Abstract

This chapter introduces the Paraconsistent Decision-Making Method (PDM) based on Paraconsistent Annotated Evidential Logic Eτ, an alternative to classical logic and detracting from the principle of non-contradiction, that is, accept this principle without becoming trivial. In addition, an application example is presented in viability analysis, along with a comparative study of this method with the Statistical Method of Decision-Making and the referenced bibliography. In the application example, it analyzes the viability of launching a new product, examining carefully the situation of influencing factors with actual conditions of the consumer market. Comparing the PDM with the Statistical Method of Decision- Making (SMD) shows the compatibility of the two methods and consistency of the results obtained by both. Lastly, the bibliography used as reference as well as supplementary resources for consulting and research are presented.
