Reconsider Prob. 22.6-3.

You now wish to begin the analysis by performing a short simulation by hand and then applying the regenerative method of statistical analysis when possible.

R

(a) Starting with four new tubes, simulate the operation of the two alternative policies for 5,000 hours of simulated time.

Obtain the needed uniform random numbers as instructed at the beginning of the Problems section.

(b) Use the data from part

(a) to make a preliminary comparison of the two alternatives on a cost basis.

(c) For the proposed policy, describe an appropriate regeneration point for defining cycles that will permit applying the regenerative method of statistical analysis. Explain why the regenerative method cannot be applied to the current policy.

(d) For the proposed policy, use the regenerative method to obtain a point estimate and 95 percent confidence interval for the steadystate expected cost per hour from the data obtained in part (a).

(e) Write a computer simulation program for the two alternative policies. Then repeat parts (a), (b), and

(d) on the computer, with 100 cycles for the proposed policy and 55,000 hours of simulated time (including a warm-up period of 5,000 hours)

for the current policy.
