In the stochastic assignment model there is no clear choice of functional. Six different criteria for the stochastic assignment model are discussed and one is suggested as best.

It is shown that the stochastic properties of this model completely depend on the calibration parameter. After giving the searching method of an `efficient paths' set, a modified combined algorithm ...

This example departs somewhat from the emphasis of previous ones. Typically, linear programming models are large, have considerable structure, and are solved with some regularity. Some form of ...
