Workflow management system and management method based on knowledge

Abstract

The invention discloses a workflow management system based on knowledge, comprising a local workflow module, an SDEM (Service Distill External Model) module, an RDQL (Resource Description Query Language) module and a DB (DataBase) module, wherein the local workflow module is connected with the SDEM module to submit the information of a workflow node to the SDEM module; the SDEM module carries out format conversion to received information and sends a RDQL query sentence containing feature body attribute to the RDQL module connected with the SDEM module; the RDQL module is connected with the DB module to inquire data; the query result is transmitted to the RDQL module; the RDQL module forwards the received query result to the SDEM module; after the query result is subjected to format conversion, the query result is sent to the local workflow module; the traditional workflow module and a knowledge base module are combined; and a main body concept is used for describing the workflow, and the workflow model is endowed with a corresponding dynamic semantics by the knowledge expression ability of the main body technology, so that a workflow system has the capability of dynamically analyzing and optimizing the workflow engineering so as to improve the performance and the efficiency of the workflow.

Description

technical field [0001] The invention belongs to computer application technology, more specifically a knowledge-based workflow management system and management method. Background technique [0002] Existing workflow modules start with process definitions, such as flow charts, state diagrams, and activity network diagrams. The advantage of this type of directed graph model is that it is more intuitive and easy to understand. In general, the nodes in the graph represent the activities or states in the process, and the directed arcs represent the timing dependencies between nodes. Existing workflow products are based on an assumption: processes can be defined in advance. [0003] However, some activities are unpredictable in reality; it is difficult to pre-define all execution paths; users need to optimize the process frequently. In the traditional workflow management method, every time there is a workflow that does not exist in the table, it must be added. In the long run, t...

Problems solved by technology

The workflow management system is not the business system of the enterprise, but provides a software support environment for the operation of the business system of the enterprise. Traditional WFMS has limited integration capabilities for business systems, and it is difficult to cross-platform and cross-organization, and cannot handle complex process logic. , lack of flexibility
