Consider the following resource loading table. Assume that we cannot schedule more than eight (8) hours work during any day of the month.
a. Can you identify any days that involve resource conflicts?
b. How would you reconfigure the loading table to resolve these resource conflicts.

a. According to the resource loading table, the dates June 8, 9, and 10 are all overallocated (11 hours), as are June 16, 17, 18, and 19 (9 hours).
b. One solution for leveling the resource loading table is by taking advantage of slack time available in activities D and G and moving these activities later in the schedule to correspond with their late finish dates (see the resource loading table below).

1. Construct the project activity network using AON methodology.
2. Identify the critical path and other paths through the network.
3. Create a Time-Phased Resource Loading Table for this project, identifying the activity early start and late finish points
4. Assume that the maximum resource hours per week available for the project are eight. Can you identify any weeks with resource over commitments?
5. Resource level the loading table. Identify the activity that can be rescheduled and reconfigure the table to show this reallocation.
