Problem 1: Given the information provided below (predecessors,
normal time, normal cost, crash time and crash cost for an
eight-activity (a to h) project) answer the questions (a) through
(e) using this template. Activity Predecessor Normal Time Normal
Cost Crash Time Crash Cost Crash Cost/Day a – 5 $50 3 $150 b – 4 40
2 200 c b 7 70 6 160 d a, c 2 20 1 50 e a, c 3 30 – – f b 8 80 5

diagram. Identify the critical path of the network, the time, and
cost of the normal level of activity for the project: • The
critical path is: __________________ • The project duration:
___________ • The project cost is: _____________ (b). Calculate the
crash cost-per-day (all activities may be partially crashed). Enter
your response to question 1(b) in the table provided below Activity

d e f g h (c). Find the optimal way of getting an 18-day delivery
time. What is the projected cost? Once you’ve found the solution,
explain the results of your calculations. (d). Find the optimal way
of getting a 16-day delivery time. What is the project cost?
Explain your results. (e). Calculate the shortest delivery time for
the project. What is the cost?
