Problem 1 The following is an activity-on-arrow

Problem 1 The following is an activity-on-arrow project network. Arrow labels list the normal activity time, minimum activity time after crashing, and cost of crashing per unit time, respectively. Duration is in days and cost is in dollars. - Determine the critical path(s) and minimum completion time at the minimum extra cost using crashing. - Determine the critical path and minimum completion time if you can only spend an extra $320. Problem 2 The following is an activity-on-arrow project network. Arrow labels list the normal activity time, minimum activity time after crashing, and cost of crashing per unit time, respectively. Duration is in days and cost is in dollars. - Determine the critical path(s) and minimum completion time at the minimum extra cost using crashing. - Determine the critical path and minimum completion time if you can only spend an extra $320
