摘要常權(quán)綜合評(píng)價(jià)中由于評(píng)價(jià)指標(biāo)值間的交互作用往往使評(píng)價(jià)結(jié)果失準(zhǔn)，本文提出一個(gè)變權(quán)綜合評(píng)價(jià)模型及一個(gè)模型序列，使評(píng)價(jià)結(jié)果突出主要指標(biāo)的作用，減輕因次要指標(biāo)值過(guò)大給評(píng)價(jià)結(jié)果帶來(lái)的影響。 - First this paper analyses weighted deviation model ( wdm ) put forward by len swanson & martha l . stocking . it is found that when the constraints are made up of question numbers , question grades and other information with different dimensions , the calculated values of dl , du cannot be compared . then the wdm model is further improved and the constraints of the model are simplified in the way that only the question grades are strictly constrained while other constraints are reflected by the distribution of grades
首先，本文對(duì)lenswanson & marthal . stocking提出的離差加權(quán)模型( weighteddeviationsmodel ，簡(jiǎn)稱(chēng)wdm模型)進(jìn)行分析，發(fā)現(xiàn)當(dāng)約束條件既有題數(shù)，又有題分和信息量時(shí)，由于各約束條件的單位(量綱)不同，根據(jù)約束條件計(jì)算出的d _ l _ j ， d _ u _ j的值不可比。
