Communication network comprehensive performance evaluation parameter weight determination and adjusting method

Abstract

The invention provides a communication network comprehensive performance evaluation parameter weight determination and adjusting method. The method includes: firstly, calculating a fixed weight of a communication network comprehensive property evaluation parameter by employing an improved analytic hierarchy process based on a communication network comprehensive performance evaluation parameter system; and then adjusting the weight of the evaluation parameter by employing a variable weight algorithm based on historical data and expert experience information on the basis of basic data of the calculated fixed weight, and finally obtaining a final index weight. According to the method, the calculated fixed weight depending on expert experience is adjusted by employing the historical data, the expert opinions are fully respected, the historical information is reasonably utilized, the final weight can be scientific and reasonable, the effectiveness and the reliability of network comprehensive performance assessment results are improved, by employing the method, the revision of the index weight in an index system does not need reorganization of experts for evaluation, only the best ideal value and the worst ideal value of each index after multiple years are given, and the assessment cost is greatly reduced.

Description

technical field [0001] The invention relates to a method for determining the weight of a wireless communication network comprehensive performance evaluation parameter and adjusting it, and belongs to the technical field of communication. Background technique [0002] Comprehensive performance evaluation of wireless communication networks not only helps to integrate advantageous communication resources, improve overall performance, provide reference for system design, optimization, operation and maintenance, but also provide scientific decision-making basis for network managers and operators. To evaluate the comprehensive performance of the network, it is necessary to comprehensively consider the status of multiple indicators including received signal strength, network quality of service (Quality of Service, QoS) and network load to obtain the result of comprehensive performance evaluation. [0003] Comprehensive performance evaluation mainly involves three key steps: index s...

Problems solved by technology

[0004] 1) The final calculated indicator weights cannot be adjusted according to historical statistical data, and only fixed weights are used for comprehensive performance evaluation, which may cause distortion of the evaluation results

[0005] 2) The existing weight adjustment methods such as penalty-type weight change, incentive-type weight change and local weight change are mainly adjusted for the evaluation results, not for the weight adjustment. The rationality of the weight change is poor, and it is difficult to adjust the adjusted weight. give a reasonable explanation

[0006] 3) Due to the continuous progress of science and technology, it is necessary to re-revise the weights of the indicators in the network comprehensive performance evaluation parameter system at regular intervals, and the existing weight calculation method needs to reorganize experts to evaluate the importance of indicators in pairs. The process is time consuming
