关键路径法(critical path method)

The critical path in a schedule network is the path that:

A.Takes the longest time to complete

B.Must be done before any other tasks

C.Allows some flexibility in scheduling a start time.

D.Is not affected by schedule slippage

E.All of the above.

● Your team has prepared a CPM schedule for your review. You notice that one node has six inputs (including two dummy activities) and four outputs (which include one dummy activity). Select the correct statement from the following:

A This is a valid representation if the logic is correct.

B This is invalid because a node can have a maximum of one dummy input representation if the logic is correct.

C This is invalid because nodes cannot have both dummy inputs and dummy outputs.

D This is a invalid because the number of outputs must equal the number of inputs.

E This is invalid because a maximum of two inputs and two outputs are allowed using the critical path method.
