Section A (Questions 1 ~ 4): In Alice’s Wonderland, there are six different seasons: Fall (F), Winter (W), Spring (Sp), Summer (Su), Bitter Cold (B), and Golden Sunshine (G). The seasons do not follow any particular order, instead, at the beginning of each day the Head Wizard assigns the season for the day, according to the following Markov chain model:    Thus, for example, if it is Fall one day, then there is 1/6 probability that it will be Winter the next day (note that it is possible to have the same season again the next day).   

In class, we learned how to use QueueingTool.xls. We want to use an MGc model for station A which requires four parameters: lambda, mu, c, and sigma2. Given that lambda is entered as an hourly rate, enter the values of mu and sigma2.  mu = [b]; sigma2 = [d].

Using the stationary distribution, calculate the probability that a request of group size 2 is rejected.   

The steeply upward sloping yield curve in the figure above indicates that
