Problem 4 N A farm owner is going to erect a maintenance building with a connecting electrical generator and water tank. The activities, activity descriptions, and estimated durations are given in the following table. (Notice that the activities are defined not by node numbers but by activity descriptions. This alternate form of expressing activities and precedence relationships is often used in CPM/PERT.) Use POM to create a time schedule for this problem. Using the POM output and the network on the next slide, answer the questions on the next slide. Activity Activity Description Activity Activity Duration (weeks) Predecessor Excavate Erect building Install generator Install tank Install maintenance equipment Connect generator and tank to building B,C,D Paint finish Check out facility N Im > M E, F N Problem 4 Continued 1. What is the critical path for this network? 2. What is the projected length in time of the project? 3. If you needed to delay some activities due to a strike by some of the works, which activities would you delay and what is the maximum time you could delay them
