DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cost management apparatus for centrally managing costs calculated by various departments for products at one place.

[0002]

2. Description of the Related Art In a company that manufactures various products such as electronic devices such as transmission devices and their components, and intangible products such as software programs (hereinafter simply referred to as products), the cost of each product is low. It is estimated by various departments according to the progress of commercialization.

That is, for example, the cost of a product is first roughly calculated in the production management department. This calculated cost is generally called a rough estimate. Next, in the business planning department, it is estimated more accurately. This is commonly referred to as an accounting estimate. Next, when the process proceeds to the product design stage, the cost of the product is more accurately estimated by a known tool such as a cost estimation tool in the design department. This is called a technical quote. Further, when the actual sales stage is completed after the design, a cost called a purchase limit is calculated in the purchasing department. Finally, in the purchasing department, a cost of a fixed value close to the actual selling price is determined.

[0004] As described above, since the costs of various accuracy levels for one product are calculated in various departments, if the costs are stored and managed independently for each department, for a certain product, This is inconvenient when one wants to know the most accurate cost calculated at that time. This is because it is necessary to inquire from the purchasing department to the production management department in order as to whether or not the cost of the product has been calculated, and to obtain the cost if the cost has been calculated.

In order to solve such inconvenience, a database for storing the cost of each product is provided, and when the cost is calculated in each department, the calculated cost is registered in the database as the cost of the product. When it is desired to know the cost, it is considered that a database is searched to obtain the cost of a corresponding product. That is, if a rough estimate is calculated for a certain product A by the production management department, it is registered in the database as the cost of the product A, and if an estimate is calculated by the business planning department, the product in the database is calculated. The approximate estimate of A is updated, and if the technical estimate, purchase limit, and final value are calculated in the design department and purchasing department in the same manner, the cost of the product A in the database is updated accordingly. In this way, if the cost of the product A is retrieved from the database at a certain time, the most accurate cost obtained at that time can be obtained.

[0006]

However, in actuality, there is a time lag between the time when the cost is calculated and the time when the cost is registered in the database. Before it is registered in the database, the engineering department calculates the technical estimate and registers it in the database, and then the business planning department registers the estimate in the database. There is a problem that the cost with the highest accuracy is rewritten with the cost with the lower accuracy, and it becomes impossible to refer to the cost with the highest accuracy among the calculated costs.

[0007] The present invention has been proposed in view of such circumstances, and its object is to provide the most cost-effective method of registering individual products in a database, even if registration operations for the costs with different levels of accuracy are performed in random order. It is an object of the present invention to provide a cost management device that can reliably refer to a cost with a high accuracy level.

[0008]

In order to achieve the above-mentioned object, the cost control device of the present invention is used for products in various departments.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1 , a cost control device 7 according to one embodiment of the present invention comprises a cost storage database 70, cost registration means 71, cost reference means 72, and communication means 73, and is installed in a production management department. Terminal 2, installed in the business planning department 3, terminal 4 installed in the design department, terminal 5 installed in the purchasing department, and other terminals 6.

The cost accumulation database 70 is a database for accumulating one type of cost with an accuracy level added for each product. As shown in the figure, for each product, data for identifying the product (book (Product name in the embodiment) 701
, Cost 703, and accuracy level 702 of this cost 703
Are stored in the cost record 700.

FIG. 3 is a flowchart showing a processing example of the cost registering means 71, and FIG. 4 is a flowchart showing a processing example of the cost reference means 72. The operation of this embodiment will be described below with reference to the drawings. The cost registration request uses the format shown in FIG. 2A, and the cost reference request uses the format shown in FIG.
The format shown in (b) is used.

For a certain product, the production management department, business planning department, engineering department, and purchasing department calculate the cost,
From the terminals 2 to 5, “Registration” is entered in the processing type 200 in FIG.
When a cost registration request in which an accuracy level corresponding to the cost calculated in 02 and the accuracy level 203 is set is received, the communication means 73 of the cost management device 7 receives the cost registration request, and the processing type 200 registers the registration. Therefore, the received cost registration request is notified to the cost registration means 71.

[0015] The cost of registration means 71, as shown in FIG. 3,
First, the cost accumulation database 70 is searched using the product name 201 in the cost registration request as a key (S31). And
If the search for the cost record 700 having the same product name is successful (YES in S32), the found cost record 7
Compare the accuracy level 702 in 00 with the accuracy level 203 in the cost registration request. If the former is larger than the latter, that is, if the cost of the accuracy level higher than the accuracy level requested for registration has not been accumulated in the cost accumulation database 70. BA (S
33, the accuracy level 702 and the cost 703 in the searched cost record 700 are updated with the accuracy level and the cost of the registration requested (S34). Then, the registration completion message is returned to the communication means 73 (S3
7).

However, if the accuracy level 702 in the retrieved cost record 700 is higher than the registration-requested accuracy level, that is, the cost with an accuracy level higher than the registration-requested accuracy level has already been stored in the cost storage database 70. If (NO in S33), the cost accumulation database 7
0 is not updated, and the registration rejection message
(S35).

Therefore, for example, when a request for registration of a technical estimate of accuracy level 3 is made for a product for which an estimate of accuracy level 4 has already been registered in the cost storage database 70, the product corresponds to that product. Cost record 70
While the cost 703 in 0 is updated with the technical estimate requested for registration and the accuracy level 702 is updated to accuracy level 3, the cost record 700 is updated when there is a request for registration of the rough estimate for accuracy level 5. No registration rejection message will be returned.

[0018] On the other hand, in the search processing in FIG. 3 S31,
If the search for the cost record 700 having the same product name has failed (NO in S32), the cost registering unit 71 newly generates the cost record 700 and replaces the product name requested for registration with the product name 701 with the accuracy level. The accuracy level requested to be registered in 702 and the cost requested to be registered are set in the cost 703 and registered in the cost accumulation database 10 (S3).
6). Then, the registration completion message is returned to the communication means 73 (S37).

Therefore, for example, when a cost registration request including the product name, the cost (approximate estimate), and the accuracy level 5 is received from the terminal 2 and the cost record 700 corresponding to the product name does not exist, the registration to the product name 701 is performed. The requested product name is registered in the accuracy level 702.
Is registered in the cost accumulation database 70 in which the approximate estimate requested to be registered in the cost 703 is set.

The communication means 73 transmits the registration completion message or the registration rejection message returned from the cost registration means 71 to the terminals 2 to 5 which are requesters of the cost registration, and informs that the requested cost registration has been completed or the registration has been completed. Tell that you refused.

Next, the operation for referring to the costs stored in the cost storage database 70 will be described.

From the terminals 2 to 5 or the other terminals 6 installed in each section, “reference” is added to the processing type 300 in FIG.
When a cost reference request in which the name of the product to be referred to is set in the product name 301 is sent, the communication means 73 of the cost management device 7 receives the cost reference request, and the processing type 300 indicates the reference. Cost reference request 7
Notify 2.

The cost reference means 72, as shown in FIG. 4,
First, the cost accumulation database 70 is searched using the product name 301 in the cost reference request as a key (S41). And
If the search for the cost record 700 having the same product name has failed (NO in S42), an error message is returned to the communication means 73 (S43). The communication means 73 transmits this error message to the cost reference requesting terminals 2 to 6 to notify that the cost of the corresponding product is not registered.

On the other hand, a cost record 7 having the same product name
If the search for “00” is successful (YES in S42), the cost 703 registered in the cost record 700 is
3 (S44). The communication means 73 transmits the cost returned from the cost reference means 72 to the cost reference request source terminal 2.
To 6. Note that the accuracy level is 70
2 may be configured to be returned and transmitted.

[0025]

As described above, according to the cost control device of the present invention, the following effects can be obtained.

A cost accumulation database for accumulating only one type of cost with an accuracy level added for each product;
At the time of registration, the cost of the product requested to be registered was registered in the cost accumulation database on the condition that the cost with an accuracy level higher than the accuracy level requested was not accumulated in the cost accumulation database. Even if registration requests for different costs are made in any order, lower-precision costs will not overwrite higher-precision costs, and the highest-precision cost at that time will always be used when searching. It will be possible to refer to it.

Since the accuracy level is added for each product and only the cost of one accuracy level is stored and accumulated, the required capacity of the database can be reduced.
