Abstract
Interregional equilibrium in a fuzzy environment is investigated in this two-part series of papers. Problems involving a single fuzzy objective and a set of fuzzy constraints are analyzed within a fuzzy linear programming framework in the present part. Emphasis is placed on problem formulation and the derivation of an equilibrium solution. Theoretical properties of the solution, the associated duality arguments, and their spatial economic interpretations are scrutinized. A simple application is provided to substantiate the discussion. This first part of the two-part series is designed to provide a foundation for the multiobjective interregional equilibrium analysis to be discussed in the second part.
