The customer demand information includes at least the following information:
the warehouse-in/out mode comprises two modes, which are respectively: a first-in first-out mode and a first-in last-out mode;
storage capacity: the unit is support, and the stock of all trays in the whole warehouse area can also be measured as the total support number.
Warehousing batch range: the unit is a stock/SKU, namely, the stock quantity range of each SKU required for one time is usually the same as that of the SKU in the same batch and occupies the same channel.
Site information: the unit can be m, and mainly comprises information of length a, width b, height c and the like of the planning site

If the length, the width and the height of the goods are the same, determining the length, the width and the height of the goods as the length, the width and the height of the storage position; if the length, width and height of the goods are not all the same, the longest length, the widest width and the highest height of the goods are taken as the length, width and height of the storage space.
And step 403, determining the number of shelf layers according to the height of the place in the place information, the height of the storage position and the safety requirement information.
The layer height of each layer is the sum of the storage height h and the safety requirement height h1 h + h 1.
The number of shelf layers is c/(h + h1), and c is the height of the field.
And step 404, determining the number of channels according to the length of the field and the width of the channel in the field information.
The number of channels T is the ratio of the length a of the field to the width T of the channel, i.e. T is a/T.
And step 405, determining the total depth number according to the width of the site and the width of the storage position in the site information.
The total depth number D is the ratio of the width b of the field to the width D of the depth, namely D equals to b/D.

In this step, according to the warehousing batch range, the depth number is determined with the divisor of the batch number (torr number) with the highest frequency and the next highest frequency, and the partitioning of the library area according to the determined depth number may be as follows:
if the warehousing lot size is in the range of 4-10, wherein the highest frequency is 5 torr, the second highest frequency is 8 torr, the divisor of 5 torr is 5, and the divisor of 8 torr is 4, it is recommended to set a 5-depth warehouse area and a 4-depth warehouse area.

in other words, under the mode, the two outermost sides of the field are single-depth shuttleless plate racks, and the depth of the storage area adjacent to the single-depth racks is as large as possible.
When the warehouse entry and exit mode is a first-in and last-out mode, determining the positions of the warehouse section deployments with different depths according to the warehouse entry and exit mode based on the balance of the stacker task allocation, wherein the steps comprise:
and the depth numbers of the reservoir areas arranged at the two sides of the field and the reservoir areas adjacent to the reservoir areas are determined minimum depth numbers.
That is, in this mode, the depth of the outermost side of the field and the reservoir area adjacent to the outermost reservoir area is as small as possible.
The sum of the depths for the other location areas in the two modes is as balanced as possible.
And 408, determining the number of the divided base areas as the number of the stackers, and determining the total number of the shuttle plates according to the number of the shuttle plates set for one stacker.

EXAMPLE III
It is verified whether the first number of storage bits determined in the first and second embodiments meets the storage requirement.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating a process of verifying the number of storage bits in the third embodiment of the present application. The method comprises the following specific steps:
To ensure that the goods in the same aisle are in the same batch as sku, and therefore more or less empty storage locations in a single aisle must be unoccupied, the reduced rate is the proportion of the storage locations for that portion.
Therefore, the value of rate is mainly related to warehousing batches and the frequency thereof, and if the most efficient utilization can be achieved when all batches are warehoused, namely 5 torr goods can be divided into a 5-depth channel instead of 2 4-depth channels, and 8 torr goods can be divided into two 4-depth channels instead of a 5-depth channel and a 4-depth channel.
The conversion ratio is calculated by the following equation:
wherein n represents the number of batch warehousing situations, such as one-time warehousing X Torr, and is regarded as a situation; p is a radical ofiIndicates the warehousing frequency corresponding to the ith batch condition, fiIndicates the number of empty storage positions, u, at the highest efficiency corresponding to the ith batch conditioniIndicating the total number of storage bits occupied by the ith batch condition.
If the number of the warehousing times is totally 100, the warehousing frequency corresponding to the situation of warehousing for one time at 4 torr is 30%, the warehousing frequency corresponding to the situation of warehousing for one time at 4 torr is 20%, and the warehousing frequency corresponding to the situation of warehousing for one time at 5 torr is 20%, and the warehousing frequency corresponding to the situation of warehousing for one time at 8 torr is 50%;
if the condition of one-time warehousing is 4 torr, warehousing is a channel with 4 depths, and the number of the corresponding empty storage bits under the highest utilization is 0; the total reserve position is 4;
in the condition of 5 torr in one warehouse, a 4-depth channel is put in the warehouse, and the number of corresponding empty storage positions under the highest utilization is 1; the total reserve position is 5.
The second number of storage positions is: a ratio of the storage amount to the conversion ratio.
The second number of bins thus calculated is the minimum of one bin number.
That is, the determined first storage quantity is smaller than the minimum storage quantity meeting the traffic demand, so that the first storage quantity cannot be deployed, and the customer demand needs to be acquired again to perform resource allocation again.
And 505, when it is determined that the first storage quantity is greater than the second storage quantity, adjusting the number of channels and/or the number of layers according to the interval range corresponding to the second storage quantity and the first storage quantity. The flow is ended.
I.e. the determined minimum number of memory bits, i.e. the second number of memory bits is smaller than the first number of memory bits, there is room for adjustment to reduce the number of channels, and/or the number of layers by reducing the number of memory bits, in order to reduce the cost.
When the first storage quantity is the same as the second storage quantity, that is, the requirement of the storage quantity can be met, and no adjustable space is available, the resource allocation can be directly performed on the first storage quantity.
In the embodiment, the number of layers and the bank areas of the dense warehousing system are divided according to the customer demand information, and the depth number of each bank area, the length, the width and the height of each storage position, the number of configured stackers, the number of configured shuttling plates and the like are optimally configured; according to the warehouse-in and warehouse-out mode in the customer demand information, reasonable distribution of warehouse areas with different depths under different modes is realized based on the task allocation balance of the stacker;
determining the minimum quantity of the reserve positions by calculating the conversion ratio of the task quantity finished by the stacker, comparing the minimum quantity of the reserve positions with the currently determined quantity of the reserve positions, and determining whether the current quantity of the reserve positions meets the requirement of the storage quantity or not and whether an adjustment space exists or not;
after the final storage position quantity is determined, resource allocation is carried out according to the determined parameters, and the resource allocation of the dense warehousing system can be realized at low cost.

Referring to fig. 6, fig. 6 is a schematic view illustrating a flow of verifying whether the number of stackers meets the flow of warehouse entry and exit in the embodiment of the present application. The method comprises the following specific steps:
The stacker in the embodiment of the application has the same working capacity with the stacker in the single-deep vertical warehouse, namely a carrying task, and the difference is that the stacker in the intensive warehousing system also comprises a shuttle plate channel-changing carrying task besides a cargo carrying task.
Based on this, the task amount completed by the stacker includes the task amount of the stacker for transporting the shuttle plate, the ex-warehouse task amount and the in-warehouse task amount.
The stacker efficiency algorithm used in calculating the task amount completed by the stacker in the embodiment of the present application may be FEM or the like, which is not limited in the embodiment of the present application, and the calculation is performed based on the device parameters of the stacker in the calculation.
And step 602, calculating the proportion of the channel changing task according to the depth number of the two corresponding reservoir areas of the stacker.
If the depth numbers of the left side and the right side of one stacker are both 4, the default is that each 5 tasks comprise a channel changing task, and the proportion of the channel changing tasks is 20%.
And 603, calculating the task quantity of the tunnel corresponding to the stacker according to the ratio of the task quantity finished by the stacker to the channel changing task.
The task amount of a tunnel corresponding to one stacker is as follows: y (1-z), wherein y is the task amount completed by the stacker, and z is the proportion of the stacker to change the channel task.
And step 604, calculating the sum of the task quantities of the lanes corresponding to all the stackers as the total task quantity.
The total task volume is calculated by:
wherein m is the number of stackers, yjFor the amount of tasks completed by the jth stacker, zjAnd changing the channel task proportion for the jth stacker.
The determined resource configuration information includes: the length, width and height of the storage positions, the number of channels, the number of layers, the depth, the number of divided base areas, the determined number of the pilers, the number of the shuttle plates and the like are output to a resource configuration platform to perform resource configuration, namely the construction of the intensive warehousing system.
The number of the default pilers is enough, so that the whole system can achieve the highest efficiency for ensuring that the tasks of the pilers are uninterrupted, the tasks between the pilers and the shuttle plates can be smoothly linked, and the task circulation of the pilers in a roadway and the task circulation of the shuttle plates in a channel need to be compared.
Generally, each roadway is provided with 1-2 shuttle plates to achieve the smooth connection degree.
If so, the number of the stackers currently set by the task is reasonable, the flow requirement of the client can be met, and the lowest cost can be realized.
And step 607, re-determining the number of the stackers.
That is, the currently determined parameters cannot meet the resource allocation requirements, and the relevant resource parameters need to be readjusted.
In the embodiment, the number of layers and the bank areas of the dense warehousing system are divided according to the customer demand information, and the depth number of each bank area, the length, the width and the height of each storage position, the number of configured stackers, the number of configured shuttling plates and the like are optimally configured; according to the warehouse-in and warehouse-out mode in the customer demand information, reasonable distribution of warehouse areas with different depths under different modes is realized based on the task allocation balance of the stacker;
verifying whether the total number of the currently determined stackers can meet the flow demand or not by calculating the total task amount actually completed by the stackers so as to determine the reasonable total number of the stackers;
after the final total number of the stackers is determined, resource allocation is carried out according to the determined parameters, and the resource allocation of the dense warehousing system can be realized at low cost.
