非線形計画問題のマルチエージェント形最適化手法の一つに市場指向プログラミングがある.しかし現実問題への適用を考えた際,決定変数に整数値を含む問題が多数存在し,従来の市場指向プログラミングの適用は困難であった.そこで本研究では,市場指向プログラミングにて整数値が扱えるように拡張することで混合整数計画問題へ適用を可能とする手法を提案し,その有効性を検証する.

In this study, scheduling method using a combination of auction-type real-time scheduling and simulation is proposed in order to automate the scheduling in dynamically changing manufacturing environment. The control mechanism which is essential for executing real-time scheduling and simulation simultaneously is developed and implemented. The auction algorithm for the real-time scheduling which improves the delay of delivery date and amount of setup time at the same time is proposed. Also the method of simulation during the real-time scheduling which can predict the changing situation of the shop and automatically take countermeasures by adjusting the scheduling precondition is proposed and its effectiveness is confirmed by computational experiments. With these methods, prototype system is developed and tested under the condition of actual machining line. As a result, it is clarified that the proposed system has the ability to respond flexibly to dynamically changing manufacturing situation.

In real manufacturing system, changes take place in the shop floor frequently. When a manufacturing simulation system is developed and used for the daily operational planning and evaluation, the simulation model must be in a good correspondence with the real manufacturing system. Therefore, how to reflect various changes in the manufacturing system to the simulation model and thus keep the model updated become important issues to be answered. In this study, towards automated updating, simulation-modelling formalism for manufacturing system is proposed. This formalism makes use of change suppression technique as well as late binding and polymorphism in object-oriented technology to make the simulation model uniform, consistent and keep unchanging even for various changes so as to achieve the automated updating. A generic framework capable to deal with the automated updating for manufacturing system simulation is constructed. The proposed modelling formalism is proved to be effective through experimental simulation system construction.

Under the volatile economic situation in recent years, manufacturers need to have a high level of flexibility to manage a wide variety of products in varying quantities within a short delivery lead time. But in dynamically changing manufacturing environment, it is quite difficult to optimize interdivisional scheduling which reduces total manufacturing cost of all divisions such as raw material procurement, machining, assembling and shipping following fluctuations in demand. To solve this problem, we propose a new interdivisional scheduling method which decomposes the whole problem into process-dependent problems using inter-process lead time and cooperates between processes by applying Lagrangian decomposition coordination method. Additionally we designed the method which can adjust inter-process lead time automatically in order to respond to the changing demand of each item. Then we examine the effectiveness of this method by numerical experiments.
