"Modal Shift" is advocated to shift the transport means from the truck to the railroad and/or the ship in recent years. The main means of the present domestic transport is the truck in Japan But we expect that the physical distribution only by the truck will become more difficult in the near future because of the increase in the driver's salary, the traffic congestion and the environmental problem by exhaust gas from trucks. Especially, in the environmental problem by exhaust gas, we expect that the environment lax will be introduced into Japan like Europe to regulate the amount of discharge of carbon dioxide which causes the global warming.
In this research,we shall optimize the physical distribution and the facility location based on the modal shift for environment conservation with the environment tax and we also propose the way of employing them to domestic transport.

The time - based goal chasing method (TBGC) has been proposed to keep the consumption rate of each part constant in consideration of the different assembly time. The good point of TBGC is able to consider the influence of idle time and line stop time in the total assembly time. However, TBGC has been only applied to assembly line without line stop. In this paper, we apply TBGC to assembly line with line stops. Therefore, we formulate work situations on assembly line.

記述言語：英語出版者・発行元：Elsevier Science B.V.

In mixed-model assembly scheduling with a single workstation, there is a new sequencing method [time-based goal chasing method (TBGC)] in consideration of the different assembly times between jobs. In this paper, we propose a new objective function in expanding the TBGC. Furthermore, we propose some heuristic methods to minimize the objective function. And through numerical experiments, we show the effectiveness of our proposal.

JIT生産方式における多品種混合の組立ラインにおいて, 部品の平準化は重要な概念であり, この目的を達成するために, 目標追跡法が提案されている.しかし, 各製品の組立時間の違いは考慮されておらず, その違いが各部品の使用量平準化にどのような影響を与えるかについては述べられていない.最近, 各製品の異なる組立時間を考慮したTimeBased Goal Chasing Method(TBGC)が提案された.本研究では, このTBGCの目的関数を拡張し.新たな目的関数の最小化を目指したヒューリスティクな解法を提案する.最後に, 数値実験によって提案法の有効性を明らかにする.

In an FMS, a most complicated problem to be solved may be the scheduling problem which is flexible due to the complexity of the system. FMS needs very high cost for installation, therefore in order to get high efficiency, the most appropriate schedule (in general means the schedule with the minimum cost) should be obtained in the stage of scheduling. In this article an FMS model which is a flow shop-type production system has been engaged. Scheduling method is based on the multiple objectives and the total objective function is to minimize the value of all concerned objectives. Consequently, scheduling algorithm has been composed by applying the backward scheduling with Simulated Annealing (SA) method to realize JIT theory. Finally, numerical example has been conducted to show how the scheduling algorithm works and especially to find the efficiency of the proposed algorithm. According to the numerical example, it is shown that the algorithm works well when it was applied with the concerned FMS system.

In a mixed-model assembly line problem, two objectives has been proposed to decide the product scheduling. One is to minimize the work congestion and the other is keeping the consumption rate of each part. In JIT production system, the latter one is more important, so the goal chasing method (GC) has been prposed to achieve this goal. The difference of assembly time among each product was not cnsidered in any solution algorithms. Recently, the time based goal chasing method (TBGC) has been proposed in which the different assembly time among each product is considered. The good point of TBGC is able to consider the idle time contained in an assembly line. However, TBGC is only applied to a single work station problem. In this paper, TBGC is applied to an assembly line and numerical experiments are presented.

日本経営工学会論文誌 49 ( 5 ) 293 - 302 1998年

近年多くの企業で導入されているジャストインタイム生産方式の下では, 各機械に割り当てられたジョブの実滞留時間の和である総実滞留時間を評価尺度に用いるのが有効であり, 従来から, 総実滞留時間最小化のための研究がなされている.しかし, それらは総実滞留時間だけを評価尺度に用いて作成されたスケジュールで, 最大総加工時間最小化について考慮した最適解法は行われていない.そこで本研究では, 並列機械スケジューリングにおいて, 総実滞留時間を最小化し在庫費用を削減した上で, さらに配賦変動費を削減するようなスケジュールを得るため最大総加工時間最小化を行い, 最適スケジュールを導出する.導出時の最適化アルゴリズムとしては, 最新ノード探索法に基づく分岐限界法を用いる.また, アルゴリズムC言語でプログラム化して, 様々な数値例について数値実験を行い, 計算時間, 探索効率について考察する.

Since the goal chasing method (GC) was first proposed to achieve a constant rate of parts usage goal in a mixed-model assembly scheduling problem, many studies have dealt with this problem. In these studies, however, the difference in assembly time among products which affects the scheduled result was not addressed. Consequently, we proposed a time-based goal chasing method (TBGC) in our previous work. In this paper, we present different definitions of the ideal number of parts used which lead to various evaluation measures, addressed and utilized in previous studies. We propose a new method, TBGC + ML, in which assemble time and usage quantities of parts are both considered evaluation measure. Then, through a number of numerical experiments, we show that our two proposed methods are superior to other methods, and discuss their effectiveness when used under different conditions.

Scheduling in flexible manufacturing systems (FMSs) may require some complex solutions due to the complexity of the system. In practice, the application of just-in-time (JIT) theory to an FMS has become an attractive research topic, and heuristic scheduling rules are practical methods for scheduling job orders in real-time scheduling. This article presents a model of an FMS, and then applies the JIT theory with some heuristic scheduling rules to the backward scheduling method in particular. We carry out the simulation test for seeking the performance measures obtained by each rule. It is shown that some proposed heuristic scheduling rules give better results than the others. It is also shown that in JIT, the backward scheduling method can be a useful tool in helping the user to select the most suitable rules for the system at hand.

In large scale problems of line balancing, a weak point is to spend very effort of calculation when branch and bound method is adopted to solve the result. Therefore, in this paper, they propose the method which can seek the satisfactory result by split the problem into partition. Firstly, problem is divided into several parts, in each part the optimal line balancing is investigated, and then, the results of all parts are jointed together to search the trial solution for the whole part. Lastly, in order to improve the trial solution, line balancing of the union of partitional result is conducted again to search for the satisfactory result. Furthermore, computer is used for the result calculation, the result is compared with the convent ioal method to find the efficiency of this proposed method.

日本機械学会論文集. C編 62 ( 595 ) 1204 - 1209 1996年3月

記述言語：日本語出版者・発行元：一般社団法人日本機械学会

Many previous researches for the Quadratic Assignment Problem (QAP) have been proposed and applied to several layout problems. Tabu Search setting up "tabu list" is one of the effective approaches in these researches. This paper proposes a heuristic method making use of the main features of Tabu Search for QAP. A suboptimal solution should be efficiently obtained by the proposed method which sets up some restricted and forbidden conditions under various situations. The algorithm in this method is coded in C language. Through a numerical example, steps of the algorithm are shown. The effectiveness of obtained solutions is investigated by the computational experiences.

This paper concerns a sheduling problem for parallel machines with different machining efficiencies. Each job has a common due date. Neither tardiness nor early shipping are allowed. Therefore, Jobs completed early must be stored in the shop until the due date. Under these conditions the actual flow time of each job is measured from the starting time until the due date. The performance measure of schedules is the total actual flow time. An analytical procedure leads to some theorems to determine the assignment of jobs to each machine. An optimal algorithm based on these theorems is presented. A numerical example illustrates the procedure of the algorithm.
