The Research And Application Of Workflow Resource Management In ERP System

Resource management has always been an integral part of the workflow management, and resource scheduling has a direct impact on the efficiency of workflow system. In traditional workflow system, workflow management system always makes use of a certain mechanism in resource scheduling, and ignores resource constraints between the workflows, which makes the resources conflict can't be controlled effectively and coordinated reasonably.Generally speaking, when the resources conflict happened, it allocated resource by the fixed priority in traditional method, process instance with high-priority used resources firstly. However with the increasing complexity of the workflow, resource scheduling has become more and more complicated. Since the information of the processes and resources are constantly changed, it can't solve the problem of resource scheduling between complex processes using the fixed priority. It is lack of flexibility to allocate resource, and doesn't meet the demand of resources optimization.The paper summarizes the study situation of resource scheduling on abroad, analyses the resource model of workflow management system. And then in order to meet the practical need, we introduce a rule-based dynamic resource scheduling method. This method firstly use the pre-allocation of resources, introduces the usage time of resource into resource model. Before the instance of the process, we detect the potential resource conflicts between different workflows by using related algorithms. Furthermore, we introduce the concept of rule and use RCA forms to define the rules. When the resources conflict happens, the resource manager calculates the process priority with the Gaussian function dynamically and constrains the resources competition with rules. The method re-allocates and optimizes the resources by combining the processes and resources information so that it can provide real-time resource scheduling information on business flow. Finally, this method is applied to the laboratory project Huafu Printing & Dying Ltd. Enterprise Resource Planning (HFERP). It changes the traditional mechanism of single distribution or human decision so that user could make resource scheduling according to system suggested, and improves the system performance.
