Machine Oee Monitoring And Analysis For A Complex Manufacturing Environment

OEE (overall equipment effectiveness) is a well-established KPI metrics to measure the equipment effectiveness. OEE has been widely used for many industry as a quantitative tool for measuring productivity. The biggest challenge in the OEE implementation is due to the complexity of the plant with many variety of machines. In this paper, we present a unified OEE data collection method that is able to connect both brown field legacy machines and green field machines. An integrated OEE monitoring system architecture is proposed for large scale of implementation. A case study demonstrates the successful implementation of the OEE system for the productivity improvement.
