摘要： 由曲面数字化点进行曲面重构后的误差评价是反求工程需要解决的关键技术问题。随着计算机网络飞速发展以及反求工程的应用领域不断扩大，曲面拟合误差作为反求评价的单一目标已不能满足反求工程中产品设计制造的需要。在分析反求评价需求的基础上，提出了宽公差复杂曲面反求的多目标评价概念，建立了多目标评价模型，给出了模糊层次分析法的多目标评价方法，提出了网络化的反求工程多目标评价方式。

Abstract: Error evaluation of the reconstruction surface is one of the key technologies in reverse engineering (RE). With the rapid development of computer network and the widely application of RE, the error of surface fitting---the single aim evaluation of surface reconstruction can not meet the demand of the product design in RE. Based on need of evaluation in RE, the conception of complex surface with biggish tolerance (CSBT) of RE is proposed, a multi-object evaluation mechanism of CSBT reconstruction is established, a multi-object evaluation mode is given and a method of the network-based RE is presented.

Key words: Biggish tolerance, Complex surface, Multi-object, Reverse engineering
