Abstract

This PhD thesis has as main goal the propose of a system where it is possible to evaluate different approaches for automatic composition ofWeb services, based on QoS parameters that depend on the execution to be measured. The goal was reached by means of the implementation of a system named AWSCS (Automatic Web Service Composition System). The AWSCS is a system where it is possible to implement different approaches for automatic composition of Web services and also to execute the resulting flows from these approaches. Aiming at demonstrating the results of this PhD thesis different scenarios were developed, where empirical flows were built to demonstrate the operation of AWSCS, once algorithms for automatic composition were not found to download in the literature,. With the results it was possible to study the behavior of running composite Web services, when flows with the same functionality but different problem-solving strategies were compared. Furthermore it was possible to observe the influence of the load applied on the running system once the type of load submitted to the system is an important factor to define which approach for the Web service composition can take to the best performance according to the environment and types of load it will receive when in production.
