(a) Construct an activity on node precedence diagram for the project described in Table 1 below. Determine the earliest start, earliest finish, latest start, latest finish times for each activity. (b) Calculate the total float for each activity and identify the critical path and the minimum project duration. (c) Prepare a Gantt Chart with a horizontal scale of (10mm=1 month) and show each activity starting at its earliest possible start time and its associated total float. (d) From the Gantt Chart construct a resource requirement profile with a vertical scale of (10mm=1 resource) and determine the maximum number of resources required if all activities start at their earliest start times. (e) Draw up a priority table of activities by Early Start and Total Float and determine the effect on the finish date if the maximum number of resources available is five
