Research On Flexibility Of SOA Based Business Process Management System In Electronic Commerce

Nowadays, with the increasingly fierce global competition, it is urgent for enterprises to break down their traditional roles tied with functions, and build quick-responding real-time enterprises in the complicated and ever-changing business environment. Unfortunately, the former IT principles, methods, techniques, systems and tools used in BPR and BPM are gradually giving birth to more and more shortcomings.Embarking from the BPM's perspective, this thesis discusses the dilemma of flexibility enterprises meet when carrying out BPM in business context and summarizes the flaws of traditional workflow techniques concerning flexibility. Following this, suggestions on how to make the enterprise business process more flexible are proposed: designing and building SOA-based and flexibility-enabled techniques and systems.The major research work of this thesis is as follows:To begin with, this paper details the strategic lay of BPM's connotation and divides this into three parts: Horizontally-building a controllable, end-to-end business process across the whole value chain; Vertically-setting up business-driven, top-down, organization-wide framework of workflow management and resource integration; Time-establishing the mechanism of closed-loop management and gradual optimization across the business process life cycle. Thereby the three-dimensional BPM model has been put forward.In addition, this paper chooses technical standards according to the developing trends in this area and designs SOA-based architecture from multiple angles, namely BPM integration level architecture, BPM lifecycle architecture and BPM component architecture. It also gives a detailed description of the relationship and collaboration between the modules under the different architectures. Thus, an all-round, multi-level, three-dimensional analysis of the BPM system architecture for the support of flexible process has been presented.Furthermore, this paper analyzes, together with key points for flexibility, the flexibility-enabled theory based on the proposed BPM architecture. Also included in this section is a package of flexible strategies and frameworks for technical solutions.Lastly, a specific case is studied. The obstacles of realizing flexibility in BPM for PT, a computer manufacturer, are analyzed. Then requirements analysis for flexible process is performed. Afterwards, based on the methodology previously discussed, a flexible core process is designed and a prototypical system using Oracle BPEL Process Manager and other necessary softwares is developed. Finally, the strategy of implementation and a road map for realizing flexible BPM for the company is given subject to the state of the country and the business status of the company.
