Abstract


Service-oriented architecture (SOA) is a state-of-the-art business logic and computing concepts , service-oriented development is an important supplement to the object-oriented , process-oriented and database-oriented development . Service-oriented development approach is becoming the latest technology solutions reflects the modular , to promote the distribution of complex information systems function . SOA solution during the execution of business processes to establish not only the enterprise information strategy and is a key process in the enterprise information system . Therefore , to study a combination of language as a starting point to build a good SOA process is very worthy of study . This article uses a popular service orchestration language BPEL business processes . Web services through a combination of scheduling and coordination , top-down service-oriented architecture . The BPEL language are the expression ability will make it , but the complex the BPEL structure on the semantics are not very clear , so the high demands of the the BPEL program of correctness in practical applications . In order to better understand the BPEL process , need to adopt a formal modeling its process modeling. This article uses a simple process algebra (FSP) formal methods BPEL semantic description , and some simple BPEL process mapping into LTS in Fig . Thesis concurrent processes sharing resources for specific research object , the establishment of the BPEL process model . Then, using a model checking tool SPIN, which is suitable for the parallel system and protocol conformance analysis to verify completion of the formal model . The paper realized the conversion between BPEL process to the SPIN model checker input language Promela , and successfully verified ; , concurrent processes sharing the resource protocol design its Kripke structures and LTL model . Separately in the model checker SPIN will Kripke structure maps Promela language the LTL formula embedded Promela program tested . Support the preparation of the simulation and verification . Finally , the work done on this article summarizes and follow-up recommendations .
