ABSTRACT—This paper uses the methodology established in the ET ’08 Management Track
paper: “Continuous Extrusion Optimization SystemTM: Measure Twice, Cut Once. Repeat,” to
analyze an extrusion operation through mathematical modeling. The process reveals the proper
equipment enhancement and replacement decision process to maximize profitability. The
analysis is based on actual work performed for anonymous AEC members, and the equipment
and profile data and information have been masked and/or modified slightly to protect their
