The Tinker Cоnstructiоn Cоmpаny is reаdy to begin а project that must be completed in 12 months. This project has four activities (A, B, C, D) with the project network shown next. The project manager, Sean Murphy, has concluded that he cannot meet the deadline by performing all these activities in the normal way. Therefore, Sean has decided to use the CPM method of time-cost trade-offs to determine the most economical way of crashing the project to meet the deadline. He has gathered the following data for the four activities. Use marginal cost analysis to solve the problem. What is the minimal total crashing cost to finish the project in 12 months?
