Consider the project network pictured in Figure 10–22. Activity times, measured in days, are shown in parentheses next to each activity label.

a. Determine the earliest and the latest starting and finishing times for all activities. Draw a Gantt chart based on earliest starting times, but indicate activity slack where appropriate. How many days are required to complete the project?

b. A single critical piece of equipment is required in order to complete the following activities: A, B, C, D, G, and H. Determine a feasible schedule for the project assuming that none of these activities can be done simultaneously.

c. Two resources, R1 and R2, are used for each activity. Assume that these are both consumable resources with daily requirements as follows:
Daily Daily Requirement Requirement Activity of R1 of R2 A 4 0 B 8 6 C 10 9 D 18 4 E 12 3 F 5 12 G 3 2 H 0 6 Determine resource loading profiles based on the schedule found in part (b).

d. Based on the results of part (c), determine the cumulative amounts of resources R1 and R2 consumed if the schedule found in part

(b) is used.
