Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, not to limit the present invention.

[0015] The present invention provides an optical network evaluation method, which includes the following steps: Step 1: Construct a network evaluation model based on AHP based on evaluation factors to be used, factors and criteria affecting targets, and comprehensive evaluation formulas; Step 2 : Fill in the pairwise comparison matrix A=(a ij ) n×n , where a ij is the ratio of the impact of the i-th factor to the j-th factor on the upper factor, where n is the number of rows and columns of the paired comparison matrix; Step 3: Determine the eigenvector w and the largest eigenvalue λ of the paired comparison matrix; Step 4 : Carry out the consistency check, if it passes the ...

Abstract

The present invention discloses an optical network evaluation method including the steps of building an AHP-based network evaluation model based on a necessary evaluation factor, an factor and a guideline influencing a target and a comprehensive evaluation formula; completing a pairwise comparison matrix that A is equal to (aij) n x n, where aij is the ratio of influence of an i-th factor on top factors to influence of an j-th factor on top factors in an n-th layer; determining an eigenvector w and a maximum eigenvalue [lambda] of the pairwise comparison matrix; carrying out a consistency check, and proceeding to step five if the consistency check is passed, or returning to step two if the consistency check fails; calculating a combination weight vector w(s) according to the eigenvector w and carrying out a combination consistency check; and carrying out a comprehensive network evaluation according to the combination weight vector w(s). The optical network evaluation method has the characteristics of accuracy, flexibility and high adaptability.

Description

technical field [0001] The present invention relates to the communication field, in particular to an optical network evaluation method. Background technique [0002] As the basic network that provides communication services, the optical network is responsible for transmitting more than 80% of the circulating information in the communication network, and its quality plays a vital role in the communication services carried. Therefore, it is very necessary to evaluate and analyze various problems existing in the optical network, and put forward targeted suggestions for network construction and rectification. [0003] Some of the current evaluation methods only focus on one evaluation indicator, and the obtained evaluation results are often too one-sided to evaluate the network comprehensively. Another part of the evaluation method is aimed at multiple evaluation indicators, which is a comprehensive consideration of multiple indicators. Existing multi-index evaluation methods ...
