Compute the early, late, and slack times for the activities in the network that follows, assuming a time-constrained network. Which activities are critical? What is the time constrained project duration? Note: Recall in the schedule resource load chart that the time-constrained "schedule interval (ES through LF) has been shaded. Any resource schedule beyond the shaded area will delay the project. Assume you are a computer using a software that schedules projects by the parallel method and following heuristics. Schedule only one period at a time! Minimum slack Smallest duration Lowest identification number Keep a log of each activity change and update you make each period-e.g., period 0-1, 1-2, 2-3, etc. The log should include any changes or updates in ES and slack times each period, scheduled activities, and delayed activities. (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. Which activities of your schedule are now critical?
