SPEAKER: Prof. Dan McCarville, ASU
TOPIC: “Constrained Wine Blending Optimization – Must Use All of the Grapes”
ABSTRACT: Producing fine wines has similar manufacturing problems and opportunities as other product manufacturing industries. It is common to hear winemakers describe their wines with qualities such as nose, color, taste, fruitiness, finish, acidity, earthiness, and others. Quantifying these measures for experimental purposes can provide some challenges. Small producers of high quality wines, often referred to as boutique wineries, have a very limited supply of grapes, and must use virtually all of their barrels of wine they produce. This presents an interesting constraint for these small producers when determining their wine blends prior to bottling. Clearly a mixture experiment can be performed with the components being barrels from different vineyards, or yeasts, or other processing treatments. A second constraint requires all of the barrels of wine produced be used in one or more blends. Additional constraints such as vineyard designations, appellation designations, and varietal designations can also affect both the experimental design and the use of the resulting model. This presentation will provide an explanation of these constraints while performing a wine blending mixture experiment for a boutique winery, and applying the resulting models to identify the optimal, sub-optimal, and residual solutions.
BIO: Dan McCarville received his M.S. and Ph.D. from Arizona State University in 1994 and 1999, respectively. His research interests are in quality engineering, industrial statistics and engineering management with a general focus on continuous improvement methodologies. Prior to joining the Arizona State University faculty, Dan had worked 27 years in the semiconductor industry for Motorola and Mindspeed Technologies where he led teams through the development and implementation of large scale quality systems and complex manufacturing processes.
