Managing Projects: Network Diagrams A new project is underway by ECU, Inc. in North Carolina to build a new distribution hub near Elizabeth City, N.C. The specific project activities are described below and include land development, procurement of materials, and construction of the new hub. A bid has been submitted by Greenville Incorporated to build the hub. It involves a total cost of $30,000,000 and a total timeline, start to finish, of 35 weeks, which was initially accepted. However, CSX, Inc. has now come back and asked to see where the project can be "crashed and the potential cost. The following information is the initial bid on the project by Greenville Incorporated, including crash potential and cost per week. Cost Per Week to Crash Activity Immediate Predecessors A B D Duration (Weeks) 6 5 8 4 # of Weeks Activity can be Crashed 3 2 2 1 B.C $350,000 $415,000 $150,000 $550,000 $1.2 million 9 5 E F G B D E.F 7 10 2 $300,000 Question 1: Using the information in Table 1, develop a network diagram for this project. Question 2: Calculate the critical path for this project Question 3: Using the information above and your calculations from Questions 1 and 2, calculate the incremental cost and total cost to crash this project all possible weeks. HINT: Use the example chart from slide 32 (Chapter 14 slides)
