Compute the earliest starting time and earliest finishing time for each activity in the diagram shown in Figure 17.5.
For the activity on arrow network information given below (activity durations are givenin the table under part b):
a. Compute the earliest event occurrence time (TEj), the latest allowable eventoccurrence time (TLj), and the event slack (ESj) for all nodes/events.
b. Compute the four schedule dates (ESDij, EFDij, LSDij, LFDij) and the floats(TFij, FFij) for all activities.
For the network schedule shown below, which statement is true?
a. This is an example of the Activity-on-Node (AON) method of network diagramming.b. Activity F can start without waiting for the completion of Activity B.c. Activity B can occur concurrently with Activity D.d. To simplify the network, Activities F and G can be combined without changing the logic.

Final decision 20 The office has three employees, activities A, B and C are combined together and assigned to two employees, while the other employee is responsible for the last activity D. Under this setting, what would be the maximum number of loan applications the office can process per day? Numbers only, keep three decimals if not exact, either round up or down is okarrow_forward. With activities B and C as immediate predecessors, the earliest start time for activity H must be equal to the largest of the earliest finish times for activities B and C. Thus, with EF = 6 for activity B and EF = 9 for activity C, 9 is the earliest start time for activity H (ES = 9). And with an activity time of 12 as shown in the node for activity H, what is the earliest finish time?arrow_forward
