On dynamic oligopoly motivated by fuzzy concepts

A dynamic oligopoly model motivated by fuzzy concepts is given. Its steady state and stability and the bounds of its basin of attraction are studied. Delay (memory) is then introduced. Stability of chaos for delayed systems is discussed. A refinement for a fuzzy multiobjective optimization is given and it is shown that the set of refined solutions is Pareto optimal. Oligopoly is then reformulated using Smaleʹs game which is more realistic than ordinary games since it takes memory into consideration.
