Facility location-allocation models are used in a widespread variety of applications to determine the number of required facility along with the relevant allocation process. In this paper, a new mathematical model for the capacitated multi-facility location-allocation problem with probabilistic customer's locations and fuzzy customer’s demands under the Hurwicz criterion is proposed. Thi...

In this paper, a location allocation (LA) problem in construction and demolition (C&D) waste management (WM) is studied. A bi-level model for this problem under a fuzzy random environment is presented where the upper level is the governments who sets up the processing centers, and the lower level are the administrators of different construction projects who control C&D waste and the after treat...

We consider a market where consumers mix goods offered by two firms differentiated a la Hotelling, and show how tariff structures affect consumers, profits, and location decisions. As compared to linear pricing, when firms charge two-part tariffs they make higher profits while consumers are worse off. The resulting allocation is not efficient since firms choose extreme locations and too little ...
