activities in the network

1. 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 the time-constrained scheduling interval (ES
through LF) has been shaded. Any resource scheduled beyond the shaded area will delay the
project.
Assume you have only three resources and you are using a computer that uses 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, 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. Which activities of your schedule
are now critical?
Recompute your slack for each activity given your new schedule. What is the slack for activity 1?
4? 5?
2. Given the time-phased work packages and network, complete the baseline budget form for the
project.
