Construction of a small two-story house involves the tasks listed in the following table.

The table also shows the estimated duration of each task in days and the tasks that must completed before it can begin.

(a) Construct the corresponding CPM project network 9.30 .

(b) Number activity nodes in your project network so that every arc 1i, j2 has i 6 j.

(c) Use CPM scheduling Algorithm 9E with your activity numbering to compute early start times for each activity and an early finish time for the entire project.

(d) Use d[k] labels of your scheduling computations to identify the activities along a critical path from project start to finish.

(e) Compute late start times for each activity assuming that construction must be complete in 35 days, and combine with part

(c) to determine schedule slacks.
