Final answer:
The question is about drawing an AON PERT diagram for a project involving multiple activities, using provided information on immediate predecessors and activity durations. It includes organizing the activities in sequence, plotting them, and connecting them to indicate dependencies
Step-by-step explanation:
The question involves creating an Activity-on-Node (AON) Program Evaluation and Review Technique (PERT) diagram for J.C. Howard's management team. This diagram is a visual representation of the activities involved in a project and the relationships between them. It's particularly useful in identifying the critical path, which is the sequence of activities that determine the shortest time in which a project can be completed.
To draw the AON PERT diagram, one would start by listing all the activities (A through I) and arranging them based on their immediate predecessors. For instance, Activity A would be the starting node as it has no predecessors. B and C would follow, linked from A. This process continues until all activities are connected as per their dependencies. The final step is to calculate the earliest and latest start/finish times for each activity to determine the critical path.
In this case, the student has provided a chart of activities with their respective predecessors and times. To complete the task, it's necessary to plot each activity in the sequence dictated by their prerequisites and then connect them accordingly with arrows that indicate the flow and dependencies between tasks. For each task, the duration time should be noted.
