摘要
为解决顾客/专家常在多个评价值间犹豫不决的问题,结合犹豫模糊术语集和质量功能展开将顾客需求及重要度转化为产品延伸服务工程特性及重要度。基于min-upper和max-lower算子解决犹豫模糊术语集的多样化粒度问题,利用二元语义词计算方法将犹豫模糊术语集转化为区间数形式,采用区间数偏好度计算方法计算顾客需求的重要度和产品延伸服务工程特性的重要度。通过对定性候选服务规格的量化,建立以顾客满意度最大化、服务实现成本和服务响应时间最小化的多目标多约束优化模型,利用灰色速率关联度将其转化为单目标规划模型进行求解。最后,以某数控机床服务工程特性方案规划为例,验证了所提方法的有效性。
To manage the problem that customers/experts hesitated between several values,Hesitant Fuzzy Linguistic Term Set(HFLTS)and QFD were employed to translate the Customer Requirements(CRs)and their importance degrees into PES functional requirements and their importance degrees.Two aggregation operators,min-upper and max-lower were used to deal with the problem brought by the inconsistent granularity among different hesitant fuzzy linguistic terms.The method of two-tuple linguistic was applied to transfer HFLTS into interval-valued number.The preference degree of interval utilities was provided to compute the importance degrees of CRs and those of PES functional requirements.By quantifying the qualitative candidate attributes,a multi-objective and multi-constrained optimization model to maximize customer satisfaction and minimize service cost and service response time was established,which transformed into a single objective model by grey rate for solving.An example of service functional requirements optimization for controlled machine tools was given out to demonstrate the effectiveness of the proposed approach.
