相对评价法是指在某一团体中确定一个基准，将团体中的个体与基准进行比较，从而评出其在团体中的相对位置的评价。采用标准分数进行评价，实际是表示考察的对象在总体中处于什么位置，所以这种评价是一种相对评价。
在此基础上构造了该法的相对值评价模型，减少了计算量，从而可以方便地把实物期权机制融入到评价中去。
Then an appraisal model for relative value is set up to reduce the computation involved, thus enabling the real options thinking to be combined into the appraisal easily.
然后利用数据包络分析法(DEA)建立了土地利用相对效率评价模型，给出了判断准则与变量设定。
A model to evaluate the comparative efficiency of land is also set up by means of DEA.
采用随机键，将连续的粒子位置向量转化为离散的解向量，并通过提出相对最短距离法来评价解集的优劣。
The random key was adopted to change from continuous particle position vectors to discrete solution vectors. And the method of relatively minimum distance was proposed to evaluate the Pareto muster.
