An Improvement of Service Scheduling Based on Market Mechanism and Semantic*)

摘要

We compare some present resource scheduling methods and discuss the importance of combining the market mechanism with semantic,we advance model of service scheduling based on market mechanism and semantic (Market-Semantic). It includes the similarity measure between ontologies,the ascertaining of utility functions and resource price. By changing a new method to measure the similarity between ontology,and by looking on the ratio of capability and cost as the utility functions,we optimize the method of service scheduling by which users not only can get the service satisfied,but also the resource can be allocated more efficiently,Finally,the experiment proves that our method is better than the methods of Max-Semantic and Semantic-Cost-Max-Min.
