# A Critical path problem

Activity Immediate

predecessors Activity Times (days) Estimated activity time Critical Path Activity

a m b

A - 3 3 3

B - 1 2 4

C B 3 4 5

D A 2 5 8

E A 3 5 7

F C, E 1 2 3

G F 5 6 7

1. Draw the network, calculate activity times and determine the critical path and project time.

2. Calculate the standard deviation for the project time.

3. Determine the probability that the project will take in excess of 18 days, less than 15 days.

4. If we wanted a 90% probability of completion by a given date, how many days would we use as our target?
