Abstract

In order to improve the level of credibility and intelligence of efficiency evaluation, a BP neural network effectiveness evaluation frame of data link system on the basis of gray AHP theory was proposed.Considering performance and structure of data link system, according to the characteristics of advantage of data link information, the operational effectiveness assessment index system of data link was established.Through expert marking by standard, using AHP to determine the weight vectors of index, considering to use the albino indicators index of gray theory aggregate with different gray class efficiency value to generate comprehensive efficiency evaluation so that the output efficiency model was established.A three-layer BP neural network model was structured with the expert's knowledge and experience as input, and the grey AHP comprehensive efficiency evaluation value as the output of the training network.Finally, the experiment validated that the result was consistent with the expert evaluation.Since the model uses the advantage of nonlinear fitting inheritance of BP neural network and aggregates the expert's knowledge and experience effectively, therefore, it demonstrates validity and reliability of the model and provides intelligent operator for the data link system effectiveness evaluation.The model plays an important role in development and application of the data link.

Key words： data link system; index system; gray system model; analytic hierarchy process; BP neural network
