유연흐름시스템에서 fuzzy목표 개념을 이용한 다목표 뱃칭모형 = A BATCHING MODEL USING FUZZY GOAL CONCEPTS IN FLEXIBLE FLOW SYSTEMS

다국어 초록 (Multilingual Abstract)

In this study, a batching model for Flexible Flow Systems(FFS) was proposed. For batching part orders, the multiple-goal model was designed using fuzzy goal concepts and its usefulnesses was analyzed. The multiple goals included minimizing the number of batches, balancing workloads between machine groups, and meeting the due dates of part orders. The proposed model was compared with other models with respect to minimizing the number of batches. Because the supreme goal of maximizing the production rate in FMS production planning can be converted into the surrogate goal of minimizing the make-span, and beacause minimizing the number of batches means minimizing the set-up times, minimizing the set-up times makes the make-span shorter if all other conditions are held constant.
