Therefore, the detailed description about them may be omitted.

<Embodiment>
Hereinafter, the requirement calculation apparatus and requirement calculation method according to the present embodiment will be described.

<Configuration>
Products that have individual orders according to specifications required by customers and that require manufacture with a relatively short delivery time are generally handled with inventory of parts. However, “parts” and “quantity of parts” are not determined until the design according to the specifications required by the customer is completed.

In this regard, although the inventory management has been optimized by arranging parts in advance by the method described below, there may still be a problem of defective inventory (excess inventory) or shortage.

For example, in the conventional method, before the details of the order are determined, the number of arrangements is calculated from the past results, the demand forecast or the order estimate, and the parts are ordered. Then, after the details of the order are finalized, a deletion process is performed. With this method, there may be a shortage due to unforeseen or defective inventory (excess inventory).

Also, for example, after receiving an order, we will arrange parts in order from the completed unit of the product. In this method, arrangements may not be made in time and missing items may occur.

Also, for example, the product is divided into standard units and custom-made units, and the custom-made units arrange parts after the order details are finalized. In this method, there may be a case where a custom unit is not in time and a shortage occurs.

As described above, in the conventional method, when there are specifications that are determined at the stage of determining the details of the specifications in addition to the specifications determined at the time of receiving an order, if the specifications are determined in stages, the determined specifications are partially It is not possible to calculate the required quantity by applying it.

This embodiment shown below is for individual orders according to specifications required by customers, and when the specifications of products that are required to be manufactured with relatively short delivery times are determined in stages. Suitable for parts arrangement and proper inventory management.

FIG. 1 is a diagram for explaining an outline of a required amount calculation method according to this embodiment.

As illustrated in FIG. 1, in the requirement calculation method according to the present embodiment, first, specific specification values corresponding to a request from a customer are determined for a part of product specification items from which product information is extracted. To do. Here, the specification value is the contents of the customer request determined for each item of the product specification, and the design requirement (stainless steel, color stainless steel, etc.) and the operation specification requirement (two-speed shift, This is a value indicating the presence or absence of a voice announcement or the like. Then, based on the parameterized configuration information, the type of component and the number of components necessary for the determined specification value are determined (component development).

On the other hand, for the specification item for which the specification value has not been determined, a part is selected from the extracted part candidates based on the predicted value based on the demand prediction information, and the type of component and the number of components are determined.

And for both cases, the calculation result of required amount is output. Such an operation is repeated up to the end part.

As described above, in the requirement calculation method according to the present embodiment, for each specification item of the product that can be requested by the customer, the type of component and the number of components for the specification value requested by the customer are parameterized in advance. deep. When the specification value of the specification item is determined at the specification detailing stage after receiving an order, the type of component and the number of components are calculated based on the parameter of the determined specification value. On the other hand, if the specification value of the specification item is not fixed at the specification detailing stage after receiving an order, the type of component and the number of components are calculated based on the predicted value based on the demand prediction information.

According to such a method, the proportion of calculation of the types of component parts and the number of component parts by the demand forecast is gradually reduced in accordance with the ratio of the specification values determined at the stage of specification refinement after receiving an order. Therefore, the occurrence of defective stock (excess stock) or shortage can be reduced as compared with the conventional case.

FIG. 2 is a diagram conceptually illustrating a configuration for realizing the requirement calculation apparatus according to the present embodiment.

As illustrated in FIG. 2, the requirement calculation device includes a requirement calculation unit 11, a calculation result output unit 12, a calculation result storage unit 13, a specification information storage unit 21, a product information storage unit 31, A configuration information storage unit 32 and a demand prediction information storage unit 42 are provided.

The required amount calculation unit 11 determines whether or not the specification value is determined for each specification item of the product to be produced by the order. Further, the required amount calculation unit 11 calculates a required amount that is a required amount of a part for each of the specification item for which the specification value is fixed and the specification item for which the specification value is not fixed.

Also, the calculation result output unit 12 outputs the calculation result of the requirement in the requirement calculation unit 11. For example, the calculation result may be output to the inventory management system 50 that is an external system. Then, the stock management system 50 orders the material based on the calculation result of the required amount in the required amount calculation unit 11 to the material system 60 which is an external system, for example. The material may be received based on the calculation result of the required amount in the amount calculation unit 11.

The calculation result storage unit 13 stores the calculation result of the required amount. In addition, the specification information storage unit 21 stores, for example, a specification value registered in the negotiation system 20 that is an external system as a specification value requested by a customer. The timing for acquiring the specification value from the business negotiation system 20 may be any time after the order is received. However, the earlier the timing for acquiring the specification value, the more time it can be taken to arrange the product and the shortage of the product can be suppressed. The later the time to acquire, the higher the proportion of specifications that have been confirmed, and a more reliable arrangement will be possible. The product information storage unit 31 stores product information registered in the design system 30 that is an external system, for example.

Further, the configuration information storage unit 32 stores configuration information registered in the design system 30 that is an external system, for example. Moreover, the demand prediction information storage part 42 memorize | stores the demand prediction information registered into the sales system 40 which is an external system, for example.

The processing circuit 102 a may execute a program stored in the storage device 103. In other words, for example, a central processing unit (CPU), a microprocessor, a microcomputer, or a digital signal processor (DSP) may be used.

When the processing circuit 102a executes a program stored in the storage device 103, the requirement calculation unit 11 is realized by software, firmware, or a combination of software and firmware. Note that the function of the requirement calculation unit 11 may be realized, for example, by cooperation of a plurality of processing circuits.

Software and firmware may be described as programs and stored in the storage device 103. In that case, the processing circuit 102a reads out and executes the program stored in the storage device 103, thereby realizing the above function. That is, the storage device 103 may store a program that, as a result, is executed by the processing circuit 102a, realizes the above functions.

Further, the processing circuit 102b may be dedicated hardware. That is, for example, a single circuit, a compound circuit, a programmed processor, a parallel programmed processor, an integrated circuit (application specific integrated circuit, that is, ASIC), a field-programmable gate array (FPGA), or a combination thereof. It may be.

FIG. 15 is a conceptual diagram when the configuration information exemplified by the matrix in FIG. 7 is expressed by an actual configuration image.

FIG. 16 is a conceptual diagram when the configuration information exemplified by the matrix in FIG. 8 is expressed by an actual configuration image.

The above will be specifically described with reference to FIG. The child parts (component parts) whose parent part number is “B10000” have six parts whose child part numbers are “B11001”, “B12001”, “B13001”, “B00738”, “B00773”, and “B00657”. Defined. In the column defining the number of child parts, the number of necessary child parts is described numerically for each requested specification value code of each specification code.

More specifically, when the required specification value code of the specification code A001 is “greater than 4 and less than or equal to 8”, one “B11001” and two “B00738” are child components (components). , “B00773” and two “B00657” are defined. Here, it is determined that there are zero (unnecessary) child parts (components) that are not described with numerals and are blank.

Further, when the required specification value code of the specification code A001 is “greater than 8 and 11 or less”, as the child parts (component parts), one “B12001”, two “B00738”, “B00773” "And two" B00657 "are defined.

Further, when the required specification value code of the specification code A001 is “greater than 11 and 15 or less”, “B13001” is one, “B00738” is three, and “B00773” is a child component (component). ”And three“ B00657 ”are defined.

In more detail, referring to FIG. 8, the child parts (component parts) whose parent part number is “B12001” are child parts numbers “B00867”, “B00122”, and “B00382”. One part is defined. In the column defining the number of child parts, the number of necessary child parts is described numerically for each requested specification value code of each specification code.

More specifically, when the required specification value code of the specification code A005 is “1”, it is defined that one “B00867” and two “B00122” are required as child parts (components). . Here, it is determined that there are zero (unnecessary) child parts (components) that are not described with numerals and are blank.

As illustrated in FIG. 9, as the demand prediction information, a predicted number for each model number at a certain production time is registered. In the case of FIG. 9, “200 units” for product A, “50 units” for product B, and “50 units” for product C are registered as the predicted number of production in June 2015, for example.

Furthermore, the predicted value of the specification value that can be requested by the customer is registered as the demand prediction information for each specification code of each model number. In the case illustrated in FIG. 10, for the specification code A005 of product A, the probability that the customer is requested to specify “specific value code = 1” is “50%”, and “specification value code = 2” is the customer. The probability required for “25%” is “25%”, and the probability that the customer requires “specification value code = 3” is “25%”. The name of the specification item is automatically converted into a code that can be recognized by the sales system 40 as a specification code, and the specification value is stored as a specification value code.

<Action>
FIG. 11 is a flowchart illustrating the operation of the requirement calculation apparatus according to this embodiment. In the following description, the case where the model number is “product A” will be described as an example. However, the required amount calculation is performed for all the model numbers for which the required required amount is to be calculated.

First, the requirement calculation unit 11 extracts the predicted number of the target model number and the predicted value of the specification value of the target model number from the demand prediction information storage unit 42 (see step ST111).

Next, the requirement calculation unit 11 receives from the specification information storage unit 21 a specification code corresponding to the specification item requested by the customer and a specification value code corresponding to the specification value requested by the customer in the specification item. Extract (see step ST112).

FIG. 12 is a diagram exemplifying the determination status of the specification value of the specification item in each negotiation when the model number is “Product A” after the steps ST111 and ST112.

As illustrated in FIG. 12, since the predicted number obtained from the demand prediction information in the demand prediction information storage unit 42 is “200”, an ID column up to the predicted number 200 is prepared for each prediction of the production number. The That is, the required amount is calculated until the predicted number is satisfied. Each specification code obtained from the specification information storage unit 21 and a specification value code requested corresponding to the specification code are indicated for each predicted number of units.

In the case illustrated in FIG. 12, since the specification value code up to “ID60” is shown, it can be seen that the number of production during the negotiation is “60”. In addition, when the location where the specification value code is to be indicated is blank, it indicates that the specification value code is not set.

Next, the required amount calculation unit 11 uses the predicted value of the specification value of the model number (product A) to be obtained from the demand prediction information in the demand prediction information storage unit 42, and is a place that is blank as described above That is, a specification value code is set for a specification item for which a specification value is not set (see step ST113).

More specifically, the system determines the specification value code by apportioning the total number of specification value codes that are indefinite within the same specification code by the prediction probability.

The above will be described with reference to FIG. 10 and FIG. 12. In FIG. 12, when the specification value is uncertain in the column of the specification code A005, that is, there are 100 blank portions, the prediction illustrated in FIG. Referring to the value, the probability that the customer is required to specify “specific value code = 1” is “50%”, the probability that the customer is required to specify “specific value code = 2” is “25%”, and “ Since the probability that the customer is required to have “specification value code = 3” is “25%”, the specification value codes in the blank spaces are “specification code = 1”, “specification code 50”, “specification code”. “25 value codes = 2” and “25 specification value codes = 3” are set.

FIG. 13 is a diagram exemplifying the determination status of the specification value of the specification item in each business negotiation when the model number is “product A” after the above processing is performed.

As illustrated in FIG. 13, after the above processing is performed, a calculation target record in which all the specification value codes in all the specification codes are set is created.

The required amount calculation unit 11 tries to extract the first line of the calculation target and determines whether or not extraction is possible (see step ST114). When the calculation target head line cannot be extracted, that is, when the calculation target head line does not exist (corresponding to NO), the calculation result output unit 12 calculates the required amount stored in the calculation result storage unit 13. Is output and the process ends. On the other hand, if there is a first row to be calculated (corresponding to YES), the required amount calculation unit 11 extracts the first row (see step ST115).

Then, the required amount calculation unit 11 acquires a part number associated with the model number (product A) of one extracted record from the product information storage unit 31 (see step ST116).

Further, the required amount calculation unit 11 acquires configuration information from the configuration information storage unit 32 using the acquired part number as a parent part number. Then, the required amount calculation unit 11 acquires the type of component and the number of components for the specification value associated with the parent component number from the parameterized definition (see step ST117).

Subsequently, the requirement calculation unit 11 acquires configuration information from the configuration information storage unit 32 using the acquired child part number as the parent part number. Then, the required amount calculation unit 11 acquires the type of component and the number of components corresponding to the specification value associated with the parent component number from the parameterized definition. Then, the required amount calculation unit 11 multiplies the number of acquired child parts by the number of parent parts (the previously acquired child parts). The requirement calculation unit 11 repeatedly obtains the calculation result of the requirement until the child parts constituting the above processing cannot be acquired.

Next, the requirement calculation unit 11 obtains the calculation result of the requirement already stored in the calculation result storage unit 13, and obtains the calculation result of the requirement obtained in the process of step ST117. Calculate the sum of the numbers of the same part number. Then, the requirement calculation unit 11 stores the updated calculation result of the requirement in the calculation result storage unit 13 (see step ST118).

Next, the requirement calculation unit 11 deletes the record extracted as one record in the first row from the calculation target record (see step ST119). Then, the process returns to step ST114.

In this way, for some specification items for which specification values have been determined, the required amount is calculated using the specification values, and for some specification items for which specification values have not been determined, predicted values based on demand forecast information. By calculating the required amount based on the above, it is possible to suppress the occurrence of a shortage or defective inventory (excess inventory).

Also, the required amount can be efficiently calculated by determining the type of component and the number of components required according to the determined specification value based on the parameterized configuration information.

<Effect>
Below, the effect by said embodiment is illustrated. In the following, effects based on the specific configuration exemplified in the above-described embodiment will be described. However, other similar configurations exemplified in the present specification may be substituted within a range where the similar effect is generated. May be.

Specifically, the required amount calculation unit 11 calculates the required amount of parts based on the specification value for each item of the specification corresponding to the specification required in the order of the product.

The configuration information storage unit 32 stores configuration information, which is information indicating the relationship between the specification value and the type of component and the number of components required corresponding to the specification value.

The demand prediction information storage unit 42 stores a predicted value of a predetermined specification value for each specification item.

Here, the required amount calculation unit 11 calculates the required amount of parts based on the specification value while referring to the configuration information for the item of the specification to which the specification value is input. Further, the requirement calculation unit 11 calculates the component requirement based on the predicted value while referring to the configuration information for the item of the specification for which the specification value is not input.
