The least-cost allocation of snow-producing zones among available elimination sites is formulated as a classical transportation problem. The assumptions underlying this formulation, which proves useful in the study of large-scale allocation problems, are discussed. A numerical example is solved and used to illustrate two post-optimal analysis questions. One assesses the influence of a reduction in the unit transportation cost on the optimal solution; the results are used to determine solutions slightly more expensive than the optimal allocation for studying possible trade-offs. The other defines areas where it would be economically advantageous to locate new elimination sites.
