Tracking the product quality model of manufacturing system

High competition, demand for high quality and budget cut has put aerospace manufacturers under tremendous pressure. In order to survive and remain competitive, manufacturing industries are forced to analyze and learn more about their manufacturing system's behavior under diverse operational conditions. This work is the part of on going research for developing a model for continuous tracking of product and process quality during manufacturing. The aim of this paper is to present the need and general approach for tracking the product quality of manufacturing products with a view to understand the action and interaction of variables associated with various process in the system at any point in time. Such a work will provide accurate predictions of the systems behavior and allow to take corrective action as the problem occur rather than cumulating the problem. It is hoped that the work would have general applicability to any manufacturing process.
