New approaches to evaluating the overall efficiency of equipment

The competitiveness of Russian industrial companies in modern realities can be ensured by the introduction of a lean production system, which is based on achieving high product quality at low production costs. One of the tools for evaluating the effectiveness of the use of lean manufacturing tools is the calculation of the overall equipment efficiency index (OEE). Thanks to the use of this indicator, the company timely identifies and eliminates losses, conducts a comparative analysis of the progress and improvement of equipment performance. The article discusses the methodology for calculating OEE, as well as the advantages and positive effects of using this indicator when implementing a lean manufacturing system. Losses associated with the use of human capital are allocated to a separate group when determining production losses, since frequent changes of employees will not be able to ensure proper productivity, especially of high-tech equipment. In this regard, along with the consideration of key indicators of the availability of production mechanisms, the productivity of work processes and the indicator of the quality of products, the calculation of the OEE indicator is supplemented by the coefficient of constancy of production personnel (CE). The author also proposed a system of factors of different order that determine the reasons for the deviation of actual production results from the planned ones according to four main indicators: availability, productivity, product quality, constancy of production personnel - with the help of this system, employees can better interpret the obtained indicators, understand changes and trends affecting production.
