摘　　要：通过分析影响煤矿机械可靠性的各种因素,建立煤矿机械可靠性评价体系,采用不确定语言变量来描述评价指标属性权重和属性值,通过定义ULWM算子,结合ULHA算子对煤矿机械的可靠性进行评价及实例分析,为煤矿机械设备的安全生产和科学决策提供了依据。Builds a reliability evaluation indexes system of colliery machine based on a comprehensive analysis of the factors influencing the reliability of colliery machine. A new method with uncertain linguistic variable of the attribute weights and attribute values based on the ULIVM operator and ULHA operator is used to evaluation the reliability of colliery machine. An example shows the scientifieity of this method, it provides a evidence for security produce and scientific decisionmaking of colliery mechine.
