基于RMS关键特征偏好排序的重构方案评估方法

针对如何构建反映可重构制造系统本质特性的评估指标定量模型，以及某一重构方案相对其他方案优势和劣势都绝对明显情况下如何实现多方案优选的问题，提出一种基于RMS关键特征偏好排序的重构方案评估方法.在综合考虑可重构机床组件调整、制造单元调整基础上，建立衡量RMS可缩放性、可转换性、可诊断性、模块化、可集成性和定制化等特征的量化模型，以此为基础形成重构方案的评估指标，并采用层次分析法分配评估指标权重.评估过程中，先从局部采用部分偏好排序评估方法分别对方案的优势和劣势进行评估，然后从整体上通过完全偏好排序评估方法对重构方案的净优势进行评估，最终得出重构方案的综合评估结果.并以某研究所RMS车间为例，阐述了该方法的实施过程并验证其有效性和实用性. 

Reconfiguration Plan Evaluation Based on Preference Ranking of Key Characteristics in Reconfigurable Manufacturing System

In order to develop a quantitative evaluation index model for the essential characters of RMS (reconfigurable manufacturing system) and to optimally select the configuration plans with their outstanding advantage and disadvantage comparison,an evaluation method was proposed based on PROMETHEE (preference ranking organization method for enrichment evaluation).Analyzing the reconfiguration of the reconfigurable machine tool and manufacturing cell,a basic evaluation index and the quantitative model was designed to take the key characters of RMS,scalability,convertibility,diagnosability,modularity,integrability and customization.AHP (analytic hierarchy process) was used to assign the weight for these indexes.In the evaluation process,PROMETHEE I was applied firstly to analyze the advantage and disadvantage for each alternative plan.Secondly,PROMETHEE Ⅱ was adopted to analyze the comprehensive advantage.Finally,the sequence of alternative plans was decided based on the analyzed results.A case study from a shop floor of an institute was presented to validate the effectiveness and practicability.
