摘要：The Web is moving from the collection of pages toward a collection of services that interoperate through the internet. Constitution of web services is a promising approach for the integration of global enterprise applications functionalities. When a request is given, there may be multiple web services required and invoked to assemble into a solution. Hence, the composition graph generated for a given user request may have multiple candidates with various qualities at each task level. Also, several composition paths may exist to provide the same solution with different accumulated quality. The existing system solves the problem using optimal path selection using sequential web service composition. In Sequential composition, the best path selected among the multiple paths available but, it is a time consuming process. Ultimately, performance is an issue in this system. The proposed System overcomes the complexity of the existing system. Parallel web service composition approach provides the choice to the users to select the optimal path quickly. This approach is efficient in the web service composition. This is implemented by using Dijkstra with heap algorithm through BPEL process
