3. Excerpts from Abstract
“This study was divided into two phases with an overall goal of developing a process-driven layout for the laboratory with a streamlined process flow and an effective utilization of resources. In Phase 1, Lean and Six Sigma techniques were used to develop a floor plan which facilitated analyzers to be grouped into “cells” that would improve the workflow. In Phase 2, alternative layouts with different “cell” configurations and staffing levels were evaluated using simulation. This study demonstrates the effectiveness of Discrete Event Simulation (DES) to validate the proposed, process-driven layout.”
