summary In this paper, we investigate a methodological issue associated with the use of decision tables (DTs). In particular, a predominant problem concerns the categorization of the condition and action states in a DT. This categorization is assumed to exhibit a discrete (or crisp) character. Although sharply defined discrete categorizations imply an. accurate and precise decision-making, in many real time problems it proves to be a too stringent and severe assumption to impose on the choice maker. In order to solve this problem, we will enhance the DT formalism to incorporate elements from the theory of fuzzy sets. The construction of a fuzzy decision table (FDT) is explained in a step-by-step manner and illustrated by means of a brief example in the field of location theory. The paper concludes with an assessment of how to use and consult a FDT.
