The application discloses a civil aviation logistics intelligent loading system based on adaptive constraint relaxation, which comprises a data input and preprocessing module, a constraint multi-objective modeling module, a three-population collaborative evolution optimization module and a scheme output and application module. The data input and preprocessing module is used for extracting multi-source data required by a loading task from an airline operation database, arranging and converting the data into a system readable format, loading the data into a system cache area and completing data preparation of a model. The constraint multi-objective modeling module is used for constructing a constraint multi-objective optimization model of the civil aviation logistics intelligent loading based on the data output by the data input and preprocessing module. The three-population collaborative evolution optimization module adopts a three-population collaborative evolution algorithm ThcAp as a core solver. The application has more flexible and intelligent constraint processing, stronger multi-objective optimization capability, higher algorithm robustness, better scene adaptability, significantly improved loading efficiency and comprehensive benefits.

The application relates to the field of civil aviation technology, and relates to a planned maintenance work cost evaluation method and system for a supplier SB / SIL. The evaluation method comprises the following steps: S1, establishing a basic cost motive identification database; S2, establishing an SB / SIL storage analysis database module; S3, calculating and measuring total cost; and S4, outputting a quantitative analysis suggestion report corresponding to whether an SB / SIL maintenance item is implemented. The evaluation system comprises a basic cost motive identification database module, an SB / SIL storage analysis database module, an algorithm matching accounting module and an evaluation report generation module. The planned maintenance work cost evaluation method and system for the supplier SB / SIL can improve the judgment accuracy of whether maintenance work is implemented by a planning maintenance engineering department of an airline, thereby being favorable to saving maintenance costs of the airline, avoiding safety hazards and improving the reliability and safety of airline operation.
