Q1. In a marketing Project, 7 initial activities are given in below. Here, capital letters denote the nodes and arcs denote the activities and respective durations. The critical path is given by bold arcs. 5 8 B The tables below are actitvites slack times and number of workers required respectively. A-D B-E B-C C-E 6 4 1 1 A-B B-D D-E A-D B-E B-C C-E 3 2 3 4 3 2 2 T1. (slack) T2. (workers ) i. ii. Please make a comparison between two policies, earliest and latest-start-time approaches of the activities, considering the number of workers required simultaneously. Please find the economic one. Now, some additional constraints are defined for the Project: a. Activity A-D cannot start until activity B-D has been in progress for at least 3 time units, b. Activity C-E cannot finish until at least 2 time units after the completion of activity D-E. Find the new completion time and the critical path. (20+20 pts)
