Manufacturing Cloud Service Composition Based on the Non-Cooperative and Cooperative Game Theory

Abstract

The production environment and its related supply chain have faced with enormous changes by Industry 4.0 (I4.0) emergence. Cloud Manufacturing (CM) is one of the paradigms of I4.0. Composition of Manufacturing Cloud Service (MCS) is an approach for developing the composite services in Cloud Manufacturing System (CMS) considering the MCS providers. Game theory is considered as an effective approach for developing models according to real-world conditions for MCS providers' cooperation and competition. This research proposes a profit function and then develops a mathematical model for MCS composition using game theory and the proposed function. The MCS providers compete with each other in non-cooperative and cooperative games according to the proposed mathematical model. The result of research demonstrates that the cooperation game is more profitable than the non-cooperative game based on the formal cooperation among the MCS providers. Therefore, the payoff of players in the cooperative game is higher than the non-cooperative game. Also, the level of Quality of Service (QoS) in the cooperative game is greater than the game type of non-cooperative. Therefore, the model of cooperative game satisfies the consumers and the MCS providers mutually. The paper recommends applying the cooperation game to service composition in the CMS.
