里程碑图是一个目标计划,它表明为了达到特定的里程碑,去完成一系列活动。里程碑计划通过建立里程碑和检验各个里程碑的到达情况,来控制项目工作的进展和保证实现总目标。
我们使用状态转换关系图来描述这一模型,其中状态代表里程碑,转换代表促使变成该状态的事件。
We used a state-transition diagrams for this model, where the states represent the milestones, and the transitions represent events that cause changes in that state.
对于每个里程碑,有一组可以被配置的关联动作(图1中的a圆圈)。
For each milestone there are a set of associated actions (the a circles in figure 1) that can be configured.
