Consider the following project network with normal activity times (in weeks) associated with each node. By adding more resources, some activities may be completed in less than their normal time. The crash times and associated costs per week are given in the table below. B Reference: In-Class Paper Manufacturing Project The critical path is A.A-C-F-H B.A-C-E-G-H C.
