Abstract: Based on the features of remanufacturing and product-service systems，a concept of RPSS was proposed.The LCA model of RPSS was established according to the LCA method framework，and the applications of the model were carried out using diesel engine RPSS as a case study.Results show that the quality and performance of remanufactured products are not inferior to those of new products，which is the key for enterprises to obtain environmental benefits through the implementation of RPSS.Enterprises may develop products designed for remanufacturing to improve the remanufacturing rate of products and reduce RPSS life cycle environmental impact.RPSS may provide enterprises with stable sources of used parts and improve their market competitiveness.

Key words: remanufacturing product-service system（RPSS）, life cycle assessment（LCA）, environmental implication, environmental benefit

摘要： 基于再制造和产品服务系统的特征提出了再制造产品服务系统（RPSS）的概念，根据生命周期评价（LCA）方法框架建立了RPSS LCA模型，并以柴油发动机RPSS为案例对模型开展应用研究。研究发现，确保再制造产品质量和性能不低于新品，避免产品使用过程消耗大于新品是企业通过实施RPSS获得环境效益的关键；企业开展面向再制造的产品设计，提高产品再制造率，可以降低RPSS生命周期环境影响；RPSS可以为企业提供稳定的旧件来源，提高企业市场竞争力。
