| 摘 要： | 作业流，也称作业网络，是相互关联的作业形成的一个偏序集。由于作业间存在着顺序、分支、循环、并行、同步、异步等依赖关系，因此作业流可能非常复杂。如果没有一个良好的定义准则，那么生成的作业流将结构混乱，不利于查错、解析，也不利于可视化显示。该文归纳了作业间的依赖关系，提出了作业流的结构化定义方法。这种方法简单地表达了作业间的多种依赖关系，它也能表达作业流间的层次和嵌套关系。

| Abstract: | Job-flow, also called job-nets, is a partial set of jobs which are related to each other. A job-flow may be extremely complex resulting from all kinds of dependencies between jobs, such as sequential, conditional, iterative, parallel, synchronous, asynchronous and so on. If there is no good rule to define job-flow, then resulting job-flow may be confusing, and difficult to check, analyze and visually show. This paper summarizes the dependency relationship between jobs and provides a structured method of job-flow definition. This method briefly describes the dependencies between jobs, it can also define nested job-flow. |
