Avaliação da gestão energética de uma indústria automobilística e proposição de melhoria através de elementos da indústria 4.0: uma abordagem multicritério

Abstract

Given the current context of high electricity prices, environmental concerns and the need to be increasingly efficient to be competitive in the market, industries face the challenge of reducing their energy consumption in a sustainable way. This great challenge with the need to automate processes in an integrated way, requires the company to be precise when choosing which technologies to invest. The work in question evaluates which are the best technologies of industry 4.0 to be applied for the industry in question to make their energy management in the most effective way. The scope of this work proposes the elaboration of an evaluation model based on multi criteria evaluation methods, which helped in the analysis of the diagnostic phase through the AHP (Analytic Hierarchy Process) and in the evaluation and prioritization phase of technologies through PROMETHEE. The results show that the automotive industry where the study was conducted is at an advanced level when it comes to operation and process, but at a lower level of maturity in terms of measurement and strategy. From this, improvements were proposed using the technological enablers with the greatest positive impact on the company, ystem Integration, Big Data & Analytics and Internet of Things.
