Abstract
This study took examined multi-stage flow-shop scheduling method of machine processes based on the independent setup between each manufacturing process. The conventional Branch and Bound scheduling method was applied and improved upon to suit this method, with the following results. 1) When applying this model to the conventional Branch and Bound method, an unreliable Low-Bound (LB) value results since idle time for unscheduled products is not included. Improvements to LB value, then, raises precision rates and leads to greater calculation efficiency. 2) Practical implementation of the proposed model also revealed an economically efficient number of required setup workers.
