4. Given the following network with activity times in months, determine the earliest and latest activity times and slack for each activity. Indicate the critical path and the project duration.
5. In one of the little-known battles of the Civil War, General Tecumseh Beauregard lost the Third Battle of Bull Run because his preparations were not complete when the enemy attacked. If the critical path method had been available, the general could have planned better. Suppose that the following planning network with activity times in days had been available. Determine the earliest and latest activity times, and activity slack for the network. Indicate the critical path and the time between the general’s receipt of battle orders and the onset of battle.
6. A group of developers is building a new shopping center. A consultant for the developers has constructed the following project network and assigned activity times in weeks. Determine the earliest and latest activity times, activity slack, critical path, and duration for the project.
7. 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. Construct the network for this project, identify the
