It is also possible to provide.

  FIG. 5 is a block diagram showing a functional configuration of the terminal devices 21 to 23 realized by executing the control program.

  Each of the terminal devices 21 to 23 of the present embodiment includes a communication unit 61, a control unit 62, a display unit 63, an operation unit 64, and a determination table storage unit 65, as shown in FIG. Yes.

  The communication unit 61 establishes communication with the management server 31 via the network 30, receives drawing data of parts stored in the drawing database 33, and sends information such as search results from the parts information database 32 to the management server 31.

  The control unit 62 causes the display unit 63 to display the drawing data acquired via the communication unit 61 as a drawing image, and causes the display unit 63 to display search result information retrieved from the component information database 32.

  The determination table storage unit 65 stores a determination table in which the relationship between the information on the component name and the component classification is associated in advance. That is, the determination table storage unit 65 stores information related to the component name and the component classification in association with each other. Further, in the determination table stored in the determination table storage unit 65, the attribute information of the component is associated with the correspondence between the information on the component name and the component classification.

  Next, the determination table stored in the determination table storage unit 65 will be described. Before that, the component classification in the component management system of this embodiment will be described with reference to FIG.

  In the component management system of the present embodiment, the component classification is hierarchically configured as a large classification, a medium classification, and a small classification as shown in FIG. The major classification is the highest classification, and here it is classified into two parts: mechanical parts and electrical parts. The middle classification is a lower classification than the major classification, and if the major classification is a machine classification, it is a fine classification such as a bearing or a shaft.

  Further, the small classification is a lower classification than the medium classification. If the medium classification is a bearing, for example, resin bearing, sintered bearing, ball bearing, H / R bearing (heat roll bearing), P / More detailed classification such as R bearing (bearing for pressure roll).

  Depending on the part of the middle class, there are parts where the minor class does not exist. It has become.

  In the component management system of the present embodiment in which the component classification has such a configuration, the determination table stored in the determination table storage unit 65 has a configuration as shown in FIG. 7, for example.

  In the determination table shown in FIG. 7, detailed information for determining a more detailed component classification from the attribute information of the component is registered together with a keyword for determining the component classification from the information regarding the component name.

  And the control part 62 extracts the information regarding a component name from the text data linked | related with the drawing of the components newly registered, or drawing image data (extraction means). Then, the control unit 62 determines the component classification to which the newly registered component belongs by referring to the determination table stored in the determination table storage unit 65 based on the extracted information on the component name (determination) means).

  Since the component classification is hierarchically configured such as major classification, middle classification, and minor classification, in the determination table shown in FIG. 7, the component classification is a plurality of conceptual components corresponding to information on the component name. It is classified.

  For example, when the determination table shown in FIG. 7 is used, if the part name information extracted from the drawing data includes the word “axis” or “BAR”, the control unit 62 determines the size of the part. It is determined that the classification is “mechanical part” and the middle classification is “axis”.

  If the detailed component classification of the component to be registered cannot be specified only by the information related to the component name, the control unit 62 extracts the attribute information of this component from the drawing data of the newly registered component. The component classification to which the newly registered component belongs is determined by referring to the determination table based on the extracted component name information and component attribute information.

  For example, when the determination table shown in FIG. 7 is used, the control unit 62 includes the word “bearing” in the part name information extracted from the drawing data, and attribute information extracted from the annotation information of the drawing data. If any of the words “poly plastic”, “POM”, or “PPS” is included, the major classification of the part is “mechanical part”, the middle classification is “bearing”, and the minor classification is “resin bearing” Is determined.

  Here, “POM” is a word indicating POM (Polyoxymethylene: polyoxymethylene or polyacetal) resin, and “PPS” is a word indicating PPS (Polyphenylenesulfide) resin, such as When the word is included in the annotation information or the like of the drawing image, it can be determined that this bearing is a resin bearing.

  The control unit 62 acquires not only text data associated with a drawing of a part to be newly registered, but also a character string image included in the drawing image data, and the acquired character string image is subjected to OCR (Optical Character Recognition: optical). By converting to text data by performing (character recognition) processing, information on the part name of the part to be newly registered and attribute information of the part are extracted.

  Note that the control unit 62 deletes a blank character included in the text data associated with the drawing of the part to be newly registered or the text data converted from the character string image included in the drawing image data, thereby newly registering. Information regarding determination of the component classification of the component to be performed and attribute information of the component may be extracted.

  Further, when extracting the attribute information of the part from the drawing image data of the part to be newly registered, the control unit 62 extracts the attribute information of the part from the annotation information expressed in the natural sentence. May be.

  The operation unit 64 inputs attribute information of a part to be newly registered and information such as a part number based on a user operation.

  Then, the control unit 62 transmits the input attribute information and component part number information to the management server 31 via the communication unit 61. Then, in the management server 31, the attribute information transmitted from the terminal devices 21 to 23 is registered in the component information database 32 by the information transmitting / receiving unit 41 as the component information.

  Next, specific operations in the component management system 10 of this embodiment will be described with reference to the drawings.

  First, the operation when the control unit 62 determines the component classification based on the determination table as shown in FIG. 7 will be described with reference to the flowchart of FIG.

  When the control unit 62 refers to the information on the part name extracted from the drawing image data and determines that “bearing” is included in the part name (step S101), the control unit 62 further includes information such as note information. It is determined whether or not any of the words “poly plastic”, “POM” or “PPS” is included (step S102).

  If any of the words “poly plastic”, “POM”, or “PPS” is included in the note information (Yes in step S102), the controller 62 determines that the part classification of this part is “resin bearing”. (Step S103).

  If any of the words “poly plastic”, “POM”, or “PPS” is not included in the note information (No in step S102), the control unit 62 further displays “ball” or “BALL” in the note information. It is determined whether any word is included (step S104).

  If the word “ball” or “BALL” is included in the note information (Yes in step S104), the control unit 62 determines that the component classification of this component is “ball bearing”. (Step S105).

  In this way, when the words included in the note information extracted from the drawing image are sequentially determined, and the words registered in the determination table cannot be confirmed, the control unit 62 determines that the component classification of this part is the “classified bearing” ] (Step S106).

  In the step S101, when “part bearing” is not included in the part name, the control unit 62 determines whether or not another keyword in the determination table is included in the part name.

  For example, when the word “BAR” or “axis” is included in the part name (Yes in step S107), the control unit 62 determines that the part classification of this part is “axis”. (Step S108).

  In this way, the control unit 62 sequentially determines whether or not the keywords registered in the determination table and the words registered in the detailed information are included in the drawing image, so that the component classification of the component to be newly registered is determined. Is identified.

  Next, an operation when registering part information of a new part by the part management system of the present embodiment will be described with reference to a specific drawing example.

  In the following description, the part information of the part of the drawing data shown in FIG. 9 will be described using the operation when newly registering in the part information database 32. Here, the case where the terminal information 21 is used to register the component information will be described.

  The drawing data shown in FIG. 9 is a drawing example of “bearing”, and various characteristic information and the like are configured as image information together with the external shape of the part.

  In the terminal device 21, when a drawing for registering part information is selected by operating the operation unit 64 (drawing selection unit), the control unit 62 transmits the selected drawing data to the drawing database 33 via the management server 31. And display it on the screen.

  FIG. 10 shows an example of a screen displayed on the display unit 63 of the terminal device 21 when the part information is registered based on the part drawing shown in FIG.

  In the screen example shown in FIG. 10, an operation screen for inputting attribute information is displayed together with a drawing image of the component for which the component information is registered.

  The user who performs the registration work first selects the component classification of the component to be registered on the operation screen. The user can select the component classification of the component to be registered from the pull-down menu. Here, a case where the component classification automatic determination button 71 is operated to perform automatic determination of the component classification will be described. .

  When the user operates the component classification automatic determination button 71, the processing as described above is performed, so that the component classification of this component is automatically determined based on the selected drawing image, as shown in FIG. The component classification is automatically set in the component classification column.

  In the screen example shown in FIG. 11, the component name is “resin bearing” because the component name is “bearing” and the word “PPS” is included in the note information.

  Therefore, “mechanical parts” is automatically set in the large classification column, “bearing” in the middle classification column, and “resin bearing” in the small classification column.

  Then, by such setting of the component classification, the operation screen for inputting attribute information is set in advance for the selected resin classification “resin bearing” as shown in FIG. The attribute item that is displayed is automatically displayed.

  Specifically, the attribute items “Part Number”, “Part Name”, “Manufacturer Name”, “Manufacturer Model Number”, “Inner Diameter” and “Outer Diameter” are set by setting the component classification “Resin Bearing”. It is displayed.

  The displayed attribute items are set for each component classification. For example, when the component classification “motor” is selected or set, the attribute items as shown in FIG. When the component classification is selected or set, the attribute items as shown in FIG. 12B are set.

  As described above, in this embodiment, the attribute items to be input for each component classification are set in advance, and the attribute items set for each component classification are displayed only by selecting or setting the component classification. , The user is prompted to enter an attribute value. As a result, according to the component management system of the present embodiment, even a person with little knowledge of the component can grasp the attribute items to be registered according to the type of the component and perform the component information registration work. It becomes possible.

  Then, the user inputs an attribute value for each displayed attribute item based on the component drawing. When inputting the attribute value, the user may input the attribute value manually by referring to the character of the part drawing, or the user selects the character string area to be input in the drawing image. Then, OCR processing may be performed on the selected character string image to convert it into text information, and the converted text information may be taken into the attribute value input field.

  Then, as a result of the operation by the user, when attribute values are input for all attribute items as shown in FIG. 13, the user clicks the registration button 72.

  Then, the attribute value input to this attribute item is transmitted to the management server 31 as the attribute information of this component and is registered in the component information database 32.

  As shown in FIG. 14, the control unit 62 deletes the blank character included in the text information when converting the character string image in the note included in the drawing data of the part to be newly registered into text information. Then, the attribute information of this part is extracted.

  For example, as shown in FIG. 14A, by deleting a space that is a blank character from the character string “manufacturing number: 1234567”, the attribute value of the attribute item “manufacturing number” is “1234567”. Judge that there is.

  Similarly, as shown in FIG. 14B, by deleting a space that is a blank character from the character string “maximum voltage: 125 V”, the attribute value of the attribute item “maximum voltage” becomes “ 125V ".

  Further, as shown in FIG. 15, when the note included in the drawing data of the part to be newly registered is composed of a natural sentence, the control unit 62 selects this part from the annotation information expressed by the natural sentence. Extract attribute information for.

  For example, as shown in FIG. 15A, by detecting the word “material” from the natural sentence “6 The material of this product is PPS”, the attribute value of the attribute item “material” is changed. It is determined that it is “PPS”.

  Similarly, as shown in FIG. 15B, by detecting the word “color number” from a natural sentence “the color number of this product is 99-AAA”, “color number” It is determined that the attribute value of the attribute item is “99-AAA”.

  Then, various attribute information is taken from the drawing image by the processing described above to generate component information, and the component information of various components is registered in the component information database 32.

  Here, when the user tries to obtain component information that matches a certain search condition, the user specifies the search condition to the management server 31 via the terminal devices 21 to 23. Then, the component search unit 42 of the management server 31 matches the search information specified by the terminal devices 21 to 23 via the information transmission / reception unit 41 from the component information stored in the component information database 32. Search for.

  Then, the component list output unit 43 outputs the list of component information searched by the component search unit 42 to the terminal device that has instructed the search among the terminal devices 21 to 23.

  For example, when the user designates a search condition that the component classification is “bearing” and the attribute item “inner diameter” is “12 mm”, the component search unit 42 selects the component classification from the component information in the component information database 32. A list of parts that match the conditions of “bearing” and the attribute item “inner diameter” of “12 mm” is extracted. Then, the parts list output unit 43 outputs the list of parts extracted by the parts search unit 42 to the terminal device instructing the search among the terminal devices 21 to 23, and is thus extracted on the screen of this terminal device. You can see a list of parts.

Different attribute information for each of a plurality of composite component classes, a plurality of parts information including common attribute information set in common for all parts regardless of the composite part classification, and a part product number are stored. Details of the component information database 32 will be described later.

  A parts database in which various attribute information of parts is registered is used by various departments in the company. Therefore, the attribute information desired to be registered for each part is different for each department.

  For example, the development and design department desires a parts database that can obtain information such as whether parts for achieving a required function already exist by classifying parts by function.

  On the other hand, procurement departments such as purchasing departments, manufacturing departments, etc. can select suppliers by using the parts database classified by material and processing method rather than functional classification of parts. I hope. This is because in procurement departments such as purchasing departments, sheet metal parts are ordered from sheet metal parts manufacturers, and resin parts are ordered from resin parts manufacturers, so what is the function of the parts? This is because it is necessary to use such materials and processing methods.

  Therefore, the required specifications differ between the parts database required in the development and design department and the parts database required in the procurement department, manufacturing department, etc., and there are cases where separate databases are constructed and operated.

  However, when trying to reduce the cost of products by reducing the cost of parts, if the parts database of the development and design department is not linked with the parts database of the procurement department, manufacturing department, etc. There is a problem that the development and design department cannot grasp where it is procured from.

  For this reason, when building a database that can be used in common by the development and design department, procurement department, manufacturing department, etc. and that can obtain the necessary information, the number of attribute items to be registered in each part There is a problem that will increase.

  In addition, when selecting parts with the desired specifications from the parts that have already been set, or when trying to reduce the unit price by integrating parts with similar specifications, the part number Part specifications must be registered.

  However, the attribute items expressing the characteristics of the part differ for each type of part. For example, motors, bearings, and resin parts have completely different attribute items for expressing the characteristics of the parts. Therefore, when the necessary attribute items can be registered for each part product number, the number of attribute items becomes enormous as the number of component types increases, making it impossible to use them practically. Therefore, there is a limitation that only common attribute information such as the weight, dimensions, ordering party, and material quality of each part can be registered.

  In order to extract and link attribute items from an enormous number of drawings, it is conceivable to classify each part. Because it is possible to determine the attribute items to be registered for each classification type if the parts are classified, it is easy to determine which attribute information is selected and registered among the attribute items described in the drawing. Because it can. However, this “classification” has been performed as “functional classification” in the design department and “material processing classification” in the procurement / manufacturing department.

  For these reasons, even if you try to build a parts database that can be used in common by procurement departments, manufacturing departments, and development and design departments and that can register the required attribute information for each part, The number of attribute items that need to be registered becomes enormous and exceeds the practically usable range, making it difficult or impossible to use.

  For this reason, this embodiment can be used in common by the development and design department and procurement / manufacturing department (environmental management department, quality department, cost management department, etc.) and must be registered for each part. An object of the present invention is to realize a component management system that can reduce the number of attribute items compared to the case where the same attribute item is set for all components.

  Next, the component management system of this embodiment will be described with reference to FIG. In the following description, only parts different from the component management system of the first embodiment described above will be described.

  The information transmission / reception unit 41 according to the present embodiment is set in a two-dimensional manner by a combination of a function classification that is a classification based on a design viewpoint and a construction method / material / shape classification that is a classification based on a procurement / manufacturing viewpoint. A selection of a composite part classification that matches a newly registered part is received from a plurality of composite part classifications.

  The information transmission / reception unit 41 according to the present embodiment is set for the selected composite part classification, and is set for each part regardless of the composite part classification, a plurality of attribute information different for each composite part classification. The part information including the common attribute information and the part part number is received.

  The component information database 32 stores component information that is received by the information transmitting / receiving unit 41 and in which different attribute information is set for each composite component classification.

  More specifically, as described above, the parts information database 32 in the parts management system 10 according to the present embodiment is a function classification that is a classification from a design viewpoint and a construction method that is a classification from a procurement / manufacturing viewpoint. Different attribute information for each of multiple composite parts classifications that are set two-dimensionally by the combination of the two classifications of material and shape classification, and common attribute information that is commonly set for all parts regardless of the composite part classification And a plurality of parts information including the part number.

  The reason why different attribute information is set for each composite component classification in the component information stored in the component information database 32 will be described.

  First, FIG. 16 shows an outline of the cooperation between departments in a general company that develops, designs, and sells products.

  Each division of product planning, development, design, procurement, manufacturing, sales, maintenance, etc. in a so-called manufacturer has two axes when classified according to the flow of business execution. One of them is the engineering axis by the departments such as planning, development design, production preparation, production technology, and the other is the departments such as procurement / purchasing, manufacturing, shipping, sales, sales planning, production planning, maintenance, etc. Is the supply chain axis.

  Each of these departments has a different classification method for classifying components when performing component management.

  Specifically, in the engineering axis departments such as planning, development design, production preparation, production technology, etc., it is necessary to manage parts by function classification, which is classification from a design viewpoint. In addition, in the supply chain axis departments such as procurement / purchasing, manufacturing, shipping, sales, sales planning, production planning, maintenance, etc., parts are managed according to the method of construction / material / shape classification, which is a classification from a procurement / manufacturing perspective. There is a need.

  Therefore, in the component management system 10 of the present embodiment, the component information is 2 by a combination of two classifications, that is, a functional classification that is a classification based on a design viewpoint and a construction method / material / shape classification that is a classification based on a procurement and manufacturing viewpoint. Different attribute information can be set for each of a plurality of composite component categories set in a dimensional matrix.

  Next, a specific example of this composite part classification will be described with reference to FIG.

  In the specific example shown in FIG. 17, the classifications of bearings, gears / gears, covers / chutes, and frames are shown as function classifications that are classifications from a design viewpoint (development / design department perspective). In the specific example shown in FIG. 17, metal cutting / grinding parts, sheet metal / press parts, powder metallurgy parts are classified as construction methods / materials / shape classifications, which are classifications from the viewpoint of procurement and manufacturing (from the viewpoint of procurement and manufacturing). Classifications such as resin injection molded parts and resin blow molded parts are shown.

  And as a composite part classification, the above two functional classifications, construction methods / materials / shape classifications are combined two-dimensionally (biaxial), such as ball bearings, cutting frames, press gears, sheet metal covers, sheet metal frames, etc. Classification is shown.

  For example, the composite part classification “ball bearing” is a part classification included in both of the functional classification “bearing” and the construction / material / shape classification “metal cutting / grinding part”.

  In the component management system 10 of this embodiment, different attribute items can be registered for each composite component classification such as “ball bearing”, “cutting frame”, and “press gear”.

  Therefore, when trying to register the part information of a new part in the part information database 32, the user (user) who wants to register the part selects one composite part classification from the plurality of composite part classifications. To do.

  For example, when the composite part classification “molded cover” is selected, a registration frame frame as shown in FIG. 18 is displayed as a registration frame frame for registering part information.

  In the registration frame frame shown in FIG. 18, since the selected composite part classification is “molded cover”, the classification name is “cover” as the function classification and “resin (injection molding)” as the method / material / shape classification. Is already registered.

  Then, in the registration frame frame of the composite part classification “molding cover” shown in FIG. 18, the items “maximum plate thickness”, “projection area”, “molding pressure”, and “mold clamping force” are attribute items. Is set.

  Therefore, as shown in FIG. 19, the user can use the registered frame number for the part number, part name, manufacturer information, weight, XYZ (vertical, horizontal, height) dimensions, maximum plate thickness, projected area, molding. Attribute information such as pressure and mold clamping force can be sequentially input and registered as part information.

  FIG. 20 shows an example of a registration frame frame displayed when “Sheet metal cover” is selected in the composite part classification shown in FIG.

  In the example shown in FIG. 20, since the selected composite part classification is “sheet metal cover”, the classification name “cover” as the function classification and “sheet metal / press” as the method / material / shape classification has already been registered. It has become.

  In the registered frame of the composite part classification “sheet metal cover” shown in FIG. 20, the attribute items are “sheet thickness”, “deployment dimension”, “preston number”, “type type (single / sequential)”. "," Number of stages ", and" Number of holes "are set.

  FIG. 21 shows an example of a registration frame frame that is displayed when “press gear” is selected in the composite part classification shown in FIG.

  In the example shown in FIG. 21, since the selected composite part classification is “press gear”, the classification name “gear” as the function classification and “sheet metal / press” as the construction method / material / shape classification has already been registered. It has become.

  In the registration frame frame of the composite part classification “press gear” shown in FIG. 21, the attribute items are “number of steps”, “number of teeth”, “outside diameter φ”, “inside diameter φ”, “tooth width”, “ The item “Tooth profile error” is set.

  FIG. 22 shows an example of component information in which different attribute information is registered for each composite component classification.

  As can be seen from FIG. 22, even if the function classification is the same, if the construction method / material / shape classification is different, different attribute items may be set, and if the construction method / material / shape classification is the same, the function classification is different. Different attribute items may be set.

  For example, even if the function classification is “Cover”, the attribute item of the part information differs depending on whether the construction method / material / shape classification is “resin (injection molding)” or “sheet metal / press”. 18, see FIG. Further, for example, even if the construction method / material / shape classification is “sheet metal / press”, the attribute item of the component information differs depending on whether the function classification is “cover” or “gear” (FIG. 20, (See FIG. 21).

  For parts that do not have or cannot be classified, such as “solenoid”, “fan motor”, and “functional members special to the company”, different attribute information can be registered for each function category. It has become.

  For example, in the case of a three-layer roll having a shaft, it is registered as a paper feed roll, and attribute information of the shaft and rubber is registered. This is because it is clear that the “paper feed roll” is stably fixed with a combination of a metal shaft and a rubber roll and a manufacturing method in a time span of 10 to 20 years.

  Moreover, when using it combining a molding resin roll with a metal shaft, it registers as an independent terminal component, respectively.

  Furthermore, in a special case such as a case where a molded resin roll is integrally formed on a metal shaft, it is possible to cope by providing a plurality of material classifications.

  For example, in a material in which EPDM rubber (ethylene / propylene / diene / rubber) is bonded and fixed around a metal shaft and urethane resin is laminated on the surface layer, this roll is a specific functional member that has been conventionally recognized, such as a charging roll. If so, it is registered as one classification by its function name, not by the category of the composite classification. And if it is a component whose function is not recognized and cannot be specified, it can be applied to a composite classification such as a rubber roll, and a method of registering a shaft material and two kinds of organic materials to be laminated as attributes is also possible. If the method, material, and shape classification are not simply rubber, but they are classified into single layer rubber and laminated rubber, they can be registered in the classification such as laminated rubber roll. In any of these classification methods, the number of attributes for classification increases with the number of material types, but it can be significantly reduced compared to the number of general functional classification attributes such as rolls. The difficulty of extracting information from drawings and the like is greatly reduced.

  In the parts management system 10 of the present embodiment, a large number of parts to be managed are classified into two categories: functional classification, which is a classification from a design viewpoint, and construction method, material, and shape classification, which is a classification from a procurement / manufacturing viewpoint. Classification is performed by composite part classification set two-dimensionally by combination. For this reason, the parts management system 10 of this embodiment can be used in common in both the development design department and the procurement / manufacturing department (environmental management department, quality department, cost management department, etc.) and unified throughout the company. It is possible to perform the managed parts.

  In the component management system 10 of the present embodiment, different component information can be registered in each component for each composite component classification. Therefore, the number of attribute items that need to be registered for each component is set. Various specifications and the like of each component can be registered in the component information while keeping the number practically usable.

  In addition, the component composition table created by the classification required for the design department in the past and utilized in the design department, and the component composition table that has been constructed and utilized for each department for each procurement and manufacturing department Since the classifications can be combined with few corrections by the composite classification, there is also an advantage that the departmental asset called the component composition table constructed for each department can be effectively utilized continuously as the company-wide asset.

  For example, FIG. 23 shows a comparative example in which attribute items are simply increased without setting different attribute items for each composite part classification.

  The comparative example shown in FIG. 23 shows a case where the number of registerable attribute items is increased regardless of the type of component. In the example shown in FIG. 23, it is difficult to understand which attribute item should be used for registering attribute information for this part because attribute items that are not necessary for the part are set. It can be seen that is difficult to use.

  Specifically, in the example shown in FIG. 23, an example of registering “resin cover” as a part is shown, and “maximum plate thickness”, “projection area”, “molding pressure” are attribute items. In this example, the attribute information is registered in the item “mold clamping force”. However, it is difficult for the user to know which attribute item the attribute information should be registered.

  On the other hand, the component management system 10 according to the present embodiment prepares a registration frame frame as shown in FIG. 18 simply by selecting the category “molded cover” as the composite component category, so that the user Can easily grasp to which attribute item the attribute information should be registered.

  And according to the parts management system 10 of this embodiment, it becomes possible to perform parts management common to all departments without individual parts management between each department, and to build a parts database unified throughout the company. Is possible. Therefore, by using the component management system 10 of the present embodiment, it is possible to effectively promote the cost reduction of the product and contribute to the reduction of the total cost.

  Specifically, by using the component management system 10 according to the present embodiment, it is possible to prevent the generation of a one-part multi-part product number in which a plurality of part numbers are set for one part, thereby achieving an appropriate part price. Realization is possible.

  In addition, according to the component management system 10 of the present embodiment, it becomes easy to compare the specification and unit price of the component, so that it is possible to find a component whose price setting is higher than usual, and it is easy to realize an appropriate component price. become.

  In addition, according to the component management system 10 of the present embodiment, components having similar specifications can be easily grasped, and the component types can be reduced by standardizing components, or components having similar attributes can be compared. Therefore, it becomes possible to perform cost-effective component selection.

  Furthermore, by using the parts management system 10 of this embodiment, it becomes possible to know what parts are purchased from what suppliers and how much, and it is easy to grasp the purchase results and the procurement status. It becomes possible to grasp.

  Although not described in the present embodiment, it is possible to link the drawing management system that manages the drawing data of the component part surface with the component management system 10 of the present embodiment. As described above, by linking the drawing management system and the component management system 10, the attribute information can be directly input from the drawing data, and the user can easily view the drawing data of the searched component.
