quality loss function


quality loss function
= QLF
A measure of the effectiveness of quality control techniques, which reflects the economic losses incurred by the customer as a result of:
• maintenance and failure costs;
• damage to the environment;
• the costs of operating a product. QLF was developed by Genichi Taguchi; it differs from other quality approaches that accept random variation within limits. QLF recognizes that any deviation from the designed specification involves extra cost for the consumer.
