Abstract

For increasing accuracy rate of landing risk assessment of carrier-based aircraft, this article is committed to research on landing risk assessment of carrier-based aircraft based on mean-variance dynamic multi-attribute decision making. Attribute values are provided in the form of triangle fuzzy number. Mean sort values is acquired by formula of possibility degree and order. For solving a problem of the same or similar orders, the improved method combines mean and variance, analyzing and judging, getting alternatives rank. Finally, the feasibility and availability of the improved method is proved by simulation results.

Carrier-Based Aircraft Landing System Model

In order to provide time weights and simulation data for landing risk assessment of carrier-based aircraft based on multi-attribute decision making, carrier-based aircraft landing system model is necessarily built, as shown in Figure 1 (Zhu & Li et al., 2012).

Figure 1.

Carrier-based aircraft landing system model

Generally speaking, for landing system of carrier-based aircraft which is shown in Figure 1, landing risk evaluation should be realized as Figure 2 by four steps:

  • 1.

    Explicit four evaluation positions: start position (X), middle position (IM), close position (IC) and ramp position (AR);

  • 2.

    Obtain decision making records of flight status information at different positions;

  • 3.

    Make certain discrete time of four standard positions;

  • 4.

    Dynamic decision making with decision information using appropriate ways.
