Study And Implement On RFID Business Process Execution Engine Technology

Integration bewteen RFID and enterprise business process has become an important aspect in the research field of RFID. But most of the existing RFID business process integration solutions are on the traditional business process engine, and can not meet the needs of RFID business process well. And there are not any effective methods to directly run the business process language which is suitable for business people. Current methods are all running those languages through the model transformation which will result in the loss of model accuracy. This paper focuses on the research of RFID business process execution engine to solve these problems.This paper describes a PVM-based, multi-language-supported, and RFID-supported business process engine architecture. We Select a business process modeling language EPCs which is easy to be learned and used by business people. We extend EPCs to an executable modeling language EPEL. And we choose to support another business people oriented modeling language: eBPMNL. We design directly execution algorithms for these two languages to avoid the loss of model during tranformation and provide more choices to business people by supporting multiple business process modeling languages. The engine directly provide good support for RFID. The business process can be directly driven by the RFID event. In this way, we improve the efficiency of RFID integration and eliminates the extra cost.This paper first introduces the background and current situation of RFID business process execution engine technology, and then introduces the contents of study and innovation points of this paper. Secondly, this paper introduces some current mainstream RFID business process engine technologies to analyze their characteristics and the common shortcomings, then we put forward the research idea of this paper, and introduce some related works. Then this paper gives the architecture of RFID business process execution engine and research on the key technologies of the engine in detail, including the RFID support mechanism, the extensions of EPCs modeling language, EPEL business process execution algorithm, eBPMNL business process execution algorithm. After that we describe the concrete implementation of the various parts of the system. A scenario is given to make the system demonstration. Finally, we summarize the entire paper, look ahead to the future of the RFID business process execution and propose some future works.
