简介:摘 要:根据炮兵武器射击的原理和影响毁伤的因素分析,建立了炮兵武器毁伤效能评价指标体系。利用信息熵的理论和方法对各项指标赋权值,克服了以往评价指标确定权值的主观性,使权重更科学、合理。并通过具体实例建立模型,验证其可靠性。
简介:摘要:文中旨在开发一个适用于设备风险影响因素的定量评价方法,以此来弥补传统TOP10管理方法带有较大的人为因素影响。通过采用基于AHP-模糊综合评价方法进行评价,结合本项目的特点,建立设备供货风险评价指标体系。该体系包含3个一级指标,14个二级指标。通过设计问卷,专家评判数据,分析指标权重,隶属度,最终得出风险等级,为项目风险点管控提供数据依据。结果表明,该方法具有较好的实用性和可操作性。
