A Determination and Adjustment Method of Parameter Weights for Comprehensive Performance Evaluation of Communication Networks

Abstract

A method for determining and adjusting the weight of a communication network comprehensive performance evaluation parameter, said method is based on establishing a communication network comprehensive performance evaluation parameter system, firstly adopts an improved analytic hierarchy process to calculate the fixed weight of the communication network comprehensive performance evaluation parameter; and then Based on the calculated basic data with fixed weights, the weights of the evaluation parameters are adjusted using a variable weight algorithm based on historical data and expert experience information to obtain the final index weights. The present invention uses historical data to adjust the fixed weights obtained by relying on expert experience, which not only fully respects expert opinions, but also makes reasonable use of historical information to ensure that the final weights obtained are scientific and reasonable, thereby improving the effectiveness of network comprehensive performance evaluation results and reliability. Using this method to revise the index weights in the index system does not need to reorganize experts for evaluation, but only needs to give the ideal best value and ideal worst value of each index after several years, which greatly saves the evaluation cost.

Description

technical field [0001] The invention relates to a method for determining and adjusting the weight of a comprehensive performance evaluation parameter of a wireless communication network, and belongs to the technical field of communication. Background technique [0002] Comprehensive performance evaluation of wireless communication network not only helps to integrate superior communication resources, improve overall performance, and provide reference for system design, optimization and operation and maintenance, but also provides 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 service quality (Quality of Service, QoS) and network load to obtain the comprehensive performance evaluation result. [0003] The comprehensive performance evaluation mainly involves three key steps: the ...

AI Technical Summary

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
