Background: Nowadays, web services are one of the most widely used groups of SOA and service computing. The problem of QoS based selecting a web service dynamically and composing a set of web services to conduct a business task has been investigated in this paper. One of the main objectives of this paper is selecting web services based on non-functional properties and QoS score.

To select a web service for eachtask SAW method is used, but this method don’t apply SAW method on all of web services. It use user requirements for ranking set of candidate web services and finally apply SAW method on set of candidate web services. Result: This method will help to select web services based on QoS score and user requirements. Select web services among many number of web service with this method can use to composition web service and finally will help to optimize response time of web service composition. Application: .NET Application with Visual Studio Environment and C# Programming Language.
