基于变权系数的GIS运行状态多层模糊综合评判
|
摘要
评估GIS运行状态通常采用基于层次分析法的多层模糊综合评判方法,该方法未充分考虑某些评价因素的变化程度不同时对评判结果的影响程度的差异,降低了评估结果的可靠性。为提升GIS评估结果的可靠性,文中提出采用变权系数的多层次模糊综合评价模型,综合GIS工作环境、外观情况、维修状态、生产厂家和附件情况等建立GIS层次型评估指标体系,在常权权重的基础上引入均衡函数的变权模式修正各指标权重系数,利用模糊统计法和模糊分布法确定各指标的隶属函数,通过各影响因素状态、模糊权重矩阵融合各评价因素的隶属函数,评估对各层评价因素,综合得出GIS的运行状态。经实例分析表明,变权系数的多层模糊综合评估模型较层次分析的多层模糊综合评判可有效平衡各影响因素之间关系,实现GIS运行状态准确有效评估,为GIS维修决策的制定提供一定的参考。
The evaluation of the running state of GIS is usually based on the analytic hierarchy process(AHP).However,the method does not consider the impact of some factors changing obviously or not.In this paper,a multi-level fuzzy comprehensive evaluation model with variable weight coefficient is proposed.It integrates the GIS working environment,appearance,maintenance status,manufacturers and accessories to establish a hierarchical evaluation index system to improve the accuracy of the GIS operation state evaluation.The model first uses the analytic hierarchy process to determine the weights of the evaluation indexes in the evaluation model,and introduces the variable weight model of the equilibrium function to the constant weight correction.The membership function of each index is determined by fuzzy statistics and fuzzy distribution.The fuzzy weight matrix is used to fuse the membership functions of each evaluation factor,and the evaluation factors are evaluated respectively,and the running state of GIS is comprehensively obtained.The example analysis shows that the evaluation model can realize the accurate and effective evaluation of GIS running state,and the evaluation results can provide scientific basis for equipment operation and maintenance management.
