... ANTITHETIC RANDOM VARIABLES To motivate the use of common and antithetic random variables in simulation, consider the following simple example Let X and Y be random variables with known cdfs, F and ... to the finite-horizon simulation and then calculates the point estimator and the confidence interval for C via (4.19) and (4.7), respectively, exactly as in the batch means approach Note that the ... Sample paths for the two inventory processes Let D , and A, be the size of the i-th demand and the length of the i-th interdemand time, respectively We assume that both { D,} and { A , } are iid...
