摘要
为通过在装备的各组成单元之间,对装备的研制经费实施最优分配,继而获得最大化的装备整体作战使用能力的现实需求,选择由锅炉、主汽轮机、主冷凝器、汽轮给水泵等4个基本单元组成的船舶蒸汽动力系统为对象,运用系统动力学(system dynamics,SD)方法,建立各项费用与动力系统总体性能之间的关系模型,并转化为SD仿真平台上的动力系统各设备经费结构优化模型。经过系统分析和对照仿真结果,找出费用在动力系统中各个设备之间分配的特殊规律,在功率既定情况下,确定动力系统费用的最小值以及在各个设备之间的最优分配结构,形成基于SD理论、面向系统性能最大化,在装备组成单元层面开展经费结构优化的方法。
For acquiring the realistic demand of maximizing the integral operational ability of equipment,the optimal allocation of equipment develop cost is carried out among the equipment constituent units,the steam power system of ship including boiler,main steam turbine,main condenser,turbine driven feed pump is selected as study object.The relation model between the costs and the overall performance of power system is established utilizing system dynamics method,which is translated into the optimization model of each equipment cost structure for the power system on the system dynamics simulation platform.The special rules of cost allocation among the equipment constituent units of power system are found out by system analysis and contrasting the simulation results.The minimum cost of the power system and the optimal allocation structure among each equipment are determined under the condition of power invariability.And the cost structure optimization method based on the theory of system dynamics is formed,which can face the maximization system performance on the equipment constituent units.
