对多目标决策可从不同角度加以分类,目前国内外较为普遍的分为目标优化决策和多属性决策。前者有无限多个备选方案,这些方案隐含于所建由连续变量组成的数学模型之中,通过解数学模型寻求方案优化,属设计性决策,如工程上的优化设计等;后者是在有限个显性离散型方案中选优或按方案优劣排序,属选择评价性决策,如基建工程择优招标等。第二次世界大战以后,出现了由定性决策向定量决策发展的趋势。人们致力于用数学模型来描述多目标问题的机理,把近代数学和电子计算机用于决策,成功地创造了诸多的决策数学模型,把许多常规决策模式化、程序化了。这不仅大大提高了决策速度、
Multi-objective decision-making can be classified from different perspectives, the current more common at home and abroad are divided into objective optimization and multi-attribute decision-making. The former has an unlimited number of alternatives, these programs are implicit in the construction of a mathematical model consisting of continuous variables, by solving the mathematical model to seek optimization programs, is a design decision, such as engineering optimization design; the latter is In a limited number of dominant discrete programs or programs according to the merits and demerits, is the choice of evaluation decisions, such as infrastructure projects such as merit bidding. After World War II, there has been a trend of developing from qualitative decision to quantitative decision. People are devoted to using mathematic models to describe the mechanics of multi-objective problems, using modern mathematics and computers for decision-making, and successfully creating numerous mathematical models for decision-making that model and program many common decisions. This not only greatly improves the speed of decision-making,
