Exam Two Study Material ISYE 6644 | Study Answer Collection ISYE 6644 - final EXAM 2 - answer - Exam Coverage Exam coverage for the ISYE 6644 - Final Exam 2 includes advanced simulation concepts, probability modeling, statistical analysis, and computational techniques used to analyze discrete-event dynamic systems. It focuses on the design and evaluation of simulation models, random-number and random-variate generation, input modeling, output analysis, and statistical inference for simulation studies. The exam also emphasizes selecting appropriate analytical methods and interpreting simulation results for engineering and operational decision-making. An entity can be scheduled to visit the same resource twice, with different service time distributions on the two visits! - answer - TRUE Arena has a built-in Input Analyzer tool that allows for the fitting of certain distributions to data. - answer - TRUE The Kolmogorov-Smirnov test can be used both to see (i) if data seem to fit to a particular hypothesized distribution and (ii) if the data are independent. - answer - FALSE. (It's just a goodness-of-fit test.) If you are using a ranking-and-selection procedure and two competitors happen to fall within the indifference-zone, then you don't really care too much which one you end up selecting. - answer - TRUE. That's why it's called the IZ! In our Arena Call Center example, it was possible for entities to be left in the system when it shut down at 7:00 p.m. (even though we stopped allowing customers to enter the system at 6:00 p.m.). - answer - TRUE — because of the small chance that a callback will occur. Welch's method is a graphical technique to estimate truncation (initialization bias) points for steady-state simulation. - answer - TRUE If f(x, y) = cxy for all 0 x 1 and 1 y 2, where c is whatever value makes this thing integrate to 1, then X and Y are independent random variables - answer - TRUE. (Because f(x, y) = a(x)b(y) factors nicely, and there are no funny limits.) TRUE or FALSE? Sequential ranking-and-selection procedures are designed to stop early if one alternative seems to be way out in front of the others. - answer - TRUE Suppose, when designing a ranking-and-selection procedure, you have decided to increase the desired probability of correct selection compared to a previous run of the procedure. What can you expect? (a) Sample sizes that are about the same (b) Larger sample sizes (c) Somewhat lower achieved Pr(CS) (d) A larger indifference zone (e) Lower confidence in your selection - answer - b In Arena, you can use a single DECIDE module to route customers to that one of four servers having the smallest queue. - answer - TRUE TRUE or FALSE? In Arena, you can use the expression EXPO(3) to generate exponential interarrival times having a mean of 1/3. - answer - FALSE. The mean of an EXPO(3) is 3. TRUE or FALSE? In Arena, an alternative expression to generate exponential interarrival times having a mean of 1/3 is -(1/3)*LN(UNIF(0,1)) - answer - TRUE. This is the Inverse Transform Method to generate an observation coming from Exp(λ = 3). TRUE or FALSE? In Arena, it is possible to set the maximum capacity of a queue from within a SEIZE module. - answer - FALSE. It is only possible to set a maximum queue capacity from within a QUEUE block found in the Blocks template. 2 TRUE or FALSE? In Arena, the expression NORM(-1,2)+NORM(3,2) has the same distribution as the expression NORM(2,4) - answer - FALSE. The above expression evaluates to NORM(2,√ 8) since, in Arena, NORM(x,2) corresponds to a normal random variate with a mean of x and a standard deviation of 2; so the variance of this random variable is 22 = 4. TRUE or FALSE? In Arena, it is only possible to use one resource at a time in a PROCESS module. - answer - FALSE TRUE or FALSE? In Arena, once an entity is defined, it is not possible to change the priority in which it gets processed by a resource. - answer - FALSE TRUE or FALSE? In Aren
