    摘要:

    考虑当前制造业智能化发展趋势以及数控机床在现代制造工程领域所发挥的关键作用,提出了一种集质量功能展开(QFD)、模糊线性回归和0-1目标规划优点于一体的数控机床多目标优选法。在研究智能制造对数控机床特定要求的基础上,运用QFD考察智能制造需求与数控机床性能之间的因果关系,采用质量屋将智能制造的需求有机地融入数控机床选型中。基于模糊线性回归法确定智能制造需求与数控机床性能在质量屋中的相互关联程度,运用层次分析法计算智能制造需求指标的权重系数,并采用0-1目标规划法在众多候选数控机床中做出最佳选择。以某智能制造平台搭建过程中的数控机床多目标决策问题作为应用案例,从5台候选数控机床中挑选出综合性能最好的1台。研究表明,所提出的面向智能制造的数控机床多目标优选法具有较高的工程实用性。

    Abstract:

    Considering the intelligent development trend of manufacturing industry in current and the key role of CNC machine tool in modern manufacturing engineering, a multi-objective optimum seeking method of CNC machine tool is proposed, which combines the advantages of quality function deployment (QFD), fuzzy linear regression, and zero-one goal programming (ZOGP). On the basis of studying intelligent manufacturing’s specific requirements, QFD is utilized for examining the causal relationships between intelligent manufacturing’s requirements and CNC machine tool’s performances. The intelligent manufacturing’s requirements are incorporated into machine tool selection by house of quality (HOQ). Fuzzy linear regression is used to determine the extent of functional relationships between intelligent manufacturing’s requirements and machine tool’s performances in the HOQ. The weight coefficients of CNC intelligent manufacturing’s requirements indexes are calculated by analytic hierarchy process (AHP). Zero-one goal programming is used to select the optimal CNC machine tool. Taking the CNC machine tool’s multi-objective decision problem in constructing an intelligent manufacturing platform as application case, and the optimal one with high comprehensive performance is selected from five alternative CNC machine tools. The study result shows that the proposed multi-objective optimum seeking method of intelligent manufacturing oriented CNC machine tool has high practicability.
