Maintenance on leasing sales strategies for manufacturing/remanufacturing system with increasing failure rate and carbon emission

Abstract

Several literature works have treated the quality question of the new and remanufactured products and its production cost and if the all returned-used products are remanufacturable. In this context, this study treated the case of returned-used products in the lease contract with/without maintenance monitoring option and its influence on the production and maintenance strategies for a manufacturing/remanufacturing system. A new integrated maintenance to production strategy studies the influence of the new and returned-used products according to its quality on the production cost and the degradation level of the manufacturing and remanufacturing units. Firstly, the objective of this study is to determine the economical production plan of manufacturing and remanufacturing units to satisfy the random demands under a given service level and during a finite horizon. Secondly, by considering the influence of the degradation on the failure and emission rates, we determine the optimal preventive maintenance strategy for each production unit, which minimise the total cost of production, maintenance and carbon emission. Numerical results are provided to show the efficiency of the proposed strategies by studying the impact of different parameters of the proposed model.
