分析了全终端网络可靠性设计问题,针对单目标优化存在的不足,建立了一种更加贴近工程实际的极大化可靠度,同时极小化投资成本的多目标优化模型,并利用模拟退火算法对其进行了优化求解。计算机仿真实例表明:模拟退火算法在求解此问题时,无论是在Pareto解的数量上还是在Pareto解的范围上都能得到较好的优化效果。
The design problem of all - terminal networks reliability is analyzed. For the shortfall of single- objective optimization, a multi - objective optimization model which minimize the cost and maximate reliabilities is founded. The optimization model is solved by SA. Computer simulation shows that SA can get a satisfactory optimization result on range and quantity of Pareto optimal solutions.
