Service-driven approach to life-cycle dynamic evolutionary update of modular product structure

In recent years, product service system (PSS) has been paid more and more attention. Providing personalised products for customers is one of the most important services. The modularity based customisation is an effective means for it. For better customisation, the update of modular product structure (MPS) is necessary, which is the key to maintain the competitiveness of products. Therefore, the update approach of MPS for the life-cycle dynamic evolution is studied, and the problems that need to be solved emphatically are discussed. In view of the different objects concerned in the whole life cycle, a phased evolution system of MPS is constructed. Based on this, the driving factors, levels and ways of update are analysed accordingly. Then four analysis indicators are proposed to determine whether to update, and the technical supports of evolutionary update are illustrated. Finally, through the analysis of the process of dynamic evolution and update of micro-cultivator MPS, it shows that the dynamic update of MPS in the whole life cycle can maintain the ability of PSS to respond to market demand quickly, and lay a foundation for providing high-quality personalised service.
