Track: Production Planning and Management

Abstract

In this research, the indicators that influence the calculation of the overall equipment effectiveness (OEE) of a cutting line in a manufacturing company were analyzed. The main objective was to examine the main causes that directly affect the increase in the production capacity of the line. The data collection regarding task performance, daily production, amount of nonconforming product and compliance with the daily program was categorized and standardized, in order to determine the construction of an interactive spreadsheet. The digital format included data recording, calculation of OEE indicators per machine and per product, frequency of events reported as downtime per day and per month, and also calculation of economic losses due to monthly inefficiency per product type. Subsequently, the results of the OEE calculations were checked and validated. Moreover, the results were graphed in order to visualize the behavior of the line. The results showed that the line presents a low OEE level of 65%, due to downtime per machine and per product, causing considerable economic losses. The causes of the inefficiency were mainly the lack of raw material and the problems with the gumming of the product. The factors that affected the OEE were non-conforming product rolls. Finally, it is concluded that the digital format designed for the OEE calculation is a successful tool for efficient decision-making in the organization, so it is recommended to implement it in other production lines and plants.
