Research on "Location-Inventory" Problem of Spare Parts Supply Chain Based on Product Service System

Abstract On the one hand, product service systems generally provide better services to customers at the expense of service providers, such as product interaction design. On the other hand, there is a small amount of literature focusing on meeting customer needs, reducing the interests of service providers, and almost no the literature focuses on improving the profitability of service providers by focusing on product service systems. From the perspective of supply chain network design, this paper studies the “location-inventory” problem of multi-level parts network, and focuses on how to reduce the cost of service providers and increase their profits.
