Question 1: Draw the network plan that follows, compute the early, late, and slack times. What is the project duration? Using any approach you wish (e.g., trial and error), develop a loading chart for resources Carpenters (C) and Electricians (E). Assume only one Carpenter is available and two Electricians are available. Given your resource schedule, compute the early, late, and slack times for your project. Which activities are now critical? What is the project duration now? Show ALL of your working to get the points (15 pts). 2 4 C E 0 1 4 3 6 C C Plan 3 3 5 2 C 2-E 5 Develop a loading schedule for each resource below.

There are three machines available to the project. Activities 1 and 4 require one machine to complete while activities 2, 3, 5 and 6 require two machines. Develop a resource- constrained schedule in the loading chart that follows. Use the parallel method and heuristics given. Be sure to update each period. Record the early start (ES), late finish (LF) and slack (SL) for the new schedule.
