There are support systems for developing cooperating Web Service applications for writing a Business Process Execution Language (BPEL) scenario. However, these systems are intended for Web Application developers since end-users cannot write scenarios without web application skills. There are two problems with these systems: writing a scenario is difficult and end-users cannot develop complex ones using these systems.To solve these problems, we propose a new support system for scenario writing in which a service composition application can be easily developed using the weight from a component rank method, such as Page Rank by Google. Our system is not only used when considering the history of a developer to estimate the rank, but uses end-user history, which is the number of time end-users used scenarios. As a result, our proposed system can be used to easily produce a new complex scenario. We also conduct a simulation of the proposed system and compare it with the current support systems to show its effectiveness.
