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. The tables below are actitvites slack times and number of workers required respectively. T1. (slack) T2. (workers ) i. 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. ii. 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
