EX8-6 (Algo) Compute the early, late, and slack times... Compute the early, late, and slack times for the activities in the network that follows, assuming a time-constrained network. Note which activities are critical, and determine the critical time-constrained project duration. Note: Recall that in the schedule resource load chart the time-constrained scheduling interval (ES through LF) has been shaded. Any resource scheduled beyond the shaded area will delay the project. "TP" stands for time period.

Assume you have only four resources and you are using software that schedules projects by the parallel method and following heuristics. Schedule anly one period at a time! Minimum slack Smallest duration Lowest identification number Keep a log of each activity change and update you make each periode.g., period 0-1, 1-2, 2-3, etc.). The log should include any changes or updates in ES, EF, and slack times each period, activities scheduled, and activities delayed. (Hint: Remember to maintain the technical dependencies of the network.) Use the resource load chart to assist you in scheduling. List the order in which you scheduled the activities of the project
