SOVA - Stream of Variation Analysis System for Multistage Manufacturing Processes
This piece is based on the work done by DCS Dimensional Control Systems in cooperation with Dr. Jianjun (Jan) Shi at the University of Michigan and Drs. Darek Ceglarek and Shiyu Zhou at the University of Wisconsin - Madison, with the support of a two million dollar grant from the Advanced Technology Program of the National Institute of Standards and Technology.
SOVA is a method of applying variation analysis as part of the design and manufacturing process to drive robust design in order to reduce costs in manufacturing.
Developed in the late 90's and early 2000's and documented in the book "Stream of Variation Modeling and Analysis for Multistage Manufacturing Processes" (Jianjun Shi, 2006, CRC Press, ISBN 1420003909), it forms a basis for many of the programs DCS provides for customers and is similar to many process established by leading manufacturers in the automotive and aerospace industries.
