The Algorithm of Web Services Composition of Group Decision-making Based on Fuzzy Numbers

In order to improve the efficiency of web services, it is necessary to evaluate the integrative performance of web services composition. Aimed at the problem of the diversity of quality evaluation as well as the description of the vagueness of the language, in view of the fuzziness and diversity of service evaluation attributes, this paper proposes a group-decision service composition method based on fuzzy numbers, which can realize service evaluation by triangular fuzzy numbers. Unified processing and quantitative description of service composition are carried out, and multi-attribute group decision-making method based on cut-set matrix evaluation is adopted to optimize service composition. Finally, it proves the reliability of the algorithm through the web services combination of case analysis and simulation experiment, and improves the service quality of the combination.
