多目标最优化的实例研究

Multi-objective Optimization: A Case Study

Nazmul Hasan

摘要:

本文献的目的是通过一个端面铣削加工的案例研究来说明多目标最优化程序的应用。为此,面铣操作被设计为多目标最优化问题,然后使用优化例程求解以获得加工参数-切削速度(Vc)、进给速率(fz)和切削深度(t)的最佳值。面铣操作的公式化问题包括两个相互冲突的目标-最大化材料去除率(MRR)和最小化表面粗糙度(Ra)。在各种多目标最优化方法中,本文采用了五种方法,即全局准则法、字典法、加权和法、迭代约束法和遗传算法。然后比较这些多目标最优化例程的结果以反映它们的相对吸引力。

英文摘要:

The aim of this literature is to illustrate the application of multi-objective optimization routines through a case study of face milling operation. For this purpose, the face milling operation is designed as a multi-objective optimization problem and then solved to obtain optimum values for the machining parameters - cutting speed (Vc), feed rate (fz) and depth of cut (t) using the optimization routines. The formulated problem of face milling operation includes two conflicting objectives - to maximize Material Removal Rate (MRR) and to minimize surface roughness (Ra). Among various multi-objective optimization routines, five of them namely Global Criterion Method, Lexicographic Method, Weighted Sum Method, Epsilon Constraint Method and Genetic Algorithm are used in this literature. The outcomes of these multi-objective optimization routines are then compared to reflect their relative attractiveness.
