A system is considered where ships of constant capacity sail from a port with a fixed interdeparture time. It is often assumed that units of cargo arrive at the port according to some well-known probability distribution. Usually, the Poisson distribution is assumed because it describes reasonably well the arrival process. This distribution corresponds to the case of random arrivals with a constant mean, which is close to most real situations. It cannot be assumed, however, that all units which have arrived at the port will be carried by a single ship. It is possible that, for some of the units, space will not be available on the present sailing; and so the cargo will have to wait until the next sailing. The problem is that it cannot be assumed that a unit of cargo will always wait until space is available. This unit might well be carried by another shipping company which offers a more convenient sailing schedule. This discussion is concerned with a mathematical model which can describe reasonably well the arrival pattern as well as the balking process encountered in this problem.
