Because the coefficient of influence power and the output multiplier of education industry are low , the efficiency is not high to spur economic growth 教育行业的产出乘数和影响力系数比较低,依靠增加教育消费直接拉动经济增长的效率不高,从长期看并不划算。
Fifthly , the paper utilize the fuzzy mathematics principle to analyse model setting up , model discerning , fuzzy decision - making process of fuzzy mathematics , the conclusion is drawn that we appraised mould cost with fuzzy similar comparative method , with fuzzy mathematics the expert ' s behavior is simulated as well as the useful information is drawn lastly , the fuzzy similar appraisal mathematics model on basic of man - hour method is set up , the characteristic factors to describe automobile covering of mould and coefficient of influence factor to synthetically judge similar work are confirmed which raises the precision of price by mathematics foundation , work characteristic sureness , influence factor sureness , management of sample data , etc . of weight of factor of model , the paper set up more intact theoretical system of mould price estimate with fuzzy similar comparative method 建立了基于工时法的模糊相似评价数学模型,确定了描述汽车覆盖件模具的特征因素;并确定了综合评判工件相似性所用各影响因素的权重集合,提高了模具价格估计的精度。通过对数学模型的建立、工件特征因素的确定、影响因素权重的确定、样本数据的管理等的研究,本文较完整的建立了利用模糊相似比较方法估算模具价格的理论体系。在分析模具报价流程和决策过程的基础上,开发了汽车覆盖件模具计算机辅助报价系统,该系统安全、方便、准确。
