Based on the description of the different stages and characteristics in manufacturing and service process to deliver the PSS, this paper establishes a framework for manufacturing and service process integration and puts forward four kinds of typical modes, which are after-sale-based integration mode, trading-based integration mode, production-based integration mode and design-based integration mode. With analyzing the function and inter-relationship of members in supply chain under each mode, the value realization and the key points of implementation of each mode is demonstrated with actual cases.
