Research and implementation of dynamic task scheduling based on workflow

Through the study of the solutions of Enhydra Shark and Jboss JBPM for the problem of allocating task dynamically in the implementation of the workflow and the deficiencies of their solutions. Sub-processes is used to achieve dynamic allocation of tasks to meet the changing needs of customers and complex business logic processing requirements. When executor carried out its task, a suitable sub-processes templates is choosen with more flexibility according to the business needs, avoiding the drawbacks of pre-defined sub-process templates. In distributed workflow applications, executor can choose local workflow process templates to finish foreign domain tasks. Finally, the design of the solution is given and is applied in the documents submitted of the actual projects, good results are obtained.
