2、h as Japan and South Korea, the gap is narrowing, and this gap is mainly reflected in the accuracy management. The level of accuracy management directly affects the quality of the construction of the ship, as well as the

3、 economic benefits of the shipyard. As a result, if Chinese shipbuilding industry want to become the first shipbuilding power in the world and keep up with the pace of development of the times, it is necessary to impleme

4、nt the accuracy management in the shipbuilding to ensure the quality of the construction of the ship and promote productivity. Based on the analysis of the concept and composition of management system, this thesis establ

5、ished the accuracy management based on the hull process lane construction; elaborated the contents of accuracy plan in detail; combined with the features of hull process lane construction, elaborated the accuracy control

6、 processes in every stage of hull process lane construction ; established a database. The main contents and results of this thesis include: 1. According to the characters of hull process lane construction, this article f

7、irst explained concept and composition of management system, and then builded an accuracy management system based on this theory. 2. Elaborated the contents, roles and demands of accuracy plan in detail first, this arti

8、cle introduced the theory of dimension chain, list the distribution of compensation, set up the theoretical formulas about compensatory value. Next this article analyzed the process of placing compensation and the princi

9、ple of compensation for dimensional accuracy. At last, this article summarized accuracy standards for hull construction, evaluated the management of hull accuracy construction. All these are base of the accuracy manageme
