Abstract: Aiming at the urgent attention of single machine system on production scheduling and facility preventive maintenance in group production,an integrated optimization model was proposed to meet the requirements of product processing and equipment maintenance.In this model,the learning and forgetting effect on producing identical or similar parts was considered,and the deterioration effect by considering facility operation was proposed to perform the perfect preventive maintenance.When the machine failed due to unexpected accident,minimal repair was performed.To meet dual requirements of production scheduling and equipment preventive maintenance,the multiple objectives of this model such as minimum makespan and maintenance costs were proposed,and a genetic algorithm was developed to solve this model.The results of example analysis showed the feasibility and effectiveness of the proposed model.

Key words: group production, learning and forgetting effects, deterioration effect, production scheduling, preventive maintenance
