This paper presents a decision model that uses empirical Bayesian estimation
to construct a server-dependent M/M/2/L queuing system. A Markovian queue with a
number of servers depending upon queue length with finite capacity is discussed. This
study uses the number of customers for initiating and turning off the second server as
decision variables to formulate the expected cost minimization model. In order to
conform to the reality, we first collect data of interarrival time and service time by
observing a queuing system, then apply the empirical Bayesian method to estimate its
traffic intensity. In this research, traffic intensity is used to represent the demand for
service facilities. The system initiates another server whenever the number of customers
in the system reaches a certain length N and removes the second server as soon as the
number of customers in system reduces to Q. Associating the costs with the opening of
the second server and the waiting cost of customers, a relationship is developed to obtain
the optimal value of N and Q to minimize cost. The mean number of customers in the
system and the queue length of customers are derived as the characteristic values of the
system. Model development and the implications of the data are discussed in detail.
Keywords:
Empirical Bayesian estimation, server-dependent queuing system, traffic intensity.
