【Abstract】 After analyzing of the problem model of shop-floor sc heduling, a workflow technique is put forward to solve the issue of the complex job shop scheduling. Firstly, a workflow model consisted of job model, recourse model an d process model is described. Then a platform of workflow-based scheduling syst em is set up and the description of the architecture and the mechanism of the dy namic matching job-activities and resources of the platform are analyzed. Base d on the platform, a time-driven and event-driven integrated dynamic scheduli ng m odel is illustrated. In addition, the decision-making mechanism of the workflow engineer-the heart of the platform is emphasized. Finally a workflow model of a given 6×6 scheduling problem is modeled. Based on the model the result is given and compared with the standard results. Result shows that workflow te chnique can achieve a clear model and a quick operation, thus providing a novel a pproach to solve the job-shop issues.更多还原
