Study On Loading Efficiency Boeing B777 Freighter Aircraft

During the incessant development of international trade,air transport industry has been more rapid leap.Especially with the rapid rise of the electricity supplier of products,more and more airlines established an independent air cargo company,will deliver more energy in the freight market,air freight cargo business has grown a new economic rising point in thecivil aviation industry.As an important air cargo carrier China Southern Airlines has entered a single aircraft type fleet scheduling model,that all fly by the B777 F freighters.At this stage,China Southern Airlines cargo plane to fly to Europe and America major international routes,most of the cargo for the rule boxes of goods.However,when China Southern Airlines packing goods,transportation and field assembly of goods,most of them are loaded with experience,scientific slightly less.This manual calculation board arrangement Arranged slow,prone to error,often plate Arranged unscientific,unreasonable assembly,lower space utilization,etc.,thus affecting the removal timeliness and quality of service,it is undoubtedly increased company operating costs,lower income levels.Therefore,study of air cargo in their daily work in the airline's load related topics,to improve the process of modernization of air cargo plays an important role in the application of theoretical value and practical use value is very important.This thesis studies loading problems at home and abroad to carry out an overview,in detail the current use of Southern B777 cargo aircraft models,container board and universal tray circumstances.Secondly,air cargo container loading plate and the actual work of loading problems from container board high school low different categories,container board constraint restrictions aspect,the subject of functions,and so give a systematic analysis.And the establishment of a single model loaded container board container board and multi-load model on this basis;final design of the hybrid algorithm B777 freighter aircraft loading problems: first proposed heuristic algorithm based cargo space to distinguish between,then add sets plates filled genetic algorithm,design Boeing B777 freighter aircraft loading problems China Southern Airlines currently using the hybrid genetic algorithm,and with the use of solving algorithm toolbox.Then by comparing the new algorithm with the current artificial advantages and disadvantages compared to the old algorithm,hybrid genetic algorithm to determine the combination of two algorithms to solve the Boeing B777 freighter aircraft loading problems more reasonable and feasible example checking algorithm initio.Finally,this paper has to give up consideringovercoming some actual problems orpractical considerations,and future research directions and prospects.
