Embodiment one：
Fig. 1 shows the flow of medical electric business mirror image picking method provided in an embodiment of the present invention, for convenience of description only
Show the part related to the embodiment of the present invention.
The medical electric business mirror image picking method that the present embodiment is provided comprises the steps：
When being filled at the beginning of step S1, data, it is that mirror image chooses region, the mirror image that picking operation region is set in WMS systems
At least two, region is chosen, the selection of each mirror image is connected between region by power transmission line.
WMS warehouse management systems are the conventional logistic management systems of logistic industry, and completion is put in storage, chosen, checking, outbound
Etc. it is a series of control management processes.In current logistics center, storehouse volume is very big, the commodity stocks category of each storehouse and
Data are all very big, therefore cause the distance between every kind of commodity also than larger, and when order comes then, selection personnel pick according to order
Choosing, when type of merchandize is more in order, selection personnel need great distances of walking about, and choose inefficient.And when order is big
When amount is issued, multiple tasks selection also influence selection efficiency is carried out in a storehouse.
The present embodiment sets multiple mirror image selection areas for this, and in an initial condition, commodity choose region base in each mirror image
Originally it is evenly distributed, it is ensured that commodity there are enough stocks in each region, meets in a mirror image cell selection, subtract as far as possible
The travel distance of few warehouse personnel.Therefore first in this step, when being filled at the beginning of data, multiple mirrors are set first in WMS systems
As selection region, the selection of each mirror image is connected between region by power transmission line, as shown in Fig. 2 for the ease of display, Fig. 2
In only list two mirror images selection regions, more mirror images selection regions can essentially be set.
Step S2, one is often received when commodity ex-warehouse order, according to selection rule and combine commodity in different mirror images
Inventory locations, stockpile number and the outbound principle in region are chosen, picking task is initiated in mirror image selection region thereto.
After client places an order, WMS systems, which can be generated, can a commodity or multiple on a commodity ex-warehouse order, order
Commodity, and every kind of commodity selection quantity.After order is received, selection rule is provided with system and mirror image selection is combined
Initiate selection task in inventory locations, stockpile number and the outbound principle in region, the suitable mirror image selection region of selection one.By
It is endlessly, to be divided into multiple mirror image selection regions and chosen, regional can be performed parallel, can be obvious in order
Improve selection efficiency.The present embodiment is tried one's best to meet and chosen in a mirror image selection region, can shorten the walking of picking personnel
Time.
Enumerated as a kind of example, this step is specifically included：
S21, when receiving a commodity ex-warehouse order, from each mirror image selection region in filter out institute in current order
There are commodity to be satisfied by the mirror image selection region of inventory concerns；
S22, the Order splitting value for calculating each mirror image selection region filtered out：
Y=K1*M+K2*N+K3*R
WhereinHere letter
In number f (x), the f (x)=0 when x is less than or equal to 1, the f (x)=1, M when x is more than 1iBe in order i-th commodity current
Stockpile number in mirror image selection region, Mi0It is i-th quantity to be chosen of commodity, MXiIt is that i-th commodity chooses area in mirror image
Stock's lower limit in domain, N is represented when each mirror image chooses the busy degree in region, if ordering of being presently processing of mirror image selection region
When odd number amount is more than or equal to preset value, N=0, otherwise N=1, R represents each commodity of order shelf in mirror image selection region
The how far apart from sum of position, the R values in the T mirror image selection region nearest apart from sum are 1, and other are 0, here T
The half of region sum is chosen for mirror image and is rounded, K1、K2、K3It is proportionality constant；
Picking task is initiated in the maximum mirror image selection region of S23, selection Order splitting value, if Order splitting value maximum
Mirror image selection region has multiple, then the number order for choosing region according to mirror image selects first mirror image selection region to initiate picking
Task；
If S24, satisfactory mirror image selection region can not be filtered out, selectValue maximum
Mirror image chooses region and initiates picking task, ifThe maximum mirror image selection region of value has multiple, then according to
The number order in mirror image selection region selects first mirror image selection region to initiate picking task.
Here M, N, R value are 0 or 1, M illustrate the influence of commodity stocks amount, and N illustrates each mirror image selection region
Busy degree influence, R represent each commodity of order mirror image choose region in shelf location influence, as far as possible select one
Commodity stocks amount it is big, it is relatively more idle, reduce selection personnel as far as possible and walk about the mirror image selection area of distance.
During selection, what is considered first is to try to the selection in a selection region, therefore chooses area from each mirror image first
The mirror image selection region that all commodity in current order are satisfied by inventory concerns is filtered out in domain, that is, filters out all business in order
In mirror image selection region, all target mirror picture chooses region to product in stock, can thus avoid follow-up relay from choosing.
Mirror image selection region is being filtered out, the present embodiment is determined most by calculating the Order splitting value Y in each region
The mirror image of selection chooses region eventually.For i-th of commodity of order, every commodity have one in each mirror image selection region
Stock's lower limit, Mi-Mi0Represent that stock deducts commodity in order and chooses remaining inventory after quantity, ifIt is less than
Or equal to 1, illustrate the remaining inventory of the commodity after deducting already less than or equal to stock's lower limit, it is not recommended that to select this mirror
As selection region, to ensure that each commodity have certain quantity in stock in region, to reduce reorder frequency.If M=1, illustrate this
Commodity stocks is deducted after the selection quantity in order in individual mirror image selection region, still more than stock lower limit.N illustrates each mirror
As the influence of the busy degree in selection region, there is an order processing thresholding in mirror image selection region, such as quantity on order is less than
At N0, normally can quickly it handle, order processing efficiency just has an impact after more than N0, therefore in the present embodiment, mirror image
When the quantity on order that is presently processing of selection region is more than or equal to preset value N0, N=0, otherwise N=1.In addition, selection people
Walk about distance of the member in selection region is also influence factor, and the merchandise news in order can calculate and obtain each mirror
As the distance between product locations to be chosen in selection region, the minimum T mirror image selection region of preferred distance sum is set
1 is set to, other mirror images selection region is set to 0, and than choosing region if any two or three mirror images, then chosen distance sum is minimum
A mirror image selection region R values be 1, other are 0；When there is four mirror images selection regions, then chosen distance sum is minimum
The R values in two mirror image selection regions are 1, and other are 0.
In the present embodiment, K1、K2、K3It is proportionality constant, with a default value.Influence in view of M is more than N, N shadow
Ring and be more than R, can be by K1、K2、K3It is respectively set to 2.5,1.5 and 1.
After the above method, the mirror image selection region finally chosen is most suitable region.If Order splitting value
Maximum mirror image selection region has multiple, then the number order for choosing region according to mirror image selects first mirror image selection region hair
Play picking task.The Y value that such as last calculating obtains mirror image selection region A, B is identical, then acquiescence selection mirror image selection region A.
Certainly occur and just start just filter out satisfactory mirror image selection region, i.e., each mirror image selection region
In have at least a kind of commodity stocks not enough, then selectSimultaneously initiate to pick in the maximum mirror image selection region of value
Goods task, i.e. quantity in stock meet the type of merchandize sum that selection is required.IfThe maximum mirror image selection area of value
Domain has multiple, then the number order for choosing region according to mirror image selects first mirror image selection region to initiate picking task.
Step S3, according to selection task during mirror image selection region selection, will if wherein there is commodity stocks not enough
The commodity connection Turnover Box chosen is transmitted to next mirror image by power transmission line in the lump chooses region, while commodity are poor
Specified number realizes that commodity relay is chosen according to sending to corresponding mirror image selection region.
During mirror image selection region selection, if the situation that commodity stocks is not enough, then all commodity of order are picked
After choosing, not enough differential section is sent to next mirror image and chooses region, and the commodity and Turnover Box of selection are passed through together
Power transmission line transmit to next mirror image choose region, next mirror image selection region selection personnel according to difference data after
Continuous selection, realizes that relay is chosen.
If step S4, all mirror images choose region after relay is chosen, still the shortage of stock, then generate passive replenish and appoint
Business, after the completion of replenishing, continues to choose until selection is finished.
After a circle relay, still there are commodity to choose quantity not enough, then trigger the passive task that replenishes, after the completion of replenishing, after
Continuous selection is until selection is finished.When replenishing, all mirror images selection region can synchronously be replenished.
In addition, when finding that certain part commodity reaches stock's lower limit in mirror image selection region, the task that actively replenishes can also be generated,
The principle that replenishes is to maintain each mirror image selection region commodity category and stockpile number is essentially identical.
