[0002] At present, the MES system adopted by the salt and salt chemical industry uses a general module for material management. It can only complete simple functions such as routine material warehousing, inventory and outbound delivery. It fails to carry out multi-level and three-dimensional planning of storage locations in view of the characteristics of the salt and salt chemical industry, such as the large variety of salt products, large fluctuations in the storage volume of a single variety, and the need for isolated storage of edible salt and industrial salt. It also cannot automatically allocate storage locations, so that a lot of energy is still needed for manual intervention during storage, the inventory count time is long, the inventory turnover rate is not high, the staffing is large, and the work efficiency is low. Summary of the invention

[0003] The purpose of the present invention is to provide a material management system of MES for salt and salt chemical industry. When the salt and salt chemical industry applies MES system to intelligently manage salt-making factories, the production management mode is more in line with the habits of salt and salt chemical industry.
