Application of fuzzy decision making to the smoking problem

People often fall into a state of waver. A smoker knows ”in the head” that smoking harms his health, but fells a desire to smoke in order to compose himself ”at heart”. In case of an ”observation” (say: illness), a waver gradually sets on – whether to smoke or not. This process can be described as having two states of nature (”in the head” and ”at heart”), one of which is hidden, and only gradually comes to the surface, which leads to an apparent conflict. In this paper, we propose a model for this situation and the respective decision making and a way to solve the resulting problem, using the precepts of the fuzzy set theory.
