\#2) a) (25 points) Consider the following project network for a project consisting of 8 activities. Each activity needs a certain number of teams to be executed. The teams are identical. The cost of executing an activity with the given number of teams, duration and team requirement for each activity are given below. Given only 4 teams are available, schedule the project activities using parallel scheduling algorithm with the aim of minimizing the project duration. Use min slack as the dispatching rule and use SPT as a tiebreaker. Employ the time point convention starting with T=0. b) (10 points) The overhead cost per period is given to be 80000TL. Explain how you would estimate the maximum cost you would be willing to incur for increasing the number of teams from 4 to 5 teams
