ABSTRACT="This paper opens with a general review of some points in
congestion theory, and continues with a simplified account of the
pollaczek-khintchine ``equilibrium'' theory for the single-counter queue
fed by an input of the Poisson type and associated with a general
service-time distribution. It is pointed out that although the
stochastic process describing the fluctuations in queue-size is not (in
general) Markovian, it is possible to work instead",

ABSTRACT="For simple telephone systems with waiting facility expressions
are obtained for the first and second moment of the distributions of the
number of delayed calls and of the total time during which all lines are
occupied.  The non-randomness of delayed calls proves to have a much
greater influence than that of lost calls in the corresponding case
without waiting facility,",

ABSTRACT="The logic of estimating the parameters in evolutive processes
is considered with reference to a simple Poisson process and to the
process resulting from using a counter with non-zero resolving time. A
complete solution to the problem of estimating the parameter in a simple
birth process is followed by a partial solution of the problem of
estimating the two parameters in the simplest birth and death process.

ABSTRACT="This paper describes the determination of the first four
semi-invariants of the distribution of the average, over an arbitrary
time interval, of traffic carried by a telephone system with an infinite
number of trunks, during a period of statistical equilibrium. Both
finite and infinite number of independent call sources are considered,
and the distribution function of call holding times is left general.",
