You are working on a software development project. On this project, a number of tests must be performed, including some that must be performed multiple time. The project includes activities whose sequence is conditional based on the outcomes of prior activities. For example, if an error is discovered through inspection, the project’s design may have to be modified, creating the need for additional testing. The network technique best able to handle these situations is ______ .
A．PDM network
B．PERT chart
C．GERT network
D．ADM network
参考答案：C
解析： 你正致力于一个软件开发项目。在这个项目中, 必须进行大量的测验, 其中一些测验必须进行多次。这个项目中有一些活动的顺序是以前面的任务结果为条件的。例如, 在检查过程中发现了一个错误, 项目的设计可能要修改, 这样就需要额外的测验。能够更好地处理这些情况的网络技术是 ______ 。 A) 优先序列网络图(PDM) B) 计划评审技术表(PERT) C) 图形评审技术网络图(GERT) D) 箭头图示法(ADM) 本题描述情况为需要根据条件设计下一活动。GERT允许存在分支和回路，可以满足需要。
