系统评价中的可加性评价函数及其判别

首先提出了系统评价模式的基本分类：总和评价模式、因果评价模式和果因评价模式，在此基础上指出，评价函数形式选择的首要问题不是线性和非线性的选择，而是加型函数和非加型函数的选择。然后，用无相互作用概念给出了可加性评价函数的一个判别定理，即：当各评价指标对总指标是无相互作用时，其评价函数是加型函数。

Additive Evaluation Function in Systems Evaluation and Its Discrimination

At first, the basic classification of systems evaluation models was given-summation model, reasons-result model and results-reason model. So the primary problem to select an evaluation function form is to select an additive or non-additive function instead of a linear or nonlinear function. Then, a discriminate theorem was concluded for additive evaluation function that the evaluation function is additive when the indexes are not interactive on the gross index in a system evaluation model.
