摘要:Web services distributed in the internet can be integrated into a composite service for meeting the enterprise needs. QoS driven web service composition is the current research area in web services. There are many research papers published for quality enabled web service composition. However, only a few researchers focus on the multi-quality criteria for web service composition. Extraction of the quality optimized composition path from the web service composition graph generated during the validation phase of the web service composition is a research problem. In this paper, we propose a multi-criteria QoS decision making model for the optimal execution path selection from the web service composition graph. Extended Simple Additive Method (ESAW) has been proposed for calculating the changing qualities during dynamic composition. Our method can be applicable for local as well as global optimization of web service composition. By applying this new decision making model the success ratio of dynamic composition of web services are calculated and compared with the existing Simple Additive Method (SAW) for static composition. Results prove that success ratio of composition requests are considerably increased by the proposed method.
