36. In Chapter 8, Figure 8.6 shows a simplified project network for buildiag a house, as follo'ns:
There are four paths througfu rhis networlc
PathA: l-2-W-7 Path B: l-2-*-*-7 PathC: l--24-7 Path D: L-2-+-5-+-7
The time parameters (in weeks) defiring a triangular probahility distribution for each aaivity are provided as follorrs:
Time Parameters
Activitf Minimum Likeliest Maximum
Using Crystal Ball, sirnulate ach path in the network and identiff the longest path (i.e., the afticaf path). Observing the sirnulation run frequency chart for path A, determine the probability that this pathwill exceed the criticat path time.What does this tell you about the simulation results for aproiect networkversus an analytical result?

t*con") T*o Banks was standing in line next to Robin Cole at Klecko's ) Crllpy Center, waiting to use one of the copy machines.'Gee, Robin, I hate this," he said-*We have to drive all the way over here
from Southgate and then wait in line to use these copiy mactines. I hate wasting time Iike this."
"I knorr what you meao," said Robin- *Aud look who's here. A
lot of these students are from Southgate Apartments or one of the other apartmeots near us It seems as though it would be more logical if lftcko's would move its operation over to us, instead of all of us coming over here."
