Local search heuristic for single machine scheduling with batching to minimize total weighted completion time

Jobs are partitioned into families, and a set-up time is necessary when there is a switch in processing jobs from one family to jobs of another family. The objective is to minimize the total weighted completion time. Four alternative neighbourhood search methods are developed: multi-start descent, simulated annealing, threshold accepting and tabu search. The performance of these heuristics is evaluated on a large set of test problems, and the results are also compared with those obtained by a genetic algorithm. The tabu search method generates high quality schedules relative to the other methods at modest computational expense Next title: Local search heuristics for single machine scheduling with batching to minimize the number of late jobs (RV of 95/28/TM) - Crauwels, H.

Local search heuristics are developed for a problem of scheduling jobs on a single machine. Jobs are partitioned into families, and a set-up time is necessary when there is a switch in processing jobs from one family to jobs of another family. The objective is to minimize the total weighted completion time. Four alternative neighbourhood search methods are developed: multi-start descent, simulated annealing, threshold accepting and tabu search. The performance of these heuristics is evaluated on a large set of test problems, and the results are also compared with those obtained by a genetic algorithm. The tabu search method generates high quality schedules relative to the other methods at modest computational expense
