Production scheduling under the specialized alternative has been found to be a difficult optimization problem if heterogeneous elements are involved. A flow shop sequencing model that incorporates actual constraints encountered in practice is proposed for this difficult case of precast production scheduling. The model is solved using a genetic algorithm (GA). The traditional minimize makespan and the more practical minimize tardiness penalty objective functions are optimized separately, as well as simultaneously using a normalized weighted GA. Comparisons between the GA and classical heuristic rules show that the GA can obtain good schedules for the model, giving a family of solutions that are at least as good as those produced by the use of heuristic rules. © ASCE,.||Source Title:||Journal of Computing in Civil Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/66030||ISSN:||08873801||DOI:||10.1061/(ASCE)0887-3801(2002)16:3(165)|
