最近的研究表明,模拟退火与正交阵列为基础的邻域功能,可以帮助在寻找一个解决方案的参数化问题,这是更接近一个最佳的相比,传统的模拟退火。以前的模拟退火研究仅分析了参数化问题变量的主要影响。实际上,在许多参数化问题中,变量间的相互作用是存在的,既要考虑变量的主效应,也要考虑变量间的相互作用。本文提出了一种改进的基于正交表的邻域函数(IONF)的模拟退火算法,该算法考虑了变量间的交互作用。在求解了一组变量间存在交互作用的参数化基准函数问题后,基准测试的结果表明,基于IONF的模拟退火算法的性能明显优于基于现有正交表邻域函数和标准邻域函数的模拟退火算法.最后,将改进的正交表模拟退火算法应用于乳化炸药包装机的优化设计,评价了该算法在真实的问题中的适用性,进一步验证了算法的有效性。
Recent research shows that simulated annealing with orthogonal array based neighbourhood functions can help in the search for a solution to a parametrical problem which is closer to an optimum when compared with conventional simulated annealing. Previous studies of simulated annealing analyzed only the main effects of variables of parametrical problems. In fact, both main effects of variables and interactions between variables should be considered, since interactions between variables exist in many parametrical problems. In this paper, an improved orthogonal array based neighbourhood function (IONF) for simulated annealing with the consideration of interaction effects between variables is described. After solving a set of parametrical benchmark function problems where interaction effects between variables exist, results of the benchmark tests show that the proposed simulated annealing algorithm with the IONF outperforms significantly both the simulated annealing algorithms with the existing orthogonal array based neighbourhood functions and the standard neighbourhood functions. Finally, the improved orthogonal array based simulated annealing was applied on the optimization of emulsified dynamite packing-machine design by which the applicability of the algorithm in real world problems can be evaluated and its effectiveness can be further validated.
