A novel calculation method was proposed for evaluating the quality loss level of outsourcing components in complex product supply chain, which were ordered in small batches crossing multi-stages. Specially, Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) was used for appraising static quality loss in an independent stage, which concerned the optimal quality objective and tolerances according to purchaser’s quality requirements. Grey Relational Analysis was employed for reflecting the dynamic quality loss covering several order procedures by comparing theoretical learning effect and realistic quality improvements. The comprehensive quality loss indicator was designed combining static and dynamic quality losses, which can describe the quality assurance in a stage and quality improvement effect in trend. The numerical study was conducted for showing the above calculation process and the effectiveness of the new method.
