Abstract: To improve product quality, the product quality is analyzed in depth in a broad sense involving its connotation and denotation. An idea of generalized product quality is thus presented with a relevant evaluation index system suggested including all functions and comprehensively clustered performance of a product in view of its construction, operation and process technology. In this way the complexity and relational hierarchy of the generalized product quality in evaluation are fully considered by introducing AHP in combination with grey theory to make the fuzziness, complexity and difficulty in quantification compatible with each other. Then, taking a domestic excavator as example, its generalized product quality is evaluated comprehensively, and the results show that the generalized evaluation system for product quality can provide a scientific basis for decision making on product design/manufacture, quality evaluation and orientation of enterprise.
