【Abstract】 In view of the efficiency problem of hull curved section manufacturing, a Constant Work-In-Process(CONWIP) control strategy for virtual assembly line of hull curved section is proposed. According to the production flow of virtual assembly line of hull curved section, the operation volume of each routing in each section is determined. The CONWIP control strategy is expounded in such as CONWIP control principle, routing loop setting, and simulation model parameter setting. The applicability of CONWIP control strategy in virtual assembly line of hull curved section is determined with the test results comparison and the proportion comparison of supply delay time at work station. The research results show that the strategy can effectively solve the problems of low manufacturing efficiency and supply delay time at work station of hull curved section.更多还原
