Abstract

Currently, around the world, the concept of "Industry 4.0" is being inserted in the industrial sector, mainly due to the need to create "intelligent factories" that lead to the development of functional products with the lower cost of production and delivery, and higher quality. However, the insertion of this concept still needs to overcome some operational barriers because there are different technological realities in traditional manufacturing methods. In this context, this project aims to study the technological maturity of the wood industry, more specifically a sawmill, to look for ways for its transition to Industry 4.0. Thus, the present project aims to carry out research in a sawmill to the gathering of data in relation to: I) technical information about equipment that participating in all the productive subprocesses; II) unit costs associated with unexpected stoppages of productive processes and; III) technological and operational gaps that must be overcome so the company can be inserted in the context of Industry 4.0. As part of this project, we intend to identify the Processes Immunity Time (PIT) to electrical disturbances (voltage sags, power interruptions, etc.). In addition, this project aims to simulate the actual production process in a digital environment, i.e., to create a cyberphysical environment in which each equipment and the interconnection between the subprocesses (series, parallel or mixed) can be digitally represented. The purpose of this simulation is to estimate PIT values for different process failure conditions as a consequence of electrical disturbances during the electric power supply. Also, as part of this project, some technological solutions within the context of Industry 4.0 will propose that allow to improve the PIT value of each subprocess and maintain the continuity of the productive process in the sawmill. The solutions will be grouped according to the technical and budgetary limitations of the company.
