In a preferred embodiment, the racking constraint is one of the following:
each type of medicine to be put on shelves can only be placed in the same storehouse position;
only one type of medicine to be put on shelves can be stored in each storage position.
In the above description, a specific implementation process of putting the to-be-put-on-shelf medicines into the turnover putting-on-shelf area according to the order attributes of the medicines in the technical scheme is described. In fact, the above specific implementation process may also be represented by a library allocation model, where the library allocation model specifically has two different constraints, and under the first constraint, the library allocation model is represented as:
wherein
i represents the i-th type of medicine included in the order picking requirement;
j represents the jth drug included in the pick demand;
k represents the bin of the i-th type of drug included in the pick-up demand;
l represents the bin of the jth drug included in the pick-up demand;
It should be noted that, the formula (III) represents a formula corresponding to one racking constraint condition in the above technical solutions, that is, the racking constraint condition is that each type of medicine to be racked can only be placed in the same library position.
Under a second constraint, the library bit allocation model may be expressed as:
wherein the content of the first and second substances,
representing the shortest picking distance;
i represents the i-th type of medicine included in the order picking requirement;
j represents the jth drug included in the pick demand;
k represents the bin of the i-th type of drug included in the pick-up demand;
l represents the bin of the jth drug included in the pick-up demand;
It should be noted that the formula (VI) represents a formula corresponding to another racking restriction condition in the above technical solution, that is, the racking restriction condition is that only one type of medicine to be racked can be stored in each storage location.
In the present invention, the above-established storage allocation model (i.e. the above-described specific implementation process of loading the medicines) can be used to load the medicines to be loaded from the original area to be loaded to the turnover loading area where the medicines can be more easily picked, so that the picking personnel can complete the picking operation of the medicine orders more quickly and with shorter picking distance.
In the technical scheme, an actual measurement and calculation experiment is performed based on the racking system. In a measurement and calculation experiment, 2880 types of medicines to be placed on shelves within 4 months are stored into 2880 storage positions in a turnover placing area from the to-be-placed area through a placing planning result output by the placing system, then a series of medicine orders are provided, and the total path distance = m of the picking personnel to walk for completing picking of related medicines is measured and calculated, and compared with the situation before the turnover placing area is not established, the picking efficiency of the picking personnel for completing picking of related medicines is improved by 25% -30%. And the coverage rate of orders which can finish picking up the orders in the turnover racking area accounting for the total order number is up to 86.24 percent only by measurement, namely the turnover racking area can meet the picking up requirements of most of the medicine orders. In other words, the racking system in the technical scheme optimizes the racking position of the to-be-racked medicines, so that the picking efficiency of picking personnel is improved.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
