Abstract:

In order to understand the current development level and research progress of aircraft weight and balance (AWB), and provide reference for the subsequent research and application of loading technology, the concept of weight, center of gravity(CG) and center of gravity envelope is introduced firstly. Secondly, three research directions of air cargo loading are summarized, including cargo transportation planning, cargo packing, container loading balance.

And container loading balance is divided into heuristic method and (mixed) integer linear programming method according to the time process. Then, the development and application status of the loading technology are intro鄄 duced, the development process of the AWB are summarized and analyzed, and the application of the loading technology is divided into three stages of manual AWB, computer-aided AWB and automatic AWB. Through the literature review, it is found that the recent research on loading adopts the simplified target center of gravity devia鄄 tion constraint, resulting in a large gap between the research and the practical application. Finally, the prospect of the loading technology is proposed, stating that the future loading technology will be based on the actual center of gravity envelope, transitioning from the enumeration method to the integer planning method, gradually achieve loading optimization, and integrate machine learning and other technologies into company preferences and operat鄄 ing experience to achieve intelligent loading scheme belongs to airline preferences.

Key words: air transportation, load balancing, cargo transportation, transportation planning, packing problem
