A Novel Approach for Realizing Business Agility through Temporally Planned Automatic Web Service Composition using Network Analysis

摘要

The building block of Service Oriented Architecture is web services. Web services are self contained, self describing, modular applications that can be published, located and invoked across the web. Composite services are built by aggregating elementary services by a process called web service composition. Web service composition can be classified into manual and automatic types. The first type involves design time composition when the architecture and design of the software system is planned. The second type automatic service composition involves composing web services automatically to facilitate ease of composition process for engineers. Automatic composition is generally guided by dynamic composition to handle non determinism at run time. Automatic composition can be materialized as an artificial intelligence planning problem. Planning represents a part of the world as states and changes in those states. Business agility is the ability of business to adapt efficiently and cost effectively in response to the changes in the business environment. The changes in business environment are temporal. In this paper we have devised a new algorithm called Opus deviser which targets to achieve business agility through web service composition that is temporally planned using PERT Network analysis.
