基于PERT与CPM的船舶分段建造计划协调与优化

分析了现代精益造船模式下要求的船舶分段建造流程以及国内船厂生产计划的制定方式，利用计划评审技术（PERT），结合关键路径法（CPM），自动生成船舶分段产品建造计划，并在工期和成本方面对建造计划进行了协调与优化．基于MS-Project软件，用VBA编制了实用程序，并以大连某船厂建造的某油船为实例进行了计划编排与优化．与生产实际对比表明，该计划方法是可行的，为船舶建造初期制定生产计划提供了一种实用简便的方法．

Ship block construction plan coordination and optimization based on PERT and CPM

Ship block construction process under modern lean shipbuilding mode and the method of planning shipbuilding in our country are analyzed and summarized. Combining PERT with CPM, the ship block construction plan is created, and the building plan is coordinated and optimized in duration and cost. An applied program using VBA based on MS-Project software is developed to implement the method. As an instance, the block construction planning of a tanker in a Dalian shipyard is programmed and optimized. The calculated instance and results show that the approach is feasible and practical to make ship block construction plan in the early days of shipbuilding.
