When the inventory transition search unit 30 calculates the inventory schedule, the cumulative total data for each month and day data is added to the number data of the inventory data for each type of material number, and the cumulative total data for inventory is subtracted. Is calculated. However, as mentioned above, the cumulative total data is generated for each order accuracy data, and the cumulative total data is generated for each order accuracy data.
For example, when one of the order accuracy data and one of the order accuracy data are respectively specified by the user from the external input means such as the keyboard 110, the inventory transition search unit 30
Calculates the planned stock quantity data corresponding to the combination of the order accuracy data and the order accuracy data.

Further, when the inventory transition search unit 30 searches for a shortage material, as described above, the inventory schedule for each material number and each month and day data calculated according to the combination of the order accuracy data and the order accuracy data. Is compared with a predetermined lower limit number, and if the number data to be stocked is smaller than the lower limit number, the material number, date data, number data, etc. are notified on the display output of the display 112 or the like. .

The inventory transition extracting unit 31 also corresponds to a processing function of the computer system corresponding to the application program for material requirement planning, and has a function of calculating a stock amount as an amount calculating unit and a function of searching for surplus materials as a surplus notifying unit. And

When the inventory transition extracting unit 31 calculates the inventory amount, one of the order accuracy data and one of the order accuracy data are specified as described above, and the inventory transition search unit 30 is specified.
Is calculated, the stock data is calculated by multiplying this by the unit price data of the material data corresponding to the material number.

When the inventory transition extracting unit 31 searches for surplus materials, the inventory amount data calculated as described above is compared with a predetermined upper limit amount, and the inventory amount is larger than the upper limit amount. Then, the material number, the date data, the amount data, and the like are notified by data output on the display 112 or the like.

The various means as described above are realized by using hardware such as a keyboard 110 and a display 112 as necessary. The main means corresponds to software stored in an information storage medium such as a RAM 104. This is realized by the operation of the CPU 101, which is hardware of a computer.

Such software includes, for example, a reference information file 21 for storing material data and configuration data, a current storage file 22 for storing current storage data, and production plan data in which order accuracy data is set. A production plan file 23 for storing data, an order information file 24 for storing order status data in which order accuracy data is set, a demand file 26 for storing delivery schedule data in which order accuracy data is set, and order accuracy data Is a supply file 27 for storing the data of the scheduled storage, the data of which is set, and an in / out file 29 for storing the data of the planned incoming and outgoing, in which the order accuracy data and the order accuracy data are set. Building on the device, Various files 21 by the main expansion process
24 and 24 are generated from the stored data and registered in the demand file 26 and the supply file 27, and the data are stored in the demand files 26 and 27. Generating data of scheduled entry / exit data for each material number and registering the data in the in / out file 29, calculating a planned inventory from the scheduled entry / exit data stored in the in / out file 29, and determining a shortage material from the scheduled entry / exit data. It is stored in an information storage medium such as the RAM 104 as a control program for causing the CPU 101 or the like to execute processing operations such as searching, calculating a stock amount from expected entering / leaving data, and searching for surplus materials from the expected entering / leaving data. ing.

In the configuration described above, the data processing device 100 of the present embodiment is also
Similarly, when various data are registered in the various files 21 to 24 by the user, the required development processing of the required development engine 25 generates outgoing / incoming scheduled data, and the data is registered in the demand / supply files 26 and 27. Is done.

However, the data processing device 1 of the present embodiment
In the case of 00, as shown in FIGS. 3 and 4, the production plan data is set with the order accuracy data indicating the accuracy with which the material can be delivered, and the order status data includes the order accuracy data with the accuracy with which the material can be received. Fig. 5
As shown in FIG. 6 and FIG. 6, order / order accuracy data is also set in the outgoing / incoming scheduled data.

In this case, the scheduled development data and the planned warehousing data are generated from the production plan data by the required development processing. Therefore, these warehousing / warehousing data include the order accuracy data of the production plan data as the order / order accuracy. Data is set as data. However, since the order status data is also incorporated in the scheduled arrival data, the order accuracy data of the order status data is also set as the order accuracy data of the scheduled incoming data.

When the outgoing / incoming scheduled data in which the order / order accuracy data is set as described above is registered in the demand / supply files 26 and 27, as shown in FIG. , Scheduled entry / exit data is generated by the calculation processing of the inventory calculation engine 28 and registered in the in / out file 29.

For example, as shown in FIG. 5, as the scheduled release data of the material β, when “11/25”, which is the first month and date, has an order accuracy of “1” and a quantity of “5”, FIG. Thus, in the entry / exit data of material β, the first month
Since the quantity data of the scheduled delivery of “1” of “5” is “5”, the cumulative data of the delivery is also “5.” However, this accuracy “1” is the highest order, and other data on the same date Since there is no delivery schedule, the number data and the delivery total data of accuracy “2 to 4” below “11/25” are also “5”.

Then, as shown in FIG. 5, if the delivery schedule data of the material β indicates that there is a delivery schedule of “10” with an order accuracy of “1” on the next day “11/30” on the next day, “FIG. As shown in the entry / exit data of the material β, the number data of the scheduled delivery from the date “11/30” with an accuracy of “1” is “10”, and the cumulative delivery data is “15 (= 10 + 5)”. Become. Further, since there is no other delivery schedule on this date, the lower accuracy “2”
The number data of "~ 4" is also "10", and the total number of goods shipped is also "15"
Becomes

Similarly, the storage schedule of the scheduled entry / exit data is also generated from the scheduled storage data of the material β. However, as shown in FIG. Since there is a number "5" at 0 and a number "5" at order accuracy "1", as shown in FIG.
The number data and the cumulative total data of the storage schedule with the accuracy “0” of “11/25” are “5”.
The quantity data and the total data of the scheduled storage of 4 ”are“ 10 ”
Becomes

When the scheduled entry / exit data is generated and registered in the in / out file 29 in this manner, the data processing apparatus 100 according to the present embodiment, for example, converts the work menu displayed and output on the display 112 to the keyboard. The selection by manual operation of the mouse 110 or the mouse 111 enables the calculation of the stock schedule, the search for the shortage material, the calculation of the stock amount, the search for the surplus material, and the like.

When calculating the stock schedule, the user can set the processing conditions such as material number, date and time data, order accuracy data, order accuracy data, etc.
External input such as 0. Then, the cumulative total data is added to the number data of the inventory data and the cumulative total data is subtracted under the corresponding processing conditions, and the number data of the planned inventory is calculated.

The inventory schedule calculated in this way is notified to the user on the display output of the display 112 in accordance with the processing conditions. Therefore, for example, the user confirms when and how many inventory of a certain material will become. can do. In particular, since the user can specify order / order accuracy data as desired, the user can check the stock schedule of the material in accordance with the accuracy of delivery / reception.

When searching for a shortage material, for example, a user inputs the order / accuracy data and the lower limit quantity from the keyboard 110 or the like as processing conditions. Then, in accordance with the combination of the externally input order / order accuracy data, the planned stock quantity data for each material number is sequentially calculated for each month and day data, and the calculated stock plan is sequentially calculated as the lower limit quantity. Be compared.

At this time, if a smaller number of inventory plans than the lower limit number are detected, the material number, date data, quantity data, etc. are notified on the display output of the display 112, etc. The user can confirm whether to do so in accordance with the accuracy of delivery / reception. Although the lower limit number is set as desired, for example,
If "0" is set, a missing item can be detected.

When calculating the stock price, the user inputs processing conditions such as material number, date data, order accuracy, order accuracy, and the like from the keyboard 110 or the like as desired. Then, the quantity data of the stock to be stocked is calculated under the corresponding processing conditions, and then multiplied by the unit price data of the material data corresponding to the material number to calculate the amount data of the stock. The user can confirm the amount of money for each month and day.

In particular, since the user can specify order / order accuracy data as desired, the stock amount of the material can be confirmed in accordance with the accuracy of delivery / reception. As described above, the transition of the number of stocks and the amount of stock, which are calculated by the user selecting various conditions as described above, are displayed on a display 112 as a graph or a list for each month and day, as shown in FIGS. Can also be displayed and output.

When searching for surplus materials, the user inputs externally using the keyboard 110 or the like as processing conditions of order / order accuracy data and the upper limit amount. Then, the inventory amount for each material number is sequentially calculated for each month and day data by the combination of the externally input order / order accuracy data,
The inventory amount calculated in this way is sequentially compared with the upper limit amount.

At this time, if a stock amount larger than the upper limit is detected, the material number, date data, amount data, and the like are reported on the display output of the display 112 or the like. The user can check when the amount becomes excessive in accordance with the accuracy of the delivery / reception. In addition, the surplus search is sequentially performed on all the materials. However, since the surplus detection condition is not the number but the amount, the surplus inventory can be detected from all the materials having different unit prices.

The present invention is not limited to the above-described embodiment, but allows various modifications without departing from the gist of the present invention. For example, in the above-described embodiment, the delivery / receipt accuracy data is set in the delivery / reception schedule data generated by the required development process, and it is possible to detect a shortage material or a surplus material in accordance with the delivery / reception accuracy. Although illustrated, it is also possible to detect a shortage material or a surplus material from the outgoing / incoming scheduled data in which outgoing / incoming accuracy data is not set.

However, it is also possible to form each of these various means as unique hardware, and it is also possible to store a part of the various means as software in the RAM 104 or the like and form a part as hardware.

Further, in the above-described embodiment, the current list image is automatically generated in correspondence with the current date and time that the date and time generating means 26 constantly generates. It is also possible to generate a list image at an arbitrary date and time corresponding to the above.

In the above embodiment, the software previously installed in the HDD 105 from the CD-ROM 108 or the like is stored in the RAM 10 when the data processing apparatus 100 is started up.
4 is assumed to be read by the CPU 101, and the software stored in the RAM 104 is assumed to be read. It is also possible to keep.

Further, the software is stored in the FD 106 or the CD-ROM 108 which is an information storage medium which can be handled alone, and the FD 106 and the HDD 105
Although it is possible to install software in the AM 104, it is also possible for the CPU 101 to directly read the software from the FD 106 or the like and execute the processing operation without performing such installation.

That is, when various means of the data processing apparatus 100 of the present invention are realized by software, the software only needs to be in a state where the CPU 101 can read and execute a corresponding operation. It is also possible to form a control program for realizing the various means as described above by a combination of a plurality of software. In this case, the information storage medium which is a single product has the data processing device 100 of the present invention. It is sufficient to store only the minimum necessary software for realizing the above.

For example, the data processing device 100 on which an existing operating system is mounted is provided with a CD-RO
In a case where application software is provided by an information storage medium such as M108, the data processing apparatus 10 of the present invention is used.
Since the software that realizes the various means of No. 0 is realized by a combination of application software and an operating system, software of a part that depends on the operating system can be omitted from the application software of the information storage medium.

The method of supplying the software described on the information storage medium to the CPU 101 is not limited to loading the information storage medium directly into the data processing device 100. For example, the above software is stored in the information storage medium of the host computer,
It is also possible to connect this host computer to a terminal computer via a communication network, and to supply software from the host computer to the terminal computer by data communication.

In the case described above, the terminal computer can execute the stand-alone processing operation with the software downloaded to its own information storage medium. However, the terminal computer can perform real-time processing with the host computer without downloading the software. It is also possible to execute a processing operation by data communication. In this case, the entire system in which the host computer and the terminal computer are connected by the communication network is the data processing device 1 of the present invention.
This would be equivalent to 00.
