a) What is the project completion date?

Based on the given information regarding the activities for the project, the project length =

_________weeks.

Part 3

b) What is the total cost required for completing this project on normal time?

The total cost required for completing this project on normal time = ____________

c) If you wish to reduce the time required to complete this project by 1 week, which activity should be crashed, and how much will this increase the total cost?

The critical path with the longest length through the project is

_______________

.

Part 5

To speed up the project at the least additional cost, first crash the activity that has the lowest crash cost per week. Determine the crash cost per week for each activity on the critical path.

For activity A, the per week crashing cost =

(Enter your response as a whole number.)

Part 6

For activity D, the per week crashing cost =

(Enter your response as a whole number.)

Part 7

For activity G, the per week crashing cost =

number.)

Part 8

For reducing the duration of the project by one week, the activity that should be crashed first is activity

Part 10

d) What is the maximum time that can be crashed?

Part 11

Path A - D - G is still critical. Of these critical activities, activity D has the lowest crash cost per week of

$70.

Therefore, crash activity D by 3 additional weeks to reduce the project completion time to

12

weeks.

Part 12

Note that activity D cannot be crashed any further, since it has reached its crash limit of

4 weeks.

Part 13

What is(are) the critical path(s) after crashing activity D down to

4 weeks? choose

A.

Both A - D - G and C - F are critical.

B.

Both A - D - G and B - E - G are critical.

.

C.

B - E - G is critical.

D.

A - D - G is still critical.

Part 14

Hence, any further crashing must be done to both critical paths.

Part 15

Determine the crash cost per week for activities on path B - E - G.

For activity B, the per week crashing cost = __________(Enter

number.)

Part 16

For activity E, the per week crashing cost =

(Enter your response as a whole

number.)

Part 17

For activity G, the per week crashing cost =

(Enter

your response as a whole

number.)

Part 18

On each of these critical paths, identify one activity that can still be crashed. Also the total cost of crashing the project should be the smallest. Note that activity

__________

is common to both paths. That is, by crashing this activity, we will simultaneously reduce the completion time of both paths, which yields the smallest total cost.

Part 19

Therefore, crash activity G by

______weeks.

(Enter your response as a whole

umber.)

Part 20

Activity A can still be crashed by 1 week. On path B - E - G, crash activity

______

by 1 week.

Part 21

Note that the project cannot be crashed any further, since all activities on path A - D - G have reached its crash limit. The maximum weeks by which the project can be reduced by crashing =

____________

weeks.

Part 22

How much would costs increase?

Total cost of crashing the project to minimum (or maximum weeks possible) =

D's crash cost + G's crash cost + A's crash cost + E's crash cost =
