Description

本発明は、ＣＡＤ等で設計した設計品の推定価格や推定納期などを見積る設計品見積システムおよび設計品見積プログラムに関する。 The present invention relates to a designed product estimation system and a designed product estimation program for estimating the estimated price, estimated delivery date, etc. of a designed product designed using CAD or the like.

ＣＡＤ等で部品などの製作品（既製品ではなく、新たに製作する必要があるもの）を設計する場合、より安価な製作品を設計することが求められる。そのため従来は、設計の都度、請負会社などから見積を入手する必要が生じていた。 When designing products such as parts (not ready-made products, but items that need to be newly manufactured) using CAD or the like, it is required to design products that are cheaper. Therefore, in the past, it was necessary to obtain estimates from contracting companies each time a design was completed.

また、少ない試行回数で容易に見積結果をユーザの希望価格や希望納期の範囲内に近づけることができる、という自動見積システムが知られている（例えば、特許文献１参照。）。このシステムは、アイテム群の希望価格・納期を認識する希望価格・納期認識部と、アイテム群の価格・納期を決定するアイテム群価格・納期決定部と、アイテム群を構成する複数のアイテムのうちの少なくとも１つについての製造条件を報知する検討推奨部分認識部とを備え、見積結果を希望価格・納期に近づけるために変更を検討すべき製造条件を提示するものである。 Further, an automatic quotation system is known that can easily bring the quotation result close to the user's desired price and desired delivery date with a small number of trials (for example, see Patent Document 1). This system consists of a suggested price/delivery date recognition unit that recognizes the desired price and delivery date of an item group, an item group price/delivery determination unit that determines the price and delivery date of an item group, and a and a consideration/recommendation part recognition unit that notifies manufacturing conditions for at least one of the above, and presents manufacturing conditions that should be considered for change in order to bring the estimate closer to the desired price and delivery date.

対象ＩＤ３２２には、見積対象の設計品の識別情報が記憶され、実績ＩＤ３２３には、設計品が実際に製作等（見積もりのみを含む）されてその情報が実績データベース３１に記憶された場合に、その実績ＩＤ３１０の識別情報が記憶される。マッチ率３２４には、見積タスク３３による後述のマッチ率が記憶され、推定価格３２５には、見積タスク３３による推定価格が記憶され、推定納期３２６には、見積タスク３３による推定納期が記憶される。実際価格３２７には、設計品が実際に製作等された場合の実際価格（価格３１２１）が記憶され、実際納期３２８には、設計品が実際に製作等された場合の実際納期（納期３１２２）が記憶され、その他３２９には、後述する図５に示すような見積結果が記憶される。このような実績ＩＤ３２３と実際価格３２７と実際納期３２８は、実績データベース３１に第２の実績情報３１２が記憶された際に記憶され、その他の情報は、見積タスク３３による見積結果が出力された際に記憶される。 The object ID 322 stores the identification information of the designed product to be estimated, and the track record ID 323 stores the identification information of the designed product that is the target of the estimate, and the track record ID 323 stores the information when the designed product is actually manufactured (including only the estimate) and the information is stored in the track record database 31. Identification information of the track record ID 310 is stored. The match rate 324 stores the match rate described below based on the estimation task 33, the estimated price 325 stores the estimated price based on the estimation task 33, and the estimated delivery date 326 stores the estimated delivery date based on the estimation task 33. . The actual price 327 stores the actual price (price 3121) when the designed product is actually manufactured, and the actual delivery date 328 stores the actual delivery date (delivery date 3122) when the designed product is actually manufactured. is stored, and the other 329 stores an estimation result as shown in FIG. 5, which will be described later. Such performance ID 323, actual price 327, and actual delivery date 328 are stored when the second performance information 312 is stored in the performance database 31, and other information is stored when the estimation result by the estimation task 33 is output. is memorized.

見積タスク３３は、設計端末２から受信した設計品の見積対象設計品情報と、実績データベース３１に記憶された各第１の実績情報３１１に基づいて、見積対象設計品情報に近似する実績品を抽出し、該実績品の第２の実績情報３１２に基づいて設計品の推定価格を含む見積結果を演算するプログラム・タスクである。すなわち、設計品の形状や寸法などと近似する形状や寸法などを有する実績品を抽出し、その実績品の実際価格などに基づいて設計品の推定価格などを演算するものである。 The estimation task 33 calculates a performance product that approximates the design product information to be estimated based on the design product information to be estimated for the designed product received from the design terminal 2 and each first performance information 311 stored in the performance database 31. This is a program task that calculates the estimation result including the estimated price of the designed product based on the second track record information 312 of the track record product. In other words, a proven product having a shape, size, etc. that approximates that of the designed product is extracted, and an estimated price of the designed product is calculated based on the actual price of the proven product.

具体的には、まず、設計品の形状と寸法、材質、重量、表面処理、加工精度および特殊加工などの見積対象設計品情報と、各実績品の設計図３１１１、材質３１１２、重量３１１３、表面処理３１１４、加工精度３１１５、特殊加工３１１９などの第１の実績情報３１１とを比較し、その近似率・マッチ率が高い（所定値以上の）実績品を抽出する。ここで、見積対象設計品情報ごとに重み付けを設け、特定の見積対象設計品情報に近似する実績品を優先的に抽出するようにしてもよい。例えば、寸法と材質（設計図３１１１）を重く重み付けし、寸法と材質が近似する実績品を優先的に抽出してもよい。この重み付けは、予め設定してもよいし、見積タスク３３の起動時に設定、変更するようにしてもよい。また、抽出する実績品は、ひとつでも複数でもよい。 Specifically, first, information on the designed product to be estimated, such as the shape and dimensions, material, weight, surface treatment, processing accuracy, and special processing of the designed product, as well as the design drawing 3111, material 3112, weight 3113, and surface of each actual product. Processing 3114, machining accuracy 3115, special machining 3119, etc. are compared with first performance information 311, and performance products with high approximation rate/match rate (above a predetermined value) are extracted. Here, weighting may be provided for each piece of information on the designed product to be estimated, so that actual products that are similar to the specific information on the designed product to be estimated may be extracted preferentially. For example, dimensions and materials (design drawing 3111) may be heavily weighted, and actual products with similar dimensions and materials may be preferentially extracted. This weighting may be set in advance, or may be set or changed when the estimation task 33 is activated. Further, the number of proven products to be extracted may be one or more.

次に、抽出した実績品の価格３１２１や納期３１２２などに基づき、所定の演算式、演算方法に従って設計品の推定価格や推定納期などを演算する。この際、マッチ率を考慮して演算し、例えば、マッチ率が高い場合には、実績品の価格３１２１や納期３１２２の近似値を推定価格や推定納期とし、マッチ率が低い場合には、どの見積対象設計品情報と第１の実績情報３１１とが相違するのかなどを考慮し、価格３１２１や納期３１２２の値を加減して推定価格や推定納期を演算する。さらに、価格３１２１に実績品の価格の変動に関する情報が記憶されている場合には、これらの情報に基づいて推定価格を演算する。例えば、過去から最新に至る価格変動傾向に基づいて今回の推定価格を演算したり、今回を含む累計個数が何個になるからどのくらい安くなるかを考慮して価格傾向を演算したりする。 Next, based on the extracted price 3121, delivery date 3122, etc. of the actual product, the estimated price, estimated delivery date, etc. of the designed product are calculated according to a predetermined calculation formula and calculation method. At this time, calculations are performed taking into account the match rate. For example, if the match rate is high, approximate values of the actual product price 3121 and delivery date 3122 are used as the estimated price and estimated delivery date, and if the match rate is low, which The estimated price and estimated delivery date are calculated by adjusting the values of the price 3121 and the delivery date 3122, taking into consideration whether the estimated design product information and the first performance information 311 are different. Furthermore, if information regarding price fluctuations of actual products is stored in the price 3121, an estimated price is calculated based on this information. For example, the current estimated price is calculated based on price fluctuation trends from the past to the latest, or the price trend is calculated by considering how much the price will be because of the cumulative number of items including the current price.

また、複数の実績品を抽出した場合には、各実績品の価格３１２１や納期３１２２とそのマッチ率に基づき、所定の演算式、演算方法に従って推定価格や推定納期などを演算する。例えば、実績品Ａ、Ｂが抽出されて実績品Ａのマッチ率が実績品Ｂよりも高い場合、実績品Ａの価格３１２１を基準価格とし、実績品Ｂのマッチ率と実績品Ａとの差異などを考慮し、基準価格を加減して推定価格を演算する。 Furthermore, when a plurality of actual products are extracted, the estimated price, estimated delivery date, etc. are calculated based on the price 3121 and delivery date 3122 of each actual product and their matching rate according to a predetermined calculation formula and calculation method. For example, if track record products A and B are extracted and the match rate of track record product A is higher than track record product B, the price 3121 of track record product A is used as the standard price, and the difference between the match rate of track record product B and track record product A is set as the base price. The estimated price is calculated by adding or subtracting the standard price, taking into account such factors.

また、見積タスク３３で演算、出力する見積結果には、設計品の推奨製作者や抽出した実績品の第１の実績情報３１１を含む。すなわち、上記のようにして抽出した実績品の製作者３１２３を推奨製作者として出力するとともに、実績品の設計図３１１１や材質３１１２、重量３１１３など出力する。具体的には、図５に示すように、抽出した各実績品（候補）のマッチ率、図（設計図３１１１）、材質（材質３１１２）、重量（重量３１１３）などの情報を近似率が大きい順に一覧表にして出力する。ここで、抽出した実績品が複数ある場合、マッチ率が最も高い実績品の製作者３１２３や、特定の（指定された）第１の実績情報３１１が最も近似している（例えば、特殊加工３１１９が近似している）実績品の製作者３１２３を推奨製作者として出力する。 In addition, the estimate result calculated and output in the estimate task 33 includes the recommended manufacturer of the designed product and first track record information 311 of the extracted track record product. That is, the manufacturer 3123 of the proven product extracted as described above is output as a recommended manufacturer, and the design drawing 3111, material 3112, weight 3113, etc. of the proven product are also output. Specifically, as shown in Fig. 5, information such as the match rate, diagram (design drawing 3111), material (material 3112), weight (weight 3113), etc. of each extracted actual product (candidate) is determined based on the approximate rate. Output in a list in order. Here, if there are multiple extracted track record products, the producer 3123 of the track record product with the highest matching rate or the specific (designated) first track record information 311 is the most similar (for example, the special processing 3119 The manufacturer 3123 of the proven product (which is similar) is output as the recommended manufacturer.

このような見積タスク３３を起動する際に、入力パラメータとして設計端末２から受信される設計品の見積対象設計品情報は、設計が完了した完全な情報でなくてもよい。例えば、見積対象の製作品の設計図が製作途中・未完成であってもよく、この場合、製作途中の設計図に基づいて実績品を抽出し、その設計図３１１１や材質３１１２、重量３１１３などを出力する。これにより、製作品を独自に設計しなくても、近似する設計図などを取得することができ、実績品の設計を利用して製作品の共通化・共用化を図ることが可能となる。 When activating such an estimation task 33, the estimated designed product information of the designed product received from the design terminal 2 as an input parameter does not have to be complete information on which the design has been completed. For example, the design drawing of the product to be estimated may be in the middle of production or unfinished. In this case, actual products are extracted based on the design drawing in the middle of production, and the design drawing 3111, material 3112, weight 3113, etc. Output. As a result, it is possible to obtain an approximate design drawing without having to independently design a manufactured product, and it is possible to standardize and share manufactured products by using designs of proven products.

修正タスク３４は、見積タスク３３による推定価格と、該推定価格の設計品の実際の価格とに基づいて、見積タスク３３の演算を修正するプログラム・タスクである。すなわち、ある設計品に対して見積タスク３３で推定価格を演算した後に、この設計品に対する実際価格（見積価格を含む）が得られた場合に、推定価格と実際価格との差異などに基づいて推定価格が実際価格に近づくように、見積タスク３３の演算式、演算方法を修正するものである。具体的には、例えば、推定価格３２５が実際価格３２７に近づくように、演算式の係数や重み付けなどを変更する。 The modification task 34 is a program task that modifies the calculation of the estimation task 33 based on the estimated price by the estimation task 33 and the actual price of the designed product at the estimated price. In other words, when the actual price (including the estimated price) for a certain designed product is obtained after calculating the estimated price for this designed product in the estimation task 33, based on the difference between the estimated price and the actual price, etc. The calculation formula and calculation method of the estimation task 33 are modified so that the estimated price approaches the actual price. Specifically, for example, the coefficients and weighting of the arithmetic expression are changed so that the estimated price 325 approaches the actual price 327.

ここで、１組の推定価格と実際価格のみからではなく、複数組の推定価格と実際価格に基づいて演算式、演算方法を修正してもよい。また、修正タスク３４は、人による任意のタイミングで起動してもよいし、定期的に起動してもよいし、所定の数の実際価格３２７が記憶された際に起動してもよい。 Here, the calculation formula and calculation method may be modified based not only on one set of estimated price and actual price, but also on the basis of multiple sets of estimated price and actual price. Further, the correction task 34 may be started at an arbitrary timing by a person, may be started periodically, or may be started when a predetermined number of actual prices 327 are stored.

見積依頼タスク３５は、上記の推奨製作者に見積対象設計品情報を含む見積依頼を送信するプログラム・タスクである。すなわち、図５に示すような見積結果が設計端末２のディスプレイに表示され、設計端末２において推奨製作者に見積依頼するための所定の操作が行われると、見積対象設計品情報を含む見積依頼書を作成して、その推奨製作者のコンピュータに電子メールなどで送信するものである。 The quotation request task 35 is a program task that transmits a quotation request containing quotation target design product information to the above-mentioned recommended manufacturer. That is, when an estimate result as shown in FIG. 5 is displayed on the display of the design terminal 2, and a predetermined operation is performed on the design terminal 2 to request an estimate from a recommended manufacturer, a request for estimate including information on the designed product to be estimated is made. This involves creating a book and sending it to the recommended creator's computer via e-mail or other means.

次に、このような構成の設計品見積システム１の動作などについて、図６のタイミングチャートに従って説明する。 Next, the operation of the designed product estimation system 1 having such a configuration will be explained according to the timing chart of FIG. 6.

まず、設計者等が設計端末２を使用して設計品を設計し（ステップＳ１）、所定の操作を行うと、設計図を含む見積対象設計品情報が見積コンピュータ３に送信される（ステップＳ２）。これを受けて見積コンピュータ３において見積タスク３３が起動され（ステップＳ３）、上記のようにして見積対象設計品情報に近似する実績品が抽出されて、設計品の推定価格などが演算され、推定価格や推定納期などを含む見積結果が設計端末２に送信される（ステップＳ４）。そして、例えば、図５に示すような見積結果が設計端末２のディスプレイに表示される。 First, when a designer etc. designs a designed product using the design terminal 2 (step S1) and performs a predetermined operation, information on the designed product to be estimated including the design drawings is transmitted to the estimation computer 3 (step S2). ). In response to this, the estimation task 33 is activated in the estimation computer 3 (step S3), and as described above, actual products that approximate the information on the designed product to be estimated are extracted, and the estimated price of the designed product is calculated. The estimate result including price, estimated delivery date, etc. is transmitted to the design terminal 2 (step S4). Then, for example, an estimate result as shown in FIG. 5 is displayed on the display of the design terminal 2.

ここで、例えば、製作途中の設計図等を設計品の見積対象設計品情報として設計端末２から見積コンピュータ３に送信した場合、製作途中の設計図等に基づいて実績品が抽出され、見積結果が設計端末２に送信される。このため、設計品の設計を完成させなくても、近似する設計図などを取得することができ、製作品の共通化・共用化を図ることが可能となる。 Here, for example, if a design drawing, etc. in the middle of production is sent from the design terminal 2 to the estimation computer 3 as design product information to be estimated for the designed product, actual products will be extracted based on the design drawing, etc. in the middle of production, and the estimated result will be is sent to the design terminal 2. Therefore, even if the design of the designed product is not completed, it is possible to obtain an approximate design drawing, etc., and it is possible to standardize and share manufactured products.

また、図５の見積結果を見た設計者等が、見積依頼するための所定の操作を設計端末２で行うと（ステップＳ５）、見積コンピュータ３で見積依頼タスク３５が起動され（ステップＳ６）、見積対象設計品情報を含む見積依頼書が推奨製作者のコンピュータに送信される。そして、推奨製作者から見積コンピュータ３に見積書が送信されると、該当する設計端末２に見積書が送信される。 Further, when the designer or the like who has viewed the estimate result shown in FIG. 5 performs a predetermined operation on the design terminal 2 to request an estimate (step S5), the estimate request task 35 is started on the estimate computer 3 (step S6). , a request for quotation form including information on the designed product to be quoted is sent to the computer of the recommended manufacturer. Then, when the recommended manufacturer transmits the quotation to the quotation computer 3, the quotation is transmitted to the corresponding design terminal 2.

一方、見積コンピュータ３において、見積タスク３３による見積結果が見積データベース３２に記憶され（ステップＳ７）、その後、該設計品に関する実際価格や実際納期などが知得されると、これらが実績データベース３１と見積データベース３２とに記憶される（ステップＳ８）。また、所定のタイミングにおいて修正タスク３４が起動され（ステップＳ９）、見積タスク３３の演算式、演算方法が修正される。 On the other hand, in the estimation computer 3, the estimation results obtained by the estimation task 33 are stored in the estimation database 32 (step S7), and after that, when the actual price and actual delivery date of the designed product are learned, these are stored in the performance database 31. The estimate database 32 is stored (step S8). Further, the correction task 34 is activated at a predetermined timing (step S9), and the calculation formula and calculation method of the estimation task 33 are corrected.

以上のように、この設計品見積システム１によれば、設計品の形状と寸法など（見積対象設計品情報）と、過去の各実績品の形状と寸法など（第１の実績情報３１１）に基づいて、設計品に近似する実績品が抽出され、この実績品の価格など（第２の実績情報３１２）に基づいて設計品の推定価格など（見積結果）が自動で演算されるため、設計品の推定価格などを簡易かつ迅速に見積・入手することが可能となる。この結果、設計をしながら推定価格を入手して、より安価な製作品を適正かつ迅速に設計することなどが可能となる。また、自社の実績品に基づいて自社（同社）の設計品の推定価格などを演算するため、自社の企業文化、企業方針などを反映することが可能となる。 As described above, according to the designed product estimation system 1, the shape and dimensions of the designed product (designed product information to be estimated) and the shape and dimensions of each past track record product (first track record information 311) are used. Based on this, an actual product that approximates the designed product is extracted, and the estimated price of the designed product (estimate result) is automatically calculated based on the price of this actual product (second performance information 312). It becomes possible to estimate and obtain the estimated price of a product easily and quickly. As a result, it becomes possible to obtain estimated prices while designing, and to appropriately and quickly design cheaper products. In addition, since the estimated price of the company's designed products is calculated based on the company's actual products, it is possible to reflect the company's corporate culture, corporate policies, etc.

しかも、実績品の価格の変動に関する情報、例えば、過去から最新に至る価格変動傾向や製造個数に依存する価格傾向など、に基づいて設計品の推定価格が演算されるため、価格の変動を考慮したより適正・正確な推定価格を取得することが可能となる。 Moreover, the estimated price of the designed product is calculated based on information about price fluctuations of actual products, such as price fluctuation trends from the past to the latest, and price trends that depend on the number of manufactured units, so price fluctuations are taken into account. This makes it possible to obtain a more appropriate and accurate estimated price.

また、第１の実績情報３１１および見積対象設計品情報にそれぞれ、実績品および設計品の材質、重量、表面処理、加工精度および特殊加工などが含まれ、これらの情報が近似する実績品が抽出されて、設計品の推定価格などが演算されるため、設計品の推定価格などをより適正に見積することが可能となる。すなわち、形状と寸法のみならず、材質、重量、表面処理、加工精度および特殊加工などに基づいて、実績品が抽出されるため、設計品の推定価格などをより適正・正確に見積することが可能となる。 In addition, the first performance information 311 and the estimated design product information each include the material, weight, surface treatment, processing accuracy, special processing, etc. of the performance product and design product, and performance products with similar information are extracted. Then, the estimated price of the designed product is calculated, so it becomes possible to estimate the estimated price of the designed product more appropriately. In other words, since actual products are extracted based not only on shape and dimensions, but also on material, weight, surface treatment, processing accuracy, special processing, etc., it is possible to estimate the estimated price of designed products more appropriately and accurately. It becomes possible.

さらに、見積結果として、設計品の推定納期や推奨製作者、抽出した実績品の形状と寸法など（第１の実績情報３１１）も演算、出力されるため、設計品を製作する場合に推定される納期や、どの請負会社などに製作依頼したらよいか、過去の実績品の形状や寸法などを知得することができる。この結果、希望納期に適した設計に変更したり、適正な請負会社などに製作依頼したり、あるいは、過去の実績品との共通化などを図ることが可能となる。しかも、見積依頼タスク３５によって自動的に推奨製作者に見積依頼が送信されるため、推奨製作者からの見積を容易かつ迅速に入手することが可能となる。さらに、図５に示すように、抽出された実績品に関する情報が、近似率が大きい順に一覧表にして出力されるため、設計品に近似する実績品に関する情報を容易かつ適正に把握することができる。 Furthermore, as the estimate result, the estimated delivery date of the designed product, the recommended manufacturer, the shape and dimensions of the extracted actual product, etc. (first performance information 311) are calculated and output, so it is estimated when manufacturing the designed product. You can learn about delivery dates, which contracting company to request production from, and the shape and dimensions of past products. As a result, it becomes possible to change the design to suit the desired delivery date, request production from an appropriate contracting company, or standardize the product with past products. Moreover, since the quotation request task 35 automatically sends a quotation request to the recommended manufacturer, it is possible to easily and quickly obtain a quotation from the recommended manufacturer. Furthermore, as shown in Figure 5, the information on the extracted actual products is output in a list in descending order of approximation rate, making it possible to easily and appropriately grasp information on actual products that approximate the designed product. can.

また、見積タスク３３で演算された推定価格と、この推定価格の対象である設計品の実際の価格とに基づいて、修正タスク３４によって見積タスク３３の演算が修正される。つまり、設計品の実際価格と推定価格との差に基づいて、適正な推定価格が演算されるように見積タスク３３の演算式、演算方法が修正されるため、見積タスク３３による演算精度を高めることが可能となる。 Further, the calculation of the estimation task 33 is corrected by a correction task 34 based on the estimated price calculated by the estimation task 33 and the actual price of the designed product that is the target of this estimated price. In other words, the calculation formula and calculation method of the estimation task 33 are modified so that an appropriate estimated price is calculated based on the difference between the actual price and the estimated price of the designed product, thereby increasing the calculation accuracy of the estimation task 33. becomes possible.

（実施の形態２）
図７は、この実施の形態に係る設計品見積システムの見積コンピュータ３を示す概略構成ブロック図である。この発明の実施では、情報取得タスク（情報取得手段）３７を備える点で実施の形態１と構成が異なり、実施の形態１と同等の構成については、同一符号を付することでその説明を省略する。 (Embodiment 2)
FIG. 7 is a schematic block diagram showing the estimation computer 3 of the designed product estimation system according to this embodiment. In the implementation of this invention, the configuration differs from Embodiment 1 in that an information acquisition task (information acquisition means) 37 is provided, and the same reference numerals are given to the same configuration as Embodiment 1, and the description thereof will be omitted. do.

情報取得タスク３７は、設計図から第１の実績情報３１１または見積対象設計品情報を取得するプログラム・タスクである。すなわち、例えば、実績品または設計品が設計された紙の設計図（紙設計図）をスキャニングして得られたデジタル画像（画像設計図）などから、実績品または設計品の形状と寸法、材質、重量、表面処理、加工精度および特殊加工を含む、第１の実績情報３１１または見積対象設計品情報を取得する。この際、画像解析処理によって、画像設計図から形状や寸法、材質などの情報を抽出する。 The information acquisition task 37 is a program task that acquires the first performance information 311 or the information on the designed product to be estimated from the design drawing. In other words, for example, the shape, dimensions, and material of the actual or designed product can be determined from a digital image (image design) obtained by scanning a paper blueprint (paper blueprint) on which the actual or designed product is designed. , the first performance information 311 or information on the designed product to be estimated, including weight, surface treatment, machining accuracy, and special machining. At this time, information such as shape, dimensions, and material is extracted from the image design drawing through image analysis processing.

具体的には、例えば、図８に示すような画像設計図を情報取得対象とする場合、次のようにして第１の実績情報３１１または見積対象設計品情報を抽出する。
（ａ）太い実線から形状を抽出し、ハッチングから断面形状を抽出する。
（ｂ）寸法線と寸法補助線から寸法を抽出し、寸法公差記号（例えば、「±０．０５」）から寸法公差を抽出し、はめあい公差（例えば、「Ｈ７」）から軸や穴の寸法許容差を抽出する。
（ｃ）仕上げ記号から表面あらさを抽出し、幾何公差記号から形状精度や位置精度を抽出し、加工記号から加工方法を抽出する。
（ｄ）その他、文字解析を行い、材質、重量、表面処理、特殊加工などを抽出する。 Specifically, for example, when an image design drawing as shown in FIG. 8 is the information acquisition target, the first performance information 311 or the estimate target design product information is extracted as follows.
(a) Extract the shape from the thick solid line and extract the cross-sectional shape from the hatching.
(b) Extract dimensions from dimension lines and dimension extension lines, extract dimensional tolerances from dimension tolerance symbols (e.g. "±0.05"), and dimensions of shafts and holes from fit tolerances (e.g. "H7"). Extract tolerance.
(c) Extract surface roughness from finishing symbols, extract shape accuracy and positional accuracy from geometric tolerance symbols, and extract machining method from machining symbols.
(d) In addition, character analysis is performed to extract material, weight, surface treatment, special processing, etc.

このような情報取得タスク３７は、後述するように、見積タスク３３で見積もりを行う場合のみならず、実績データベース３１に第１の実績情報３１１を記憶する場合にも起動される。例えば、過去に設計されて紙設計図として保存されている実績品の形状や寸法などを、第１の実績情報３１１として記憶、蓄積する場合に起動される。この際、例えば、見積コンピュータ３で紙設計図をスキャニングして画像設計図を生成し、情報取得タスク３７を起動することで、この画像設計図における実績品の形状や寸法などが抽出、取得される。そして、取得された形状や寸法などを第１の実績情報３１１として実績データベース３１に記憶する。 As will be described later, such an information acquisition task 37 is activated not only when estimating in the estimation task 33 but also when storing the first performance information 311 in the performance database 31. For example, it is activated when storing and accumulating as the first performance information 311 the shape and dimensions of a past product designed and saved as a paper blueprint. At this time, for example, by scanning a paper design drawing with the estimation computer 3 to generate an image design drawing and activating the information acquisition task 37, the shape and dimensions of the actual product in this image design drawing can be extracted and acquired. Ru. The acquired shape, dimensions, etc. are then stored in the performance database 31 as the first performance information 311.

次に、この実施の形態における設計品見積システム１の動作などについて、図９のタイミングチャートに従って説明する。 Next, the operation of the designed product estimation system 1 in this embodiment will be explained according to the timing chart of FIG.

まず、設計者等が設計端末２を使用して、例えば、設計品の紙設計図をスキャニングして画像設計図を生成し（ステップＳ１１）、所定の操作を行うと、この画像設計図が見積コンピュータ３に送信される（ステップＳ１２）。これを受けて見積コンピュータ３において情報取得タスク３７が起動され（ステップＳ１３）、上記のようにして、設計品の形状や寸法、材質などの見積対象設計品情報が抽出、取得される。その後、見積タスク３３が起動され（ステップＳ３）、実施の形態１と同様な処理が行われるものである。 First, a designer or the like uses the design terminal 2 to generate an image design drawing by, for example, scanning a paper design drawing of a designed product (step S11) and performs a predetermined operation. It is transmitted to the computer 3 (step S12). In response to this, the information acquisition task 37 is activated in the estimation computer 3 (step S13), and as described above, information on the designed product to be estimated, such as the shape, dimensions, and material of the designed product, is extracted and obtained. Thereafter, the estimation task 33 is activated (step S3), and the same processing as in the first embodiment is performed.

このように、この実施の形態によれば、情報取得タスク３７によって設計図から第１の実績情報３１１または見積対象設計品情報が取得される。例えば、実績品が設計された紙設計図をスキャニングして画像設計図とし、情報取得タスク３７を起動することで、この実績品の形状や寸法などが取得され、第１の実績情報３１１として実績データベース３１に記憶、蓄積することができる。このように、実績品の紙設計図に基づく第１の実績情報３１１を容易かつ適正に記憶、蓄積することが可能となり、この結果、過去の紙設計図などを活用して十分な第１の実績情報３１１を蓄積、構築することが可能となる。 In this manner, according to this embodiment, the information acquisition task 37 acquires the first track record information 311 or the information on the designed product to be estimated from the design drawing. For example, by scanning a paper blueprint on which a track record product is designed and creating an image design drawing, and activating the information acquisition task 37, the shape and dimensions of this track record product are acquired, and the track record is obtained as the first track record information 311. It can be stored and accumulated in the database 31.
