Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air freight loading sequence determination system for determining a loading order of containers in an aircraft in a short time to support safe and efficient air freight transportation.

[0002]

2. Description of the Related Art When a cargo such as a container is loaded in an aircraft, the conventional system determines the loading order by manually dividing each container into destinations, target aircrafts, weights, etc. ..

In this case, it is necessary to consider the center of gravity of the aircraft in the order in which the containers are loaded in the aircraft, and therefore it is required that an expert determine the order from the viewpoint of safety.

[0004]

However, in such a conventional air freight loading sequence determination system,
Since the stacking order of each container is manually determined, it takes too much time to determine the optimum order, and there is a problem that only a skilled person can perform this work.

Further, since the center of gravity of the aircraft is taken into consideration and the conditions of the destination of each container and the aircraft to be loaded cannot be taken into consideration so much, it is impossible to make the loading order efficient in and out. There was a problem.

Further, since the time until departure is short, it is not possible to assign an optimum location to the cargo container that arrived just before departure, and the cargo container should be loaded only in an empty space in the aircraft. There was a problem that I could not.

In view of the above-mentioned circumstances, the present invention can determine an optimum loading sequence in a short time when loading each container in an aircraft, and in this way, an optimal loading order can be determined in consideration of the center of gravity of the aircraft and the efficiency of loading and unloading. It is an object of the present invention to provide an air freight loading sequence determination system capable of loading and also freight arriving just before to be loaded at an optimum location.

[0008]

In order to achieve the above object, an air freight loading sequence determination system according to the present invention comprises a container number of a container loaded on an aircraft, a flight number of the aircraft, and a destination of each container. Of these, a data input section that captures the necessary data, and a weighing scale that measures the total weight of the containers loaded with cargo on the aircraft,
A calculation for calculating the loading order that satisfies the specified conditions among the center of gravity of the aircraft, the destination of the container, and the shape of the container based on the total weight of the container measured by this weighing scale and the data input to the data input section. And an output unit for outputting the stacking order obtained by the calculation unit to the outside and stacking the containers in the stacking order.

[0009]

In the above structure, the data input section captures the container number of the container to be loaded on the aircraft, the flight number of the aircraft, and the necessary data of the destination of each container, and the aircraft is loaded by the weighing scale. After the total weight of the container loaded with the cargo to be loaded into the container is measured, the center of gravity of the aircraft is calculated based on the total weight of the container measured by the weighing scale by the calculation unit and the data captured by the data input unit. Of the destinations of the containers and the shapes of the containers, the loading order that satisfies the specified conditions is calculated, and the output section outputs the loading order obtained by the operation section to the outside to load the containers in the loading order. ..
