- 1. Robust scheduling in changing environments.
- 2. Production system robustness, flexibility, and buffering.
- 3. Construction of design theory for production management systems based on characteristic analysis of material requirements planning and lean production systems.
- 1. Research on production scheduling methods has often assumed unchanging production environments, with little consideration given to changing environments, even though on-site production environments change by the hour if not by the minute. There is growing recognition that such environments must be considered and this has resulted in a burgeoning new field of research, as seen from the rapidly growing number of citations of Ref. 1. We are focusing on expanding and building on the foundation established by Ref. 1, as seen by the advances in Refs. 2 and 3 concerning process times.
- 2. The late Prof. Hitoshi Tsubone of Tokyo Metropolitan Institute of Technology worked vigorously to build on the foundation established in Ref. 4 concerning flexibility. Subsequently, we have turned to quantitative elucidation of the interrelationship of flexibility with robustness and buffering, an area that has been neglected. Recently, we have focused on the relation between flexibility and buffering in mixed-model assembly lines, and on increasing flexibility by dividing each line into segments using buffer stocks and changing the input sequence of the preceding and succeeding segments. The initial results are described in Ref. 5.
- 3. We are modeling current production management systems and analyzing the relationships between the factors involved to determine the system parameters objectively. The ultimate aim of these studies is to enable engineering-based design of production management systems that match their environments. Existing theories on the allocation of push and pull modes tacitly assume unlimited stock life; however, research is underway on mode allocation with finite stock life for both modes.
