摘　　要：构建了物理模型逼真度、数据建模方式、作业流程简化程度三个维度的逼真度层次划分框架,用模糊层次分析法(Fuzzy AHP)对模型逼真度进行定量度量。该方法既可在仿真实施前帮助建模者建立较规范的逼真度设计,又可在建模后对已有模型的逼真度进行定量度量,有效地保证了仿真活动的规范性和仿真代价与仿真效用的合理化。最后以某机械零部件配送中心仿真为例,对该配送中心规划的不同时期的仿真模型进行逼真度设计和度量,进而得到有关配送中心仿真逼真度设计与管理的一般性结论。In this paper, we provided a hierarchical framework of three dimensions （physical model fidelity, data-modeling method and operation-flow extent） and adopted Fuzzy AHP to be a suitable method to measure the model fidelity. The method could help the modeler make a structuralized fidelity design and measure the fidelity of the designed model. It ensured both the standardability of the simulation and the rationality of simulation＇s effectiveness and cost. Taking a mechanical parts distribution center as an example, we designed and measured the fidelity of the simulation models in different periods to draw general conclusions about the design and management of fidelity.
