One embodiment of method for inventory control of the invention is described with reference to Fig. 3.
Fig. 3 is the flow chart of method for inventory control one embodiment of the present invention.As shown in figure 3, the method bag of the embodiment Include:
Step S302, it is determined that storage has the Turnover Box of more than one commodity in outbound list as the alternative Turnover Box of outbound.
Wherein, in outbound list outbound in need more than one commodity.
Step S304, the outbound distance according to the alternative Turnover Box of each outbound, the Turnover Box for treating outbound in each tunnel The type of merchandize number deposited in number and the alternative Turnover Box of each outbound, determines that the relation of outbound cost is represented.
Wherein, tunnel refers to two row's shelf of a shared shuttle, and shuttle is used to for Turnover Box to be transported to place layer Outbound cache bit, be carried to for Turnover Box on the transmission line of one layer of shelf by outbound elevator from outbound cache bit, and then has enough to meet the need Case reaches selection station by transmission line.Due to the limitation of shuttle transporting capacity, the week for treating outbound may be overstock on tunnel Turnning box, in order to improve the outbound efficiency of Turnover Box as far as possible, it should balance the number of the outbound Turnover Box between multiple tunnels as far as possible. Herein, the number of the Turnover Box for treating outbound in each tunnel can be the number of overstocked Turnover Box and will be chosen as out The number of the alternative Turnover Box of outbound of storehouse Turnover Box.
Preferably, the relation of outbound cost is represented and determined using following methods:By the outbound of the alternative Turnover Box of all outbounds Apart from sum as the first variable;The number of the Turnover Box of outbound lane at most minimum with the number of the Turnover Box for treating outbound will be treated The difference of the number of the Turnover Box for treating outbound in road is used as the second variable;The type of merchandize that will be deposited in the alternative Turnover Box of all outbounds Several sums reciprocal are used as ternary;According to the first variable, the second variable, ternary weight to the first variable, second Variable, ternary are weighted, and the relation for obtaining outbound cost is represented.The relation of specific outbound cost is represented can use public affairs Formula (1) is indicated:
Wherein, S represents the total number of the alternative Turnover Box of outbound, xi=1 expression alternative Turnover Box of i-th outbound is chosen as out Storehouse Turnover Box, xi=0 expression alternative Turnover Box of i-th outbound is not chosen as outbound Turnover Box, LiRepresent that i-th outbound is alternatively all The outbound distance of turnning box, the outbound distance for example, floor height of Turnover Box place storage space adds the institute of Turnover Box with the product of balance parameters In the horizontal range of storage space to outbound mouthful, balance parameters are obtained for test, the rising or falling speed for balancing outbound elevator, with biography Send the difference between the horizontal velocity of band, when shuttle can with cross-layer picking when, outbound distance also need on aforementioned base increase Plus, the weight of shuttle cross-layer picking.Qj-QkRepresent the difference of the Turnover Box for treating outbound of any two tunnel j and k, CiRepresent The species of commodity in the alternative Turnover Box of i-th outbound, α, β and γ are respectively the first variable, the second variable, the power of ternary Weight.By formula (1) as can be seen that the outbound of the alternative Turnover Box of outbound chosen treats the week of outbound apart from smaller between tunnel Turnning box quantity is more balanced, and type of merchandize more at most outbound cost is smaller in the alternative Turnover Box of outbound of selection.
Step S306, the relation according to outbound cost represents, is chosen at and meets traffic constraints condition and commodity amount constraint The alternative Turnover Box of outbound for causing outbound cost minimum in the case of condition carries out outbound as outbound Turnover Box.
The alternative Turnover Box of outbound of selection also needs to meet traffic constraints condition and commodity amount constraints.Wherein, flow Amount constraints is that the number of the alternative Turnover Box of outbound chosen is not less than the difference and not of maximum outbound quantity and slack variable More than maximum outbound quantity;Commodity amount constraints is the total amount of each commodity of storage in the alternative Turnover Box of outbound chosen The outbound amount of each commodity in outbound list is not more than respectively;Maximum outbound quantity is according to the vacant of every layer of outbound cache bit of shelf What quantity determined.Maximum outbound quantity can be tried to achieve according to below equation:
Wherein, formula (3) is the constraints of formula (2), and S represents the total number of the alternative Turnover Box of outbound, xi=1 represents The alternative Turnover Box of i-th outbound is chosen as outbound Turnover Box, xi=0 expression alternative Turnover Box of i-th outbound is not chosen as outbound Turnover Box, BnRepresent the set of the shelf alternative Turnover Box of n-th layer outbound, EnRepresent the vacant number of shelf n-th layer outbound cache bit Amount.Maximum outbound quantity is obtained according to formula (2) and (3), then can obtain traffic constraints condition, slack variable is according to test The parameter that result is obtained, for example, 0,1,2 etc. integers.
Preferably, calculate in the case where traffic constraints condition and commodity amount constraints is met cause formula (1) minimum go out The alternative Turnover Box in storehouse, can be using the method for loop iteration:
First, it is chosen at and the minimum alternative Turnover Box of outbound of outbound cost is caused in the case of meeting traffic constraints condition, For example, the quantity of the alternative Turnover Box of outbound is 10, it is 5 to be calculated maximum outbound quantity by formula (2) and (3), and flow is about Beam condition is 4≤flow≤5, is selected so that the minimum alternative Turnover Box of outbound of formula (1) i.e. outbound cost is A, B, C, D.
Then, judge whether the alternative Turnover Box of outbound chosen meets commodity amount constraints, gone if being unsatisfactory for Fall to meet pre-conditioned Turnover Box, using remaining Turnover Box as the alternative Turnover Box of outbound, for example, including 3 kinds in outbound list Commodity, are respectively necessary for 100,150,120, but this 3 kinds of commodity sums are respectively 200 in A, B, C, D, 250, 150, more than the commodity amount for needing outbound, then choose one from A, B, C, D and meet pre-conditioned Turnover Box and remove, Pre-conditioned to be, for example, type of merchandize minimum number, the total volume of commodities is minimum, and a certain commodity amount is minimum, a certain commodity number Amount exceedes threshold value, and outbound can be configured according to the actual requirements apart from farthest etc..Now, an outbound is removed alternatively all After turnning box, the quantity of the alternative Turnover Box of outbound is 9.
Repeat the above steps, until the alternative Turnover Box of outbound chosen meets commodity amount constraints, by going out for choosing The alternative Turnover Box in storehouse carries out outbound as outbound Turnover Box., it is necessary to redefine traffic constraints condition in repetitive process, due to going out The vacant quantity of banked cache position may change.If additionally, the quantity of commodity cannot in the alternative Turnover Box of outbound chosen The commodity amount that outbound is needed in outbound list is reached, then the remaining commodity amount without outbound is incorporated into outbound list next time In carry out outbound.
Above-described embodiment considers the outbound distance of Turnover Box, business in the ability and Turnover Box of the process task in tunnel The species number of product determines outbound cost, and the need for limitation further combined with storage outflow and outbound list outbound commodity number Amount, choosing the Turnover Box for causing outbound cost minimum carries out outbound, and the storage location residing for Turnover Box is weighed in all directions, and tunnel is removed In capacity power and outbound list commodity with commodity in Turnover Box matching on value volume and range of product, and then choose outbound efficiency highest Turnover Box, it is possible to increase the overall outbound efficiency of commodity.
The present invention also provides a kind of construction method of outbound list, and the scheme that can be combined in previous embodiment is performed.
The order that commodity covariance meets default related condition is combined as outbound list.
Preferably, the order chosen in preset time period is added in outbound order set, according to outbound order collection The correlation of the commodity in remaining order in commodity in order in conjunction and preset time period, in determining outbound order set Order and each remaining order correlation;Chosen from remaining order and the order correlation highest in outbound order set Order be added in outbound order set;Said process is repeated, until the order in outbound order set reaches default order The commodity in order in quantity or outbound order set reach default commodity amount, by the order combination in outbound order set It is outbound list.
The order tried one's best when building outbound list in selection one ripple time (preset time period), it is to avoid first treatment order occur and lean on Order afterwards causes some orders to be unable to outbound at the appointed time.Various commodity, two orders can be included in one order Between correlation can be determined according to the correlation of the commodity included in order, specifically refer to below equation:
Wherein, M is the commodity amount in the first order, and N is the commodity amount in the second order, pmnIt is business in the first order The correlation of product m and commodity n in the second order, the correlation of two kinds of commodity is, for example, within a certain period of time simultaneously comprising this two kinds The ratio of the total amount of the outbound list in the quantity and the certain hour of the outbound list of commodity, or, wrap simultaneously within a certain period of time The ratio of the total amount containing the order in two kinds of quantity of the order of commodity and the certain hour.The correlation of commodity is higher to be shown The probability of two kinds of commodity outbounds simultaneously is higher.One remaining order is surplus for example with this with the correlation of order in outbound order set Remaining order is indicated with the total and/or average value of the correlation of all orders in outbound order set.
Further, correlation commodity higher can be deposited with reference to the construction method of outbound list, in Turnover Box, is so entered During row commodity ex-warehouse, the quantity of outbound Turnover Box can be reduced, improve outbound efficiency.
Outbound Turnover Box is after by artificial or robotic pick's commodity, in addition it is also necessary to return to shelf, and the present invention is also provided A kind of time storehouse method of outbound Turnover Box, is described with reference to Fig. 4.
Fig. 4 is the flow chart of another embodiment of method for inventory control of the present invention.As shown in figure 4, the method for the embodiment Including:
Step S402, it is determined that treating the classification of the Turnover Box of Hui Ku and corresponding storage space subregion of classifying.
Wherein, the classification of Turnover Box can be determined according to the classification of the commodity wherein deposited, and the classification of commodity can be with It is determined according to outbound rate or popular degree, if the classification that various commodity and commodity are deposited in a Turnover Box is different, The classification of the ratio-dependent Turnover Box shared by the commodity according to various classification, for example, A class commodity account for more than 50%, then by this week Turnning box is defined as A classes.The Turnover Box of same classification is stored in same storage space subregion.
Step S404, backlog amount and vacant storage space quantity according to each tunnel in storage space subregion choose Hui Ku lanes Road.
Wherein, it is preferential to choose the tunnel that backlog amount is few and vacant storage space quantity meets the turnover box number for treating Hui Ku and make It is Hui Ku tunnels.Preferably, the backlog amount in tunnel can be divided into different degree and corresponds to the first different power respectively Weight, and more big corresponding first weight of backlog amount is smaller, and the hollow remaining storage space quantity in tunnel is divided into different grades The second different weights are corresponded to respectively, and more big corresponding second weight of vacant storage space quantity is bigger, by the first weight and second Weight is added, and chooses the first weight with the second weight sum highest tunnel as Hui Ku tunnels.
Step S406, from corresponding each storage space in Hui Ku tunnels, selection outbound distance goes out with the Turnover Box for treating Hui Ku The storage space that storehouse rate matches returns storehouse storage space as the Turnover Box for treating Hui Ku, wherein, treat that the outbound rate of the Turnover Box of Hui Ku is bigger The outbound distance of the storage space of selection is nearer.
Preferably, by corresponding each storage space in Hui Ku tunnels according to outbound distance by as far as being closely ranked up;Choose sequence The outbound rate P that position is equal to the Turnover Box for treating Hui Ku is multiplied by the numerical value that Hui Ku tunnels correspondence storage space sum V is rounded downwardsStorage space as the Turnover Box for treating Hui Ku return storehouse storage space.Wherein, the outbound rate of Turnover Box is for example, wherein deposited Put the weighted average of the outbound rate of commodity.
Above-described embodiment carries out back stock and puts according to the classification of Turnover Box and outbound rate, the week that outbound rate can be made higher Turnning box storage outbound storage space closer to the distance, improves back storehouse efficiency, while being easy to next outbound, improves outbound efficiency.With reference to The outbound scheme of Turnover Box in previous embodiment, by continuous outbound and the adjustment of time storehouse process, the turnover in whole warehouse Case can all deposit in more rational position so that the overall outbound in warehouse and time storehouse efficiency obtain overall lifting.
New commodity restocking needs to choose suitable Turnover Box and is stored, and is referred to as put in storage, and the present invention also provides one kind and enters Storehouse method, is described with reference to Fig. 5.
Fig. 5 is the flow chart of another embodiment of method for inventory control of the present invention.As shown in figure 5, the method for the embodiment Including:
Step S502, it is determined that identical with the classification of commodity to be put in storage and deposit the minimum turnover of commodity amount to be put in storage Case is used as the alternative Turnover Box of storage.
Choosing the Turnover Box of commodity storage minimum number can make commodity storage try one's best dispersion so that excellent during outbound matching Change space bigger.
Step S504, chooses and is put in storage alternative Turnover Box as business to be put in storage with the correlation highest of commodity to be put in storage The storage Turnover Box of product.
The storage Turnover Box of commodity k to be put in storage can be represented by below equation:
Wherein, H is the set for being put in storage alternative Turnover Box, and i represents the numbering for being put in storage alternative Turnover Box, SiRepresent i-th The species number of commodity, p in the alternative Turnover Box in storehousejkCommodity j is with commodity k's to be put in storage in representing i-th alternative Turnover Box of storage Correlation.
Vacant outbound cache bit is also needed to additionally, being put in storage alternative Turnover Box and being currently located layer, in addition it is also necessary to the Turnover Box Middle commodity are no more than maximum size.Further, select wait can be implemented according to Fig. 4 after the storage Turnover Box of the commodity be put in storage Method in example carries out performing step S402~S406 after Hui Ku, i.e. step S504 to the storage Turnover Box.Further, by May simultaneously carried out in outbound storage, priority can also determined according to the task busy extent of outbound and storage, if entered Storehouse is preferential high in outbound priority, then the storage Turnover Box of the commodity be put in storage can not be matched by outbound and positioned again, if outbound It is preferential high in storage priority, then can just not be chosen as storage Turnover Box as outbound Turnover Box.
