Further, in the comparison in step S2, when the received quantity is less than the reference quantity, the operation proceeds to step S5, and then it is determined whether or not there is a round shelf for the same type of product. If there are fractional shelves, products are sequentially stored from the fractional shelf having the largest number of stored products (step S6), and when the storage of all products is completed, the storage operation is finished (step S7).

On the other hand, if there is no fractional shelf of the same type of product, the operation proceeds to step S8 to determine whether or not there is an empty shelf. Then, when there is an empty shelf, an instruction to store the product stored in the empty shelf is output to the mobile terminal 4 (step S4). If there are no empty shelves, an instruction to store the products stored in the temporary storage area is output to the mobile terminal 4 (step S9).

The above is a series of processes for instructing the storage shelves, and this process will be specifically described using actual numerical values.

FIG. 5 shows an example of the current storage status of each shelf recorded in the management file 1.

That is, 50 products a with a reference quantity of 50 are stored in the shelf 51a, and the shelf 51a is a full shelf. Further, the shelf 51b is a product b with a standard quantity of 100.
80 shelves are stored, and this shelf 51b is full of 20
It is a fractional shelf that leaves room for individual pieces (a shelf that is less than full).

Further, 150 products c having a reference quantity of 150 are stored on the shelf 51c, and the shelf 51c is a full shelf. In addition, the shelf 51d stores 20 pieces of the product a having a reference quantity of 50, and the shelf 51d is a fractional shelf that leaves a margin of 30 until it is full.

The shelf 51e is an empty shelf. Further, 30 shelves of the standard quantity 50 of the product a are stored in the shelves 51f, and the shelves 51f are fractional shelves that leave a margin of 20 until full.

In such a storage situation, when a new product is stored in the storage warehouse 5, the worker inputs the type and quantity of the product from the portable terminal 4 and sends it to the warehouse management computer 2 ( Step S1).

Here, the data transmitted from the portable terminal 4 is (1) the data indicating the product a and the quantity of 50 (that is, the data indicating that the product a is fully loaded on the carriage 6). In the case, (2) the case where the data is the product a and the quantity 40 is described.

(1) In the case of data indicating the product a and the quantity of 50 pieces In this case, in the determination in step S2, the received quantity matches the reference quantity.
Proceed to and determine whether there are empty shelves. And in this case, since the shelf 51e is an empty shelf,
In the receiving shelf instruction unit 22, the stored product a is stored in the empty shelf 51.
The instruction to store in e is output to the mobile terminal 4 (step S4).

The instruction contents output from the storage shelf instruction unit 22 to the portable terminal 4 are also output to the result management unit 21 at the same time, and the result management unit 21 follows the instruction contents and stores the contents of the management file 1 in accordance with the instruction contents. Is sequentially rewritten. Therefore, the data recorded in the management file 1 at the time when the warehousing process is completed is the shelf 51e that was an empty shelf.
Is data indicating that a full shelf has been filled with 50 products a.

(2) In the case of data indicating the product a and the quantity of 40 pieces In this case, since the quantity received is not the same as the reference quantity in the judgment in step S2, the next step S
Proceeding to step 5, it is determined whether or not there are fractional shelves for products of the same type. Then, in this case, since the shelf 51d and the shelf 51f are fractional shelves of the product a, the receiving shelf instruction unit 22:
The standard quantity is full in the fractional shelf 51f with the largest number of storage 2
An instruction to store 0 products is output to the mobile terminal 4 (step S6). After that, it is determined whether or not the goods have been stored. In this case, since 20 (40 to 20) products still remain, the storage shelf instruction unit 22 stores the number of items stored at this point. Most number of fractional shelf 51d
An instruction to store the remaining 20 products is output to the mobile terminal 4 (step S6). After that, it is determined whether or not the warehousing is completed. Since all the products a stored at this time are stored in any of the shelves, the warehousing process is ended here.

The instruction contents output from the storage shelf instruction unit 22 to the portable terminal 4 are also output to the result management unit 21 at the same time, and the result management unit 21 follows the contents of the management file 1 according to the instruction contents. Is sequentially rewritten. Therefore, as for the data recorded in the management file 1 at the time when the warehousing process is completed, 50 shelves of the product 51 are stored in the shelf 51f and 40 of the product a are stored in the shelf 51d. Is data indicating.

That is, the number of fractional shelves in the storage warehouse 5 is reduced as much as possible by performing the above-described processing (that is, the processing of sequentially storing the fractional shelves with the largest number of storages) in the storage shelf instruction section 22. As a result, the efficiency of use of the shelf is improved.

Next, the case of designating the delivery shelf will be described with reference to the flowchart shown in FIG.

This data is received by the delivery shelf instruction unit 23 via the wireless transmission / reception modem 3.

Upon receipt of the data from the portable terminal 4, the delivery shelf instructing section 23 reads out the storage status data recorded in the management file 1 and compares the two data.

That is, the delivery shelf instruction unit 23 first compares the delivery quantity with the reference quantity of the product to be delivered (step S12). If the delivery quantity does not match the reference quantity, the operation proceeds to step S15. Proceed.

Further, in the judgment at step S12,
If the delivery quantity matches the reference quantity, then it is determined whether or not there is a full shelf for the product (step S13).
Then, if there is a full shelf, an instruction to leave the product from the full shelf is output to the mobile terminal 4. As a result, the worker carries out the product from the full shelf displayed on the mobile terminal 4.

On the other hand, when the delivery quantity is the reference quantity and there is no full shelf, steps S13 to S1.
The operation proceeds to 5.

In step S15, it is determined whether or not there are fractional shelves for products of the same type. When there are fractional shelves, the products are sequentially delivered from the fractional shelves with the smallest number of stored items (step S16), and when all the products have been delivered, the delivery operation ends (step S17).

On the other hand, in the judgment at step S15,
If there is no fractional shelf for the same type of product, step S1
The operation proceeds to step 8 to determine whether there is a full shelf of the product. Then, if there is a full shelf, an instruction to leave the product from the full shelf is output to the mobile terminal 4 (step S14). If there is no full shelf, information indicating that the stock is out of stock is output to the mobile terminal 4 (step S19).

The above is a series of processing for instructing the delivery shelf, and this processing will be specifically described using actual numerical values.

The current storage status of each shelf recorded in the management file 1 is the same as that shown in FIG.

In such a storage situation, the worker inputs the type and quantity of the product to be delivered from the portable terminal 4 and sends it to the warehouse management computer 2 (step S11).

Here, the data transmitted from the portable terminal 4 is (3) data indicating the product a and the quantity of 50 (that is, the data indicating that the product a is fully loaded on the carriage 6). In the case, (4) the case where the data is the product a and the quantity 40 will be described.

(3) In the case of data indicating product a and quantity of 50 In this case, since the quantity to be delivered coincides with the reference quantity in the determination in step S12, next step S1
Proceed to step 3 to determine whether there is a full shelf. And
In this case, since the shelves 51a are full shelves, the delivery shelf instruction unit 23 outputs an instruction to take out products from the full shelves 51a to the mobile terminal 4 (step S14).

The instruction content output from the delivery shelf instruction section 23 to the portable terminal 4 is also output to the result management section 21 at the same time, and the result management section 21 follows the content of the management file 1 according to the instruction content. Is sequentially rewritten. Therefore, the data recorded in the management file 1 at the time when the shipping process is completed is data indicating that the shelf 51a is newly an empty shelf.

(4) In the case of data indicating the product a and the quantity of 40 pieces In this case, since the quantity to be delivered does not match the reference quantity in the judgment in step S12, the next step S
Proceeding to step 15, it is determined whether or not there are fractional shelves for products of the same type. Then, in this case, since the shelf 51d and the shelf 51f are fractional shelves of the product a, the delivery shelf instruction unit 23
An instruction to issue 20 products to the fractional shelf 51d having the smallest number of stored items is output to the mobile terminal 4 (step S1).
6). After that, it is judged whether or not the delivery is completed, but in this case, 20 pieces (40 pieces-20
Since the number of products) remains as an undelivered product, the output shelf instruction unit 23 causes the fraction shelf 51f with the smallest storage number at this point.
Then, an instruction to leave the remaining 20 products is output to the mobile terminal 4 (step S16). After that, it is judged whether or not the shipping is completed. At this point, 40
Since all of the individual products a have been delivered, the delivery process ends here.

The instruction contents output from the delivery shelf instruction unit 23 to the portable terminal 4 are also output to the performance management unit 21 at the same time, and the performance management unit 21 follows the contents of the management file 1 in accordance with the content of the instructions. Is sequentially rewritten. Therefore, the data recorded in the management file 1 at the time of finishing the shipping process is that the shelf 51d is a new empty shelf and the shelf 51f is a fractional shelf for storing 10 products a. It is the data shown.

That is, by performing the above-described processing (that is, processing of sequentially issuing the fractional shelf having the smallest number of storages) in the delivery shelf instruction unit 23, the number of fractional shelves in the storage warehouse 5 is minimized. As a result, the efficiency of use of the shelf is improved.
