Input: In the present paper we use principles of fuzzy logic to develop a general model representing several processes in a system’s operation characterized by a degree of vagueness and/or uncertainty. For this, the main stages of the corresponding process are represented as fuzzy subsets of a set of linguistic labels characterizing the system’s performance at each stage. We also introduce three alternative measures of a fuzzy system’s effectiveness connected to our general model. These measures include the system’s total possibilistic uncertainty, the Shannon’s entropy properly modified for use in a fuzzy environment and the “centroid” method in which the coordinates of the center of mass of the graph of the membership function involved provide an alternative measure of the system’s performance. The advantages and disadvantages of the above measures are discussed and a combined use of them is suggested for achieving a worthy of credit mathematical analysis of the corresponding situation. An application is also developed for the Mathematical Modelling process illustrating the use of our results in practice.
