Os efeitos da Internet das Coisas (IoT) em linhas de montagens: estudos de caso na industria de autopeças

Abstract

With the advent of new technologies, there is a production systems evolution. The so- called Industry 4.0 (i4.0) brings the concept of Smart Factories applying advanced

systems of information technology (IT) and Internet of Things (IoT) aimed at increasing production. The IoT has a wide scope of application in the industrial area but there are no effects of its application on assembly lines, as well as research aimed at auto parts companies that use IoT technology to improve manufacturing operations. In this context, this paper focused on understand how auto parts companies are implementing IoT in assembly line operations and which are the effects of this implementation in performance indicators. For this, a bibliographic review is carried out to identify a research gap. Then, data from three auto parts factories are collected and analyzed, using the Case Studies methodology to analyses and compare the feasibility of the research. The results showed that the IoT can produce positive effects, mainly in the global efficiency index (OEE) of the auto parts assembly lines, reaching an increase of up to 10 percentage points in the period of 12 months. Research also showed that, one of the cases studied was adopted an IoT Framework and this case achieved higher performance, implemented more IoT technologies and demanded shorter execution period. In this way, this research can bring contributions both to Theory and to the Practice of Production Engineering and Operations Management, helping in a indirect way to increase the auto parts industry, benefiting the economy of the areas where the factories are installed.
