计划关键路线是计算机在建筑行业中最早的用途之一，不过经过了很长一段时间，这一方法才得以广泛承认。

Critical path scheduling was one of the earliest applications of computers in construction, but it took quite a long time for it to gain wide acceptance.

在实际工程中工序的资源量是受到严格限制的，传统的CPM法不能给出正确的工序总时差和关键路线。

In the practical engineering processes, the amount of resources is strictly limited, so in the actual engineering, the traditional CPM can not give the correct total float and critical path.
