APPLICATION OF A METHOD TO ASSIST MULTI-CRITERIA DECISION MAKING IN THE RANKING OF AREAS FOR THE IMPLEMENTATION OF THE FIBER OPTIC NETWORK
In this work, we aimed to create an ordinal qualitative variable related to the sales perception of a given region and introduce this variable in a new model of decision-making support for the choice of new investment areas for the construction of optical fibre networks. For this purpose, we used data provided by one of the largest telecommunications companies in Brazil, referring to the criteria it considers for choosing the constructive order. As a methodology, we used the Analytic Hierarchy Process (AHP) with ratings to obtain an easily replicable model where the problem of decision-making could be seen and considered quantitatively and qualitatively. In the analysis, it was possible to identify that despite the relevance of quantitative data, primarily considered by the company, when considering the qualitative criterion in the model, the result obtained showed us the importance of considering all criteria simultaneously. We defend the relevance of the method as it allows the company to focus the team's efforts on decision-making on issues other than the divergences between numbers and qualitative knowledge.
