Spill Smart mask improvement analysis

Abstract

SSW Holding Co. Inc. has introduced a revolutionary spill retention technology to the OEM refrigeration market for refrigerator shelving that does not require a phy;ical border around the perimeter of the glass shelf trademarked Spill Smart TM. The spill retention is accomplished by applying a hydrophobic border around the perimeter of the glass shelf via a spray system. A masking system is in place to keep the spray from migrating to the spill retention rectangular area. The current masking method used during the spray application of the spill retention border allows migration of the treatment towards the middle of the glass shelf, thus resulting in spill retention border lines that are not crisp straight lines. SSW Holding needs an improved masking system that will minimize migration to the spill retention area and provide crisp border lines. This paper will utilize the rational decision making approach to explore alternatives, and establish the attributes of a masking system that will produce crisp straight border lines with minimal migration to the spill retention area. The weighted multi attribute decision matrix approach will be used to choose the best alternative to develop, validate and ultimately introduce to manufacturing.
