阵地建设工程装备保障能力评估

Support Capability Assessment for Engineering Equipment of Position Construction

为研究阵地建设工程装备保障能力评估的问题,找到与担负建设任务保障能力需求的差距,在构建指标体系的基础上,建立基于置信规则库的装备保障能力评估模型,解决带有模糊不确定性、概率不确定性以及非线性特征的底层指标聚集和证据推理问题。针对底层指标增多而出现组合指数增多的问题,提出基于并集假设的置信规则库推理模型。研究结果表明:基于置信规则库的工程装备保障能力评估模型,能很好糅合多属性底层指标、缩小置信规则库规模、降低评估过程复杂度,减少底层指标在逐层聚集过程中信息衰减问题。

In order to study the evaluation of engineering equipment support capability of position construction and find out the gap between the requirement of equipment support capability of undertaking construction task.Based on the construction of index system,the evaluation model of equipment support capability based on belief rule base is established to solve the aggregation and evidence reasoning problems of fuzzy uncertainty,probability uncertainty and non-linear characteristics layer index.Aiming at the problem of increasing combination index with the increase of underlying indexes,a reasoning model of belief rule base based on union hypothesis is proposed.The result shows that the evaluation model of engineering equipment support capability based on belief rule base can well integrate multi-attribute bottom indicators,reduce the scale of belief rule base,reduce the complexity of evaluation process,and reduce the information attenuation problem of bottom indicators in the process of layer-by-layer aggregation.
