摘要
根据语义进行服务调度,是服务计算的重要内容,服务调度是一个寻优的过程。为了解决当前服务调度不能很好地兼顾语义、效率与收益这个问题,提出了粒子群寻优算法(PSO)、本体和市场相结合的服务调度方法,开发了粒子群寻优算法与本体和市场机制相结合进行服务调度的算法SBPOM(Service scheduling Basedon PSO,Ontology and Market),从而为用户获取满意的服务提供了一种有效的方法。实验表明,利用粒子群算法寻优,既提高了寻找服务调度方案的速度,同时也兼顾了根据语义进行服务调度,保证了资源的高效使用。
Service scheduling based on semantic is important in service computing,and service scheduling is an optimal process.As the current service scheduling method can not very well considerate the efficiency and the semantic,we researched the way to combine the PSO,ontology and market mechanism,and proposed the method SBPOM to schedule service based on them.This method may improve the service scheduling and it provides an efficiency method for users to get the service satisfied.Experiment shows that our method takes full advantage of the capability of PSO,service sche-duling and resource using are efficiency also.
