【摘要】 针对当前工作流产品不能互操作及对异构的分布环境支持不足等问题,提出了一种基于BPEL的工作流引擎调度技术,该技术以流程模型映射成的并且支持跨平台调用流程的BPEL文件的解析、定义获取当前任务的相关数据为流程引擎控制调度的基础,通过对当前节点类型的判断,后续节点的可执行性的确定,多个后续节点的同步、异步执行的确定以及多支路的选择来推动整个流程的执行。最后通过实例验证了此方法的可行性。更多还原

【Abstract】 The current workflow products can not interoperate and be the lack of support for heterogeneous distributed environment.It proposes the scheduling technology of workflow engine based on BPEL.On the basis of analysis and definition for the current task and the relevant data,it generates the BPEL files.By determining the current node type,the enforceability of the follow-up node,multiple follow-up nodes synchronous and asynchronous execution,it promotes the implementation of the entire process,as well as multi-branch selection.Finally,an example proves this method feasible.更多还原
