摘要
针对金刚石钻头综合评价中各指标的不相容性和模糊性,提出基于模糊物元分析的金刚石钻头综合评价方法。该方法将待评价金刚石钻头、评价指标及其特征值作为物元,根据专家经验和工程实际建立关联函数,通过计算综合关联度得到最优的金刚石钻头。用实例与模糊优化理论模型等进行了对比,得到了一致的结果。
Aimed at the incompatibility and fuzziness of indices in diamond bits comprehensive evaluation, a comprehensive evaluation method is presented based on fuzzy matter element analysis. The evaluation on diamond bits, evaluating indices and its characteristic value are taken as matter elements, relational function are constructed according to the expert experi- ence and practical engineering, and optimum diamond bit is obtained by calculating the comprehensive relational degree. Results achieved are consitentcoincident by comparison on cases and fuzzy optimization theory model.
