E 1. The following project with resource needs as stated is in planning. Activity Immediate Resources Used Assigned Resources Predecessors A 9 Person Days, Worker Type A 3 Worker A B A 30 Person Days, Worker Type A 6 Worker A C A 21 Person Days, Worker Type B 3 Worker B D B.C 9 Person Days, Worker Type B 3 Worker B CD 9 Person Days, Worker Type A 3 Worker A F E 12 Person Days, Worker Type B 4 Worker B G E 9 Person Days, Worker Type A 3 Worker A Prepare a network diagram for this project. A person day is one person working 8 hours in a day on an activity. Only 1 work shift of 8 hours is scheduled on a day. Count only workdays when reporting answers and calculating duration a) Under the assumption that up to 6 worker A's and up to 6 worker B's are available for assignment at any time to this project, what is duration in days of the project based on the stated assigned resources? Round up to integer value days for activities if rounding is required from the arithmetic. b) Prepare a resource use requirements plan for the schedule from part a. How many Worker B's are required on day 17 of the plan? c) For the plan from part b, how many worker type A's are required on day 17 of the plan? d) Under the restriction that at most 3 worker A's and 3 worker B's can be made available to work on the project on any single day, adjust the staff assignment and duration of activities. Increase Worker B staff on an Activity to 3 if the current assignment is less than 3. Keep fractional durations if the duration results are fractional. What is duration in days of the project? Round up to integer value days if rounding is required from the arithmetic for the final duration Note that activities in parallel cannot be completed in parallel if staff required to do so exceeds the limit of staff available each day
