model size, in which the 0-1 variables which represent the job sequence are specified by the earliest and latest end times. By use of this method before solving the problem, it is shown that a practical scale problem can be efficiently reduced to a smaller scale problem. The efficiency and property of the reducing method are also shown through the numerical illustrations.
