Abstract

Quality of Experience (QoE) becomes recently the most important tendency to guarantee the quality of telecommunication services. In this paper, we proposed a three-step approach to calculate the weights of KPIs in the KQI (Key Quality Indicators) / KPI (Key Performance Indicators) assessment architecture for QoE evaluation. First, indicators are classified into two sets (Static Set and Dynamic Set) according to their change degree represented by their standard deviation. Second, for indicators in dynamic set, a changes-sensitive method for calculating dynamic weights (CMDW) is proposed, which takes into account not only the relative importance but also the change of the indicators. And for indicators in static set, we use a subjective method to get the corresponding weights. At last the weights of indicators in the two set are combined. As a result, the weights determined using the proposed method can not only combine subjective and objective information but also reflect the change of the indictors on QoE evaluation.

一种面向qos的电信业务指标动态权重计算方法

体验质量(Quality of Experience, QoE)是保证电信服务质量的重要趋势。在本文中，我们提出了一种三步法来计算关键质量指标(KQI) /关键绩效指标(KPI)评估体系中关键绩效指标的权重。首先，根据指标的标准差所代表的变化程度，将指标分为静态集和动态集两组。其次，对于动态集中的指标，提出了一种既考虑相对重要性又考虑指标变化的动态权重计算方法(CMDW)。对于静态集的指标，我们采用主观的方法得到相应的权重。最后对两组指标的权重进行合并。因此，采用该方法确定的权重既能将主观信息与客观信息相结合，又能反映质量oe评价指标的变化情况。
