A System Dynamics Model for the Diffusion of Cloud Manufacturing Mode With Evolutionary Game Theory

Cloud manufacturing (CMfg) is emerging as an advanced green and efficient manufacturing mode for the manufacturing industry. It has gained extensive attentions owing to the unique manufacturing mode and advantages. However, current research pays little attention on the diffusion and adoption of CMfg mode. Based on the diffusion of innovation (DOI) theory, in this study a three-stage diffusion model of CMfg mode is developed from the perspective of manufacturing enterprises. Furthermore, the system dynamic (SD) approach is employed to study the CMfg mode adoption behaviors of manufacturing enterprises. The causal loop diagrams including user market submodule, enterprise revenue submodule and diffusion module are analyzed firstly, and a SD diffusion model with evolutionary game theory is established. At last, CMfg diffusion process is simulated by considering the commission rate, government's subsides, user membership fee of cloud platform and user acceptance intention The results show that subsidy for enterprise users is better than that for CMfg service providers in promoting the diffusion of CMfg mode. User acceptance intention and membership fees are another two key factors.
