Multiple BPEL execution engines based on fragmentation approach and application of service process models

To solve united process customization and collaboration problems of various organizations, service process models fragmentation approaches based multiple BPEL execution engines were proposed. Firstly, a whole consistent model is partitioned as several self-contained implementation sub-chips which are sent to a number of BPEL execution engines respectively based on the different organizations and roles. And based on high-level Petri net puts forward the horizontal fragmentation methodology. Further, this paper verifies correctness of model fragmentation. Then the distribution after fragmentation is also presented to improve the reliability and availability of BPEL execution engines. Finally, this paper illustrates with a business process instance of enterprise supply chain that the fragmentation of process implementation is adaptive to autonomy together with decentralization of services, and can improve the flexibility and interoperability of BPEL execution engines.1
