【摘要】 从投入产出方面进行方案的优选,指出数据包络分析特别适用于具有多投入多产出特点的复杂系统.提出了用DEA中的C2R模型对水利工程方案进行优选,从求解结果来看,不仅能找出DEA有效的方案,还能发现非DEA有效方案中存在的问题,并提出解决方法.更多还原

【Abstract】 This paper optimizes project schemes from input-output aspect.Because DEA is especially suitable for complex system with multiply input-output,this paper applies model to optimize water resources project schemes.Analyzing computation results,both efficient DEA schemes and problems which leads to inefficient DEA schemes can be found,so that solutions can be put forward.更多还原
