本研究では,加工フロアにおいて手動工作機械を用いて加工作業を行う作業者の勤務スケジューリングについて検討する.本研究の特徴として,作業者の休日に対する希望を考慮してスケジューリングを行う.そのため,作業者が希望する休日と実際の休日が一致する日数の最大化を目的関数,制約条件を労働基準法で定められた勤務日数および要求生産量を満たすための各日の作業者数とし,整数計画問題として勤務スケジュールを作成する.

Autonomous Distributed Manufacturing Systems (ADMS) have been proposed to realize flexible control structures of manufacturing systems. In the previous researches, a real-time scheduling method based on utility values has been proposed and appliedto the ADMS. In the proposed method, all the job agents and the resource agents evaluate the utility values for the cases where the agent selects the individual candidate agents for the next machining operations. Multi-agent reinforcement learning is newly proposed and implemented to the job agents and resource agents, in order to improve their coordination processes. In the reinforcement learning method, an agent must be able to sense the status of the environment to some extent and must be able to takeactions that affect the status. The agent also must have a goal or goals relating to the status of the environment. The status, the action and the reward are defined for the individual job agents and the resource agents to evaluate the suitable utility values based on the status of the ADMS.

In design and planning of manufacturing systems, a wide variety of models representing the manufacturing systems are required for simulation and verification from various viewpoints. These models are concurrently developed and applied to various application fields, therefore, a computerized support system is needed for concurrent development and consistency management of the various manufacturing system models. The objective of the research is to develop an object-oriented model repository aiming at supporting concurrent development and consistency management of the various manufacturing system models for production planning. Contents and structures of manufacturing system models are discussed from the viewpoint of the concurrent and hierarchical production planning problems. Model components and their relations to be stored in the model repository are proposed. A prototype of a model repository is developed and applied to the production planning problems.
