Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of providing inventory information of steel products, a computer program, and a method of manufacturing steel products, and more particularly to processing for emergency orders.

[0002]

2. Description of the Related Art Conventionally, when an article is produced by a company that produces articles (hereinafter, simply referred to as "company, etc."), it is usually within the same specification or permissible range that a customer's order can be produced collectively. The so-called lot production is performed to collectively produce the orders of a plurality of customers having the specifications in. Therefore, products with different delivery dates are mixed in one lot, and customers who do not have a sufficient delivery date can complete the product at the same time, while customers who have a sufficient delivery period can store the products in a warehouse for a certain period of time. Shipping.

When the production amount of one lot has a lower limit value, normally, it is necessary to wait until a large number of orders having the same specifications or specifications within the allowable range that can be produced collectively are gathered. To produce. However, due to customer specifications or delivery dates, there may be cases where only orders below the lower limit are gathered by the production start date.In that case, the product will be produced at the lower limit and products without orders from customers will Excess inventory.

[0004]

Conventionally, when a lot of a product having a lower limit of the production amount is manufactured in a lot, the product is sold to the production plan unless the excess inventory occurs in the above situation. It has already been decided at the planning stage. Therefore,
When an emergency purchase request is received from a customer, first, it is examined whether it is possible to deal with the above-mentioned excess inventory,
If possible, the stock will be shipped as a product.

On the other hand, when the excess stock cannot be dealt with, the company, etc.
Or, the customer has been waiting for the completion of the product in the next and subsequent lots in accordance with the specifications, thereby responding to the urgent purchase request. However, in the former case, companies are often forced to make major revisions to their production plans, resulting in increased product costs, which is one of the main factors that pressure companies' profits. It was In the latter case, the customer may be forced to review part or the whole of his / her own production or sales plan, and the company, etc. may buy the customer disproportionately and lose the business with the customer thereafter. ,
There were many cases where I actually lost it.

If the customer's request cannot be satisfied even by the above method, the customer places an order with another company or the like, and the company or the like misses the business opportunity and buys the customer's disfavor. The result is similar to the above.

[0007] Such a tendency is particularly remarkable in the case of producing an article by so-called charge knitting, in which the specifications for each lot, that is, the manufacturing conditions such as the component ratio and the manufacturing temperature are different, and the products are manufactured by a company or a customer. It was one of the problems that must be resolved at an early stage that cannot be overlooked by both parties.

The present invention has been made in order to solve such a problem, and extends the conventional concept of excess inventory in the case of performing lot production of goods after a customer is confirmed, and orders at the planning stage. , Intermediate products at the production stage and in-stock products after production are considered to be equivalent to surplus inventory under certain conditions, and it is possible to satisfy the needs of both original customers and customers who want to make an emergency purchase. By doing so, we aim to gain the trust of customers without missing the current business opportunities, and as a result to stabilize corporate management in the future.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1. FIG. 1 is a block diagram showing the configuration of a virtual inventory sales system according to the first embodiment of the present invention. This virtual inventory sales system uses a customer terminal 1
00, an inventory sales server 200, and an in-house processing server (production management computer) 300. A browser is installed in the customer terminal 100, and a public line (including the Internet) for the inventory sales server 200 1
It is configured to be accessible via 10. The inventory sales server 200 includes an internet processing unit (Web server) 201, an order processing unit 202, a search unit 203, and a storage device 204. In the storage device 204,
Virtual inventory sales information 205 and HP screen information 206 are stored. Details of these pieces of information 205 and 206 will be described later.

The in-house processing server 300 is the central processing unit 3
01 and a storage device 310. The central processing unit 301, based on a program (not shown) stored in the storage device 310, an order receiving processing unit 302, a transfer directing processing unit 303, a production information updating unit 304, a virtual inventory information extracting unit 305, an aggregation / Price update processing unit 307 and timer 3
The processing of each unit of 06 is performed. The timer 306 supplies the virtual inventory information extraction unit 305 and the aggregation / price update processing unit 307 with update triggers at predetermined timings to cause the respective processes to be performed. The storage device 310 stores line number correspondence information 311, production information 312, virtual inventory information 313, and selling price change information 314. Details of these pieces of information 311 to 314 will be described later.

Order processing unit 302 of the in-house processing server 300
When an order input (phone, FAX, written order, etc.) 308 or online order 309 is received, the storage device 310 stores it.
Stored as production information 312. The production information 312 is
This is information that can be used to understand the status of the entire production process related to product production planning, production, inventory, etc., line number, phase, production start (planned) date, customer name, product standard, order quantity, completion (planned) ) It consists of data for each item such as date and delivery date. These data are used to identify individually ordered properties that have been ordered from customers, and also serve as keys for various information or data related to various information. This production information 3
12 is normally deleted on the day after the delivery date when the information becomes unnecessary.

In the production information 312, within the range of data regarding the order quantity of the information, even if the product is sold to an unspecified number of customers other than the original customer for a certain period, the original customer's request can be satisfied. The possible production information 312 is extracted as virtual inventory information 313 by the virtual inventory information extraction unit 305, and at that time, the data item and data regarding the sales deadline are automatically added, and further, the data regarding the sales deadline is corrected as necessary. Virtual inventory information 3 after adding
It is stored in the storage device 310 as 13. At the same time, when the production information updating unit 304 sells the virtual inventory product based on the above-mentioned virtual inventory information 313 to the unspecified large number of customers other than the original customer in whole quantity or in part, the original customer's request is received. New production information, which is new production information that can be satisfied and does not generate surplus inventory products, is created (see line numbers 0101, 0071, and 0102 in FIG. 7 described later), and the same information is stored as new production information 312. Device 3
10, the line number correspondence information 311 that is information about the correspondence between the line numbers of the existing production information 312 and the new production information is created and stored in the storage device 310.

The transfer / direction processing unit 303 is an order processing unit 30.
When an order for a virtual inventory product is received via 2, the predetermined process is performed based on the line number correspondence information 311 and the production information 312, the transfer / transfer process is performed, and the line number is handled as necessary. The information 311 and the production information 312 are updated, and the virtual inventory information extraction unit 305 is driven.

The storage price reference or a specific change price is input to the storage device 310, and the sale price change information 3
It is stored as 14. Aggregation / price update processing unit 30
7 is virtual inventory information 313 and sales price change information 314.
Based on the above, the virtual inventory information is aggregated as necessary, the price is added to it to generate the virtual inventory sales information 205, which is transmitted to the inventory sales server 200 and stored in the storage device 204. In addition, the production instruction unit 315 of the in-house processing server 300
Reads the production information 312 stored in the storage device 310 and gives the production system an instruction for production. It should be noted that the data on the selling price is generally changed to a higher value automatically or manually as the sales deadline approaches. This is because it is possible to surely shorten the delivery time of the product and there is no possibility that the virtual inventory product will be an excess inventory product because the sales destination has already been determined.

FIG. 2 is an explanatory view of the production information 312 on May 20, 2001, for example. In the first embodiment, there is one product manufacturing line, the product standard is two types of X and Y, X is a higher standard of Y, the product is sold by weight, and the delivery date is the day after the completion (planned) day or later. In that case, it is the day after the order is received, and the production plan can be changed until the day before the scheduled production start date. Further, as the production start (scheduled) date, the planned production start date is set if the date is before the calendar date, and the production start date is set if that date or after that date. The completion (scheduled) date is set to the scheduled completion date if the date is before the calendar date, or the completion date if it is or after that date. Further, among the data items, those in which the content of the data is not described in the customer name and the delivery date are the surplus stock products. In addition,
When the time management is possible and deemed necessary due to the characteristics of the product, time management may be performed in addition to the above date management.

Here, the virtual inventory product in the first embodiment means that even if an original customer's order is sold to a large number of other unspecified customers within the order quantity of the original customer, These are orders at the planning stage, intermediate products at the production stage, and in-stock products and surplus in-stock products after the end of production that can satisfy the demand. Then, according to the first embodiment, it is possible to regard the above-mentioned virtual inventory product as a surplus inventory product for a certain period and sell it freely. In this case, the fixed period is the period during which the original sales contract with the customer can be complied with, and during this period, other inventory products, semi-finished products in the production process or planned products can be virtual inventory products. Transfer or direct the product or semi-finished product to the customer. It should be noted that “transfer” means that when a virtual inventory product is sold, the production information of another customer, which is already stored in the storage device 310, is to be sold to the customer who planned to sell the product. It refers to the interrelationship between products or information based on. When the virtual inventory product is sold, the "assignment" is a mutual relation between the production information newly created when the virtual inventory information is created and the product or information based on the production information already stored in the storage device. That is.

FIG. 3 is a flow chart showing a process of extracting the production information which is the target of the virtual inventory product from the production information. This processing is performed by the virtual inventory information extraction unit 305 and the production information update unit 304.

First, the virtual inventory information extraction unit 305 selects a lot to be processed from the lot of the production information shown in FIG. 2 (S1).
0). This is normally selected sequentially from the lowest line number in the production information 312 of FIG. It is determined whether the selected lot can be reproduced by the delivery date (S11). If the selected lot can be reproduced by the delivery date, the product is regarded as a virtual inventory product (S12). For example, as shown in FIG. 4A, even if a certain lot is transferred to another order at the present time, if it can be reproduced by the delivery date, it will be the target of the virtual inventory product. . This includes surplus stock products.

Further, even if the condition of (S11) is not satisfied, the virtual inventory information extraction unit 305 determines whether or not the delivery date can be met by punching with a substitute product (S13). In this judgment, it is necessary to meet the condition that the substitute can be delivered in time by allocating the substitute and the substitute can be reproduced. If these conditions are met, the product is considered as a virtual inventory product (S1).
4). This is because, for example, as shown in FIG. 4B, even if a certain lot is assigned to another order at the present time, it can be supplemented by an alternative item, and the alternative item is assigned to another order. Even if the replacement is performed, if the substitute product can be reproduced by the delivery date, the selected lot is targeted for the virtual inventory product.

Next, when the lot of the production information is the target of the virtual inventory product by the process (S12), the production information updating unit 304 causes the production information updating unit 304 to substitute the product when the lot is sold. It is determined whether there is any (S1
5). If it is determined that there is no substitute, new production information for the relevant lot is added (S1).
6). Further, when the lot of the production information 312 is the target of the virtual inventory product by the processing (S14), and the processing (S
When it is determined that there is a substitute in 15), new production information for allocating the substitute when it is sold is added (S17). Above processing (S10)
(S17) is performed for all lots of the production information 312 (S18).

FIG. 5 is an explanatory diagram of the virtual inventory product extracted by the above process, and FIG. 6 is an explanatory diagram of new production information after the virtual inventory information is created. According to the process of FIG. 3 described above, the line number 0 in the production information 312 shown in FIG.
010, 0030, 0070, 0100 are targets of the virtual inventory product. The reason for this will be described in more detail.

First, line number 0010 in the inventory phase is handled as a virtual inventory product because it is an inventory product for which the customer has not been confirmed, that is, a surplus inventory product. The line number 0030 in the inventory phase is a virtual inventory product for the following reason. That is, the lot with the line number 0030 has a delivery date of June 15, and the number of days required for its production is 31 days. Therefore, it can be re-produced by the delivery date (S11) and becomes a virtual inventory product ( S12). Furthermore, if the lot of row number 0030 is sold, the lot of row number 0100 can be applied as an alternative to direct it. Then, for the orderer A of the lot with the line number 0100, 2
New production information of line number 0101 is added to the planning phase in which production is started from July 1, 001 (S16). If this line number 0101 is completed as a product on July 31, the same year, it will be directed to A, the orderer of line number 0100 in the production phase, and line number 0100 will be completed as a product on May 31, the same year. In this case, it is possible to transfer to B, who is the orderer of line number 0030, and as a result, line number 0030
It is possible to sell the in-stock products to a large number of unspecified customers other than the orderer B within the order quantity.

Similarly, the line number 0070 is a virtual inventory product for the following reason. In other words, the lot with line number 0070 has a delivery date of July 5, and the number of days required for its production is 3
Reproduction is possible by the delivery date because it is 0 days (S1
1) The product becomes a virtual inventory product (S12). In addition, line number 00
If 70 lots have been sold, there is no substitute for allocating it (S15), so add the new production information of line number 0071 to the planning phase that starts production from June 1, 2001. By (S16), when this line number 0071 is completed as a product on June 30, the same year, it can be transferred to F, who is the orderer of the line number 0070 in the inventory phase, and as a result, the inventory of line number 0070. The product can be sold to an unspecified large number of customers other than the orderer F within the order quantity.

Further, the line number 0100 is a virtual inventory product for the following reason. That is, the lot with line number 0100
Since the delivery date is August 5, and the number of days required for the production is 31 days, it is possible to re-produce by the delivery date (S1
1) The product becomes a virtual inventory product (S12). In addition, line number 01
There is no substitute for allocating the lot of 00 when it is sold (S15), so the new production information of line number 0102 is added to the planning phase in which production is started from July 1, 2001 ( S16). When this line number 0102 is completed as a product on July 31, the same year, it is possible to direct it to the orderer A of the production phase line number 0100, and as a result, the line number 0100 becomes May 31, the same year. When completed, the product can be sold to an unspecified large number of customers other than the orderer A within the order quantity.

As described above, the virtual inventory products are extracted from the production information, and the line numbers 0010, 0030, 0070 and 010 are extracted.
As a result of the 0 lot being extracted as the virtual inventory product, the line numbers 0071, 0101, 0102 are added to the production information as new production information, and the production information 312 shown in FIG. 6 is generated.

FIG. 7 is an explanatory diagram of data relating to line numbers for transfer and transfer of the new production information described above. In the above process, the production information updating unit 304 stores, in the storage device 310, line number correspondence information 311 indicating the correspondence between line numbers for transfer and transfer to the virtual inventory information. In the example of FIG. 7, the lot with the line number 0030 is transferred to the lot with the line number 0030, and the lot with the line number 0101 (additional line number) is transferred to the lot with the line number 0100. The lot of line number 0070 (additional line number) is transferred to the lot of line number 0070. Further, the lot of row number 0102 (additional row number) is transferred to the lot of row number 0100. This relationship is stored in the storage device 3 as the line number correspondence information 311.
10 will be stored. Note that when the new production information (line numbers 0101, 0071, 0102) is created, the content itself of the information existing in the production information 312 does not change, but it is transferred or redirected via the line number correspondence information 311. It will be linked to (related to) the line number in the relationship.

The virtual inventory information extraction unit 305 gives a sales deadline to the above-mentioned virtual inventory information 313. The deadline is set according to the following concept.

FIG. 8 is an explanatory diagram for explaining a method of setting the sales deadline of the virtual inventory product. The value of each data item in the figure is an extraction of the corresponding item of the new production information of FIG. 7, and the line numbers 0010, 0030, 0070 and 01.
00 is a virtual inventory product. Here, in the case of the line number 0010, since it is a surplus inventory product, any date may be used as long as it is a date after the completion (planned) date and after the calendar date within the period in which the quality of the product can be maintained. The line numbers 0030, 0070, and 0100 are derived from the relationship between the delivery date of the virtual inventory and the production start (scheduled) date of the planning phase corresponding thereto. That is, if the delivery date is before the production start (planned) date, the sales deadline is the day before the delivery date, and if the delivery date is after the production start (planned) date or the production start (planned) date, the production start (planned)
It will be the day before the day.

For example, in the case of the line number 0030, the delivery date is June 15, and the production of the line number 0101 starts (planned).
Since the date is July 10, the delivery date is before the production start (planned) date, and the sales deadline is set to June 14, which is the day before the delivery date. Further, in the case of line number 0070, the delivery date is July 5th, and the production start (planned) date of line number 0071 is June 1, so the delivery date is after the production start (planned) date. , May 31, which is the day before the production start (planned) of the line number 0071, is set. In the case of line number 0100, the delivery date is August 5, and the production start (planned) date of line number 0102 is July 1, so the delivery date is after the production start (planned) date. , June 30, which is the day before the production start (scheduled) date of line number 0102 is set. The sales deadline can be arbitrarily set as long as it is a day after the completion date of the product until the last day of the sales deadline set by the above method.

FIG. 9 is an explanatory diagram of the virtual inventory sales information 205 created by the aggregation / price update processing unit 307. The aggregation / price update processing unit 307 uses the virtual inventory sales information 313.
And virtual inventory sales information 20 based on the sale price change information
5 is generated and stored in the storage device 204 of the inventory sales server 200. The virtual inventory sales information 205 is composed of data of each item such as line number, product standard, sales amount, sales price (unit price), sales start date, delivery date, and sales deadline. The data is stored in the storage device 204. In addition, the sales deadline of the surplus stock product shown in the line number 0010 does not have to be manually input, or is the range after which the product quality can be maintained if it is the date after the completion (planned) date and the calendar date. Any day may be entered as long as it is

Although there is no corresponding lot in FIG. 9, data items such as product standard, sales start date, delivery date, and sales deadline may be aggregated. In this way, the virtual inventory sales information 205 is aggregated when it can be aggregated or when it should be aggregated, and the correspondence between the row numbers before and after the aggregation is the row number correspondence information (row number aggregation information) 311. It is stored and its history is saved. Further, the order quantity in the virtual inventory information 313 and the virtual inventory sales information 205 indicates the quantity that can be accepted.

As described above, the inventory sales server 200
The virtual inventory sales information 205 generated by the aggregation / price update processing unit 307 is stored in the storage device 204, and becomes a search target from the customer terminal 100. Next, customer terminal 1
The search process from 00 will be described.

FIG. 10 is a view showing an inventory search screen of the customer terminal 100. The customer operates the customer terminal 100,
Enter information such as a user name and password registered in advance to identify the customer. As a result, the HP screen information 206 is read and displayed on the inventory search screen shown in FIG. 10 by the internet processing unit 201 of the inventory sales server 200. Here, the customer inputs the product standard, the desired purchase amount, and the desired delivery date as search conditions, and the search unit 203 of the inventory sales server 200 performs a search process corresponding to the search conditions.

FIG. 11 is a flow chart showing the search processing of the inventory sales server 200. It is determined whether or not the search conditions are all output (S30), and if all are output, a list of all the virtual inventory sales information 205 is output (S3).
1) Display all cases on the customer terminal 100 (S32).
It should be noted that this output of all cases can be performed (unconditionally) by not inputting search conditions.

FIG. 12 shows a display screen of a list of all items in stock at the customer terminal 100 (also an ordering screen).
Here, product standard, sales volume, sales price, sales start date,
The delivery date (after the sales start date) and the sales deadline are displayed. This display screen also serves as an ordering screen, and an order can be placed from this display screen.
Although this display screen shows an example in which the selling price is displayed, the selling price may not be displayed. For example, it may be displayed in a state where an order (or a temporary order) has been placed.

Returning to the flowchart of FIG. 11, when the customer operates the customer terminal 100 and inputs the product standard, the desired purchase amount and the desired delivery date as search conditions (S33), it is determined whether there is a corresponding standard product. Yes (S34). If you determine that there is a corresponding standard product, then
Whether there is a shortage or not is judged in relation to the desired purchase amount (S3).
5). Here, when it is determined that there is a shortage amount and when it is determined that there is no standard product corresponding to the above (S34), it is determined whether there is a higher standard (S3).
8). If it is determined that there is a higher standard, the presence or absence of the shortage is determined with the higher standard incorporated (S35). As described above, the present embodiment has a function of searching for a higher standard when the customer does not have the required product. The search result is displayed on the customer terminal 100 both when there is no shortage and when there is no higher standard. The customer orders the product in consideration of the search result.

FIG. 13 is an explanatory view of the ordering screen of the customer terminal 100. In this example, the breakdown of virtual inventory products is
Line number 0070 is 50 (t), line number 0010 is 10 (t)
And the line number 0030 is 40 (t), the stock amount of the product standard Y is 50 (t), and the stock amount of the product standard X is 50 (t). In this ordering screen, for example, product standard Y
A case will be described in which the purchase amounts of X and X are set to 50 (t) and an order is placed.

FIG. 14 is an explanatory diagram in which the above-mentioned ordering information is made to correspond to the virtual inventory product, and the line number 0070 is 50 (t),
Line number 0010 is 10 (t) and line number 0030 is 40
The order of (t) is taken into the in-house processing server 300. And the production information corresponding to the order,
The virtual inventory information and the virtual inventory sales information are changed.

FIG. 15 is an explanatory diagram of the production information, virtual inventory information, and virtual inventory sales information after the ordered products are ordered. The line numbers 0010 and 0070 are deleted from the production information, and the stock amount for the line number 0030 becomes 120 (t), and the line number 001 from the virtual inventory information and the virtual inventory sales information.
0 and 0070 are deleted, and the order quantity (acceptable quantity) of the line number 0030 becomes 120 (t).

FIG. 16 is a flowchart of the above-mentioned processing after the order is received. This process is performed by the production information updating unit 304.
And the virtual inventory information extraction unit 305. First, a processing target is selected (S20), and it is determined whether the lot has been sold by the sales deadline (S21). If it is not sold, and there is additional information corresponding to the lot, it is deleted (S22). If it is sold, it is determined whether or not the order quantity is equal to the order quantity of the virtual inventory item (S23). When the order quantity is equal to the order quantity of the virtual inventory item, the corresponding virtual inventory item is deleted (S24). Then, the production information corresponding to the virtual inventory item is deleted, and the production plan of the new production information added corresponding to the virtual inventory item is confirmed (S25). If the order quantity is not equal to the order quantity of the virtual inventory item, the order quantity of the corresponding virtual inventory item is changed (S26),
The inventory amount of the production information corresponding to the virtual inventory item is corrected (S27). The above process is repeated for all virtual inventory items (S28).

Next, the relationship between the data in FIG. 15 and the processing in FIG. 16 will be described. Virtual inventory line numbers 0010 and 007
0 is deleted by the above process (S24), and the line numbers 0010 and 0070 of the production information are deleted by the above process (S2).
Deleted by 5). Also, line number 003 for virtual inventory
For the order quantity of 0, 40 (t) will be sold, so processing (S2
According to 7), the stock quantity that can be ordered is 120 (t). At this time, in line number 0030 of the production information, the order quantity does not change, but the stock quantity is 120 (t), so the stock quantity is written by the process (S28). As a result of such processing, the data of FIG. 15 is obtained. Production information 31
In 2, the inventory quantity is not specified (row numbers other than the row number 0030 in the above example), and the order quantity and the inventory quantity are the same.

In the processing of FIG. 16, the line number 0030 of the virtual inventory item is after the above sale (sale of 40 (t)),
If it is not sold further by the sales deadline (June 14th), the line number 003 is obtained by the above processing (S22).
The line number 0101 which is additional information for 0 will be deleted.

FIG. 17 is a flow chart showing the processing when the production information order is delivered. This processing is performed by the production information updating unit 304 and the virtual inventory information extracting unit 305. First, a processing target is selected (S30). This processing target is selected as the corresponding processing target when the date of this processing corresponds to the day after the delivery date. It is determined whether the order quantity and the inventory quantity of the processing target match (S31). If the ordered quantity and the stock quantity match, the processing target is to be delivered and deleted from the production information (S32). If the order quantity and the stock quantity do not match and are insufficient, it is assumed that the corresponding target stack is allocated based on the line number correspondence information 311, and the stock quantity for the allocated quantity is set. Subtract and enter (S
33). Then, the production information of the corresponding processing target is deleted (S32). The above processing is repeated for all objects (those on and after the delivery date) (S34).

FIG. 18 is an explanatory diagram showing the contents of production information, virtual inventory information, and virtual inventory sales information as of June 16, 2001. The order of line number 0030 (customer B: delivery date June 15) has been delivered and deleted (S32). And when delivering, line number 0030
40 (t) of product X to customer B of
Of the 160 (t) of 0, 40 (t) is transferred to the customer B, and the inventory quantity of the line number 0100 is 120 (t) (S33). Also, line numbers 0020, 0040, 005
The items 0 and 0060 are also delivered and deleted (S32). When the production information is changed in this way, the production instructing unit 315 gives a production instruction to the production system based on the changed production information 312 to produce a steel product, for example, a thick plate.

In the first embodiment, the virtual inventory information shown in FIG. 3 is generated only once, but it is assumed that the virtual inventory information is automatically generated at a predetermined cycle by the timer 306. .

In the first embodiment, a simple example has been described for simplifying the description, but in reality, the number of order information items (production information) is about tens of thousands, and iron In case of steelmaking stage, converter stage lot,
There are lots of lots such as lots at the stage of continuous casting, and combination processing and replacement processing of those lots are performed, virtual inventory sales information is generated, and the conventional concept of excess inventory is expanded. Therefore, it is possible to quickly respond to urgent orders.

In the first embodiment, an example in which the functions constituting the present invention are distributed to the stock sales server and the in-house processing server has been described, but the present invention is not limited to this. That is, there are various possible combinations of how to realize these on a computer as long as there are individual required functions, and they can be appropriately changed within design items by a computer engineer / steel manufacturing engineer. For example, the inventory sales server and the in-house processing server may be realized by a single computer, or, for example, conversely,
Production controllable from the in-house processing server may be divided into a separate computer.

[0058]

As described above, according to the present invention, a customer other than the ordering customer is based on the production information of the steel product which is in the production schedule, in production or already produced according to the order from the customer. Since the inventory sales information for selling the inventory to the customer is generated and the inventory sales information is sent in response to the request from other customers, the conventional method in the case of performing the lot production of the goods after the customer is confirmed The concept of excess inventory is expanded, and orders in the planning stage, intermediate products in the production stage, and in-stock products after production are considered to be equivalent to excess inventory under certain conditions, and we want to make an emergency purchase with the original customer. It makes it possible to satisfy the demands of both customers, gain the trust of customers without missing the current business opportunities, and as a result, it is possible to stabilize corporate management in the future. There is.
