Dow Chemical design for Six Sigma rail delivery project

Dow Chemical needed to find a solution that would enable them to meet the forecasted increase in demand for a line of products. In order to find the most cost effective solution that met all project criteria, Dow Chemical implemented Six Sigma principles. By utilizing the Six Sigma methodology combined with discrete event simulation, Dow was able to devise a solution that would allow them to meet the increase in demand with savings of $2.45 MM in capital expenditure. This paper outlines the steps that Dow took to complete the project, as well as a discussion of the simulation models and project results.
