Rationality and Subjectivity in Preliminary Analysis of Acquisition Options of Technical Systems

Modeling the acquisition decision and, consequently, managing the capabilities of technical systems involves multiple options that need to be optimized first, based on universal constraints such as time, quality, cost, etc. The criterion of use (private or institutional), according to which analyzes can evolve differently, is also important. Regardless of the way in which these considerations are taken, there is always a difference of approach given by the quantitative and / or qualitative tools used but also by biases, heuristics and mindsets. The article analyzes succinctly, on an example of calculation (based on a matrix used in the theory of decision to evaluate the different alternatives made available, when we have a basic model to be referred to), the universe of these analytical modalities, underlining the idea of making analyzes using a maximum level of objectivity and minimizing as much as possible subjectivism. It has been chosen as a way of applying the field of procurement of technical systems with the possibility of highlighting as many aspects as possible on the decisional criteria. Critical analysis of the robustness of the choices made by the human factor as a rational decision-maker is presented, as it is seen in the classical economic theory, but taking into account the limitations highlighted by modern theories in the fields of psychology and information theory
