| Research Abstract |
This study focuses on schedulers whose primal task is to decide the daily production plan. First we visited schedulers of ten manufacturing companies located in Chugoku region and asked the following questions; production planning system adopted, planning hierarchy and procedures, evaluation measure of schedule, degree of discrepancy between daily plans and their results, factors that cause changes, and requests to the academic research. The interview research revealed that the collaborative production planning had been adopted in many companies. The word collaborative means that schedulers made the production plan by using the production information system and also by talking with staffs of sales department and shop floor workers and foreman. Suggestions from the workers or foreman are often useful to improve the production plan. Detailed production schedule was often generated by foreman of the shop floor because such a decision needs a deep knowledge of process requirements and a full understanding of current shop floor conditions. The schedulers generally repeat the following three tasks several times; grasp the current condition, make or revise the plan, and evaluate the plan. Typical information needed is combined with the above iterative actions, and considered as a basic thinking pattern of the schedulers. The interview research also revealed that the importance of the schedulers was not evaluated correctly. Under a hypothetical manufacturing environment, a simulation model of the schedulers was proposed based on system dynamics. The simulation results demonstrated the importance of the collaborative planning activities of the schedulers quantitatively.
