Consider project time and cost data in Table 1. The indirect cost of the project is $200 per day. 10 Table 1. Normal and crash times/costs for the project (Note: Times are in days) Immediate Normal Crash Normal Crash Task Predecessors Time (days) Time (days) Cost ($) Cost ($) 200 200 600 1,000 12 9 625 1,000 700 800 200 500 CD 9 5 _ 400 840 GE 14 10 1,000 1,440 HE, FL 10 8 1,100 1,460 6 a) Determine the project duration and the cost for "No Crash Schedule" (CPM). b) Determine the project duration and the cost for "Maximum Crash Schedule". c) Construct a Lincar Programming model to determine the optimal duration of the project and solve it using LINDO. Be sure to state precisely the definitions of your decision variables, and explain in a few words the purpose of the first three constraints. d) Using your LINDO output determine the amounts by which activities are to be "crashed" and completion times of the activities for the optimal project duration. e) Construct the project network based on the optimal solution obtained from LINDO. Determine the minimum cost of the project
