Employing the supplementary variable and embedded Markov chain techniques, we derive the steady state system length distributions at different time epochs. Based on the various system length distributions, the blocking probability, probability mass function of sojourn time and other performance measures along with some numerical examples are discussed. Then, we use the parabolic method to search the optimum value of the service rate in working vacation period under a given cost structure. rv:
