Developing Game Models for Service Composition to Improve Customization in the Equilibrium State Based on Cloud Manufacturing System

Abstract

The Selection of appropriate Quality of Service (QoS) strategies is an important subject for manufacturing service providers. The subject is more important in the Cloud Manufacturing System (CMS) based on the numerous and diversity of Manufacturing Cloud Service (MCS) providers. The direct interference of the consumers in determining the end value of QoS is a novel problem in CMS. Also, the interference of consumers is an aspect of customization in Cloud Manufacturing as an Industry 4.0 paradigm. The research develops two models for service composition to improve the customization in CMS based on game theory. The models are developed based on the Stackelberg game and the non-cooperative game. The consumers and MCS providers are the players in the game models. The players select the strategies to improve their benefits in the games. According to the results, the consumers get better benefits in the Stackelberg game than the non-cooperative game. Also, the MCS providers get appropriate benefits in the Stackelberg game model. The QoS value in the Stackelberg game model is higher than in the non-cooperative game model.
