Problems Markov Chains ) Given the following one-step transition matrix of a Markov chain, determine the classes of the Markov chain and whether they are recurrent.

Problems Markov Chains ) The leading brewery on the West Coast (A) has hired a TM specialist to analyze its market position. It is particularly concerned about its major competitor (B). The analyst believes that brand switching can be modeled as a Markov chain using 3 states, with states A and B representing customers drinking beer produced from the aforementioned breweries and state C representing all other brands. Data are taken monthly, and the analyst has constructed the following one-step transition probability matrix. A B C What are the steady-state market shares for the two major breweries?

Solutions Markov Chains ) A computer is inspected at the end of every hour. It is found to be either working (up) or failed (down). If the computer is found to be up, the probability of its remaining up for the next hour is It it is down, the computer is repaired, which may require more than one hour. Whenever, the computer is down (regardlewss of how long it has been down), the probability of its still being down 1 hour later is a.Construct the one-step transition probability matrix. b.Find the expected first passage time from i to j for all i, j.

Solutions Markov Chains ) A manufacturer has a machine that, when operational at the beginning of a day, has a probability of 0.1 of breaking down sometime during the day. When this happens, the repair is done the next day and completed at the end of that day. a. Formulate the evolution of the status of the machine as a 3 state Markov Chain. b.Fine the expected first passage times from i to j. c.Suppose the machine has gone 20 full days without a breakdown since the last repair was completed. How many days do we expect until the next breakdown/repair?
