Please answers Question 1 untill 3.

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 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.

CASE STUDY 1 Sout western University (SW) a large state college in Stephenvile, Texas, 30 miles Southwest of the Dalas/Fort Worth metroplex, enrols 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 fal 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 football rankings. To bolster its chances of reaching the elusive and long desired number one ranking. In 2006, SWU hired the legendary Phil Flamm as its head coach One of Flamm's demands on joining SWU had been a new stadium Win attendance increasing, SWU administrators began to face the issue head-on. After 6 months of study, much political arm wrestling, and some serious financial analysis, Dr. Joel Wisner, president of SWU, had reached a decisions to expand the capacity at its on-campus stadium. Adding thousands of seats, including dozens of luxury skyboxes would not please everyone The influential Flamm had argued the need for a firs class stadium, one with built-in dormitory rooms for his players and a palatial office appropriate for the coach of a future NCAA champion team. But the decision was made, and everyone, including the coach, would learn to ive The job now was to get construction going immediately after the 2012 season ended This would allow exactly 270 days until the 2013 season opening game. The contractor, Hill Construction (Bob Hil being an alumnus of course), signed his contract Bob Hill looked at the tasks his engineers had outlined and looked President Wisner in the eye. I guarantee the team will be able to take the field on schedule next year," he said with sense of confidence. "I sure hope so," replied Wisner. "The contract penalty of $10,000 per day for running late is nothing compared to what Coach Flamm will do to you if our opening game with Penn State is delayed or cancelled." Hill, sweating slightly, did not need to respond in football-crazy Texas, Hil Construction would be mud if the 270-day target were missed Back in his office, Hil again reviewed the data (see Table 1) and noted that optimistic time estimates can be used as crash times. He then gathered his foremen "Foks, if we're not 75% sure we'll finish this stadium in less than 270 days. I want this project crashed! Give me the cost figures for a target date of 250 days - also for 240 days. I want to be early, not just on time! Discussion Questions 1.
