用动态规划方法优化设计船舶车辆甲板结构

基于规范的车辆甲板结构优化设计在数学上是一个较大的非线性规划问题，而且为了满足实际需要，其中一些变量只能离散变化。本文将该问题处理为三阶段决策问题，因而能运用动态规划方法有效地求解。通过一个实例详细说明求解过程，从中看出应用动态规划方法解决基于规范的船舶结构优化设计问题的特色。

OPTIMAL DESIGN OF VEHICLE DECK STRUCTURES BY DYNAMIC PROGRAMMING TECHNIQUE

Rule-based optimal design of vehicle deck structures is mathematically quite a large nonlinear programming within which some variables can only be discrete for the sake of engineering practice. In this paper the problem is formulated as a tristage decision process and can easily solved by using dynamic programming instead of nonlinear programming which may involve much difficulty. An example is presented to demonstrate the solving process, from which the characteristics of application of dynamic programming to rulebased ship structural design can be seen.
