Question $2(30\%)$ :

Draw an AON network that depicts the proper logic for the remodeling of a school. The

activities and their dependencies are listed in the table below.

Perform a critical path analysis to determine the minimal requirement for total project

duration, to identify the critical path, and to compute the values of ES$,$ EF$,$ LS$,$ LF$,$ TF$,$

FF for the activities.

Suppose the duration of Activity $E$ varies from $2$ days to $8$ days. Use the float times

derived from the above critical path analysis to determine the change in project

duration and the change in total floating time of Activity $F$ for each duration increase

of Activity $E.$
