摘要
设备制造企业向用户提供产品租赁并同时提供产品相关服务(如设备维修)是服务型制造的重要发展方向之一。在设备租赁交易中,维修服务质量直接影响租赁方的意愿和出租方的利润,但是租赁合同中有关维修服务设计的现有研究却很少考虑服务质量这一关键因素。为解决这一问题,从出租方的角度出发,研究了面向租赁设备全生命周期的维修策略优化问题,建立了利润和维修服务质量最大化的多目标优化模型。在此模型中,采用虚拟年龄模型描述预防性维修对设备状态的影响,引入维修服务质量,考虑了设备价值、租金、维修成本、故障罚金等因素。最后构建了基于NGSA-Ⅱ的模型求解方法,并通过算例验证了租赁设备全生命周期维修策略优化的有效性。
A key direction of service-oriented manufacturing is leasing products and providing relevant services(e.g.equipment maintenance)by original equipment manufacturers.In equipment leasing transactions,maintenance service quality directly affects the lessee's leasing intention and the lessor's profit.But the existing research on the design of maintenance service in the lease contract rarely takes into account the service quality as a key factor.Thus,from the perspective of the lessor,a multi-objective optimization model was proposed to maximize the profit and maintenance service quality in the leased equipment life cycle.Introducing maintenance service quality,the proposed model used virtual age to describe the impact of preventive maintenance on the condition of the leased equipment by considering the values of the equipment,rent,maintenance and failure costs.Finally,a solution method was constructed based on NGSA-II algorithm and the effectiveness of the proposed maintenance strategy was verified through a numerical example.
