Interactive tools, in English and Spanish, have been produced to facilitate the teaching. One that stands out is the one created to facilitate the teaching of the Preference Ranking Organization METHod for Enrichment Evaluations (PROMETHEE). This article presents some comments on the process of creating this software, and to illustrate it will use the case of PROMETHEE. Hence, the objective of this work is to present the process of creating a teaching tool, specifically that of the PROMETHEE case. The methodology to be used to complete this work is the integrated-adaptable methodology for the development of decision support system.

This work will focus on making a review of one of the techniques to establish hierarchies between alternatives, which appears very frequently, although erroneously, in the literature dedicated to multicriteria methods. It is about scrutinizing within the bowels of analytical hierarchical processes (AHP). It will be noted that it will not be necessary to make an exhaustive review to discover the great weaknesses that are present under this much referenced technique, faults so obvious that it is difficult to understand how this method has been used so often. These failures start from their foundations, their axioms, from a misinterpretation of mathematical statements, and especially, from an inappropriate use of the tool. From all the above, the objective of this work is to analyze the fundamental premises of analytical hierarchical processes and demonstrate that they are not only techniques that have very obvious flaws but are also used erroneously in decision making for which they are not at all appropriate.

In this work, through a logistic model, several aspects of organizations are related, such as ethics, Safety & Security and innovation. To do this, the Ethical Legal Consultant of the Logistic Model Based on Positions will be used. Given the close relationship that logistics has with almost all aspects of the organization, the objective of this work arises: Generate some guidelines to improve the ethical aspects of an organization, following guidelines offered by the Legal Ethical Consultant of the Logistics Model Based on Positions. To achieve this objective, the Integrated-Adaptable Methodology for the development of Decision Support System will be followed, which, it has been demonstrated, adapts to this type of research.

In this work, within the business world, two fields of great social interest are related. In particular, it will talk about corporate Safety & Security (S&S) and Corporate Social Responsibility (CSR). The importance of S&S in a service company will be analyzed, while some of the actions that these companies can take to increase their CSR will be studied. Specifically, the study will focus on trying to offer some recommendations, to help ensure that train travel is safer and more enjoyable for passengers who suffer from a disability. From what has been said previously, the objective of this work can be stated as: present some actions, so that the trip by train, of passengers with some disability, is safer and more pleasant. To achieve this objective and the secondary objectives that may be generated, the Integrated-Adaptable Methodology for the development of Decision Support System will be followed, which, it has been shown, is very useful in investigations similar to this.
