Group Technology를 이용한 부품 가공시점의 결정

The objective of this study is to determine a near-optimal time schedule for processing necessary jobs in order to minimize total elapsed time. The fundamental assumptions are that jobs to be processed are classified into several groups and jobs within the same group are processed in succession in the flow-type GT line. A heuristic method by V. A. Petrov is applied to determine the job sequencing. In consideration of production quantity, group sequences and job sequences for each group are determined and the start time of processing for each job is calculated by computer.
