1. The R&D Department is planning to bid on a large project for the development of a new communication system for commercial planes. The accompanying table shows the activities, times and sequences required. Activity A Immediate Predecessor Time (weeks) 3 B A 2 C A 4 D A 4 E B 6 F C,D 6 G D,F 2 H | D 3 E,G,H 3 Draw the network diagram showing: a. a.1 Forward Pass Calculation a.2 Backward Pass Calculation a.3 Float Calculation b. What is the critical path? c. Suppose you want to shorten the completion time as much as possible, and have the option of shortening any or all of B,C,D and G each two weeks. Which would you shorten? d. What is the new critical path and earliest completion time? 1.
