Q. A competitor of Kozar International, Inc. has begun marketing a new instant-developing film project. Kozar has had a similar product under study in its R&D department but has not yet been able to begin production. Because of competitor's action, top managers have asked for a speed up of R&D activities so that Kozar can produce and market instant film at earliest possible date. Predecessor information and activity time approximates in months are shown below.

Activity Immediate Predecessors Optimistic Time Most Probable Time Pessimistic Time
A - 1 1.5 5
B A 3 4 5
C A 1 2 3
D B,C 3.5 5 6.5
E B 4 5 12
F D,E 6.5 7.5 11.5
G F 5 9 13

a. Draw AOA project ne2rk.

b. For each activity, Compute mean and variance of activity duration time.

c. Using mean activity times conduct a CPM analysis and develop an activity schedule for this
Project using early and late start and finish times, compute activity slack time and define critical activities.

d. Illustrate what is expected (i.e. mean) project completion time? Standard deviation of completion time?

e. Illustrate what is probability project will be completed in time for Kozar to begin marketing new product within 24 months?
