What is the role of “slack” in the context of PERT and CPM?
What is the role of “slack” in the context of PERT and CPM?
Asks about the ethical issues.
Asks which type of organization may become permanent.
Given the amount of chemicals used, the labor cost, miscellanious expenses, and the percentage of which the chemical usage increases… find the percent that productivity has decreased.
Your numbers will vary.
This problem tells you that a project is being analyzed by PERT. Gives you activities, days and the project variance. Asks for the normal distribution probability of days to complete. Answers for both more than days and less than days.
Your numbers will vary.
Given a large data table of activities, slack, normal time, crash time, and crash cost, determine which activity would be the best for the crashing option to reduce the project by a week.
Your numbers will vary.
Given the optimistic, most likely, pessimistic values – as well as the standard deviation and expected durations… find the expected variance.
Your numbers will vary.
Given the early start time and the late start time.. find the true statement and slack.
Your numbers will vary.
Gives you the normal duration, shortened duration, and the added cost. Asks for the crash cost per period.
Your numbers will vary.
Given a table with X and Y numbers, develop a linear regression forecasting model, solving for the slope (b) of the line.
Your numbers will vary.
