Construction and Application of Improved Quality Control Model for Marine Shaft System Design

In order to solve the problem that the relation matrix is too subjective and the sample demand is too large in the existing quality control model for marine shaft system design, the relation matrixes are established by grey relational analysis method to calculate the weights of technical characteristic indexes and construction technology indexes, and on this basis, the improved quality control model for marine shaft system is constructed. Taking a shaft system design process as an example, the improved quality control model is built to provide scientific quality control basis for it, thus the effectiveness of the improved model is verified.
