Land-use criticality measures based on an interior point in a convex polytope

A recently proposed approach to the problem of identifying critical resource allocations requires that a unique central point be found within the feasible region defined by a set of linear inequalities. Although two procedures for identifying such a point have been proposed, each has significant shortcomings. The concept of critical allocations is reviewed, with illustrations of the limitations in the proposed procedures, and a method of overcoming the noted shortcomings is presented.
