Most analytic and computer simulation models of the Navy's
CONREP phase of underway replenishment operations have assumed exponentially
distributed service times for two reasons: (1) lack of
better estimate of the true distribution, and (2) such an assumption
leads to more tractable mathematical solutions. By analyzing several different combinations of replenishment
vessels and combatant ships, it is demonstrated through goodness-offit
tests that gamma distributions whose parameters can be estimated
from actual operational data are more precise estimates of the actual
underlying CONREP service time distributions. Furthermore, it is shown
that the distribution can be made Erlang by minor adjustments to the
parameter estimates of the gamma distribution. Such a procedure might
be desirable for analytical models employing Laplace transforms. The data is subjected to linear regression techniques in an
effort to develop meaningful and accurate functional relationships
between service time and customer needs. The results indicate that
the standard error of the estimating relationships would be too large
to be of any practical use in planning an underway replenishment
operation.
