基于逼近理想解排序法的进出口食品安全监管工作风险评估

当前,我国进出口食品安全监管工作面临着严峻的形势,该项工作的风险包括产品风险、队伍风险以及其他风险。利用逼近理想解排序法（technique for order preference by similarity to an ideal solution,TOPSIS）分析方法,结合风险分析原理和危险评估指数,建立进出口食品安全监管工作风险量化评估的方法,可科学判定工作风险大小。对连云港口岸进出口紫菜监管工作进行了评估,纵向比较了连云港地区近3 年来进出口紫菜监管工作风险的量化值,通过举例表明该模型在进出口食品安全监管方面具有良好的应用效果和前景。     

基于熵权-逼近理想解排序法结合体外模拟消化评价功能性水稻品质

目的 探究不同品种功能性水稻的品质差异性指标,并进行综合品质评价。方法 以来源于咸宁市农业科学院的7种功能性水稻为研究对象,对其7项基本营养成分、9种矿物质元素含量、3类淀粉含量和1种血糖预测指数共计20项营养品质指标进行对比分析,在利用正交偏最小二乘法-判别分析(orthogonal partial least-squaresdiscriminationanalysis,OPLS-DA)筛选重要差异性指标的基础上,建立熵权-逼近理想解排序法(technique for order preference by similarity to ideal solution, TOPSIS)模型对7种功能性水稻的综合品质进行评价。结果 不同品种功能性水稻的基本营养成分在较小范围内波动,但钾元素含量和淀粉含量的变化范围较大,其中水稻GN 7、GN 5、GN 6在钾元素含量方面表现较好,水稻GN 4、GN 1、GN 3抗性淀粉含量最高,预估血糖生成指数(estimated glycemic index, eGI)值更低,抗消化能力优于其他品种。OPLS-DA分析筛选出锌、钠、钾、抗性淀粉、钙、镁、...     

基于熵权法和改进TOPSIS法的烤烟质量综合评价

为了更好地进行烤烟质量综合评价,综合使用熵权法和改进的逼近理想解排序法（Technique for Order Preference by Similarity to Ideal Solution,TOPSIS）对114个烤烟样品的外观质量、感官质量、常规化学成分协调性进行综合评价,得到外观质量接近度、感官质量接近度、化学成分接近度和综合质量接近度,并采用简单相关分析法分析烤烟综合质量指标与各质量接近度间的相关性。结果表明：(1)熵权法得到的外观质量、感官质量和常规化学成分在综合评价中的权重分别为0.316、0.380和0.304;(2)四川凉山州会理县太平镇、云南红河州弥勒市弥阳镇、云南红河州建水县临安镇、四川凉山州会理县黎溪镇和四川凉山州德昌县茨达镇生产的清甜香型烟叶质量较好;(3)与清甜香型烟叶综合质量呈正相关关系的指标包括：外观指标中的色度、身份、油分、颜色和叶片结构,感官指标中的干燥感、圆润感、香气量、杂气、透发性、余味、香气质、程度、刺激性、细腻程度和工业可用性,化学成分中的总植物碱和糖碱比。     

Physicochemical,bioactive, and sensory properties of persimmon-based ice cream: Technique for order preference by similarity to ideal solution to determine optimum concentration

In the present study, persimmon puree was incorporated into the ice cream mix at different concentrations (8, 16, 24, 32, and 40%) and some physicochemical (dry matter, ash, protein, pH, sugar, fat, mineral, color, and viscosity), textural (hardness, stickiness, and work of penetration), bioactive (antiradical activity and total phenolic content), and sensory properties of samples were investigated. The technique for order preference by similarity to ideal solution approach was used for the determination of optimum persimmon puree concentration based on the sensory and bioactive characteristics of final products. Increase in persimmon puree resulted in a decrease in the dry matter, ash, fat, protein contents, and viscosity of ice cream mix. Glucose, fructose, sucrose, and lactose were determined to be major sugars in the ice cream samples including persimmon and increase in persimmon puree concentration increased the fructose and glucose content. Better melting properties and textural characteristics were observed for the samples with the addition of persimmon. Magnesium, K, and Ca were determined to be major minerals in the samples and only K concentration increased with the increase in persimmon content. Bioactive properties of ice cream samples improved and, in general, acetone-water extracts showed higher bioactivity compared with ones obtained using methanol-water extracts. The technique for order preference by similarity to ideal solution approach showed that the most preferred sample was the ice cream containing 24% persimmon puree.     

基于Vague交叉熵的Topsis产品方案优选方法

产品的设计方案优选是个复杂的多准则团队协同决策过程。为解决产品设计方案优选中多准则间的关联被忽视的问题,提出一种改进的Topsis方法模型,即通过Vague交叉熵建立起多准则下的单个专家评价结果模型,再应用证据推理理论融合各专家的冲突性的评价结果,得到各方案综合评价值,以判断出优解顺序。最后,以共享底盘开发的方案评价与选择作为实例验证了该方法的可行性与有效性。
