Comprehensive Evaluation Model of Grey Fixed Weight Clustering for Airport Pavement Service Performance

Evaluation of airport pavement service performance provides decision-making reference for management and scheme of design and maintenance. In order to evaluate airport pavement service performance, the evaluation index system and standard for airport pavement service performance are constituted, and the index weight value is confirmed using fuzzy consistent theory according to comparative importance of the index. The grey clustering method is adopted to fulfill comprehensive evaluation of airport pavement service performance by way of confirming of white function of grey clustering and constitution of clustering row vector. The service performance evaluation grade is showed by the single comprehensive index method and the state vector method, which can make it easy both to arrange the result in an order and analyze the cause of the result. Analysis result of an example shows the PCI and SFC is the major causation influencing the pavement performance, the example airport pavement performance dropped to grade III, and the maintenance scheme is to repair the pavement surface and friction.
