Description

  The present invention belongs to a technical field related to a vehicle component configuration setting support system that supports setting of a component configuration of a vehicle including a plurality of vehicle types that are scheduled to be sold using a computer.

In general, when planning and selling a vehicle consisting of a plurality of vehicle types (different grades, etc.) such as automobiles, the planning department first investigates market trends and demands merchantability for the vehicle. Set the product specifications for each vehicle type obtained from This product specification includes a plurality of selection specifications selected by the purchaser of the vehicle. In addition, the planning department sets a mounting rate as to how much the target sales number of each vehicle type and each selected specification is selected. Then, the design department selects parts necessary for satisfying the product specifications of each vehicle type set by the planning department, and sets the parts configuration of all vehicle models. Conventionally, the person in charge of the design department has manually set the parts configuration. However, in recent years, the computer has supported the setting of the parts configuration so that a huge number of parts can be processed quickly and accurately. Yes. For example, Patent Document 1 discloses that a component configuration code is generated quickly and accurately by automatically generating a child code constituting the parent component from a parent code of a predetermined parent component by a computer. However, not only automatic code generation but also setting of component configuration is being performed automatically.

  By the way, when the computer sets the parts configuration of the vehicle, it is performed by using standard parts determined in advance by the design department. This standard part is usually the minimum part that can satisfy the product specifications of each vehicle type, that is, the part that has the lowest part production cost or is close to it.

  On the other hand, for example, when a standard part used for a certain vehicle type or a standard part used for a selected specification can be replaced with a standard part used for another vehicle type or another selected specification, a plurality of standard parts are used. Since the number of types of specification parts is reduced in the entire vehicle consisting of the above vehicle types, the parts management cost is reduced. As a result, in a certain vehicle model, a certain part is replaced with a component that has an extra part that is not necessary to satisfy the product specification of the vehicle model, and the part production cost is higher than before replacement. When viewed as a whole, there is a possibility that the component cost composed of the component production cost and the component management cost is reduced.

  However, the number of parts of the vehicle is enormous, and considering the replacement of parts one by one is a difficult task and takes an enormous amount of time.

  The present invention has been made in view of such a point, and the object of the present invention is to further promote the idea of setting a vehicle component configuration using a computer and to optimize the number of types of components used in the vehicle. This makes it possible to easily reduce the parts cost of the entire vehicle and to easily review the product specifications and the target sales volume from the cost aspect.

  This minimizes the parts cost of the entire vehicle that is planned for sale and provides the most favorable part configuration.

  In the invention of claim 3, in the invention of claim 2, the product specification includes a plurality of selection specifications to be selected by the purchaser of the vehicle, and the component configuration setting processing unit integrates the vehicle type or the selection specifications. In each of the cases where it is performed or not, it is configured to perform the parts type optimization process to set the parts configuration of all the vehicle types of the vehicle and calculate the parts cost of the entire vehicle in the parts configuration. It shall be.

  This makes it possible to compare the parts cost of the entire vehicle with and without the integration of the vehicle type or selection specification, and to make the vehicle type and selection specification as low as possible. It can be easily reviewed.

  According to a fourth aspect of the present invention, in the second aspect of the present invention, the computer further includes a target sales volume database for storing the target sales volume for each vehicle type. When the number of types of parts is optimized and the parts configuration of all models of the vehicle is set, and each model is sold according to the target sales number. In each case where the vehicle is not sold, it is assumed that the component cost for one vehicle of each vehicle type is calculated.

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

  FIG. 1 shows a schematic configuration of a vehicle component configuration setting support system according to an embodiment of the present invention. This vehicle component configuration setting support system is used by a person in charge of a product planning department of a company that manufactures a vehicle such as an automobile. The product planning department terminal 1 to be operated, the design department terminal 2 operated by the person in charge of the design department of the company, the product planning department terminal 1 and the design department terminal 2 and the communication network 3 (in this case, in-house And a management server 5 connected via a LAN (Local Area Network).

  The management server 5 includes a CPU that performs information processing, a storage device that stores an information processing program, a communication interface for communicating with the product planning department terminal 1 and the design department terminal 2 via the communication network, and the like. Which functions as an application server for the product planning department terminal 1 and the design department terminal 2. On the other hand, the product planning department terminal 1 and the design department terminal 2 are personal computers, and in addition to the CPU, storage device, and communication interface similar to the management server 5, a display for displaying various information, It has a pointing device such as a keyboard and a mouse as input means. Then, the product planning department terminal 1 and the design department terminal 2 and the management server 5 can perform two-way communication via the communication network 3 according to a general communication method in order to transmit and receive information. It is like that.

  The management server 5 includes a product specification database (DB) 11, a part number database 12, a part cost database 13, a target sales volume database 14, a compatibility database 15, a round-off amount database 16, and a part configuration database 17. Thus, these databases 11 to 17 can be accessed by a general method as needed during the operation.

  In the product specification database 11, product specifications for each vehicle type obtained from a merchandise requirement for a vehicle (which may be a single vehicle or a plurality of vehicles) consisting of a plurality of vehicle types scheduled to be sold. And standard parts determined in advance by the design department so as to satisfy the product specifications of each vehicle type. For example, as shown in FIG. 2, the vehicle A that is scheduled to be sold (designated by a drawing instruction number, in this embodiment, for a specific destination such as Japan, In the case of vehicles for all destinations), there are four types, A type, B type, C type and D type, and the product specifications of each type are stored. For example, in the A model, the body is the A body, the mission is MT (manual transmission), the battery is the A battery assembly, and in the B model, the body is the A body and the mission is AT (automatic transmission). The battery is a B battery assembly, and so on. This product specification includes a plurality of selection specifications to be selected by the vehicle purchaser. In the example of FIG. 2, there are four selection specifications (A radio assembly, B radio assembly, C radio assembly, and D radio assembly) that are different in the type of the radio assembly in the A vehicle type. Select one of the selection specifications (depending on the selection specification, multiple selections or none may be selected). Here, corresponding to these four selection specifications, the A vehicle type is divided into four vehicle types: A-1 vehicle type, A-2 vehicle type, A-3 vehicle type, and A-4 vehicle type. In the example of FIG. 2, standard parts (part names) predetermined for each assembly are stored as standard parts of the A battery assembly, such as an A battery and a cover. The product specification is input by the person in charge of the product planning department through the terminal 1 for product planning department, and the standard part is input by the person in charge of the design department through the terminal 2 for design department. .

  In the part number database 12, for example, as shown in FIG. 3, the part number of the standard part is stored in correspondence with the part name. As will be described later, this part number is included in the part configuration diagram together with the part name. be written. This part number is input by the person in charge of the design department through the design department terminal 2.

  The part cost database 13 stores a part production cost and a part management cost for each standard part. The part production cost decreases stepwise as the number of production increases, and the part management cost increases as the number of types of parts increases. For example, as shown in FIG. 4, in the case of a radio harness, there are four types, A harness, B harness, C harness, and D harness, corresponding to the type of radio assembly according to the selected specification. When producing more than one unit, the parts production cost is 2,450 yen, but there are four parts costs consisting of parts production costs and parts management costs. Will be 2950 yen. These parts production cost and parts management cost are input via the design department terminal 2 by the person in charge of the design department.

  The A harness, B harness, C harness, and D harness are configured as shown in FIGS. That is, the A harness 31 is a standard part for an A radio assembly in which an A coupler 42, a B coupler 43, and a D coupler 45 are provided in the middle in addition to the two connection terminals 41 and 41 at both ends. That is, the A radio assembly requires a harness provided with the A coupler 42, the B coupler 43, and the D coupler 45, and the A harness 31 is the component with the lowest component production cost for the A radio assembly. . The B harness 32 is a standard component for a B radio assembly in which a B coupler 43 and a D coupler 45 are provided in the middle in addition to the two connection terminals 41 and 41 at both ends. The C harness 33 is a standard component for a C radio assembly in which, in addition to the two connection terminals 41 and 41 at both ends, a C coupler 44 and a D coupler 45 are provided in the middle. The D harness 34 is a standard component for a D radio assembly in which only the D coupler 45 is provided in the middle in addition to the two connection terminals 41 and 41 at both ends.

  In the target sales volume database 14, for example, as shown in FIG. 6, the target sales volume is stored for each vehicle type, and the mounting rate indicating how much the selected specification is selected is stored. The target sales volume and the installation rate are input via the product planning department terminal 1 by the person in charge of the product planning department in consideration of the past sales results of similar models.

  The compatibility database 15 has compatibility indicating whether or not the standard parts can be replaced (if there are a plurality of vehicles scheduled to be sold, different standard parts may be used for different vehicles). It is remembered. For example, as shown in FIG. 7, the A harness 31 includes an A coupler 42, a B coupler 43, and a D coupler 45. Therefore, the A harness 31 is used instead of the B harness 32 and the D harness 34. It is possible to satisfy the specifications of the vehicle type and the A-4 vehicle type (circled). At this time, for example, when the A harness 31 is used instead of the B harness 32, the A coupler 42 of the A harness 31 is in an attached state, that is, in an attached state. On the other hand, since the A harness 31 does not have the C coupler 44, the A harness 31 cannot be used in place of the C harness 33 (marked with x). The B harness 32 can be used in place of the D harness 34, but cannot be used in place of the A harness 31 or the C harness 33. Furthermore, the C harness 33 can be used in place of the D harness 34, but cannot be used in place of the A harness 31 or the B harness 32. Further, the D harness 34 cannot be used in place of the A harness 31, the B harness 32, and the C harness 33. This compatibility data is input by the person in charge of the design department through the design department terminal 2.

  For example, as shown in FIG. 8, the discard database 16 includes a case where the original standard part (predetermined standard part) is replaced based on the compatibility stored in the compatibility database 15. The amount of loss due to discarding (referred to as discarding amount), that is, the increase in parts production cost due to replacement is stored. For example, when the C harness 33 is used in place of the D harness 34, the C coupler 44 is discarded, and the amount discarded is 140 yen. This round-off data is input by the person in charge of the design department via the design department terminal 2.

  The part configuration database 17 includes a part configuration diagram (see FIG. 13) of all vehicle types set by the management server 5 by performing the part type optimization process as described later, and before the part type number optimization process. A part configuration diagram (see FIG. 11) using predetermined standard parts is stored. In this part configuration diagram, the part number stored in the part number database 12 is described together with the part name.

  The management server 5 reads the information stored in the product specification database 11, the part number database 12, the part cost database 13, the target sales volume database 14, and the compatibility database 15, respectively, and based on the information, the parts of the vehicle A component configuration setting processing unit for setting the configuration is provided inside. The component configuration setting processing unit reads out predetermined standard parts satisfying the product specifications of each vehicle type from the product specification database 11 and reads out the compatibility between the standard parts from the compatibility database 15. The number of types of parts of the entire vehicle is optimized by performing the number of parts type optimization process for optimizing the number of types of parts of the entire vehicle scheduled for sale. It is configured to set the parts configuration for all models. In this embodiment, the number-of-components optimization process is a process for optimizing the number of types of components in the entire vehicle so that the component cost including the component production cost and the component management cost is minimized in the entire vehicle. At this time, information of the parts cost database 13 and the target sales volume database 14 is also used. That is, the number of parts produced is determined from the target sales volume and mounting rate of each vehicle type, and the part production cost is determined from this production number.If the number of types of parts decreases, the part management cost decreases. Since the part production cost is high by the amount of the round-off amount, the number of types is determined so that the part cost composed of the part production cost and the part management cost is minimized in the whole vehicle. For example, there are four types of radio harnesses, but when the C harness 33 is used instead of the D harness 34 and three types are used, or when the A harness 31 is used instead of the B harness 32 and three types are used. When the two are replaced to obtain two types, the component cost is calculated for all possible combinations, and the combination that minimizes the component cost is determined. Then, the component configuration is set in such a combination that minimizes the component cost.

  FIG. 9 shows a menu screen displayed on the display of the product planning department terminal 1 or the design department terminal 2. When the “target sales volume input” is selected and clicked on this menu screen, a screen for inputting the target sales volume is displayed, and the person in charge of the product planning department basically inputs the target sales volume. Similarly, when “installation rate input” is selected and clicked, a screen for inputting a mounting rate is displayed, and a person in charge of the product planning department basically inputs the mounting rate.

  Select and click “Enter part cost” on the menu screen to display the cost entry screen in the same form as in FIG. 4. Basically, the person in charge of the design department inputs the production quantity and the part production cost in correspondence. In addition, the parts management cost is input according to the number of types.

  When you select and click “Compatibility Input” on the menu screen, the compatibility input screen in the same form as in FIG. 7 is displayed for multiple types of parts, and the person in charge of the design department basically replaces each part. Enter availability.

  If you select and click “Amount Discrimination” on the menu screen, a screen for entering the amount of disposal in the same form as in FIG. 8 will be displayed for the above multiple types of parts. However, the amount to be discarded when each part is replaced is input.

  When selecting and clicking “Create component configuration diagram” on the menu screen, the management server 5 first displays a screen for inputting a drawing instruction number. When the drawing instruction number is input on this screen, the management server 5 Then, standard part configuration setting processing of the vehicle related to the drawing instruction number is performed. That is, the product specifications and standard parts of all vehicle types of the vehicle are read from the product specification database, and the component configuration of each vehicle type is set only with standard parts that are determined in advance so as to satisfy the product specifications of the vehicle type. Then, a screen as shown in FIG. 10 is displayed. In this screen, the standard parts to be used are marked with ○ for each vehicle type so that it can be seen which standard parts satisfy the product specifications. In FIG. 2, the assembly as the product specification is marked with a circle and is not attached to the standard part.

  When “Create part configuration diagram” on the screen of FIG. 10 is selected and clicked, the management server 5 displays a component configuration diagram using these predetermined standard parts as shown in FIG. In this component configuration diagram, the A harness 31 is used for the A radio assembly of the A-1 model, the B harness 32 is used for the B radio assembly of the A-2 model, and the C radio assembly of the A-3 model is used. The C harness 33 is used, and the D harness 34 is used for the D radio assembly of the A-4 vehicle type.

  On the other hand, when the “optimization” button on the screen of FIG. 10 is clicked, the management server 5 performs the above-described component type optimization process so that the number of types of parts of the entire vehicle is optimized. Set the vehicle component configuration. Then, the management server 5 first displays a screen similar to the screen of FIG. 10 as shown in FIG. Here, ◎ marks are attached so that the parts replaced from the original standard parts by the parts type optimization process can be seen. That is, through the optimization process for the number of component types, the A harness 31 is used instead of the B harness 32 for the B radio assembly of the A-2 vehicle type, and the D harness 34 is replaced for the D radio assembly of the A-4 vehicle type. Thus, the C harness 33 is used. As a result, the radio harness is optimized from four types to two types. 12 is clicked, the management server 5 generates a component configuration diagram in which the number of types of components of the entire vehicle is optimized as shown in FIG. 2 is displayed on the display. Also in this component configuration diagram, the component is surrounded by a frame so that the component replaced from the original standard component by the component type optimization process can be seen.

  When the “save” button in each screen of FIGS. 10 to 13 is clicked, the display content of the screen is stored in the component configuration database 17.

  When “optimum target sales number presentation” is selected and clicked on the menu screen of FIG. 9, the management server 5 performs optimum target sales number presentation processing. That is, the number of parts type optimization process is performed in each of the case where the target sales volume of a specific vehicle type (designated by a person in charge of the design department, etc.) stored in the target sales volume database is changed or not changed. Go to set the parts configuration for all vehicle types and calculate the part cost for one particular vehicle type in the part configuration. The target sales volume is changed by changing it at a predetermined setting interval from the set lower limit value to the upper limit value. This result is represented by a graph as shown in FIG. 14, for example, and the optimum target sales quantity with the lowest part cost for one unit is presented. As for the mounting rate, the optimal mounting rate may be presented in the same manner as the target sales volume.

  When the “cost change presentation due to change in sales volume” is selected and clicked on the menu screen, the management server 5 performs a process for presenting cost fluctuation due to change in sales volume. That is, the component configuration when the number of component types is optimized by the component type number optimization process as described above, that is, when each vehicle type is sold according to the target sales volume stored in the target sales volume database. Thus, the part cost for one vehicle type is calculated for each case where each vehicle type is sold according to its target sales volume and when it is not sold. At this time, it is calculated in advance that only a specific vehicle type is not sold according to the target sales volume, or when the specific vehicle model is not sold according to the target sales volume, the vehicle as a whole will be the target sales volume. It can be calculated by changing the sales volume of other models. In addition, the parts cost for one car model is calculated when the sales quantity of each car model increases and decreases at the same rate with respect to the target car sales quantity, and the part cost averaged for all car models is calculated. The above result is represented by a graph as shown in FIG. 15, for example. In this graph, “whole vehicle A” is the parts cost averaged for all the above-mentioned models, and “car A” is the parts cost for one car A when only the car A is not sold according to the target sales volume. Or, when the A model is not sold according to the target sales volume, if the sales volume of another predetermined model is changed so that the entire vehicle will be the target sales volume, it is equivalent to one of the A cars “Part B” is the part cost for one B model when only the B model is not sold according to the target sales quantity, or when the B model is not sold according to the target sales quantity. This is the part cost for one of the B vehicle types when the sales number of other vehicle types determined in advance is changed so that the overall sales volume will be the same. In addition, regarding the mounting rate, the part cost for one vehicle type may be calculated for each of the cases where the person in charge of the product planning department has set and the case where it has not been set ( The mounting rate is determined in advance so that when the mounting rate (that is, the number of units sold) of a specific vehicle type (for example, the A-1 vehicle type) does not match the above setting, the entire A vehicle type matches the target sales number. Other car models (for example, A-2 model) are changed).

  When the “sales promotion vehicle type presentation” on the menu screen is selected and clicked, the management server 5 performs a sales promotion vehicle type presentation process. That is, for each vehicle type, a fluctuation value (increase value) of the component production cost of the entire vehicle type due to the replacement from the original standard component by the above-described component type number optimization process is calculated. That is, for each vehicle type, the total amount of the amount of replacement stored in the above-mentioned amount-of-reduction database for the replaced parts is totaled to calculate the total amount. Then, for example, as shown in FIG. 16, the total amount and the sales promotion priority of each vehicle type are displayed. That is, it is assumed that the priority of sales promotion is higher in order from the vehicle model with the smallest total amount (in FIG. 16, the lower the priority number, the higher the priority). When the target part is input, for example, as shown in FIG. 17, only the input target part is displayed, and the sales promotion priority based on the amount is displayed.

  When the “model review presentation” on the menu screen is selected and clicked, the management server 5 performs a model review presentation process. In other words, in each case where the vehicle types are integrated or discontinued (all combinations of patterns are created) and each case is not performed, the component type optimization process is performed to set the component configurations for all vehicle types and Calculate the parts cost for the entire vehicle. Then, for each of the above patterns, it is calculated how much the parts cost of the vehicle as a whole is reduced compared to the case where the vehicle type is not integrated and decommissioned. For example, as shown in FIG. The winning model) and the vehicle model integration priority are displayed. That is, it is assumed that the vehicle type integration priority is higher in order from the pattern with the largest decrease amount (in FIG. 18, the lower the priority number, the higher the priority).

  When “selection specification review presentation” on the menu screen is selected and clicked, the management server 5 performs a selection specification review presentation process. That is, as in the case of the above-described vehicle type review and presentation processing, the number of parts types optimization processing is performed for each of the vehicle types when the selection specifications are consolidated or created (all combinations of patterns are created) and when each is not performed. A part configuration is set, and a part cost of the entire vehicle in the part configuration is calculated. Then, how much the parts cost of the entire vehicle is reduced compared to the case where the selection specifications are not integrated or abolished is calculated, for example, as shown in FIG. 19, the reduction amount (per one unit) And the selected specification integration priority. That is, it is assumed that the selection specification integration priority is higher in order from the pattern with the largest reduction amount (in FIG. 19, the lower the priority number, the higher the priority).

  Here, a specific processing operation of the management server 5 will be described based on the flowcharts of FIGS.

  First, the component type number optimization process will be described based on the flowchart of FIG.

  That is, in the first step S1, the standard part of the vehicle related to the input drawing instruction number is read from the product specification database, and in the next step S2, the compatibility between the standard parts is read from the compatibility database.

  In the next step S3, a compatible specific component group (for example, the A harness 31, B harness 32, C harness 33 and D harness 34) is extracted from the standard components, and in the next step S4, the extraction is performed. All the vehicle types of all the vehicles in which one specific part group is adopted are extracted, and in the next step S5, the target sales number and the mounting rate of all the vehicle types of all the vehicles are read from the target sales number database.

  In the next step S6, the planned production quantity of each part of the specific part group is calculated from the target sales quantity and mounting rate. In the case of the harness, for example, the A harness 31 is set to xx / month, the B harness 32 is set to yy / month, the C harness 33 is set to zz / month, and the D harness 34 is set to www / month.

  In the next step S7, all combinations of the parts generated by the replacement of the parts of the specific part group are calculated from the compatibility data. In the case of the harness described above, for example, as a first combination, the B harness 32 is replaced with the A harness 31, and the A harness 31, the C harness 33, and the D harness 34 are used, and the B harness 32 is used as the second combination. Instead of the A harness 31, the D harness 34 is replaced with the C harness 33, and the A harness 31 and the C harness 33 are used.

  In the next step S8, the planned production quantity of each part of the specific part group is calculated for each of the above combinations. That is, in the case of the harness described above, in the first combination, the planned production number of the A harness 31 is increased by the amount of the B harness 32 to be xx + yy units / month, the C harness 33 is the zz units / month, and the D harness 34 is www units / month. In the second combination, the A harness 31 is xx + yy units / month, and the C harness 33 is zz + ww units / month.

  In the next step S9, the component production cost and the component management cost are read out from the component cost database, and in the next step S10, for each combination, the number of parts to be produced and the number of component types are used for each combination. The total part cost of all parts of the combination is calculated.

  In the next step S11, the combination that minimizes the total component cost is selected. In the next step S12, the selected combination is set as the optimum component configuration of the specific component group. In the next step S13, It is determined whether or not all the specific component groups have been completed.

  When the determination in step S13 is NO, the process proceeds to step S14, another specific part group is set as a new specific part group, and the process returns to step S4. On the other hand, when the determination in step S13 is YES, the process proceeds to step S15, where all the set optimal component configurations and the standard component configurations including the remaining standard components other than the specific component group are sold together. Is set as an optimal component configuration that optimizes the number of types of components of the entire vehicle scheduled for the vehicle, that is, a component configuration that minimizes the component cost of the entire vehicle scheduled for sale, and then returns.

  Next, the optimum target sales number presentation process will be described based on the flowchart of FIG.

  That is, in the first step S21, the vehicle (drawing instruction number) and the vehicle type are input, and in the next step S22, the lower limit sales volume, the upper limit sales volume, and the interval for changing the target sales volume (referred to as Δ sales volume) are input. To do. Note that the value of the lower limit sales volume + Δ sales volume × n1 (n1: natural number) is the target sales volume stored in the target sales volume database, and the lower limit sales volume + Δ sales volume × n2 (n2: natural number, n2> The lower limit sales volume, the upper limit sales volume, and the Δ sales volume are input so that the value of n1) becomes the upper limit sales volume.

  In the next step S23, the target sales volume is set to the input lower limit sales volume. In the next step S24, the above-described number of parts type optimization process is performed. In the next step S25, the optimum sales volume is obtained from the target sales volume. The part cost for one specified vehicle type is calculated from the part configuration, and in the next step S26, it is determined whether or not the target sales number is the same as the upper limit sales number.

  When the determination in step S26 is NO, the process proceeds to step S27, where the target sales volume plus Δ sales volume is set as the new target sales volume, and the process returns to step S24. On the other hand, when the determination in step S26 is YES, the process proceeds to step S28 to calculate a part cost for each target sales unit obtained, and in the next step S29, the part cost for one unit is minimized. The target sales volume is displayed as the optimal target sales volume, and then the process returns.

  Next, the cost fluctuation presentation process due to the sales volume fluctuation will be described based on the flowchart of FIG. This process is performed after the number of component types is optimized by the component type number optimization process based on the target sales number stored in the target sales number database.

  That is, in the first step S41, the target sales volume for each vehicle type of the designated vehicle is read from the target sales volume database, and in the next step S42, the sales volume of each vehicle type is between the lower limit value and the upper limit value. By changing at a predetermined set interval, the parts cost for one car type is calculated for each car model when the car model is sold according to the target sales volume and when it is not sold. At this time, as described above, it is calculated that only a specific vehicle model is not sold according to the target sales volume, or when the specific vehicle model is not sold according to the target sales volume, the vehicle as a whole will be the target sales volume. In addition, the number of sales of other predetermined vehicle types may be changed and calculated.

  In the next step S43, the change in the part cost for one vehicle for each vehicle type is displayed in a graph, and in the next step S44, the sales number of each vehicle type increases and decreases at the same rate with respect to the target sales number. Calculate the parts cost for one car model for each car model, calculate the part cost averaged for all car models, and display the graph of the change in parts cost for one car average for all car models against the change in sales volume And then return.

  Next, the sales promotion vehicle type presentation process will be described based on the flowchart of FIG.

  That is, in the first step S51, the target vehicle (drawing instruction number) is input, and the target part is input as necessary. In the next step S52, it is determined whether or not the target part has been input. .

  When the determination in step S52 is YES, the process proceeds to step S53, where the amount of disposal of the target part is read from the disposal amount database, and in the next step S54, the priority order is determined in descending order of the amount of disposal of the target part. Turn on and display by car type, then return.

  On the other hand, when the determination in step S52 is NO, the process proceeds to step S55, where the total amount of all parts for one vehicle is summed for each vehicle type of the target vehicle to calculate the total amount, In step S56, priorities are assigned in order from the smallest total amount, and the vehicle type is displayed. Thereafter, the process returns.

  Next, the vehicle type review presentation process will be described based on the flowchart of FIG.

  That is, in the first step S61, the target vehicle is input, and in the next step S62, all patterns (including those that are not consolidated) of each vehicle type are created, and in the next step S63, all the patterns are combined. Calculate the target sales volume for each model. For example, when the B model is abolished and integrated with the A model, the target sales volume for the A model is the target sales volume for the A model stored in the target sales volume database plus the B model. .

  In the next step S64, the number of parts type optimization process is performed. In the next step S65, the part cost of the entire vehicle for each of the patterns is reduced as compared with the case where the combination of the car types is not performed. In step S66, priorities are given to the patterns in descending order of the amount of decrease, and are displayed for each pattern. Thereafter, the process returns.

  Finally, the selection specification review presentation process will be described based on the flowchart of FIG.

  That is, in the first step S71, the target vehicle and the selection specification are input, and in the next step S72, all patterns of selection specifications are integrated (including those that are not integrated), and in the next step S73, all the above patterns are created. On the other hand, the target sales volume of the selected specification based on the consolidation of the selected specification is calculated.

  In the next step S74, the number of parts type optimization process is performed. In the next step S75, the part cost of the entire vehicle is reduced for each pattern as compared with the case where the selection specifications are not integrated or abolished. In step S76, the amount of decrease is calculated and, in the next step S76, priorities are given to the patterns in descending order of the amount of decrease, and then the process returns.

  Therefore, in the above embodiment, the management server 5 optimizes the number of types of parts in the entire vehicle so that the parts cost is minimized in the entire vehicle scheduled for sale based on the compatibility between the standard parts. By performing the optimization process for the number of types of parts to be performed, the parts configuration of all types of the vehicle is set so that the number of types of parts of the entire vehicle is optimized in terms of cost. Can be easily reduced. In addition, in each of the cases where the vehicle type or the selected specification is integrated or not, the parts type optimization process is performed to set the parts configuration of all the models of the vehicle, and the parts of the entire vehicle in the parts configuration In each case where the cost is calculated or the target sales volume is changed or not changed, the parts type optimization process is performed to set the parts configuration of all the models of the vehicle and the entire vehicle in the parts configuration By calculating the parts cost, it is possible to easily review the product specifications and the target sales volume from the cost aspect.
