Abstract
In such facilities as office buildings and factories where the number of customers is restricted, it is necessary for determining the size of the canteen, to estimate the number of customers who arrive at a time in the lunch time period. Investigations of congestions in these facilities are made and the tendencies of arrival distributions are surveyed. Several differences are observed in congestion at initial period in the case of between office building and factories. Some special consideration may be necessary on these queueing which deal with congestion dependent of a certain time (i.e. noon). a. Approximate solutions of L_q are studied, assuming M/E_K/S(0) to be M/M/1(∞), by means of the transient non-equilibrium theory. b. A method of determining the number of items in the system is studied assuming that the arrivals of customers are normally distributed with maximum arrival at the noon.
