摘要：

在高速送料机可靠性分配的问题中，存在模糊因素较多难以定量分析的问题。针对这一问题，将多级模糊评判和区间层次分析法相结合，并依赖专家经验和实际记录数据，提出一种高速送料机的可靠性综合分配方法。首先，使用区间层次分析法量化模糊信息，在此基础上，再结合多级模糊评判评价各个待分配的子组件可靠性水平。最后，通过以上方法对高速送料机的可靠性指标进行线性分配，并结合实例对该方法进行了验证。结果显示，运用区间数替代具体数值来表示模糊信息，可使得专家评估的分数更能反应现实情况。同时，结合实际记录的数据进行可靠性评价，使得分配结果更加符合客观实际。将这种方法用于解决高速送料机或同类型产品的可靠性分配问题是可行的。

Because of many fuzzy factors, the quantitative analysis of reliability of high-speed feeder allocation is difficult to carry out. For this problem, a comprehensive reliability allocation method for high-speed feeding machine was proposed combining the multi-stage fuzzy assessment with the interval analytic hierarchy process (IAHP) and depending on the experts experience and the actual recorded data. First of all, the interval analytic hierarchy process was used to quantify the fuzzy information, and then, the relative reliability level of each subcomponent was evaluated by the multilevel fuzzy assessment. Finally, the reliability index of high-speed feeding machine was linearly allocated by the above method, and the experiment was given to verify the method. Results show that the interval number used to represent the fuzzy information insteading of the specific value can make the expert assessments cores more realistic. Meanwhile, the reliability evaluation combined with the actual recorded data makes the allocation result more according with the objective reality. In summary, this method can be used to solve the reliability allocation problem of the high-speed feeder or similar products currently.
