一种QoS感知的基于着色Petri网的Web服务动态组合研究
STUDY ON A QoS-AWARE AND COLOR PETRI NET BASED WEB SERVICE DYNAMIC COMPOSITION
摘要
Abstract
With the continuous enhancement of computer and network technologies as well as the continuous population of web services, it no longer satisfies the service requestors' demands to call only one single web service. Service composition has become an inexorable trend.The paper puts forward a QoS-aware and color Petri net based web service dynamic composition model ( QWS-CPN), explains some vital elements in the model such as color aggregations, guard functions, and arc functions etc. , and introduces a usage probability based QoS calculation method in order to enable service requestors to obtain the required web services in just a short delay.关键词
