服装里料性能的综合评价

Comprehensive evaluation on garment lining properties

针对服装里料性能指标较多的问题,采用综合评价方法对其进行排序。首先,将各指标的类型一致化,将极小型指标和区间型指标均转化为极大型;然后消除各指标间量纲和量级间的差异;再确定各指标的权重系数;最后,将多项性能指标合成一个综合评价指标。对比分析结果表明:采用综合评价方法,即先用极大化线性比例法消除指标间量纲和量级的差异,经极差确定权重,再用多项指标线性加权,得出的评价指标数值差异较大,可更好地区分服装里料性能之间的差异;10种服装里料中羽纱布排名第1,性价比高;有光弹力色丁布因3项性能指标较差,性价比最低。

Aiming at the problem on too many indicators to describe garment linings＇ performance,the comprehensive evaluation method should be employed to rank them. Firstly,the type of indicators should be consistent,i. e. the indexes of minimal type or interval type should be converted into the maximal type. Secondly, the difference of dimension and magnitude between different indexes should be eliminated. Thirdly,the weight factor should be determined. Finally,a comprehensive evaluating index was integrated. Comparison indicates the comprehensive evaluation method is adopted, i. e. the maximizing linear proportion method is firstly adopted to eliminate the difference between dimension and magnitude,the weight is determined by the rank factor and the linear weight is performed so as to obtain the larger difference,and it could distinguish the garment linings better. In the 10 kinds of garment linings,the camlet ranks number one,which has a higher performance to price ratio,and the bright elastic satin ranks the lowest because three properties are the worst.
