Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inventory of merchandise, such as plants, animals, fish, etc., in which the nature of the organism itself is a commodity or a commodity derived from the organism, and therefore its properties change from moment to moment. The present invention relates to a computer system for optimizing the arrangement of merchandise in a storage warehouse.

In particular, the present invention relates to a computer system capable of appropriately managing the arrangement in a warehouse for a product such as a banana that requires aging processing during storage.

[0003]

2. Description of the Related Art As a general rule, ordinary industrial products do not change their properties with the passage of time. With respect to the storage of products, in principle, no special conditions regarding the temperature and the like are necessary, so it is only necessary to secure a storage warehouse with a relatively large space and store each product clearly.

However, in the case where the organism itself is a product such as a plant, an animal, or a fish, or a product called a fresh food of biological origin such as vegetables, fruits, flowers, and meat, or a product such as a flower, comparison is made. The process of aging and rotting progresses in a very short period of time, the characteristics of the product change from moment to moment, and the product value also changes accordingly. Therefore, a warehouse that stores such products needs to be able to create and maintain a special environment by operating temperature conditions, etc., and it is possible to secure a relatively large space from the viewpoint of construction costs and running costs. difficult. In other words, it becomes necessary to use the relatively narrow space efficiently to store the products.

However, when many products are stored in a small space, a plurality of products whose property changes at various stages are likely to be mixed in one warehouse, making it difficult to know where and what is stored. . Further, while there are storage positions where products can be easily taken out, there are storage positions where other products are difficult to take out because they interfere with other products. Moreover, since the properties of each product change from moment to moment, even products that should be shipped or shipped immediately as a result of the changes in properties may be left unrecognized because they are stored in unclear locations. Or, since it is stored in a position where it is difficult to take out, it may have to be left for convenience of warehouse management work, and in either case, the product may be discarded.

[0006] Furthermore, in order to store and store the goods and arrange the arrangement, the door of the warehouse must be opened, but from the viewpoint of the quality of the goods, the storage condition such as temperature should be kept as small as possible without opening the door of the warehouse. It is desirable to keep it constant. That is, it is desirable to reduce the number of times of opening and closing. Usually, in a warehouse for such products, the inside is divided into a plurality of rooms, and it is designed so that even if the door of one room is opened, the doors of other rooms can be kept closed. Needless to say, it is better to open and close the door for each room as much as possible.

As for the method of arranging the products in the warehouse for the products that cause such a property change, it is the fact that the person in charge has to rely on the experience, and a more accurate layout management system has been demanded.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to propose a placement management system that enables computer-based placement management of products in a warehouse with respect to products whose properties change.

[0009]

A computer system for deciding the arrangement of a commodity inventory in a warehouse with a property change, the inventory table specifying the contents of the commodity inventory and the storage location of the commodity inventory in the warehouse. And 1 based on the inventory table and predetermined movement rules
Alternatively, a movement candidate specifying unit that specifies two or more movement candidates, a movement candidate display unit that displays the specified movement candidates together with a priority order based on the movement rule, and an actual storage location among the movement candidates. This is a management system for arranging in a warehouse, which has work result input means for receiving input of data on the moved inventory and rewriting means for updating the inventory table using the input data.

With this configuration, it becomes possible to properly arrange the products in the warehouse, which are accompanied by changes in properties, to effectively use the space in the warehouse and to reduce the discard rate and the out-of-stock rate of the products. it can.

Further, when the movement candidate specifying means specifies the movement candidate, it is possible to obtain the quantity data of the inventory for each property change state and the storage location from the inventory table and specify the movement candidate based on the quantity data. desirable. With this configuration, it becomes possible to easily change the arrangement of the products according to the changing state of the property.

[0012] It is also preferable that the movement rule is set to collect the inventory whose property changes are similar to one or at most two storage locations. With this configuration, since it is possible to collect and manage products with property changes for each condition of the property, it becomes easier to set storage conditions and the like, and more reliable management becomes possible.

Further, it has an inventory display means for displaying the contents of the stock at each storage location on the screen by using the stock table, and in displaying the contents of the stock, the change status of the property of each stock is classified by color. It is desirable to display it. With this configuration, it is possible to intuitively understand where and how the property in the warehouse is in a changed state, and thus it is possible to immediately determine the validity of the movement candidate presented by the system.

In addition, when any one of the movement candidates displayed by the movement candidate display means is selected to move the storage location, a simulation of the placement in the warehouse is performed and the result of the simulation is displayed. It is desirable to have confirmation means. With this configuration, the situation when the movement candidate presented by the system is temporarily adopted can be confirmed on the screen, so that more efficient movement work can be performed.

Here, it is preferable that the movement candidate specifying means newly specifies one or two or more movement candidates based on the simulation result and the movement rule, and the movement candidate display means displays the new movement candidate. . With this configuration,
If you make one move that the system suggests,
It is possible to understand in advance what kind of influence it will have.

Further, it is desirable that the property is rewritten at any time based on a rewriting rule predetermined so as to correspond to the actual property change of the product. With this configuration, it becomes possible to move a product with property changes within the warehouse while always reflecting a correct property change state even after a lapse of a certain time.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, one embodiment of a system of the present invention will be described with reference to the drawings regarding arrangement management in a warehouse for storing bananas, which is an example of a product whose properties change.

Commodities such as bananas and kiwifruit are harvested in the immature and hard state in the farms of the producing countries, packed in cartons, and shipped to Japan in large quantities by ship. After that, in Japan, it is stored and aged for several days in a warehouse where environmental conditions such as temperature, atmospheric pressure and ethylene gas concentration are adjusted.
The warehouse used for storage here is composed of a plurality of rooms that are separated from each other, and each room stores a carton that stores products in pallet units, and one room can store a large number of pallets. . This situation is shown in FIG. FIG. 1A is a front external view of a warehouse, where the warehouse is
It is divided into 5 rooms, named E and marked on the door. Each room can be sealed with a door 1, and the environmental conditions in each room are appropriately adjusted so as to be optimal for the condition of the stored products and the shipping plan. The interior of one room is shown in FIGS. 1 (b) and 1 (c).
(B) is a front view showing a state where a door of one room is opened, and (c) is a view showing a cross section taken along line XX 'of (b). The interior of the room is a two-story building consisting of a second-floor part 2 and a first-floor part 3. On each floor, there are two rows horizontally facing the front of the warehouse, and pallets 5 from the door side to the back of the room.
Can store 3 rows. In other words, one room has 2 rows x 3 rows x 2
Tier = 12 pallets can be stored, and each pallet can be stacked 3 rows x 3 rows x 3 tiers = 27 tiers = 27 pallets, so each room can store up to 324 cartons. be able to. In addition, 32 for the entire warehouse
4 cartons x 5 rooms = 1640 cartons can be stored.

The products stored in one room differ in the degree of aging even under the same environmental conditions due to the difference in the production area and variety, and initially, the products in the same maturity state (property) are Even if it is stored in the room, the state becomes disjointed over time, which makes management difficult and it becomes difficult to set appropriate environmental conditions.

Further, when the products are matured to some extent, they are sequentially shipped in carton units, so that the space in the room becomes gradually smaller. Since it is not desirable to leave this space open, it will be filled with products from other rooms or newly received products. If this is done properly without management, the maturity of the products in one room will also fall apart, making it difficult to understand the status of the products and making it impossible to set appropriate environmental conditions. Further, since one room is designed to have a relatively deep depth, in order to take out a product arranged in the back, it is necessary to once take out a product arranged in the front.

As an example of the present invention, FIG. 2 is a schematic block diagram of a system configured to manage banana inventory in the warehouse described above. The inventory information 21 in the storage unit 20 stores an inventory table that stores information about in-stock products.
An example thereof is shown in FIG. In the inventory table, the stock number attached to each shipment from the ship to the warehouse, the arrival date of the product from the ship to the warehouse, the sub-number for reflecting the change status after the shipment, the product type / production area / Product type number for specifying grade / size, standard for defining the processing state of the product, number of cartons in stock, maturity of the product, storage condition number for identifying environmental conditions in the warehouse room, inside the warehouse Each data of the storage position in is stored. Arrival date, arrival number,
The product type number is attached when the product arrives at the warehouse and is not changed thereafter. Standard, number, maturity, storage condition number,
The storage position is once input at the time of receipt, and is rewritten at any time according to changes in the situation thereafter.

The sub number is used when a product having the same arrival number and the same product type number is stored in two or more rooms.
It is attached to distinguish the goods in each room and to track the history of each. In other words, it is necessary for products that could not be grouped together at the receiving stage to be practically divided into two or more products with different maturity because the environmental conditions differ because they are stored in different rooms. Become. Therefore, if only moving within one room, the sub-number will not be newly added because of the same environmental conditions. The sub-number is
Two digit numbers from 01 to 99 are used in sequence. Sub-numbering can be done by moving some of the products with the same delivery number and the same product type number to another room and inputting that fact, or when the products have the same delivery number and the same product number.
It is performed when the above is input when the items are stored separately in the above-mentioned rooms or when the standard is changed by processing a part of the product. When the sub number is newly used, the sub numbers are sequentially added from 01, and when the sub numbers are already used, 1 is automatically added to the smallest sub number among the used sub numbers.

The product type number in the table of FIG. 3 is a code number for specifying the type, place of origin, grade, size, etc. of the product, and for specifying the reference change speed of the color index used as the maturity of the banana. is there. Each product type number is defined in the product type table stored in the product type information 22 of the storage unit 20. An example of the product type table is shown in FIG. The table of FIG. 4 will be described later.

The standard in the table of FIG. 3 is a code for distinguishing whether the product is as received or is undergoing some processing after the arrival. For bananas, it is for distinguishing the state in which the bunch at the time of arrival is cut and processed into units of 5 or 1 unit, the state of being placed on a tray or wrapped, or the state of work in process, It is used to distinguish products when they are stored in the room again after undergoing some processing.

The maturity level in the table of FIG. 3 is a numerical value indicating the current state of property change of each product, and as the index characterizing the property of bananas, the color of banana is usually used as described above. The index is used as maturity. By the way, as a way of determining the color index, it is uniformly set to 1.0 when it is imported and just rushed into the warehouse, and 5.0 when it is ripe to some extent and becomes a beautiful yellow color. The reference change value of the color index that differs for each product type is stored in the product type table of FIG.

The storage condition number in the table of FIG. 3 is
It is a number for specifying the environmental condition for storing the product.
The rate of change of banana color depends not only on the variety of banana and the country of production, but also on the environmental conditions in the room when the banana is stored. During storage, temperature, ethylene gas concentration and pressure in the room, and treatment time are important conditions, and various environmental conditions exist due to these differences. By changing the environmental conditions, it is possible to adjust the change speed of the banana properties, that is, the change speed of the color, to increase or decrease the color change time to adjust the time until a certain color is reached. The difference in the changing speed of the color index when the environmental conditions are different is evaluated based on the numerical value stored in the correction table shown in FIG. 5 as the correction rate of the reference changing speed of the color index for each storage condition number. For example, when the storage condition number of the environmental condition is "111", the correction rate becomes 0.7, and the reference change speed is multiplied by this "0.7" to obtain the actual change speed, and the maturity data is obtained. Rewrite. The table of FIG. 5 is included in the correction information 23 of the storage unit 20.

The storage position on the table of FIG. 3 represents the storage position of 12 pallets in each room and 60 pallets in the entire warehouse, and is represented by a 4-digit code number. It is expressed as. The first digit "A" is room A
Next, "upper" means the second floor, "right" means the right side toward the entrance of the room, and "middle" is the second from the front to the back, that is, the middle position in the depth direction. Means Therefore, “A upper right middle” indicates the second position from the front on the right side of the second floor of the room A.

The product type information 22 of the storage unit 20 stores a product type table for specifying the product type, an example of which is shown in FIG. In this table, corresponding to the product type code, the product type name, product origin, product quality grade,
Each data of the product size and the reference change value of the color index is stored. The reference change value of the color index means how much the color index changes for one day under the standard environmental conditions for the product of the specific product type code. In other words, using the reference change value data stored in FIG.
The color index of the 3456 products at a certain time point is, for example, 2.4.
Then, the color index after one day under the standard environmental condition is calculated as 2.4 + 1.1 × 1 day = 3.5. Therefore, this reference change value is a unique value for each product type.

The correction information 23 of the storage unit 20 stores the data of the correction rate for the reference change value of the color index for each storage condition number. The meaning of this data has already been explained.

Next, the processing unit 10 of this system will be described. The movement candidate specifying unit 11 of the processing unit 10 moves one of the stocks in the warehouse to another position in the same room or to another room based on the stock table of FIG. One or more movement candidates that are determined to be good are identified. The processing in the movement candidate identifying unit 11 is performed when there is a shipment from the warehouse and when there is a shipment to the warehouse, and movement between rooms moving to different rooms and adjustment of the storage position in the same room There is moving within the room.

First, the flow for selecting movement candidates for movement between rooms will be described with reference to the flowchart of FIG. When the room movement candidate display button on the display screen of the system is clicked, the process starts, and the inventory table constitutes a table of the number of stocked products for each room and maturity level (S2). An example of the number table is shown in FIG. In the table of FIG. 7, the horizontal axis uses the color index that is the degree of maturity, and the vertical axis shows the names of the rooms. The table stores the number of cartons of products having the respective color indexes stored in the respective rooms.

Next, for each column of the table of FIG. 7, the number of rows whose number is not 0 is obtained (S2). The result is shown in FIG. One of the purposes of the present system is to eliminate the situation where the products of the same maturity are stored in different rooms separately, so that the table of FIG. This is for grasping the storage position of the stored product. At that time, since it is necessary to take a prompt action for a product having a high maturity level, the products having a high maturity level are processed in order.

Therefore, in the table of FIG. 8, the number of rows is examined in order from the column with the highest maturity level of "6.9-6.0", and the "number of rows where the carton number is not 0" becomes 2 or more. Select the first column that has In the table of FIG. 8, the number of rows in the column of maturity “5.9-5.0” is “2”, and the maturity value of this column is first selected (S3). Next, returning to the table of FIG. 7, the row having the largest number of cartons in the columns having the same maturity value is searched (S4). In the table example of FIG. 7, the row of A has 82, which is the largest number.
One of the transfer candidates is determined so as to collect the product inventory of 5.9-5.0 (S5).

That is, if the products of the same maturity level are distributed in a plurality of rooms, they are moved to the room having the largest number of products of the maturity level so as to eliminate the distribution of the products. Make up. In this case, the 41 cartons of the product with the maturity level “5.9-5.0” stored in the room D are candidates for movement, and a message indicating that the commodity should be moved to the room A is displayed.

Then, it is judged whether or not there is a next column which is not yet a processing target in the table of FIG. 8 (S6).
If there is a column, the flow branches from S7 to the right and moves to the next column. In the above example, the maturity level of the table in FIG.
Since the process has been performed for the column of "9-5.0", the columns of the subsequent maturity levels "4.9-4.0" are unprocessed, and the process returns to the step S3 to continue the process of the next column of "4.9-4.0" or later. When the process is completed for all the columns and the next column in the table of FIG. 8 disappears, the flow branches downward from S6 to terminate the process of selecting the movement candidates regarding room movement (S).
7).

In this example, movement candidates are selected for all columns, but it is rare that products with a maturity degree of less than 3.0 are shipped, and they are collectively stored after they have arrived at the warehouse. In many cases, the selection of movement candidates may be limited to only products having a maturity of 3.0 or higher.
In this case, when the processing is completed up to the column with the maturity level of “3.9-3.0”, the movement candidate selection processing between the rooms is ended.

Next, a flow of selecting a movement candidate in the same room and displaying the movement candidate will be described. The processing flow of the movement candidate selection processing of the movement in the room starts when the room movement candidate selection button on the display screen of the system is clicked. This button is clicked when a new item arrives and it is necessary to sort out the warehouse, or when it is necessary to sort out the warehouse after the item is shipped, or a candidate for moving between rooms. This is, for example, when it is desired to know in advance what kind of movement in the room is required after moving.

A room A is selected as a typical example, and a flow of selecting room movement candidates will be described. After constructing the inventory table shown in FIG. 3 or a temporary inventory table that reflects movement of inter-room movement candidates in the inventory table, the storage position in room A of products of each maturity level is in front of the room. A number table indicating which of the positions from the inside to the inside is stored. An example of this table is shown in FIG. In this figure, "in front of A **" means that the position in front of the room in the depth direction includes both up, down, left and right.

Next, the column of the product with the highest maturity level in the table of FIG. 9, that is, the column of the products belonging to "6.9-6.0" is selected, and the number of stored items at the positions such as "A ** before" in that column is selected. It is determined that the difference from the maximum storage number of 1 is 1 or more, that is, whether there is a vacancy. If there is a vacancy, a product stored in "A ** medium" is searched from the inventory table or the temporary inventory table and is set as a movement candidate. If there is no product stored in "A ** medium", the product after "A **" is set as a movement candidate. Since the maximum number of cartons that can be stored "before A **" is 108, the movement candidates are determined when the number of cartons scheduled to move to "before A **" reaches 108. Next, it is judged whether or not there is a space in "A ** medium", and if there is a space, the products stored in "after A **" will be "A **".
* Movement candidates are set to move to “medium”. In this way, the movement candidates are determined in a pool manner. Further, the same operation is repeated in the descending order of maturity for a row in which a product having a lower maturity is stored, and movement candidates are determined. Explaining with the example in FIG. 9, first, “4 cartons” in the column of maturity level “6.9-6.0” are the movement candidates. Next, "82 cartons" in the row of "5.9-5.0" are candidates for movement to "A ** before", followed by "26 cartons" in the row of "4.9-4.0".
It becomes a move candidate to "A ** before". At this time, the last 26
Of the cartons, only 108-82-5 = 21 cartons are candidates for movement to "A ** before", and the remaining 5 cartons are candidates for movement to "A ** medium".

By doing so, it is possible to determine movement candidates so that a product with a higher degree of maturity is rearranged in a portion closer to the door. This is performed for each room as necessary, and movement candidates for movement within the room are determined.

When determining the moving candidates, the number of free spaces at the moving destination is compared with the number of moving candidates, and if the number of moving candidates is smaller than the number of free spaces at the moving destination, it is displayed as a moving candidate, or the moving candidate is displayed. If the number of items is larger than the number of free spaces at the destination, the order of displaying may be lowered. By doing so, although it is against effective use of the space in the warehouse, it is possible to reduce the amount of work required to actually move the product.

Next, the inventory display unit 12 of the processing unit 10 of the system
Will be described. The inventory display unit uses the inventory table of FIG. 3 or the temporary inventory table described above to configure and display a screen showing the inventory arrangement situation in the warehouse. An example of the screen is shown in FIG. The upper half portion of the screen 100 of FIG. 10 is the inventory layout diagram 110 configured by the inventory display unit. The inventory layout diagram is divided into 5 in the horizontal direction of the screen according to the number of rooms, and is divided into 2 in the vertical direction of the screen corresponding to the first floor and the second floor so that the whole is divided into 10. One large cell surrounded by a solid line represents each floor of each room, and each large cell is divided by the broken line into two in the horizontal direction and three in the vertical direction. That is, one cell is divided into six, and the small cell 120 which is the minimum unit corresponds to one pallet. The position of each pallet corresponding to each small cell is shown in FIG.
As shown in, "A" corresponds to the actual placement in the warehouse.
"B""C""D""E""up""down""right""left"
Each arrangement of "front", "middle", and "back" is defined.

In the display of one small cell, the color index, which is the maturity of the product stored in the corresponding pallet, is displayed in color (color is not displayed in the drawing of FIG. 10).
That is, a small cell is displayed in blue for a product with a color index of 1.0 immediately after arrival, and a small cell is displayed in yellow for a product with a color index of 5.0 that has been ripe to some extent and is beautiful yellow. It The other color indexes are also displayed in the colors corresponding to the respective numbers by the color table prepared in advance. When products of different color indexes are mixed in one pallet, the small cells are divided and the colors of the respective color indexes are displayed in the divided portions. This makes it possible for the person in charge of looking at the screen to intuitively understand what kind of color index product is stored in the warehouse, and whether the movement candidate proposed by the system is valid or not. Also, it becomes possible to intuitively determine which of the movement candidates should be adopted in which order.

Next, the movement candidate display section 13 of the processing section 10 will be described. The movement candidate display unit displays the movement candidates specified by the movement candidate specifying unit on the screen in a prepared format. The example is shown in the lower half of the screen example of FIG. Here, movement candidates for movement between rooms are displayed.

In the display of the movement candidates, among the movement candidates, the order in which the color index of the product is the largest, the color index, the current storage position specified as the movement candidate, the current number of cartons, and the movement destination are displayed. The storage position and the number of movements are displayed, and a check box for selecting whether or not to select the movement candidate is provided.

The movement candidates are displayed in descending order of rank. Further, the color index is displayed in a color specified from the color table, and the color corresponds to the display of the arrangement status of the above-mentioned stocked products. Furthermore, products stored in different storage positions are
If there are multiple candidates for movement, all of them are displayed at the current storage position. The destination storage position is selected such that it is placed in the closest space to the door among the destination room and the empty space in the destination room. As the number of pieces to be moved, the number that can be moved is displayed within a range that does not exceed the maximum number of the storage positions at the destination. When there is not enough empty space at the destination and it is necessary to divide and move the products managed under the same arrival number and weekly product type number, the sub numbers are used for distinction as described above. When the check box for selection on the screen is checked, it means that the display content of the line is the target of the work started by each button provided at the bottom of the screen.

When the intra-room movement button provided at the bottom of the screen in FIG. 10 is clicked, the movement candidate display section 13 displays the data of pre-selected inter-room movement candidates and the data read from the inventory table. , The movement candidates for the movement in the room included in the destination storage position are displayed. As a result, it is possible to know in advance what kind of room movement will occur at the destination. When the intra-room movement button is clicked without selecting the inter-room movement candidate, the intra-room movement candidate of the selected room is selected and displayed according to the above-mentioned flow via the screen for selecting which room. As a result, it is possible to understand what kind of movement is required at the present time in one room.

The simulation unit 14 of the processing unit 10 preliminarily grasps how the storage condition in the warehouse will change if any of the movement candidates is moved before the actual movement. Simulation is performed and the result is displayed. When the simulation button on the screen of FIG. 10 is clicked, the temporary inventory table is temporarily combined with the data of the room movement candidates selected by checking the check boxes in advance and the data read from the inventory table. And the simulation is performed. Based on the temporary table, the inventory display unit 12 displays the temporary arrangement status of the products, that is, the simulation result. The result is displayed in the inventory product arrangement status screen of the screen of FIG. This makes it possible to intuitively grasp in advance how the arrangement situation in the warehouse will change when a movement candidate is selected.

As a result of the simulation, it is decided which movement candidate is to be selected, the check box is checked, and the process output button at the bottom of the screen in FIG. 10 is clicked. After the room-to-room movement candidates that have been set, a process table displaying the movement destination inside-room movement candidates is printed out from the printer connected to the system. As a result, the worker in charge of rearranging the inventory in the warehouse can certainly know what kind of work should be performed.

The work result input unit 15 of the processing unit 10 receives an input for reflecting the arrangement status of the stock in the warehouse in the stock table after the actual moving work is completed. When the rewriting input button provided at the bottom of the screen in FIG. 10 is clicked after the moving product is selected, the rewriting unit 16 of the processing unit 10 is clicked.
Rewrites the inventory table according to the contents of the selected row.

The color index rewriting unit of the processing unit 17 automatically rewrites the color index of the stocked product on the stock table at 7:00 am before the start of the physical distribution work on one day. This process automatically rewrites the color index on the inventory table according to the rules that are set in advance for each product type in response to the actual property change status of the product. The purpose is to manage easily and surely.

The flow of this rewriting process will be described with reference to the flowchart of FIG. First, when the process starts
(SK10), the flow branches from SK20 to the right and enters the waiting state until the rewrite time is reached. At the preset rewriting time, the flow branches downward from SK20, selects the first row in the inventory table, and reads the product type number, maturity (color index), and storage condition number (SK30). The reference change value of the color index stored corresponding to the product type code is read from the product type table (SK40). Further, the correction rate corresponding to the previously read storage condition number is read from the correction table (SK50). Next, the previously read reference change value is multiplied by the correction rate that was also read previously, and this is added to the previously read color index to obtain a new color index (SK60). This new color index is overwritten and overwritten on the one-line color index selected at the beginning of the inventory table (SK70). Next, it judges whether there is a row next to the previously selected row (SK80), and if there is a next row, the flow branches right from SK80 to SK30 and moves to the next row. Do the same rewriting work. When there is no next line, the flow branches from SK80 to the left and returns to SK20, then SK again.
At 20, the rewrite time wait state is entered.

FIG. 12 shows an example of the hardware configuration of the management system. This system example includes a database 200 in which a storage unit is stored, a server 210 that manages the database, a mobile work terminal 220 in which a processing unit is stored in a warehouse for performing mobile work, and instructions for receipt and shipment of products. The receiving / shipping terminal 230 and the router 240 for communicating with the outside of the warehouse are LAN
(Local Area Network). Also,
Each terminal has an input device, a display,
A printer or the like is connected. Here, the input device refers to an input device such as a keyboard and a mouse. The display means a CRT (Cathode Ray Tube), a liquid crystal display device, or the like.

The storage unit or database is a non-volatile memory such as a hard disk device, a magneto-optical disk device, a flash memory, a read-only recording medium such as a CD-ROM, a volatile memory such as a RAM, or the like. It is composed of a combination of. Same for each terminal.

This management system is suitable for managing inventory of fruits, especially bananas, but can also be used for flowers, fruits and vegetables, meat and fish. For example, when used for flowers, the flowering rate may be used as a property that changes with time to characterize the product, and may be set to 1.0 for a hard bud and 5.0 for a fully flowered state. When used for meat, the fact that the color of the meat surface changes over time is used, and the color of the meat surface is used as a parameter indicating the property of the product, and the color immediately after slaughter is 1.0 The color just before decay should be 6.0 mag. An index suitable for each product may be used as a parameter expressing the property. Furthermore, not only the property that can be grasped by observation from the outside, but also the property obtained by a predetermined rule according to the passage of time from the manufacturing date and time may be used.

Furthermore, this management system can also be used for processed products. For example, bananas are in almost the same condition as they were harvested locally at the domestic import stage, with dozens of bananas attached to one bunch. However, before shipping to each store, processing is added to subdivide into the number of sales units. It may also be processed into cut fruits. No matter how it is processed,
Since the property whose characteristics change from moment to moment does not change, the above system can be used for inventory management of processed products. For meat, the control system can be used at any stage of processing, from slaughtered to ground meat.

The rewriting frequency of the property data may be changed as needed, and the rewriting frequency per day is not particularly limited. It is desirable to rewrite the data before the start of management work or during breaks of workers.

The products described in this specification are not limited to products that are directly subject to transactions with the outside. For example, an intermediate raw material that is generated in the middle of a processing process or an article that is in the process of being processed, and an article that is indirectly a transaction target even if it is not a transaction product with the outside is included in the product. .

Although the invention has been described above as a system, it may be understood as a program for causing a computer to execute processing equivalent to each of the above inventions or desirable modifications thereof. For example, a program for causing a computer to execute a process for deciding an arrangement of a commodity inventory with a property change in a warehouse, and an inventory storage for specifying the contents of the commodity inventory and the storage location of the commodity inventory in the warehouse. A function, a movement candidate specifying function for specifying one or more movement candidates based on the inventory storage function and a predetermined movement rule, and displaying the specified movement candidate together with a priority order based on the movement rule A movement candidate display function, a work result input function that accepts input of data relating to the inventory actually moved to the storage location among the movement candidates, and a rewrite function that updates the inventory storage using the input data This is a management program for arranging in a warehouse having and.

These programs may be stored in a computer-readable recording medium. Here, the recording medium is a flexible disk, a magneto-optical disk, an R
It refers to a portable medium such as OM and CD-ROM, and a recording device such as a hard disk built in a computer system. Further, the program can be arbitrarily divided, and the divided pieces can be stored in the respective storage media.

In the above embodiment, the management system is provided in the warehouse, but the server and the database may be provided outside the warehouse and may be connected to the terminals in the warehouse by a telephone line, or WAN (Wide Area Network). ) Or via the Internet. Also, the entire system may be configured on a stand-alone computer.

In the above example, each terminal is a general-purpose personal computer, but the terminal is not necessarily limited to them, but a mobile phone or a PDA (Personal Digital Assistant).
e), or even a dedicated network terminal or the like.

The database may be configured as a relational database or may be XML (eXtensible Marl).
It may be configured by a kup Language type database.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and includes design changes without departing from the idea of the present invention.
