路网规划评价中评价因素的权重确定是应用中的难点,采用同时确定因素权重和方案隶属度的模糊迭代方法较好解决因素权重值计算,由于决策者推荐方案中隐含的决策意图,使排序结果更为客观和合理,避免了实际工作中因素权值确定的不客观性,显著提高了决策效果. The determination of the weight of the evaluation factors in the evaluation of road network planning is a difficult point in the application. The fuzzy iteration method of determining the weight of factors and membership of the scheme is better to solve the calculation of the weight of factors. Because of the implicit decision intent in the recommendation scheme of decision makers, The sorting result is more objective and reasonable, avoiding the objectivity in determining the weight of factors in actual work and significantly improving the decision-making effect.
