To improve utilization of space of logistic distribution

reduce costs and improve efficiency

modified cultural algorithm for 3D space optimal loading method is proposed.According to characteristics of loading problems

take multiple constraints into account

a multi-constrained and multi-objective mathematical model is established

the single belief space of cultural algorithm is improved to multilayer.This algorithm improves computing performance and speed of evolution through the experience selected from multi-layer belief space

and keep good performance of wide searching range.Simulation result proves that the algorithm produces better result

more efficient and faster than traditional algorithms in solving 3D container loading problem

applicability is good.
