Abstract
The invention discloses a cargo location optimization method of an automatic three-dimensional warehouse of a pharmaceutical enterprise and a system thereof. The method is characterized in that through determining a cargo location optimization target of an automatic three-dimensional warehouse, a medicine delivering-and-warehousing frequency is calculated according to historical order data of medicines in the automatic three-dimensional warehouse; an association factor between the medicines is obtained according to the association degree between the medicines; a piler motion mathematical modelis established; and according to the piler motion mathematical model, the medicine delivering-and-warehousing frequency and the association factor between the medicines, a multi-target cargo locationoptimization mathematical model is established and the multi-target cargo location optimization mathematical model is calculated, thereby obtaining a cargo location optimization result. The method and the system settle problems of incapability of well describing an actual problem and non-ideal optimization result caused by only consideration of cargo turnover rate and shelf stability. Furthermorethe method and the system have advantages of realizing more ideal cargo optimization result obtained through calculation based on the multi-target cargo optimization model and more reasonable cargo distribution, greatly improving warehousing efficiency and reducing warehousing operation cost.
Description
technical field [0001] The invention mainly relates to the technical field of logistics storage, in particular to a method and a system for optimizing the location of an automated three-dimensional warehouse of a pharmaceutical enterprise. Background technique [0002] With the continuous improvement of the overall level of the supply chain in the pharmaceutical industry and the continuous strengthening of industry standards (GMP / GSP), pharmaceutical logistics has become a key area of logistics automation. As an important part of modern logistics, automated three-dimensional warehouse adopts mechanized operation and information scheduling, which has the advantages of saving labor, improving storage management level, and reducing logistics costs. It is an advanced storage mode widely recognized by the society and is widely used in enterprise storage. . The automated three-dimensional warehouses of pharmaceutical companies are connected to the production workshops through a...
