Abstract


Information systems with the socio-economic development is the growing importance of enterprise development and competitiveness in the fierce competition led to constantly adjust the structure of information systems , unified management workflow technology , workflow management system of the business process , has become new trends in information systems . Possible only for approval function in an office automation system , with the gradual refinement and increase in the sector of the corporate division of labor , the approval process is complicated , especially some of the major projects of the application approval process , at the same time need the consent of the several departments application is successful, the so-called countersigned . Face the approval modeling of complex processes , Petri net modeling graphical representation solid theoretical foundation , mature analysis and verification methods , but in some ways can not meet the modeling of complex processes , such as not modeling color, time , and the hierarchical structure of the model is not clear . On the basis of theoretical studies the approval system characteristics and practical issues of the China National Gold Group , learn and extended time in the classic Petri nets based on hierarchical Colored Petri Nets (HTCP-net) as a modeling theory contained countersigned model approval process and verify the correctness and to use workflow as a the workflow net implementation technologies in the Web services environment , study the specific application of workflow technology in the workflow management system , and the use of related technologies to achieve China gold Group 's information management system approval subsystem . This study to solve the problem of the enterprise parallel processes approval , contains countersigned approval system similar reference .
