摘要	To dynamically integrate the existing Web services to form a newly value-added and complex service to meet the requirements for different users, a Web services composition algorithm supporting Global Optimal and Dynamic Re-Planning(GODRP) of Quality of Service (QoS) was presented. A position matrix coding scheme was used to express simultaneously all of composite paths and re-planning information in the algorithm. The quality of the services composition was improved by means of calculating Hamming Distance of QoS among individuals. It was solved that the algorithm's execution time impair the QoS by prescribing a total time limit and implementing a fine solutions reservation strategy. Compared to similar studies, this algorithm provided a more integrated and effective QoS scheme of services composition in dynamic environment. Experimental results indicated the feasibility and effectiveness of this algorithm.
