Economic Evaluation Modeling and Application of Remanufacturing Product Service System

Remanufacturing product service system is a commercial integration system based on remanufacturing products and services to meet user requirements. Existing studies have analyzed the promotional effect of product service system on enterprise remanufacturing implementation and proposed a remanufacturing scheme-evaluation method. However, there is a lack of research on the economic benefits of enterprise implementation of remanufacturing product service system from the perspective of product life-cycle costs. Therefore, in view of this problem and considering the entire remanufacturing process, this study used the life cycle cost analysis method to comprehensively optimize the stages of recycling, production, sales, use, and scrap disposal in the remanufacturing process. Additionally, the influence of factors such as the remanufacturing cost, technology selection, and market size on the economic benefits of the remanufacturing product service system was analyzed. The economic evaluation model of the remanufacturing product service system was constructed to provide an analytical framework for enterprises to formulate a remanufacturing implementation strategy, technology, and service-mode selection. The results showed the following: (1) Enterprises implementing a remanufacturing product service system can obtain better producer benefits. When an enterprise uses advanced surface-engineering technology, the remanufacturing rate of the old blank parts is improved, the procurement cost of the updated parts is reduced, and the overall economic benefits are higher. (2) Enterprises implementing a remanufacturing product service system can obtain better user benefits. Remanufacturing product service system allow users to obtain remanufactured products with the same performance as new products at a lower cost. When enterprises use advanced surface-engineering technology to produce remanufactured products with upgraded performance, they can reduce the cost to users at the use stage, thus bringing more economic benefits to users. (3) Enterprises can obtain better social benefits by implementing a remanufacturing product service system. The implementation of these systems is conducive to energy saving and emissions reduction, reducing the cost of social environmental pollution control and resource consumption, and bringing higher resource and environmental benefits to society. Based on the research results, the following constructive suggestions for remanufacturing enterprises are proposed: (1) In the process of implementing the remanufacturing product service system, enterprises should actively develop and apply advanced remanufactured surface-engineering technology, improve the remanufacturing rate of old parts, constantly improve the performance and quality of remanufactured products, and improve the remanufacturing product service system. (2) Manufacturers of original equipment should conduct remanufacturing-oriented product designs in the process of new product development and design, improve the recyclability and disassembly of old parts, reduce the replacement number of scrap parts, and meet the requirements of more users with high-quality and inexpensive remanufactured products. (3) Enterprises should pay attention to the policy and development trend of the remanufacturing industry, actively apply a new generation of information technology to improve the level of intelligent remanufacturing, realize continuous upgrading, and iterate the remanufacturing product service system. From the perspective of product life cycle cost, this study analyzed the economic benefits enterprises can bring by implementing a remanufacturing product service system and provided an analysis framework and management environment for enterprises to formulate a remanufacturing implementation strategy, technology, and service-mode selection.
