Recently, Ohta et al, reported that an optimal scheduling model for drivers in bus transit systems is formulated as a 0-1 goal programming model. In this paper we propose an efficient algorithm for solving the optimal scheduling problem for bus drivers. This algorithm has an effect on the computer storage required and the computational time. The algorithm proposed here and the usual method are quantitatively evaluated using a numerical example for the optimal scheduling model. In the software package developed here, we adapt the data entry system designed using the BNF notation.

It is currently popular to classify the production control system for multi-stage manufacturing processes into a push-type system and a pull-type one. While the behaviors of inventories in the push-type system which utilizes the information of future demands are affected by a forecast error, those of pull-type systems are affected by fluctuation of demand. In this paper we deal with a Hybrid Push/Pull Production Control System, operated periodically, which joins the benefits of both systems, Theoretical arguments on the advantage of this system are discussed and a numerical study is shown to give an insight into the system's performance.

Just-In-Time production is to keep the Kanban system. When production managers implement and operate successfully the system in the multi-line, multi-stage prodution setting, it is very important to determine the number of kanbans in a deterministic kanban system in consideration of the relevant factors as well as the cost. Concretely, we discuss about the following factors in the kanban system and provide a model formulating the mixed integer goal programming : demand, stock on hand in process, inventory cost and labor cost, vendor's suppling capacity, work load. Finally, we analyze several numerical examples in order to test the model and attempt to expand the model in a general case.

As one of business strategies, corporations have begun to request mediators such as banks to carry out M&A tasks. In such a situation, a support system for M&A is needed. The purpose of this paper is to analyze the tasks of M&A management and to develop a support system for them. This system consists of four main sub-systems ; 1) determining the purpose of M&A, 2) selecting corporations that satisfy these purposes, 3) evaluating corporations purchase prices, 4) securing funding. The design for this support system is based upon the need for 1) using various approaches to determine the price of M&A, 2) providing the user with various kinds of information needed to select and evaluate the companies, and 3) providing the user with interface functions for easy use.

In this paper, a dynamic software reliability prediction analysis is presented using reliability petri net models. Combinatorial type models (such as software fault tree, reliability block diagram, module graph and directed acyclic graph) are not suitable for dynamic reliability predictions of the embedded, concurrent, parallel and fault tolerant software. For this problem, the author proposes a Reliability Petri Net (RPN) which is an expansion of Condition/Event Net. Using the RPN models, we can predict dynamic software reliability and performance in the modeling phase of a software.

This paper deals with a lot-scheduling problem of multiple items processed on a machine under JIT environment where all the parts have a common due date. The performance measure used is the actual flow times providing with both receiving-raw-material-just-in-time and shipping-finished-part-just-in-time. The problem is divided into two subproblems, namely, the subproblems of lot sizing and scheduling the resulting lots. The solution method for the subproblem of lot sizing and that for the subproblem of scheduling could separately be optimal. However, since each subproblem is not independent of the other, the proposed method solving the problem of lot-scheduling is to be considered a heuristic method.

This paper deals with the problem of designing a flexible production system by the simultaneous introduction of component part commonality and production planning procedure. This paper supports the choice of a production planning policy for a two-stage process, analyzing the relationship between the component part commonality and production planning procedure in terms of the manufacturing performance. The simulation results have quantitatively clarified that the component part commonality can decrease the ratio of setup time and the buffer inventory level required.

This study considers a system where the minimum number of work stations are formed in a multimodel assembly line by robot and the optimum number of work station is determined from the economical criterion. The system with the minimum number of work stations is suggested by intensifying several work stations when the practical line exceeds the theoretical by longest line. An economical formula that presents the optimum number of work stations is suggested to determine whether the robots used in this system are profitable.
