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
