Abstract

Multi-criteria decision-making (MCDM) is well known as one of the most important solutions that seeks to identify the best alternative among several options. It has a significant effect on the effectiveness of many technical disciplines within the industrial field, especially electrical discharge machining. This paper presents the findings of a multi-criteria decision-making study involving the powder-mixed electrical discharge milling (PMEDM) of cylindrically shaped tool steel 90CrSi components. As performance measures for the PMEDM process, the material removal rate (MRS) and surface roughness (SR) are selected. Three different techniques (CRITIC, MEREC, and IDOCRIW) are applied in sequence to determine the weight value of the quality indicators. The key MCDM methods used for ranking the alternatives are the Combined Compromise Solution (COCOSO) method and the Stable Preference Ordering Towards Ideal Solution (SPOTIS). The experimental study indicates the ranking tables under different scenarios and proposes the best alternative for the PMEDM procedure.

基于COCOSO、SPOTIS算法和加权方法的粉末混合放电加工过程多准则决策

多准则决策（MCDM）是众所周知的最重要的解决方案之一，旨在确定几个选项中的最佳替代方案。它对工业领域中许多技术学科的有效性有着重大影响，尤其是放电加工。本文介绍了一项涉及圆柱形工具钢90CrSi部件的粉末混合放电铣削（PMEDM）的多准则决策研究的结果。选择材料去除率（MRS）和表面粗糙度（SR）作为PMEDM工艺的性能指标。依次应用三种不同的技术（CRITIC、MEREC和IDOCRIW）来确定质量指标的权重值。用于对备选方案进行排序的关键MCDM方法是组合折衷解决方案（COCOSO）方法和理想解决方案的稳定偏好排序（SPODIS）。实验研究表明了不同场景下的排名表，并提出了PMEDM程序的最佳替代方案。
