基于模糊数据处理的我国机床技术差距评价体系

Evaluation system of machine tool technology gap in China based on fuzzy data processing

长期以来,我国以数控机床为代表的装备制造业重点产品技术差距缺乏量化测度研究,导致无法用客观的表征方法来衡量和评价数控机床技术发展水平。针对以上问题,从共性技术、典型主机产品、数控系统和关键功能部件4个方向出发进行技术要素项细分,构建了对标世界先进领先水平的高档数控机床技术差距评价体系;提出我国机床技术水平与国际(地区)先进水平的年代差距量化表征方法;建立了基于模糊数据处理的分项技术水平评价模型、共性技术产品水平评价模型和产品关键技术综合评价模型。最后,基于该体系进行了大样本数据调研,基于评价模型进行了机床技术年代差距量化分析,评价结果可为政府科学决策及行业发展规划提供重要支撑。

For a long time,the technology gap of key products in equipment manufacturing industry represented by CNC machine tools is lack of quantitative measurement research,which makes it impossible to use objective characterization methods to measure and evaluate the technical development level of NC machine tools.In view of the above problems,an evaluation system for the technical gap of high-end CNC machine tools is constructed,starting from the four directions of common technology,typical host products,CNC system and key functional components,which are subdivided into the technical element items.A quantitative characterization method of the age gap between China's machine tool technology level and the International(regional)advanced level,is proposed.Evaluation models for the sub item technology level,common technology/product level evaluation model and product key technology are established based on fuzzy data processing.Finally,a large sample data survey is carried out based on the system,and a quantitative analysis of the age gap of machine tool technology is carried out based on the proposed evaluation models.Evaluation results can provide the important support for the government′s scientific decision-making and industry development planning.
