A quality improvement method for building materials and equipment based on quality gene

Good quality and low manufacturing cost are the two main factors for the enterprises to increase their core competitiveness. in order to reduce manufacturing cost and to promote quality of product, we propose a quality improvement (qi) method based on product quality gene evolution for building materials and equipment. first, we present the connotation of the product quality improvement based on quality gene. second, the product quality gene evolution method based on genetic algorithm is adopted to achieve the product quality improvement. finally, we use mill-type cylinder tube as an example to illustrate the proposed algorithm process. experimental results have shown that the proposed approach is able to support quality improvement.
