The Research Of Airline Scheduling Optimization Based On Route Decision-making

Airline scheduling is very important in civil transportation. It defines not onlythe product of Airlines, but also the base of all production plan. Optimal schedulesaim to meet market demands and maximize profits.Civil transportation in the euramerican developed countries has applied a set ofintegrated theory and software products, which has been developed continuously.However, studies and products of internal civil transportation optimization are just atinchoate phase and have few practices, especially overall theory in structuredplanning and optimization process is rare.The paper give the main process of routing decisions and the framework of themodel. including the research of fleet planning, aviation market forecasting model,passengers' demand model and airline route decision model. For the study of theschedule construction is based on airline route decision, the above is ready for furtherresearch on schedule construction and optimization process.The paper carry on an integrated schedule construction process, follow whichall the key points' optimization models are analyzed sequentially. These key pointsare airline frequency and optimization model. Flight schedule timing decision andoptimization model. In timing optimization model, carry on the forecasting flight farediscount rate and the forecasting flight passenger rate instead of common averageflight fare discount rate and the average flight passenger rate. Based on having theaircraft type data in published schedule of civil airlines. Improve the model and thelimited factors with aircraft type, so that make the cost data and revenue data moreexactly. Then following the fleet assignment and aircraft rotation, airline scheduleadjustment. We also make discuss on improving business process and improvingschedule by strategy cost management.The paper discuss the evaluation of airline schedule-timetable, put forward tenevaluation items of airline schedule, which represent the quantity of airlines' serviceproducts. Each items has own evaluate method and quantitative model. The airline scheduling flexibility may be the best feature in this paper.
