The Construction Of Collaborative Business Processing Platform Based On The Workflow

Since 2009 Daqing Oilfield Technology Management Platform running on the line, it had been realized the full life cycle of science and technology project management review. With the change of the management mode of science and technology, the original system exposed some problems gradually. Such as: the working process of the original was not easy to adapt to change in business update; the original routing business processing mode reduced the working efficiency, we needed to co-operate with the node to be improved; users couldn’t initiate the custom business and so on. Therefore, the topic intended to original technology management platform to improve.By building a flexible business process allocation mechanism, node multiplayer cooperative mechanism in order to improve the efficiency of oilfield technology management department, it made the system to adapt to changing business.Based on the current demand in the topic, firstly, we builded collaborative technology business model based on the workflow, extractioned and decompositioned technology management business, at the same time Instantiated the business process and introduced of webservices technology to solve the problem of information platform data exchange and transmission. Secondly, in view of the business process dynamics and synergistic requirements, we studied from workflow definition stage and implementation stage. According to the demand we expanded the workflow meta model, we discussed research in terms of version control, the node of the partial order relation and modify the strategy of process instance in the implementation stage. The topic raised a dynamic instances modify policy rule. Finally, in view of the data concurrent consistency issue in the collaborative editing child module, we used a transform algorithm of concurrent data operation to solve.In allusion to actual needs of collaborative technology business processing platform in the topic,the topic integrated construction of dynamic workflow technology and the coordinated mechanism organically and adopt the corresponding systems development methods, it provided the theoretical support and to verify for establishment of platform.finally the topic established a collaborative business processing platform supported by workflow.
