In this paper, we provide an easy method to obtain thedistribution of busy period for self-service queue with feedback. Usingprobability generating function we obtain the probability that there are nunits in the system at time t , pn ( t ) and the pr

In this paper we develop the confidence intervals for estimatingthe expected value of the units in the system and the maximumlikelihood estimates of the parameters are derived for truncated single -channel Markovian queue with balking, reneging and r

In this paper, we present an economic order quantity (EOQ) with both demand-dependent unit cost and restrictions. An analytical solution of the EQO is derived using a recent and simple method, which isthe geometric programming approach. The EOQ inven

In this paper we provide a simple method to determine the inventory policy of multiple items having varying holding cost using a geometric programming approach. The varying holding cost is considered to be a continuous function of the order quantity.
