Module division and configuration modeling of CNC product–service system

Abstract

Product–service system is a new globally optimized production system with high-degree integration of product and service, which is formed under the product lifecycle management thinking of manufacturing enterprises. This paper applies the modular design method in the development of CNC product–service system and studies the module division and configuration modeling method oriented to configuration design process. First, a service module division method based on design structure matrix is proposed, and the relationship of service activities is established through directed graph and the module division of service activities is determined by calculating reachable matrix. Next, the product–service integration strategy is analyzed, the product–service integration model is built, and the organic integration of product and services is achieved. Then, the meaning of configuration model of product–service system is introduced and the configuration model is established. At last, the economical turning center is selected as an example of CNC to implement the module division and configuration modeling of CNC product–service system and to verify the feasibility of proposed methods.
