A practical scheduling method based on workflow management technology

Abstract

In literature, most scheduling models are developed using mathematics method such as programming model or graphic model such as Petri net. Although they are efficient in computing, they are difficult to be built and understood by the industry users. In order to make the scheduling model more capable and practical for industry use, a new scheduling model based on workflow management technique (SMWMT) is proposed here. It is a process oriented compound model that featured as various process constraints definition, activity behavior description, flexible resource definition and mapping, and graphic presentation that offer intuitional understandings to users. The corresponding scheduling system based on workflow simulation is provided. A cost oriented iterative algorithm is proposed to enhance the scheduling performance. The example of the model and the simulation results show that the proposed model and scheduling method are effective.

An introduction to Chinese manufacturing research institutions

“…A workflow technology based scheduling model has been developed using activity based modelling and event condition action (ECA) rules embedded in the activity definitions to reduce the model scale and improve the dynamic description capability. In addition, an independent resource model was used for better definition and allocation of resources (Lin et al 2003). (d) Researchers present the mathematical model of optimal scheduling for deadlock avoidance in manufacturing systems based on the concept of resource allocation function, aimed at reducing the system total processing time.…”

Service Modeling Optimization and Service Composition QoS Analysis

“…It contains a number of primitive activities as well as structured activities. On the other hand, this leads to complexity of BPEL4WS and low-performance modeling and running (Cao, Chan, & Chan, 2005;Lin & Fan, 2003;Wang, 2005). To improve the ease of use and running performance, we need a method and tool that can simplify business process modeling and optimize the BPEL4WS model for running.…”

Resolving heterogeneity of Web-service composition in network manufacturing based on ontology

“…Currently, workflow technology (Lai andFan 2002, Lin and has become kernel technology in order to automatically improve business process, and it has been widely applied to enterprise integration systems (Lin and Fan 2004) to realize the interoperation among partners. However, the integration of workflow technologies with Web services has presented a trend for dynamic business in a Web environment; for instance, workflow systems together with Web services, and the platform supporting Web-service composition based workflow technologies are proposed.…”
