A Framework Based on OEE and Wireless Technology for Improving Overall Manufacturing Operations

Abstract

Manufacturers have the challenge to increase productivity given complex manufacturing environments. A source that provides substantial levels of productivity is the overall equipment effectiveness (OEE) metric, which is an indicator to improve not only equipment utilization; but also the overall manufacturing operations, because of the valuable information that comes from the availability, performance and quality rates. Although information technologies have been introduced, companies use manually recorder data and have complicated measurement procedures. As a consequence, inaccurate information is generated and opportunities to improve productivity are missed. This paper presents a continuous improvement framework based on Lean manufacturing philosophy, operated by a system of wireless devices to support the real time equipment performance metrics. In order to validate the framework, results of a case study are exposed.

Energy Efficiency and Productivity Optimization of Industrial Cleaning Equipment

“…Considering section 2.2 and the herein described energy and energy consumption, the equipment productivity is subject to limitations, such as technical failures that can occur in correlation with organizational disturbances as failures in production order, schedule, material shortages or possibly connected with the equipment in itself, resulting in non-value-adding downtimes [6]. The attempted reductions of technically and organizationally induced productivity and resulting efficiency losses are predominantly influencing optimization measures for cleaning equipment [7].…”

“…The overall equipment effectiveness (OEE) is a widely recognized measurement instrument which assesses the operational behavior and productivity of a manufacturing system [6], [13]. The indicator can reveal efficiency losses and is obtainable from machines, plants, production areas or whole companies.…”
