1.1-Queueing Models Involving Nonexponential Distributions 1. Consider the M/G/1 model with a = 0.2 and u = u = 0.25. A. Use the Excel template for this model (or hand calculations) to find the main measures of performanceL, Lq, W, Wq-for each of the following values of o: 4, 3, 2, 1,0 B. What is the ratio of Lq with o = 4 to Lq with o=0? What does this say about the importance of reducing the variability of the service times? C. Calculate the reduction in Lq when o is reduced from 4 to 3, from 3 to 2, from 2 to 1, and from 1 to 0. Which is the largest reduction? Which is the smallest? D. Use trial and error with the template to see approximately how much u would need to be increased with o = 4 to achieve the same Lq as with u = 0.25 and o=0
