## Question:

3 Before a new product can be introduced, the activities in Table 40 must be completed (all times are in weeks).

a Draw the project diagram.

b Determine all critical paths and critical activities.

c Determine the total float and free float for each activity.

d Set up an LP that can be used to determine the critical path.

e Formulate an MCNFP that can be used to find the critical path.

f It is now 12 weeks before Christmas. What is the probability that the product will be in the stores before Christmas?

g The duration of each activity can be reduced by up to 2 weeks at the following cost per week: A, $80; B, $60; C, $30; D, $60; E, $40; F, $30; G, $20. Assuming that the duration of each activity is known with certainty, formulate an LP that will minimize the cost of getting the product into the stores by Christmas.
