Abstract The structures of the airport pavements are designed for defined operational time, assuming the predicted intensity and structure of the air traffic. The safety of air operations conducted by aircrafts on airport pavements depends mostly on their load capacity and design. Therefore, the load capacity inspections should be performed periodically, as the information about the current operational condition of the airport pavement is the basis for decisions on types of aircrafts allowed for traffic, as well as traffic intensity and dates of renovation or modernization works. Currently, the load capacity of airport pavements is assessed with the use of the ACN-PCN method, implemented by the ICAO (International Civil Aviation Organization). This article presents the method of determination and description of the PCN index

The Aircraft Classification Number-Pavement Classification Number method is the main approach for evaluating the structure of the airport pavement. However, the weakness of exiting methods lies in the difficulty of obtaining the exact PCN of the airport from the Airports Authority. This paper investigated the attenuation behaviors of the pavement structure under the envrionment of aircraft operation, and then the improved evaluation method for airport pavement was presented. The improved method could provide the technical support for accurately judging the bearing capacity of the exiting pavement structure and supply the decision-making reference to the Airports Authority.

With the rapid development of China’s market economy, brand image is becoming more and more important for an enterprise to enhance its market competitiveness and occupy a favorable market share. However, the brand image of many established companies gradually loses with the development of society and the improvement of people’s aesthetic pursuit. This has forced it to change its corporate brand image and regain the favor of the market. Based on this, this article combines the related knowledge and concepts of fuzzy theory, from the perspective of visual identity design, explores the development of corporate brand image visual identity intelligent system, and aims to design a set of visual identity system that is different from competitors in order to shape the enterprise. Distinctive brand image and improve its market competitiveness. This article first collected a large amount of information through the literature investigation method, and made a systematic and comprehensive introduction to fuzzy theory, visual recognition technology and related theoretical concepts of brand image, which laid a sufficient theoretical foundation for the later discussion of the application of fuzzy theory in the design of brand image visual recognition intelligent system; then the fuzzy theory algorithm is described in detail, a fuzzy neural network is proposed and applied to the design of the brand image visual recognition intelligent system, and the design experiment of the intelligent recognition system is carried out; finally, through the use of the specific case of KFC brand logo, the designed intelligent recognition system was tested, and it was found that the visual recognition intelligent system had an overall accuracy rate of 96.08% for the KFC brand logo. Among them, the accuracy rate of color recognition was the highest, 96.62%; comparing the changes in the output value of the training sample and the test sample, the output convergence effect of the color network is the best; through the comparison test of the BP neural network, the recognition effect of the fuzzy neural network is better.
