A kind of air cargo mail distribution method

Abstract

Disclosed is an air cargo delivery method, comprising the following steps: step one, acquiring flight data and cargo order data; step two, sorting flights of the same flight segment on the same day in a sequential order of departure times; step three, establishing, for the delivery of all cargo orders in the same flight segment on the same day, a secondary target plan model taking the degree of urgency of delivery as a target, wherein a constraint condition thereof includes an adjustment parameter β; and step four, iteratively adjusting the value of β, solving the secondary target plan model after each iteration, and establishing a primary target plan model taking the balance of flight utilization rates as a target, so as to determine an optimal scheme solved and obtained in an iteration process. In the method, the degree of urgency of delivery of cargo orders and the balance of flight utilization rates of the same flight segment are comprehensively taken into consideration, thereby achieving double-target optimization in an air cargo delivery process.

Description

technical field [0001] The invention belongs to the technical field of aviation, and in particular relates to an air cargo mail distribution method. Background technique [0002] With the development of economic globalization, air transport business has also been greatly developed. According to the 2017 Civil Aviation Industry Development Statistical Bulletin, as of the end of 2017, China had a total of 229 certified transport airports, an increase of 11 from the end of the previous year; the revenue level of cargo and mail transportation in 2017 reached 1.48 yuan / ton km, an increase from the previous year. 0.15 yuan / ton km. With the rapid development of China's air cargo and mail transportation business, there will inevitably be many problems that cannot be ignored. In the current air transport fleet, the total number of civil aviation cargo planes in China is 143, accounting for only 4.34% of the total number of transport planes, and passenger planes account for 95.66% o...

AI Technical Summary

Problems solved by technology

[0004] (2) There is a situation where the flight departure time is fixed but the loading time of the cargo mail order is not fixed

The proportion of agency sales and free sales of cargo and mail orders is generally judged by airlines through experience, and has certain limitations for routes with complicated flight segments

[0006] (4) Air cargo and mail orders do not give priority to high value-added cargo and mail orders such as express mail and urgent mail

[0007] The rationality of the delivery method of cargo and mail will directly affect the overall development of the logistics industry. Most of the existing methods are to establish an air cargo and mail distribution model through the research of cargo and mail agents, without considering the impact of free sales orders on the air cargo and mail business. and the goal to achieve is relatively single, focusing on maximizing revenue, and it is impossible to optimize the balance of flight utilization on the same flight segment, where flight utilization = total weight of flight cargo / flight operation availability; there are many types of orders, and there is no Cargo and mail orders are classified, and the same batch of goods with higher time value is not given priority delivery. The same batch of goods with higher time value refers to the value comparison per unit time among the goods shipped on the same flight segment on the same day Goods with high timeliness; in air cargo, the time value of general urgent and express mail is the highest, and the added value of perishable goods is the second highest
