Application desirability function for automotive paint thickness

© American Society for Engineering Management, 2015.In automotive painting processes one of the quality characteristics observed is the thickness of the paint, and it is so important that for one vehicle there are at least 31 points to review. Therefore, the problem arises when decisions should be made in order to define if the vehicle's paint has achieved the quality expected or not. When a quality indicator is based on multiple responses, it becomes devious to analysis and techniques are required to manage this complexity. The desirability function is a technique used to convert multiple response indicators into one metric. It allows each indicator to have their own scale and goal, transforming them into a global one (D) using a standard scale (0 to 1). The implementation and effectiveness of this approach are going to be discussed in this paper with a numerical and practical example.
