为了合理确定节水灌溉工程方案指标权重,从而对各方案进行科学评价,应用基于单位化约束条件的综合集成赋权法进行指标权重确定计算,并将该方法应用于某节水灌溉工程方案优选中。应用结果表明:与单纯的主观赋权法和客观赋权法以及目前其它已有的综合集成赋权法相比,基于单位化约束条件的综合集成赋权法能够兼顾主客观影响因素,且原理科学、计算过程简便,有较好的实际应用价值。 In order to reasonably determine the weight of water-saving irrigation project index, and then make a scientific evaluation of each program, the integrated weight-integrated method based on unit constraints is used to determine the weight of indicators, and the method is applied to a water-saving irrigation project optimization in. The application results show that, compared with the simple subjective weighting method and objective weighting weighting method and other existing integrated weighting methods currently, the integrated weighting method based on the unitization constraint can take account of the subjective and objective factors and the principle science , The calculation process is simple and has good practical value.
