摘要：The general procedure for determining the fluctuation in different phases of a population in which the changes take place either as functions of time or some parameter of the population is considered in this paper. It is indicated that the solution for most of the queuing problems can be obtained as special cases of the above procedure. Following this, the exact solutions for stable or unstable condition arising for some simple situations have been obtained.
