Improvements to Huff model probability of visiting an establishment
Section: Business, Entrepreneurship and economy
To determine the likelihood of a consumer to visit a facility
in particular, Huff followed the axiom of choice proposed by Luce (1959). The company seeks challenging a system that improves the results of this axiom
which suggests that the probability that a consumer visit a particular store (Pij) is
equal to the ratio between the utility of that store (Uij) by the sum of utilities of all
stores considered by the consumer
