Description:
This paper presents and compares two location-allocation models for assigning a limited number of airtanker groups among a larger number of potential bases. Model I selects bases to maximize the number of fires (weighted by value at risk) within range of an attack base. Model II trades off this goal with the minimization of mean fire to base distance. The models were applied to 1971–1974 fire totals in Alberta for three 10-day periods. As the number of airtanker groups was increased from one to the maximum, the performance of each model increased with smoothly diminishing returns. For all periods and at most levels of resource investment, the maximum coverage model served only a few more fires than did the other, sacrificing considerable distance in doing so. In view of the limitations of these simple models, a more comprehensive model was developed and discussed.
