Study on the utility model and utility equilibrium of resource service transaction in cloud manufacturing

As a new service-oriented network manufacturing model, cloud manufacturing (CMfg) can accelerate the transformation from production-oriented to service-oriented manufacturing. Study of resource service transaction (RST) is one of the key issues that deciding the practical application of CMfg. In this study, the comprehensive utility models considered the revenue, time, and reliability for the three sides, i.e., resource service provider (RSP), resource service demander (RSD), and resource service agent (Agent) in the RST process in CMfg under the decentralized decision-making condition are first established, respectively. Then the comprehensive utility model for the RST chain (RSTC) of “multiple RSP-one Agent-multiple RSD” under the centralized decision-making condition is proposed and discussed. The existence of utility equilibriums between RSP and Agent, Agent and RSD are proved in the optimal decision of the RSTC under the decentralized decision-making condition.
