Software development is an inherently risky and uncertain process. For example, there are many examples of software that couldn't be "finished" by the scheduled release date-bugs still remained and features weren't ready. (Many people believe this was the case with Office 2007.) How might you simulate the development of a software product? What random inputs would be required? Which outputs would be of interest? Which measures of the probability distributions of these outputs would be most important?
An article in Communications of the ACM (Vol. 30, No. 5, 1987) studied different algorithms for...... ... data are in the table at the bottom of the page. (a) Do the algorithms differ in their mean cost estimation accuracy? Use a = 0.05.(b) Analyze the residuals from this experiment.(c) Which...
Software Development Specialists (SDS) is involved with developing software for customers in the...... ... involved for team A. How long will it take for team A to complete their programming assignment? What would happen if activity 5, writing detailed program specifications, had larger time...
Continuing the preceding problem, suppose that another key uncertain input is the development...... ... will be from 6 to 10 months. They believe that8 months is twice as likely as either 7 months or 9 months and that either of these latter possibilities is three times as likely as either 6 months...
Pettit Corporation reported the following operating results for two consecutive years. Requireda. Compute the percentage changes in Pettit Corporation\'s income statement components between the two years.b. Comment on apparent trends revealed by the percentage changes computed in Requirement α.
Consider the airplane and flight conditions given in Prob. 5.4. The span efficiency factor e for the complete airplane is generally much less than that for the finite wing alone. Assume e = 0.64. Calculate the induced drag for the airplane in Prob. 5.4.

1. How would you describe the founding team of Fenton, Hoffer, and Le Tuan? Is it a balanced team? What does each member bring to the business? Can you see gaps in their skills and capabilities that should be adjusted for in some way? 2. What is the form of organization that Fenton, Hoffer, and Le...
Suppose you are a financial analyst and your company runs many simulation models to estimate the profitability of its projects. If you had to choose just two measures of the distribution of any important output such as net profit to report, which two would you choose? Why? What information would be...
Health care is continually in the news. Can (or should) simulation be used to help solve, or at least study, some of the difficult problems associated with health care? Provide at least two examples where simulation might be useful.
(a) Prove that if |det T| > 1 then the iterative system u(k+l) = T u(k) is unstable. (b) If |det T| < 1 is the system necessarily asymptotically stable? Prove or give a counterexample.
