Dimensional Variation Analysis (DVA) is a statistical approach used in manufacturing and engineering to predict and control the variation in dimensions of parts and assemblies, ensuring product quality and performance. It involves modeling the geometric variations and tolerances to optimize design and manufacturing processes, reducing defects and improving efficiency.
