Support and Guidance to Practitioners by Simulation of Questions Formulated by Readers and Detailed Answers and Examples

This chapter incorporates innovation in science and technical books, at least in the MCDM area, since it simulates readers addressing the author with questions of varied nature related to situations that may be present in decision-making when modelling a problem. There are 101 questions and doubts distributed over eleven main topics, covering the whole spectrum of the decision-making scene. Each question, concern, or interest is thoroughly addressed normally in three parts. First, explaining it, second, posing an example, and third, by an analysis. When corresponding, references to the theoretical part of the book, that is, to the eleven precedent chapters, are suggested. Thus, the reader has a complete theoretical and practical explanation of his/her question that blends two aspects: an instruction manual and personal guidance or tuition. The chapter contains 12 graphics and 22 tables, which is a measure of the depth the different questions are answered. It has an only purpose: to answer people’s concerns, for instance, How can I model this problem? Which is the best procedure for… ..? When to use Entropy and how to calculate it? Is there an example where I can see how to proceed?
