The invention discloses a three-dimensional multi-box specially-structured cargo loading optimizing method. The three-dimensional multi-box specially-structured cargo loading optimizing method comprises the steps that a plurality of containers A are selected as containers to be loaded, spaces of the containers A serve as initial spaces, and the
list of cargoes which can be loaded and basic
data information of the cargoes are determined according to the initial spaces; sequencing is carried out in a descending order mode according to priority attribute values, T primary branches are generated, the initial j is set to be equal to one, the j is larger than or equal to one and is smaller than or equal to T, loading calculation of the containers A is carried out on the jth primary
branch until loading calculation of all the T primary branches is accomplished, an optimal scheme is selected, the classifications of the cargoes, the placement direction of the cargoes, the number of the cargoes and position information of the cargoes in the optimal scheme are recorded, and the number of cargoes to be loaded is updated; if more cargoes to be loaded exist, the number of the classifications of the cargoes to be loaded is integer N times that of the cargoes in the reserved optimal scheme result, and the corresponding amount of the cargoes to be loaded is integer N times that of the cargoes in the reserved optimal scheme result, N
stowage results same as the optimal scheme are generated; if not, switching is carried out, and recomputation is started until all the cargoes is completely loaded. The three-dimensional multi-box specially-structured cargo loading optimizing method has the advantages that the speed of an
algorithm is high, the
utilization rate of the spaces of the containers is high, and the three-dimensional multi-box specially-structured cargo loading optimizing method can be better applied actually.
