1. Develop a network drawing for Hill Construction and determine the critical path. How long is the project expected to take? 2. What is the probability of finishing in 270 days? 3. If it is necessary to crash to 250 or 240 days, how would Hill do so, and at what costs? As noted in the case, assume that optimistic time estimates can be used as crash times.

Southwestern University: (A)* Southwestern University (SWU), a large state college in Stephenville, Texas, 30 miles southwest of the Dallas/Fort Worth metroplex, enrolls close to 20,000 students. In a typical town gown relationship, the school is a dominant force in the small city, with more students during fall and spring than permanent residents. A longtime football powerhouse, SWU is a member of the Big Eleven conference and is usually in the top 20 in college foot- ball rankings. To bolster its chances of reaching the elusive and long-desired number one ranking, in 2009, SWU hired the leg- endary Phil Flamm as its head coach.
