Multi-Agent Interests Service Composition Optimization in Cloud Manufacturing Environment

Abstract

In order to solve the problems such as the dynamic change of historical attribute service evaluation indicators, the lack of comprehensive consideration of the interest needs of all cloud manufacturing participants, and the strong subjectivity of the composition optimization results in the process of cloud manufacturing service composition. Taking the demands of service demanders, platform operators and service providers as constraints, this paper constructs a multi-objective optimization model of cloud manufacturing service composition that comprehensively considers multi-agent interests, and introduces the time decay function to deal with the service evaluation indicators with historical attributes, which reduces the impact of the dynamic changes of service evaluation indicators. Secondly, this paper adopts the NSGA-II with the elite selection strategy to solve the cloud manufacturing service composition optimization (SCO) model, and uses the grey target decision-making method to select the optimal solution from the Pareto solutions obtained by the NSGA-II, which avoids the problem of strong subjectivity in service composition decision-making. Finally, through case analysis, it was found that the bull's-eye distance of the optimal solution obtained by the NSGA-II was reduced by at least 34.95% compared to the genetic algorithm, verifying the feasibility of the optimization model and the effectiveness of the algorithm.

“…They created a BPM framework to show how BCT may be used to provide quick, dependable, and cost-effective service quality assessment in service portfolios. Guo et al [24] built a multi-objective optimization model for cloud manufacturing service portfolios that took into account the interests of multiple subjects, using the demands of service demanders, platform operators, and service providers as constraints. Ren ML et al [25] presented a synergy-based service composition approach in order to improve the social collaboration features of manufacturing services.…”
