William Smith, project manager for a Stinley Homes construction project needs to look at

alternatives to reduce the duration of a home construction project. Hereunder is a table

showing all project activities and their duration. He calculated the project duration to be $27$

months, at a normal cost of $$300$k$.$ Activity crash costs and duration data are provided by the

experts in the same activity table. The project manager has also calculated the normal indirect

costs to be $$300$k$,$ which could be reduced by $$25$k for each month reduction in project

duration
