Abstract: The intelligent warehouse has an important role for improving storage utilization ratio and production efficiency in modern enterprises. This article described the location allocation intelligent algorithm of threcdimensional Warehouse Management System of Qinhuangdao Port Group Co. Ltd, this algorithm fully takes into account the factors of weight evenly distributing, the nearest bin location options, spare parts species evenly distributing, spare parts usage ratio, the empty time of a bin etc, computes the bin location of storage according to the current state of whole warehouse, and provides decision support for the bin location option. The actual project operation shows that the proposed integrated bin location optimization allocation algorithm is effective, and has very important significance for improving the safety of warehouses, storage efficiency and so on.

Key words: Three-dimensional warehouse, I3in location allocation algorithm, Weight evenly distributing, Spare parts species evenly distributing,Principles of the nearest bin location options
