Answer all parts, a, b, c, and d. Make sure to include Gantt Chart

.22 Space Module Assembly. An aerospace company has received a contract from NASA for the final assembly of a space module for an upcoming mission. A team of engineers has determined the activities, precedence constraints, and time estimates as given in Table 9.19. a. Draw the AOA network for this project. (Hint: You should have 10 events and two dummy activities.) b. Calculate total slacks and free slacks, and interpret their meaning. c. Determine the critical path and interpret its meaning. d. Construct a Gantt chart and identify scheduling flexibilities. .22 Space Module Assembly.
