1.请按照事件1的要求,帮助张某完成此项目的单代号网络图。

答案

参考答案:项目的关键路径为ACDGH;项目的工期为44天

解析:依题意,列出图1-5中的所有路径,并计算各条路径的工期(即时间跨度),如表1-7所示。

表1-7 某项目各条路径的工期
序号 路径 工期(天) 序号 路径 工期(天)
1 ABDFH 5+2+10+10+10=37 4 ACDGH 5+8+10+11+10=44
2 ABDGH 5+2+10+11+10=38 5 ACEGH 5+8+5+11+10=39
3 ACDFH 5+8+10+10+10=43
关键路径是一个相关活动序列,该序列具有最大总和的最可能工期。在表1-7中,由于44>43>39>38>37,因此路径ACDGH为该项目的关键路径。关键路径上各个作业时间之和就是整个工程的计算工期,它决定了项目最早可能完成的时间,即该项目的工期为44天。
