摘要: |
计算机仿真是复杂系统优化的一种有效手段,但需要耗费大量机时,必须严格限制仿真次数。针对此提出了优化拉丁方试验设计方法,该方法需要较少的仿真次数,且兼顾方案的正交性和均匀性,采用Cholesky分解生成初始解,通过模拟退火算法对拉丁方矩阵进行优化,定义动态权重因子实现正交性与均匀性的权衡。最后构建了一个实例,通过试验结果证明采用优化拉丁方试验设计方法可以生成具有较好性质的仿真方案,且仿真次数少。 |

Abstract: |
Computer simulation is effective for the optimization of complex system. However, it is time-consuming. Therefore, the number of simulations must be strictly confined. To generate a good simulation plan, an optimized Latin hypercube sampling method is put forward. The method can not only reduce the number of simulations, but also ensure the generated plan of good orthogonality and proportional spacing. Cholesky decomposition was borrowed to generate initial solution, and simulated annealing algorithm was used to get optimized array. Also a dynamic weight parameter was defined to balance different optimization objectives. Finally, an example was constructed. The result shows that the optimized Latin hypercube sampling method can generate a sound simulation plan with less simulation. |
Keywords: computer simulation optimized latin hypercube sampling orthogonality uniform spacing |
