Working condition cost is big when being carrying state than the alternative shelf when the alternative shelf are in storehouse state.The work of alternative shelf
State cost can be configured according to the actual requirements, for example, working condition cost is 1 when alternative shelf are in storehouse state,
When alternative shelf are carrying state, working condition cost is 0.
2) by the distance of each alternative shelf to outbound work station and each alternative carrier to corresponding alternative shelf
The second outbound cost is used as apart from sum.
For example, defining cijFor carrier i to shelf j distance, the distance is carrier i to shelf j beeline.It is fixed
Adopted cjkFor shelf j to outbound work station k distance, the distance is shelf j to outbound work station k beeline.For restocking
Shelf in carrying can set cij=0

The quantity for the treating outbound commodity limit deposited in the limitation of the traffic constraints condition such as free buffer bit quantity of work station or warehouse
System, causes the outbound that can not complete to need outbound commodity during an outbound, therefore, the selection that should try one's best disclosure satisfy that
The shelf and carrier of outbound demand are to outbound work station, so as to set the 3rd outbound cost.When treat outbound commodity do not complete
Amount is bigger, and outbound cost may be bigger caused by representing the shelf and carrier chosen.
4) according to the first weight, the second weight and the 3rd weight respectively to the first outbound cost, the second outbound cost
Summation is weighted with the 3rd outbound cost item obtains the relation of outbound cost represent.
Step S306, is represented according to the relation of outbound cost, and being chosen in the case of meeting traffic constraints condition makes to draw
The alternative shelf of storehouse cost minimization and alternative carrier corresponding with alternative shelf, as outbound shelf and with outbound shelf pair
The outbound carrier answered.
Traffic constraints condition includes the corresponding alternative shelf of an outbound work station outbound no more than the outbound work station
Free buffer bit quantity, or traffic constraints condition go out including the corresponding alternative shelf of an outbound work station outbound no more than this
The free buffer bit quantity of storehouse work station, and keep for the quantity of the carrier of storage to reach predetermined number.
Keeping for the predetermined number of the carrier of storage can be determined using following methods：
The sum that reserved ratio obtains keeping for the carrier of storage is multiplied by using carrier sum；
Go to be put in storage the carrier quantity of work station using keeping for the carrier sum of storage to subtract, subtract and do not include
The quantity of any shelf returned from storage work station for treating outbound commodity, obtains keeping for the present count of the carrier of storage
Amount.
For example, the quantity for remembering all carriers is N, it is r to reserve ratio, keeps for the total N of the carrier of storagea=
r·N；The current carrier quantity for going to be put in storage work station of note is Nb, then the carrier number N for being used to be put in storage that should also retainc
=max (Na-Nb-Nf, 0), wherein NfRepresent not including any one shelf returned from storage work station for treating outbound commodity.Nb
The quantity of the carrier of storage work is done in expression.For treating being returned from storage work station for outbound commodity comprising any one
Shelf can be preferentially chosen for outbound shelf, will not be preserved for storage, therefore, NfExpression is treated out not comprising any one
The shelf returned from storage work station of storehouse commodity.
Alternative carrier includes idle alternative carrier and carries the alternative carrier of alternative shelf, preferentially from institute
State idle alternative carrier and choose the carrier for keeping for storage.That is,
It should be preserved for the car number N of storage in idle alternative carrierd=min (| Ia|,Nc)；
Further, it is preserved for the car number of storage from the carrier returned from storage work station, from storage
It should be preserved for the car number N of storage in the carrier that work station is returnede=min (Nc-Nd,|Ib|)。
