Note that the present invention is not limited to the embodiments.
実施の形態１．
　図１は、実施の形態１にかかる影響度計算装置を用いて、過去に開発された作成済みの設計情報の中から新たに開発する設計情報を選択する処理を説明するための図である。設計情報の一例は、論理回路である。図１では、実施の形態１のユースケースの一例を示している。 Embodiment 1 FIG.
FIG. 1 is a diagram for explaining processing for selecting design information to be newly developed from design information that has been developed in the past by using the influence degree calculation apparatus according to the first embodiment. An example of design information is a logic circuit. FIG. 1 shows an example of the use case of the first embodiment.
　電気機器に用いられるソフトウェアによる演算処理を論理回路として設計する設計者１０１は、過去に開発した電気機器の論理回路等の設計情報から、新たに開発する設計情報の仕様に近いものを選択する。電気機器の一例は、電気回路の異常事態を検出して遮断するディジタル保護リレー装置である。 The designer 101 who designs the arithmetic processing by the software used for the electric equipment as a logic circuit selects the design information that is close to the specifications of the newly developed design information from the design information of the logic circuit of the electric equipment that has been developed in the past. An example of the electric device is a digital protection relay device that detects and shuts down an abnormal state of an electric circuit.
　本実施の形態では、変更影響度計算装置である影響度計算装置１が、過去に設計されて保存されている設計情報に変更が加えられた場合に、設計情報に与える影響を計算する。影響度計算装置１は、変更点が過去の設計情報に与える影響度を定量化して表示させる。これにより、設計者１０１は、新たに開発する設計情報に近い設計情報を選択するための判断材料を得ることができる。 In the present embodiment, the impact calculation device 1 that is a change impact calculation device calculates the impact on design information when a change is made to design information that has been designed and stored in the past. The influence calculation device 1 quantifies and displays the influence that the changed point has on the past design information. Thereby, the designer 101 can obtain a judgment material for selecting design information close to newly developed design information.
　図１に示すように、影響度計算装置１の使用者である設計者１０１は、今回開発する新しい設計情報の仕様を確認する（ｓ１）。影響度計算装置１は、過去に開発した電気機器で用いられるソフトウェアの設計情報Ｐ，Ｑを格納する設計情報格納部２１を有している。設計情報Ｐ，Ｑの例は、過去に開発した電気機器に用いられるソフトウェアの論理回路である。影響度計算装置１は、設計情報Ｐ，Ｑを変更した場合に、変更箇所が設計情報Ｐ，Ｑに与える影響度を変更影響度として計算するコンピュータである。影響度計算装置１は、変更箇所が設計情報Ｐに与える影響度と、変更箇所が設計情報Ｑに与える影響度とを計算して表示し、これにより設計者１０１に設計情報Ｐ，Ｑの何れかを選択させる。本実施の形態における変更影響度は、論理回路等の設計情報Ｐ，Ｑに対し変更点が与えられた場合に変更点が設計情報Ｐ，Ｑの回路全体に与える影響度である。 As shown in FIG. 1, the designer 101 who is the user of the influence calculation device 1 confirms the specifications of the new design information to be developed this time (s1). The influence degree calculation device 1 has a design information storage unit 21 for storing design information P and Q of software used in electric devices developed in the past. Examples of the design information P and Q are software logic circuits used in electrical devices developed in the past. The influence calculation device 1 is a computer that calculates, as the change influence degree, the influence degree that the changed part has on the design information P and Q when the design information P and Q are changed. The influence degree calculation device 1 calculates and displays the influence degree that the changed part has on the design information P and the influence degree that the changed part has on the design information Q, and thereby displays to the designer 101 any of the design information P and Q. To choose. The change influence degree in the present embodiment is the influence degree that the change point has on the entire circuit of the design information P and Q when the change point is given to the design information P and Q such as the logic circuit.
　設計者１０１は、設計情報Ｐに対して変更点を指定した指示を影響度計算装置１に入力し（ｓ２）、設計情報Ｑに対して変更点を指定した影響度計算装置１に入力（ｓ３）する。変更点は、今回開発する設計情報の仕様となるように設計情報Ｐ，Ｑから変更する箇所である。設計者１０１は、２つの設計情報Ｐ，Ｑのそれぞれについて、個別に変更点を入力する。 The designer 101 inputs an instruction specifying a change point with respect to the design information P (s2) and inputs it to the influence degree calculation device 1 specifying a change point with respect to the design information Q (s3). ) The changed points are places where the design information P and Q are changed so as to be the specifications of the design information to be developed this time. The designer 101 inputs a change point individually for each of the two pieces of design information P and Q.
　影響度計算装置１は、設計者１０１によって指定された変更点に基づいて、設計情報Ｐ，Ｑ毎に変更影響度を計算し表示する（ｓ４）。図１では、設計情報Ｐの変更影響度が１０であり、設計情報Ｑの変更影響度が２０である場合を示している。 The influence degree calculation device 1 calculates and displays the change influence degree for each design information P and Q based on the change point designated by the designer 101 (s4). FIG. 1 shows a case where the change influence degree of the design information P is 10 and the change influence degree of the design information Q is 20.
　影響度計算装置１が変更影響度を表示することにより、設計者１０１は、今回開発する電気機器に近い設計情報として、変更影響度が小さい設計情報を確認する（ｓ５）。ここでは、設計情報Ｐが最も変更影響度が小さいので、設計者１０１は、設計情報Ｐを基に、今回の開発を行えばよいと判断できる。 When the influence degree calculation device 1 displays the change influence degree, the designer 101 confirms design information having a small change influence degree as design information close to the electric device to be developed this time (s5). Here, since the design information P has the smallest degree of change influence, the designer 101 can determine that the current development should be performed based on the design information P.
　図２は、実施の形態１にかかる影響度計算装置で用いられる設計情報の構成例と、設計情報に基づいた演算処理を説明するための図である。ここでは、設計情報Ｐについて説明する。設計情報Ｐには、論理回路の図面が含まれる。論理回路の図面は、１つであってもよいし複数であってもよい。図２では、論理回路３１の図面と、論理回路３２の図面とを示している。 FIG. 2 is a diagram for explaining a configuration example of design information used in the influence calculation apparatus according to the first embodiment and an arithmetic process based on the design information. Here, the design information P will be described. The design information P includes a drawing of the logic circuit. There may be one or more drawings of the logic circuit. FIG. 2 shows a drawing of the logic circuit 31 and a drawing of the logic circuit 32.
　論理回路３１の図面では、入力値を読込む入力点７１、演算部６１、演算結果を出力する出力点８１といった要素が描画され、論理回路３２の図面では、入力値を読込む入力点７２、演算部６２、演算結果を出力する出力点８２，８３といった要素が描画される。 In the drawing of the logic circuit 31, elements such as an input point 71 for reading an input value, an operation unit 61, and an output point 81 for outputting the calculation result are drawn. In the drawing of the logic circuit 32, an input point 72 for reading an input value, Elements such as the calculation unit 62 and output points 82 and 83 for outputting calculation results are drawn.
　図２の論理回路３１では、入力点７１を「Ａを読込み」、演算部６１を「演算Ｘ」、出力点８１を「Ｂに出力」として図示している。また、論理回路３２では、入力点７２を「Ｂを読込み」、演算部６２を「演算Ｙ」、出力点８２を「Ｃに出力」、出力点８３を「Ａに出力」として図示している。「Ａに出力」、「Ｂに出力」、「Ｃに出力」は、それぞれメモリ等のデータ記憶領域Ａ、データ記憶領域Ｂ、データ記憶領域Ｃに演算結果である値を書き込むことを意味し、「Ａを読込み」、「Ｂを読込み」は、それぞれデータ記憶領域Ａ、データ記憶領域Ｂから値を読込むことを意味している。 2, the input point 71 is illustrated as “read A”, the calculation unit 61 as “calculation X”, and the output point 81 as “output to B”. In the logic circuit 32, the input point 72 is illustrated as “Read B”, the calculation unit 62 as “Calculation Y”, the output point 82 as “Output to C”, and the output point 83 as “Output to A”. . “Output to A”, “Output to B”, and “Output to C” mean to write values as operation results in the data storage area A, the data storage area B, and the data storage area C such as a memory, respectively. “Read A” and “Read B” mean reading values from the data storage area A and the data storage area B, respectively.
　論理回路３１では、入力点７１が入力値を読込む処理（ｓ１１）と、演算部６１が、入力点７１への入力値を基に演算を行う処理（ｓ１２）と、出力点８１が、演算部６１による演算結果を出力する処理（ｓ１３）とが実行される。 In the logic circuit 31, the input point 71 reads the input value (s11), the calculation unit 61 performs a calculation based on the input value to the input point 71 (s12), and the output point 81 calculates The process (s13) of outputting the calculation result by the unit 61 is executed.

　論理回路３１，３２において、入力点と出力点とでＡ，Ｂといった同一の符号を含んだ表示となっている場合、出力点が行う出力の値と、入力点が行う読込みの値とは同じ値である。したがって、論理回路３２の「Ａに出力」で示される出力点８３から出力される値は、論理回路３１の「Ａを読込み」で示される入力点７１で読込まれる値と同じである。また、論理回路３１の「Ｂに出力」で示される出力点８１から出力される値は、論理回路３２の「Ｂを読込み」で示される入力点７２で読込まれる値と同じである。 In the logic circuits 31 and 32, when the input point and the output point are displayed including the same sign such as A and B, the output value performed by the output point is the same as the read value performed by the input point.

Therefore, the value output from the output point 83 indicated by “output to A” of the logic circuit 32 is the same as the value read at the input point 71 indicated by “read A” of the logic circuit 31. The value output from the output point 81 indicated by “output to B” of the logic circuit 31 is the same as the value read at the input point 72 indicated by “read B” of the logic circuit 32.
　ここでは、論理回路３１による処理が先に実行され、論理回路３２による処理が後から実行される場合を一例として説明する。論理回路３１による処理が先に実行される場合、論理回路３１は、「演算Ｘ」の演算結果をデータ記憶領域Ｂに出力し、論理回路３２は、「演算Ｘ」の演算結果をデータ記憶領域Ｂから読込む。 Here, a case where the process by the logic circuit 31 is executed first and the process by the logic circuit 32 is executed later will be described as an example.

　各論理回路３１，３２は、周期単位で実行される。ここでは、論理回路３１による処理と論理回路３２による処理とからなる一連の処理が、１周期の処理である。これにより、周期Ｎ（Ｎは自然数）における論理回路３２の「Ａに出力」で示される出力点８３から出力された値は、周期Ｎ＋１における論理回路３１の「Ａを読込み」で示される入力点７１によって読込まれ、周期Ｎ＋１において演算部６１で演算される。 The logic circuits 31 and 32 are executed in units of cycles. Here, a series of processes composed of the process by the logic circuit 31 and the process by the logic circuit 32 is one cycle of process.

　ここで、変更点格納部２２に格納される変更点情報について説明する。図６は、実施の形態１にかかる変更点情報の一例を示す図である。図６では、図５に示した論理回路３３のうち「演算Ｘ」で示される演算部６３を変更した場合の変更点情報２０１を示している。 Here, the change point information stored in the change point storage unit 22 will be described. FIG. 6 is a diagram of an example of the change point information according to the first embodiment. FIG. 6 shows change point information 201 when the calculation unit 63 indicated by “Operation X” in the logic circuit 33 shown in FIG. 5 is changed.
　変更点情報２０１は、「変更点ＩＤ」と、「設計情報ＩＤ」と、「図面ＩＤ」と、「要素ＩＤ」とが対応付けされた情報テーブルである。「変更点ＩＤ」は、変更点を一意に識別する識別情報であり、「要素ＩＤ」は、同一の「図面ＩＤ」で示される図面内で変更点の要素を一意に識別する識別情報である。 The change point information 201 is an information table in which “change point ID”, “design information ID”, “drawing ID”, and “element ID” are associated with each other.

Here, the “output point ID” of the output point 84 indicated by “output to B” is “OB”, and the “output point ID” of the output point 85 indicated by “output to E” is “OE”. Assume that the “output point ID” of the output point 86 indicated by “output to F” is “OF”.
　影響度情報２０２において「変更点ＩＤ」＝「００１」、「出力点ＩＤ」が「ＯＢ」で示される変更点について説明する。「００１」の「変更点ＩＤ」で指定された変更点は、「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘにおいて、「出力点ＩＤ」＝「ＯＢ」の出力点８４に影響を与えることを示している。すなわち、「出力点ＩＤ」が「ＯＢ」の出力点８４は、「変更点ＩＤ」＝「００１」の変更点から到達可能であることを示している。なお、「変更点ＩＤ」＝「００１」の変更点が、「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに対する変更点であり、「出力点ＩＤ」＝「ＯＢ」である出力点８４が「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに属することは、図６に示した変更点情報２０１からわかる。影響度情報２０２では、「出力点ＩＤ」＝「ＯＢ」の出力点８４は、「図面ＩＤ」＝「Ｄ１」の図面上にあり、変更影響度が「１．５０」であることを示している。 A description will be given of a change point in which “change point ID” = “001” and “output point ID” are indicated by “OB” in the impact information 202.

This corresponds to the total value of “change influence degree” of “change point ID” = “001” in FIG.
　図１０は、実施の形態１にかかる影響度情報の第４の構成例を示す図である。影響度情報２０５は、図面毎に計算された変更影響度を示す情報である。影響度情報２０５では、「設計情報ＩＤ」と、「図面ＩＤ」と、「変更影響度」とが対応付けされている。 FIG. 10 is a diagram illustrating a fourth configuration example of the influence degree information according to the first embodiment. The influence degree information 205 is information indicating a change influence degree calculated for each drawing. In the impact information 205, “design information ID”, “drawing ID”, and “change impact” are associated with each other.
　影響度情報２０５において「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに属する「図面ＩＤ」＝「Ｄ１」の図面に対する変更点は、「変更影響度」が「１．５０」であることを示している。これは、図７の「図面ＩＤ」＝「Ｄ１」の「変更影響度」に対応している。 In the influence information 205, the change point for the drawing with “drawing ID” = “D1” belonging to the design information Px with “design information ID” = “P1” is that the “change influence degree” is “1.50”. Show. This corresponds to “change influence degree” of “drawing ID” = “D1” in FIG.
　同様に、影響度情報２０５において「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに属する「図面ＩＤ」＝「Ｄ２」の図面に対する変更点は、「変更影響度」が「２．００」であることを示している。これは、図７の「図面ＩＤ」＝「Ｄ２」の「変更影響度」の合計値に対応している。 Similarly, in the influence degree information 205, the change point of the drawing with “drawing ID” = “D2” belonging to the design information Px with “design information ID” = “P1” is “2.00”. It shows that there is. This corresponds to the total value of “change influence degree” of “drawing ID” = “D2” in FIG.
　図１１は、実施の形態１にかかる影響度計算装置が作成する表示情報の一例を示す図である。図１１では、表示情報３０１を表示装置１５に表示させた場合のイメージを図示している。ここでの表示情報３０１は、図５に示した「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに対し、図６に示す「変更点ＩＤ」＝「００２」の変更点が指定された場合の表示情報である。 FIG. 11 is a diagram illustrating an example of display information created by the influence calculation apparatus according to the first embodiment. FIG. 11 illustrates an image when the display information 301 is displayed on the display device 15. The display information 301 here is a case where a change point of “change point ID” = “002” shown in FIG. 6 is designated with respect to the design information Px of “design information ID” = “P1” shown in FIG. Display information.
　表示情報３０１は、論理回路３３の構成を示す表示情報３１０と、論理回路３４の構成を示す表示情報３１１とを含んでいる。表示情報３１０内の「演算Ｘ」は、変更点として目立つように表示の態様が変更されている。また、表示情報３１０，３１１内では、図７に示した出力点の変更影響度が表示されている。 The display information 301 includes display information 310 indicating the configuration of the logic circuit 33 and display information 311 indicating the configuration of the logic circuit 34. The display mode of the “calculation X” in the display information 310 is changed so as to stand out as a change point. In the display information 310 and 311, the output point change influence degree shown in FIG. 7 is displayed.
　図１１に示すように、表示情報３１０が表示される際には、「Ｂに出力」として表示される出力点８４の横に変更影響度の「１．５０」が表示される。また、表示情報３１１が表示される際には、「Ｅに出力」として表示される出力点８５の横に変更影響度の「１．００」が表示され、「Ｆに出力」として表示される出力点８６の横に変更影響度の「１．００」が表示される。 As shown in FIG. 11, when the display information 310 is displayed, the change influence degree “1.50” is displayed beside the output point 84 displayed as “output to B”. When the display information 311 is displayed, the change influence degree “1.00” is displayed beside the output point 85 displayed as “output to E”, and is displayed as “output to F”. Next to the output point 86, the change influence degree “1.00” is displayed.
　なお、表示情報３０１は、特定の変更点、特定の「設計情報ＩＤ」に対応する設計情報、または特定の「図面ＩＤ」に対応する図面等に対して作成されてもよい。その際、表示情報３０１は、変更点、「設計情報ＩＤ」、または「図面ＩＤ」等を指定するためのボタンまたはアイコンといった部品を含んでいてもよい。これらの部品に対して設計者１０１が指示情報を入力した場合には、表示情報作成部１４は、指示情報に基づいて表示情報３０１を変更する。例えば、設計者１０１によって特定の「設計情報ＩＤ」を示すボタンが指定された場合、表示情報作成部１４は、指定された「設計情報ＩＤ」の表示情報３０１を作成する。また、表示情報作成部１４が作成する表示情報３０１は、図７から図１０に示した影響度情報２０２～２０５のような表であってもよい。 The display information 301 may be created for a specific change, design information corresponding to a specific “design information ID”, or a drawing corresponding to a specific “drawing ID”. At this time, the display information 301 may include a component such as a button or an icon for designating a changed point, “design information ID”, “drawing ID”, or the like. When the designer 101 inputs instruction information for these parts, the display information creation unit 14 changes the display information 301 based on the instruction information. For example, when a button indicating a specific “design information ID” is designated by the designer 101, the display information creation unit 14 creates display information 301 of the designated “design information ID”. Further, the display information 301 created by the display information creation unit 14 may be a table such as the degree of influence information 202 to 205 shown in FIGS.
　以下、図５に示した設計情報Ｐｘ、図６に示した変更点情報２０１、図７～図１０に示した影響度情報２０２～２０５、図１１に示した表示情報３０１を用いて、影響度計算装置１の各種処理手順を説明する。 Hereinafter, using the design information Px shown in FIG. 5, the change information 201 shown in FIG. 6, the influence information 202 to 205 shown in FIGS. 7 to 10, and the display information 301 shown in FIG. Various processing procedures of the computing device 1 will be described.
　まず、影響度計算装置１の内部処理手順について説明する。図１２は、実施の形態１にかかる影響度計算装置の動作手順の一例を示すフローチャートである。影響度計算装置１が起動すると、変更点設定部１２は、設計者１０１によって入力装置１１から入力された情報と、設計情報格納部２１に格納されている設計情報Ｐｘと、に基づいて変更点の設定処理を実行する（ステップＳＴ１１）。具体的には、変更点設定部１２は、設計者１０１によって選択された設計情報と、設計者１０１によって指定された変更点とを対応付けした変更点情報２０１を生成する。変更点設定部１２は、生成した変更点情報２０１を変更点格納部２２に格納する。設計者１０１によって指定される変更点は、複数であってもよい。この場合、変更点設定部１２は、変更点情報２０１に複数の変更点を登録する。 First, the internal processing procedure of the impact calculation device 1 will be described. FIG. 12 is a flowchart of an example of an operation procedure of the influence degree calculation apparatus according to the first embodiment. When the influence degree calculation device 1 is activated, the change point setting unit 12 changes the change point based on the information input from the input device 11 by the designer 101 and the design information Px stored in the design information storage unit 21. The setting process is executed (step ST11). Specifically, the change point setting unit 12 generates change point information 201 that associates the design information selected by the designer 101 with the change point designated by the designer 101. The change point setting unit 12 stores the generated change point information 201 in the change point storage unit 22. There may be a plurality of changes specified by the designer 101. In this case, the change point setting unit 12 registers a plurality of change points in the change point information 201.
　次いで、影響度計算部１３は、設計情報格納部２１に格納されている設計情報と、変更点格納部２２に格納された変更点情報２０１とに基づいて、変更影響度の計算処理を実行する（ステップＳＴ１２）。影響度計算部１３は、変更影響度の計算処理である影響度情報２０２～２０５を影響度格納部２３に格納する。 Next, the influence degree calculation unit 13 executes a change influence degree calculation process based on the design information stored in the design information storage unit 21 and the change point information 201 stored in the change point storage unit 22. (Step ST12). The influence degree calculation unit 13 stores the influence degree information 202 to 205, which is a change influence degree calculation process, in the influence degree storage unit 23.
　次いで、表示情報作成部１４は、設計情報格納部２１に格納されている設計情報と、変更点格納部２２に格納された変更点情報２０１と、影響度格納部２３に格納された影響度情報２０２～２０５とに基づいて、表示情報３０１の作成処理を実行する（ステップＳＴ１３）。表示情報作成部１４は、入力装置１１を介して、設計者１０１から表示情報３０１の編集指示を受付けると、編集指示に基づいて表示情報３０１を変更する。表示装置１５は、作成または変更された表示情報３０１といった全ての表示情報を表示する。これにより、設計者１０１は、表示された表示情報の中から変更影響度の値が小さい設計情報を選択することができる。 Next, the display information creation unit 14 includes design information stored in the design information storage unit 21, change point information 201 stored in the change point storage unit 22, and influence degree information stored in the influence degree storage unit 23. Based on 202 to 205, a process of creating display information 301 is executed (step ST13). When the display information creation unit 14 receives an edit instruction for the display information 301 from the designer 101 via the input device 11, the display information creation unit 14 changes the display information 301 based on the edit instruction. The display device 15 displays all display information such as the created or changed display information 301. As a result, the designer 101 can select design information having a small change influence value from the displayed display information.
　ここで、上述したステップＳＴ１２の処理について説明する。 Here, the process of step ST12 described above will be described.
＜変更影響度の計算処理＞
　図１３は、実施の形態１にかかる影響度計算装置による変更影響度の計算処理手順の一例を示すフローチャートである。 <Change impact calculation processing>
FIG. 13 is a flowchart of an example of a change influence degree calculation processing procedure performed by the influence degree calculating apparatus according to the first embodiment.
　影響度計算部１３は、設計情報Ｐｘに基づいて、変更点毎に、変更点の影響を受ける出力点を抽出する（ステップＳＴ２１）。すなわち、影響度計算部１３は、変更点を起点として、変更点から到達可能な出力点を抽出する。具体的には、影響度計算部１３は、「変更点ＩＤ」＝「００１」の変更点に対して、「出力点ＩＤ」＝「ＯＢ」で「図面ＩＤ」＝「Ｄ１」の出力点８４と、「出力点ＩＤ」＝「ＯＥ」で「図面ＩＤ」＝「Ｄ２」の出力点８５と、「出力点ＩＤ」＝「ＯＦ」で「図面ＩＤ」＝「Ｄ２」の出力点８６とを抽出する。 The influence degree calculation part 13 extracts the output point which receives the influence of a change point for every change point based on the design information Px (step ST21). That is, the influence degree calculation unit 13 extracts an output point that can be reached from the change point, starting from the change point. Specifically, the influence degree calculation unit 13 outputs the output point 84 with “output point ID” = “OB” and “drawing ID” = “D1” with respect to the change point with “change point ID” = “001”. Output point 85 of “drawing ID” = “D2” when “output point ID” = “OE”, and output point 86 of “drawing ID” = “D2” when “output point ID” = “OF”. Extract.
　影響度計算部１３は、ステップＳＴ２１で抽出した出力点毎に、変更影響度を計算する（ステップＳＴ２２）。ここで、変更影響度の計算方法の一例を説明する。 The influence degree calculation unit 13 calculates the change influence degree for each output point extracted in step ST21 (step ST22). Here, an example of the calculation method of the change influence degree will be described.
　出力点単体の変更影響度は、計算対象の出力点に対し、計算対象の出力点から次に現れる出力点までの経路上に存在する要素の数と種類に応じて変化する。このため、影響度計算部１３は、論理回路３３，３４内で計算対象の出力点である第１の出力点から次に現れる出力点である第２の出力点までの経路上に存在する要素の数と種類に基づいて、変更影響度を計算する。第１の出力点から次に現れる出力点とは、第１の出力点から他の出力点を介さず直接つながっている出力点である。影響度計算部１３は、経路上に特定の要素があるごとに、計算対象の出力点の変更影響度の初期値を特定の割合で減少させる。例えば、影響度計算部１３は、経路上に特定の要素がある場合、要素１つ毎に計算対象の出力点の変更影響度の初期値を半減させる。 変 更 The change impact level of a single output point varies depending on the number and type of elements existing on the path from the calculation target output point to the next output point for the calculation target output point. For this reason, the influence calculation unit 13 is an element existing on the path from the first output point which is the output point to be calculated in the logic circuits 33 and 34 to the second output point which is the next output point. Change impact is calculated based on the number and type of The output point that appears next from the first output point is an output point that is directly connected from the first output point without passing through another output point. The influence degree calculation unit 13 decreases the initial value of the change influence degree of the output point to be calculated at a specific ratio every time there is a specific element on the route. For example, when there is a specific element on the route, the influence degree calculation unit 13 halves the initial value of the change influence degree of the output point to be calculated for each element.
　以下、出力点の変更影響度の初期値が１．００であるとする。ここでは、経路上に、ＡＮＤ回路６４，６７といった「２入力のＡＮＤ回路」の要素がある場合に、影響度計算部１３が、初期値を１／２に減少させる場合を例に説明する。この場合、影響度計算部１３は、経路上に「２入力のＡＮＤ回路」が１つあるごとに、変更影響度を１／２に減少させる。 In the following, it is assumed that the initial value of the change degree of the output point is 1.00. Here, an example will be described in which the influence calculation unit 13 reduces the initial value to ½ when there are elements of “two-input AND circuits” such as AND circuits 64 and 67 on the path. In this case, the influence degree calculation unit 13 decreases the change influence degree to ½ every time there is one “two-input AND circuit” on the path.
　図５の論理回路３４では、「出力点ＩＤ」＝「ＯＥ」の出力点８５および「出力点ＩＤ」＝「ＯＦ」の出力点８６は、次に現れる出力点が存在しない。したがって、「出力点ＩＤ」＝「ＯＥ」の出力点８５および「出力点ＩＤ」＝「ＯＦ」の出力点８６は、変更影響度が減少せず、初期値の１．００のままとなる。 In the logic circuit 34 of FIG. 5, the output point 85 with “output point ID” = “OE” and the output point 86 with “output point ID” = “OF” do not have output points that appear next. Therefore, the output point 85 of “output point ID” = “OE” and the output point 86 of “output point ID” = “OF” do not decrease the change influence and remain at the initial value of 1.00.
　「出力点ＩＤ」＝「ＯＢ」の出力点８４については、次に現れる出力点は「出力点ＩＤ」＝「ＯＥ」の出力点８５および「出力点ＩＤ」＝「ＯＦ」の出力点８６の２つとなる。この場合、影響度計算部１３は、次に現れる出力点８５，８６のそれぞれに対して計算した変更影響度の合計を、「出力点ＩＤ」＝「ＯＢ」の出力点８４の変更影響度とする。換言すると、影響度計算部１３は、次に現れる出力点が複数の場合、次に現れる出力点毎に変更影響度を計算し、計算した変更影響度を合計する。 For the output point 84 with “output point ID” = “OB”, the next output points appear are the output point 85 with “output point ID” = “OE” and the output point 86 with “output point ID” = “OF”. There will be two. In this case, the influence degree calculation unit 13 calculates the total change influence degree calculated for each of the next output points 85 and 86 as the change influence degree of the output point 84 of “output point ID” = “OB”. To do. In other words, when there are a plurality of output points that appear next, the influence degree calculation unit 13 calculates a change influence degree for each output point that appears next, and totals the calculated change influence degrees.
　まず、計算対象の出力点が「出力点ＩＤ」＝「ＯＢ」の出力点８４であり、この出力点８４の次に現れる出力点が「出力点ＩＤ」＝「ＯＥ」の出力点８５であった場合の変更影響度の計算方法を説明する。「出力点ＩＤ」＝「ＯＢ」の出力点８４から「出力点ＩＤ」＝「ＯＥ」の出力点８５に至る経路には、経路Ｒ１と経路Ｒ２との２通りの経路が存在する。この場合、影響度計算部１３は、一例として変更影響度が大きい方の経路の変更影響度を採用する。換言すると、影響度計算部１３は、計算対象の出力点から次の１つの出力点までに複数の経路がある場合、複数の経路のうち変更影響度が最も大きくなる経路の変更影響度を、計算対象の出力点での変更影響度とする。経路Ｒ１を通る場合は「２入力のＡＮＤ回路」が存在しないので、経路Ｒ１を通る場合の変更影響度は初期値の１．００のままとなる。また、経路Ｒ２上には「２入力のＡＮＤ回路」が１つ存在するので、経路Ｒ２を通る場合の変更影響度は初期値の１．００を１／２減少させた０．５０となる。したがって、計算対象の出力点が「出力点ＩＤ」＝「ＯＢ」の出力点８４であり、この出力点８４の次に現れる出力点が「出力点ＩＤ」＝「ＯＥ」の出力点８５の場合の変更影響度は、経路Ｒ１を通る場合の１．００と、経路Ｒ２を通る場合の０．５０のうちの最大値である１．００となる。 First, the output point to be calculated is the output point 84 with “output point ID” = “OB”, and the output point that appears next to this output point 84 is the output point 85 with “output point ID” = “OE”. A method for calculating the change impact level in the case of failure is described. In the route from the output point 84 of “output point ID” = “OB” to the output point 85 of “output point ID” = “OE”, there are two routes, a route R1 and a route R2. In this case, the influence degree calculation unit 13 adopts the change influence degree of the route having the larger change influence degree as an example. In other words, when there are a plurality of routes from the output point to be calculated to the next output point, the influence degree calculation unit 13 calculates the change influence degree of the route having the largest change influence degree among the plurality of routes. Change impact level at the output point to be calculated. Since there is no “two-input AND circuit” when passing through the route R1, the change influence degree when passing through the route R1 remains at the initial value of 1.00. Further, since there is one “two-input AND circuit” on the path R2, the degree of change influence when passing through the path R2 is 0.50 obtained by reducing the initial value of 1.00 by 1/2. Therefore, the output point to be calculated is the output point 84 with “output point ID” = “OB”, and the output point that appears next to this output point 84 is the output point 85 with “output point ID” = “OE”. The change influence degree of 1.00 is 1.00 which is the maximum value of 1.00 when passing through the route R1 and 0.50 when passing through the route R2.
　次いで、計算対象の出力点が「出力点ＩＤ」＝「ＯＢ」の出力点８４であり、この出力点の次に現れる出力点が「出力点ＩＤ」＝「ＯＦ」の出力点８６であった場合の変更影響度の計算方法を説明する。「出力点ＩＤ」＝「ＯＢ」の出力点８４から「出力点ＩＤ」＝「ＯＦ」の出力点８６に至る経路には、経路Ｒ１と経路Ｒ２との２通りの経路が存在する。経路Ｒ１を通る場合は「２入力のＡＮＤ回路」が１つ存在するので、経路Ｒ１を通る場合の変更影響度は初期値の１．００を１／２減少させた０．５０となる。また、経路Ｒ２を通る場合は「２入力のＡＮＤ回路」が２つ存在するため、経路Ｒ２を通る場合の変更影響度は初期値の１．００を（１／２）×（１／２）＝１／４に減少させた０．２５となる。したがって、計算対象の出力点が「出力点ＩＤ」＝「ＯＢ」の出力点８４であり、この出力点８４の次に現れる出力点が「出力点ＩＤ」＝「ＯＦ」の出力点８６の場合の変更影響度は、経路Ｒ１を通る場合の０．５０と経路Ｒ２を通る場合の０．２５のうちの最大値である０．５０となる。 Next, the output point to be calculated is the output point 84 with “output point ID” = “OB”, and the output point that appears next to this output point is the output point 86 with “output point ID” = “OF”. A method of calculating the change impact level will be described. The route from the output point 84 of “output point ID” = “OB” to the output point 86 of “output point ID” = “OF” has two routes, a route R1 and a route R2. Since there is one “two-input AND circuit” when passing through the route R1, the change influence degree when passing through the route R1 is 0.50 obtained by reducing the initial value of 1.00 by 1/2. In addition, since there are two “two-input AND circuits” when passing through the route R2, the change influence degree when passing through the route R2 is the initial value of 1.00 (1/2) × (1/2). = 0.25 which is reduced to 1/4. Therefore, the output point to be calculated is the output point 84 with “output point ID” = “OB”, and the output point that appears next to this output point 84 is the output point 86 with “output point ID” = “OF”. The change influence degree is 0.50 which is the maximum value of 0.50 when passing through the route R1 and 0.25 when passing through the route R2.
　「出力点ＩＤ」＝「ＯＢ」の出力点８４の変更影響度は、次に現れる出力点が「出力点ＩＤ」＝「ＯＥ」の場合の変更影響度＝１．００と、次に現れる出力点が「出力点ＩＤ」＝「ＯＦ」の場合の変更影響度＝０．５０の合計となる。したがって、「出力点ＩＤ」＝「ＯＢ」の変更影響度は１．５０となる。 The change influence degree of the output point 84 of “output point ID” = “OB” is the change influence degree = 1.00 when the output point that appears next is “output point ID” = “OE”, and the output that appears next. When the point is “output point ID” = “OF”, the change influence degree is 0.50. Therefore, the change influence degree of “output point ID” = “OB” is 1.50.
　影響度計算部１３は、ステップＳＴ２２で出力点毎に計算した変更影響度に基づいて、１つの観点または様々な複数の観点で、変更影響度を計算する（ステップＳＴ２３）。影響度計算部１３は、例えば、図８に示すように「変更点ＩＤ」の単位で変更影響度を計算してもよい。ここでは、「変更点ＩＤ」＝「００１」で示される変更点に対して変更影響度を計算する場合を一例として説明する。「変更点ＩＤ」＝「００１」で指定された変更点の変更影響度は、図７の影響度情報２０２で「変更点ＩＤ」＝「００１」となっている変更影響度の合計となる。すなわち、影響度情報２０２の場合、「出力点ＩＤ」＝「ＯＢ」の変更影響度、「出力点ＩＤ」＝「ＯＥ」の変更影響度、および「出力点ＩＤ」＝「ＯＦ」の変更影響度の合計が、「変更点ＩＤ」＝「００１」で示される変更点の変更影響度となる。 The influence degree calculation unit 13 calculates the change influence degree from one viewpoint or various viewpoints based on the change influence degree calculated for each output point in step ST22 (step ST23). For example, the influence degree calculation unit 13 may calculate the change influence degree in units of “change point ID” as illustrated in FIG. 8. Here, a case where the change influence degree is calculated for the change point indicated by “change point ID” = “001” will be described as an example. The change influence degree of the change point designated by “change point ID” = “001” is the sum of the change influence degrees having “change point ID” = “001” in the influence degree information 202 of FIG. That is, in the case of the influence degree information 202, the change influence degree of “output point ID” = “OB”, the change influence degree of “output point ID” = “OE”, and the change influence of “output point ID” = “OF”. The sum of the degrees becomes the change influence degree of the change point indicated by “change point ID” = “001”.
　また、影響度計算部１３は、例えば、図９に示すように「設計情報ＩＤ」の単位で変更影響度を計算してもよい。ここでは、「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘの変更影響度を計算する場合を一例として説明する。影響度計算部１３は、「設計情報ＩＤ」＝「Ｐ１」の変更影響度を、図６の変更点情報２０１および図７の影響度情報２０２に基づいて計算する。具体的には、影響度計算部１３は、変更点情報２０１から、「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに対して指定された「変更点ＩＤ」＝「００１」の変更点を抽出する。さらに、影響度計算部１３は、抽出した変更点の影響を受ける出力点として、影響度情報２０２から「出力点ＩＤ」＝「ＯＢ」の出力点８４、「出力点ＩＤ」＝「ＯＥ」の出力点８５、および「出力点ＩＤ」＝「ＯＦ」の出力点８６を抽出する。そして、影響度計算部１３は、抽出した出力点８４～８６の変更影響度を合計することによって、「設計情報ＩＤ」＝「Ｐ１」で示される設計情報Ｐｘの変更影響度を計算する。 Further, the influence degree calculation unit 13 may calculate the change influence degree in units of “design information ID” as shown in FIG. 9, for example. Here, a case where the change influence degree of the design information Px with “design information ID” = “P1” is calculated will be described as an example. The influence degree calculation unit 13 calculates the change influence degree of “design information ID” = “P1” based on the change point information 201 in FIG. 6 and the influence degree information 202 in FIG. Specifically, the influence degree calculation unit 13 obtains a change point “change point ID” = “001” designated for the design information Px of “design information ID” = “P1” from the change point information 201. Extract. Further, the influence degree calculation unit 13 outputs “output point ID” = “OB” output point 84 and “output point ID” = “OE” from the influence degree information 202 as output points affected by the extracted change point. The output point 85 and the output point 86 of “output point ID” = “OF” are extracted. Then, the influence degree calculation unit 13 calculates the change influence degree of the design information Px represented by “design information ID” = “P1” by summing the change influence degrees of the extracted output points 84 to 86.
　また、影響度計算部１３は、例えば、図１０に示すように「図面ＩＤ」の単位で変更影響度を計算してもよい。ここでは、「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに属する「図面ＩＤ」＝「Ｄ２」の図面の変更影響度を計算する場合を一例として説明する。影響度計算部１３は、「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに属する「図面ＩＤ」＝「Ｄ２」の図面の変更影響度を、図６の変更点情報２０１および図７の影響度情報２０２に基づいて算出する。影響度計算部１３は、変更点情報２０１から、「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに対して指定された「変更点ＩＤ」＝「００１」の変更点を抽出する。さらに、影響度計算部１３は、抽出した変更点の影響を受ける出力点のうち、「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに属する「図面ＩＤ」＝「Ｄ２」の出力点を抽出する。ここでの影響度計算部１３は、「出力点ＩＤ」＝「ＯＢ」の出力点８４、「出力点ＩＤ」＝「ＯＥ」の出力点８５、および「出力点ＩＤ」＝「ＯＦ」の出力点８６のうち、「図面ＩＤ」＝「Ｄ２」に対応する、「出力点ＩＤ」＝「ＯＥ」の出力点８５、および「出力点ＩＤ」＝「ＯＦ」の出力点８６を抽出する。そして、影響度計算部１３は、抽出した出力点８５，８６の変更影響度を合計することによって、「図面ＩＤ」＝「Ｄ２」で示される図面の変更影響度を計算する。 Further, for example, the influence degree calculation unit 13 may calculate the change influence degree in units of “drawing ID” as shown in FIG. Here, a case will be described as an example in which the degree of change in the drawing of “drawing ID” = “D2” belonging to the design information Px of “design information ID” = “P1” is calculated. The influence degree calculation unit 13 determines the change influence degree of the drawing of “drawing ID” = “D2” belonging to the design information Px of “design information ID” = “P1”, the change point information 201 of FIG. 6 and the influence of FIG. Calculation is based on the degree information 202. The influence degree calculation unit 13 extracts a change point of “change point ID” = “001” designated for the design information Px of “design information ID” = “P1” from the change point information 201. Further, the influence degree calculation unit 13 extracts the output point of “drawing ID” = “D2” belonging to the design information Px of “design information ID” = “P1” among the output points affected by the extracted change point. To do. Here, the influence degree calculation unit 13 outputs “output point ID” = “OB”, output point 84, “output point ID” = “OE”, output point 85, and “output point ID” = “OF”. Out of the points 86, an output point 85 with “output point ID” = “OE” and an output point 86 with “output point ID” = “OF” corresponding to “drawing ID” = “D2” are extracted. Then, the influence degree calculation unit 13 calculates the change influence degree of the drawing indicated by “drawing ID” = “D2” by summing up the change influence degrees of the extracted output points 85 and 86.
　なお、各出力点の変更影響度を合計する際に、同一の出力点の変更影響度が複数回計上される場合が考えられる。例えば、「設計情報ＩＤ」＝「Ｐ１」の設計情報Ｐｘに対し、「変更点ＩＤ」＝「００１」だけでなく「変更点ＩＤ」＝「００Ｘ」の変更点が指定されており、さらに「変更点ＩＤ」＝「００Ｘ」で指定された変更点も「出力点ＩＤ」＝「ＯＦ」の出力点８６に影響を与える場合を例に説明する。この場合、例えば「設計情報ＩＤ」＝「Ｐ１」の変更影響度の計算に際し、単に出力点の変更影響度を合計すると「出力点ＩＤ」＝「ＯＦ」の出力点８６に関する出力影響度が２回計上される。このような場合、影響度計算部１３は、同一の出力点の変更影響度の計上は１度のみとしてもよい。 It should be noted that, when the change impact level of each output point is totaled, the change impact level of the same output point may be counted multiple times. For example, for the design information Px of “design information ID” = “P1”, not only “change point ID” = “001” but also a change point of “change point ID” = “00X” is designated. The case where the change point specified by “change point ID” = “00X” also affects the output point 86 of “output point ID” = “OF” will be described as an example. In this case, for example, when calculating the change influence degree of “design information ID” = “P1”, the output influence degree relating to the output point 86 of “output point ID” = “OF” is 2 when the change influence degree of the output points is simply summed. Counted once. In such a case, the influence degree calculation unit 13 may record the change influence degree of the same output point only once.
　また、過去に設計されて保存されている設計情報Ｐ，Ｑは、過去に開発した電気機器の設計情報に限らず、現在開発中の電気機器の設計情報であってもよい。 In addition, the design information P and Q designed and stored in the past is not limited to the design information of the electrical equipment developed in the past, but may be design information of the electrical equipment currently being developed.
　表示情報作成部１４は、変更点の影響を受ける出力点の変更影響度を論理回路上に表示することができるよう表示情報３０１を作成する。表示情報作成部１４は、表示情報３０１を作成する際に、変更点の表示の態様を変更してもよい。 The display information creation unit 14 creates the display information 301 so that the change influence level of the output point affected by the change point can be displayed on the logic circuit. When the display information creation unit 14 creates the display information 301, the display information creation unit 14 may change the display mode of the changed points.
　このように実施の形態１では、影響度計算部１３が、論理回路３３，３４に対する変更点が論理回路３３，３４内の出力点８４～８６に与える変更影響度を計算し、表示装置１５が、変更影響度を示す表示情報３０１を表示する。これにより、変更点が過去に設計された設計情報Ｐｘである論理回路３３，３４に与える影響度を定量化して表示情報３０１に表示させることができる。したがって、過去に開発された設計情報Ｐ，Ｑの中から新たに開発する設計情報の仕様に近いものを正確に特定することができる。 As described above, in the first embodiment, the influence degree calculation unit 13 calculates the change influence degree that the change points with respect to the logic circuits 33 and 34 give to the output points 84 to 86 in the logic circuits 33 and 34, and the display device 15 The display information 301 indicating the change influence degree is displayed. As a result, the degree of influence of the change point on the logic circuits 33 and 34, which is the design information Px designed in the past, can be quantified and displayed on the display information 301. Therefore, it is possible to accurately specify the design information P and Q developed in the past that is close to the specifications of the newly developed design information.

　図１４は、実施の形態２にかかる影響度計算装置で用いられる設計情報の一例を示す図である。ここでは、設計情報Ｐの一例である設計情報Ｐｙが論理回路３３，３４，３５の設計情報で構成されている場合について説明する。図１４では、設計情報Ｐｙとして、論理回路３３の図面、論理回路３４の図面、および論理回路３５の図面を示している。設計情報Ｐｙは、「設計情報ＩＤ」が「Ｐ２」であるとする。すなわち、論理回路３３～３５の図面は、「設計情報ＩＤ」が「Ｐ２」の設計情報Ｐｙに属する図面である。 FIG. 14 is a diagram of an example of design information used in the influence degree calculation apparatus according to the second embodiment. Here, a case where the design information Py, which is an example of the design information P, is composed of design information of the logic circuits 33, 34, and 35 will be described. In FIG. 14, as the design information Py, a drawing of the logic circuit 33, a drawing of the logic circuit 34, and a drawing of the logic circuit 35 are shown. In the design information Py, the “design information ID” is “P2”. That is, the drawings of the logic circuits 33 to 35 belong to the design information Py whose “design information ID” is “P2”.
　論理回路３５は、「Ｆを読込み」で示される入力点７７と、「Ｇを読込み」で示される入力点７８と、入力点７７に接続されるとともに「演算Ｚ」で示される演算部６８とを備えている。また、論理回路３５は、入力点７８および演算部６８の出力側に接続されているＡＮＤ回路６９と、ＡＮＤ回路６９の出力側に接続されている「Ａに出力」の出力点９０とを備えている。「Ｇを読込み」は、データ記憶領域Ｇから値を読込むことを意味している。 The logic circuit 35 includes an input point 77 indicated by “Read F”, an input point 78 indicated by “Read G”, and an arithmetic unit 68 connected to the input point 77 and indicated by “Operation Z”. It has.

　論理回路３５の図面は、「図面ＩＤ」が「Ｄ３」であるとする。各論理回路３３～３５は、周期単位で繰り返して実行されるループ回路である。以下では、処理の実行順序が、論理回路３５、論理回路３３、論理回路３４の順序である場合を一例として説明する。論理回路３５による処理と、論理回路３３による処理と、論理回路３４による処理とからなる一連の処理が、１周期の処理である。したがって、論理回路３５による処理と、論理回路３３による処理と、論理回路３４による処理とからなる１周期分の処理が複数回繰り返される。この場合、周期Ｎにおける論理回路３４の「Ｂを読込み」で示される入力点７４は、周期Ｎにおける論理回路３３の「Ｂに出力」で示される出力点８４に格納された値を読込むことになる。また、周期Ｎ＋１における論理回路３５の「Ｆを読込み」で示される入力点７７は、周期Ｎにおける論理回路３４の「Ｆに出力」で示される出力点８６から出力された値を読込むことになる。 Suppose that the drawing of the logic circuit 35 has a “drawing ID” of “D3”. Each of the logic circuits 33 to 35 is a loop circuit that is repeatedly executed in units of cycles. Hereinafter, a case where the processing execution order is the order of the logic circuit 35, the logic circuit 33, and the logic circuit 34 will be described as an example. A series of processes including a process performed by the logic circuit 35, a process performed by the logic circuit 33, and a process performed by the logic circuit 34 is a one-cycle process. Therefore, one cycle of processing including the processing by the logic circuit 35, the processing by the logic circuit 33, and the processing by the logic circuit 34 is repeated a plurality of times. In this case, the input point 74 indicated by “Read B” of the logic circuit 34 in the cycle N reads the value stored in the output point 84 indicated by “Output to B” of the logic circuit 33 in the cycle N. become.

Further, in the logic circuit 35, a process (s43) in which the operation unit 68 performs an operation on an input value transmitted from the input point 77, an operation result transmitted from the operation unit 68, and an input point 78. The AND circuit 69 performs a logical product operation (s44) on the incoming value. Further, the logic circuit 35 executes a process (s45) in which the output point 90 outputs the calculation result sent from the AND circuit 69.

The influence degree information 208 is information indicating a change influence degree calculated for each design information. In the impact information 208, “design information ID” and “change impact” are associated with each other.
　影響度情報２０８において「設計情報ＩＤ」＝「Ｐ２」で示される変更点は、「変更影響度」が「４．００」であることを示している。 The change point indicated by “design information ID” = “P2” in the impact information 208 indicates that the “change impact” is “4.00”.
　図１８は、実施の形態２にかかる影響度情報の第４の構成例を示す図である。影響度情報２０９は、周期毎に計算された変更影響度を示す情報である。影響度情報２０９では、「設計情報ＩＤ」と、「周期」と、「変更影響度」とが対応付けされている。 FIG. 18 is a diagram illustrating a fourth configuration example of the influence degree information according to the second embodiment.

　以下、図１４に示した設計情報Ｐｙ、図６に示した変更点情報２０１、図１５～図１８に示した影響度情報２０６～２０９、図１９に示した表示情報３０２Ａ、および図２０に示した表示情報３０２Ｂを用いて、影響度計算装置１の各種処理手順を説明する。なお、実施の形態１で説明した処理と同様の処理については、その説明を省略する。 Hereinafter, the design information Py shown in FIG. 14, the change point information 201 shown in FIG. 6, the influence information 206 to 209 shown in FIGS. 15 to 18, the display information 302A shown in FIG. 19, and the display information 302A shown in FIG. Various processing procedures of the influence calculation device 1 will be described using the display information 302B. Note that description of the same processing as that described in Embodiment 1 is omitted.
　まず、影響度計算装置１の内部処理手順について説明する。図２１は、実施の形態２にかかる影響度計算装置の動作手順の一例を示すフローチャートである。影響度計算装置１が起動すると、変更点設定部１２は、設計者１０１によって入力装置１１から入力された情報と、設計情報格納部２１に格納されている設計情報と、に基づいて変更点の設定処理を実行する（ステップＳＴ３１）。具体的には、変更点設定部１２は、変更点情報２０１を生成し、生成した変更点情報２０１を変更点格納部２２に格納する。 First, the internal processing procedure of the impact calculation device 1 will be described. FIG. 21 is a flowchart of an example of an operation procedure of the influence degree calculation apparatus according to the second embodiment. When the influence degree calculation device 1 is activated, the change point setting unit 12 is configured to change the change point based on the information input from the input device 11 by the designer 101 and the design information stored in the design information storage unit 21. A setting process is executed (step ST31). Specifically, the change point setting unit 12 generates change point information 201 and stores the generated change point information 201 in the change point storage unit 22.
　次いで、影響度計算部１３は、設計情報格納部２１に格納されている設計情報と、変更点格納部２２に格納された変更点情報２０１とに基づいて、経過時間を考慮した変更影響度の計算処理を実行する（ステップＳＴ３２）。すなわち、影響度計算部１３は、周期毎の変更影響度を計算する。影響度計算部１３は、変更影響度の計算結果である影響度情報２０６～２０９を影響度格納部２３に格納する。 Next, the influence degree calculation unit 13 calculates the change influence degree in consideration of the elapsed time based on the design information stored in the design information storage unit 21 and the change point information 201 stored in the change point storage unit 22. Calculation processing is executed (step ST32). That is, the influence degree calculation part 13 calculates the change influence degree for every period. The influence degree calculation unit 13 stores the influence degree information 206 to 209 that are the calculation results of the change influence degree in the influence degree storage unit 23.
　次いで、表示情報作成部１４は、設計情報格納部２１に格納されている設計情報と、変更点格納部２２に格納された変更点情報２０１と、影響度格納部２３に格納された影響度情報２０６～２０９とに基づいて、経過時間を考慮した表示情報３０２Ａ，３０２Ｂの作成処理を実行する（ステップＳＴ３３）。表示情報作成部１４は、入力装置１１を介して、設計者１０１から表示情報３０２Ａ，３０２Ｂの編集指示を受付けると、編集指示に基づいて表示情報３０２Ａ，３０２Ｂを変更する。 Next, the display information creation unit 14 includes design information stored in the design information storage unit 21, change point information 201 stored in the change point storage unit 22, and influence degree information stored in the influence degree storage unit 23. Based on 206 to 209, the display information 302A and 302B are created in consideration of the elapsed time (step ST33). When the display information creation unit 14 receives an edit instruction for the display information 302A and 302B from the designer 101 via the input device 11, the display information creation unit 14 changes the display information 302A and 302B based on the edit instruction.
　つぎに、上述したステップＳＴ３２の処理について説明する。 Next, the process of step ST32 described above will be described.
＜経過時間を考慮した変更影響度の計算処理＞
　図２２は、実施の形態２にかかる影響度計算装置の変更影響度の計算処理手順の一例を示すフローチャートである。 <Change impact calculation processing considering elapsed time>
FIG. 22 is a flowchart of an example of the change impact degree calculation processing procedure of the impact degree calculation apparatus according to the second embodiment.
　影響度計算部１３は、設計情報Ｐｙに基づいて、変更点毎に、変更点の影響を受ける出力点を、経過時間を考慮して抽出する（ステップＳＴ４１）。すなわち、影響度計算部１３は、変更点を起点として、変更点から到達可能な出力点を抽出する。具体的には、影響度計算部１３は、「変更点ＩＤ」＝「００２」の変更点に対する「周期１」の出力点として、「出力点ＩＤ」＝「ＯＢ」で「図面ＩＤ」＝「Ｄ１」の出力点８４と、「出力点ＩＤ」＝「ＯＥ」で「図面ＩＤ」＝「Ｄ２」の出力点８５と、「出力点ＩＤ」＝「ＯＦ」で「図面ＩＤ」＝「Ｄ２」の出力点８６とを抽出する。また、影響度計算部１３は、「変更点ＩＤ」＝「００２」の変更点に対する「周期２」の出力点として、「出力点ＩＤ」＝「ＯＡ」で「図面ＩＤ」＝「Ｄ３」の出力点９０を抽出する。 The influence degree calculation unit 13 extracts, for each change point, an output point affected by the change point in consideration of the elapsed time based on the design information Py (step ST41). That is, the influence degree calculation unit 13 extracts an output point that can be reached from the change point, starting from the change point. Specifically, the influence degree calculation unit 13 sets “output point ID” = “OB” and “drawing ID” = “as the output point of“ cycle 1 ”with respect to the change point of“ change point ID ”=“ 002 ”. Output point 84 of “D1”, output point 85 of “drawing ID” = “D2” when “output point ID” = “OE”, and “drawing ID” = “D2” when “output point ID” = “OF”. Are extracted. Further, the influence degree calculation unit 13 sets “output point ID” = “OA” and “drawing ID” = “D3” as an output point of “cycle 2” with respect to the change point of “change point ID” = “002”. An output point 90 is extracted.
　次いで、影響度計算部１３は、ステップＳＴ４１で抽出した出力点毎に、経過時間を考慮した変更影響度を計算する（ステップＳＴ４２）。ステップＳＴ４２における出力点毎の変更影響度の計算方法は、実施の形態１の図１３で説明したステップＳＴ２２での計算方法と同様である。ここでは、「出力点ＩＤ」＝「ＯＦ」の出力点８６、および新たに変更影響度の計算対象となった「出力点ＩＤ」＝「ＯＡ」の出力点９０に対する変更影響度の計算方法の一例を説明する。 Next, the impact calculation unit 13 calculates the change impact considering the elapsed time for each output point extracted in step ST41 (step ST42). The calculation method of the change influence degree for each output point in step ST42 is the same as the calculation method in step ST22 described in FIG. 13 of the first embodiment. Here, the calculation method of the change influence degree with respect to the output point 86 of “output point ID” = “OF” and the output point 90 of “output point ID” = “OA” which has been newly calculated as the change influence degree. An example will be described.
　「出力点ＩＤ」＝「ＯＦ」の出力点８６については、次に現れる出力点は、周期を跨いだ「出力点ＩＤ」＝「ＯＡ」の出力点９０の１つとなる。この経路上には「２入力のＡＮＤ回路」が１つ存在するので、次に現れる出力点９０に対する変更影響度は初期値の１．００を１／２減少させた０．５０となる。したがって、「出力点ＩＤ」＝「ＯＦ」の出力点８６の変更影響度は０．５０である。 For the output point 86 with “output point ID” = “OF”, the output point that appears next is one of the output points 90 with “output point ID” = “OA” across the period. Since there is one “two-input AND circuit” on this path, the degree of change influence on the output point 90 that appears next is 0.50, which is a ½ reduction of the initial value of 1.00. Therefore, the change influence degree of the output point 86 of “output point ID” = “OF” is 0.50.
　「出力点ＩＤ」＝「ＯＡ」の出力点９０については、次に現れる出力点は、「出力点ＩＤ」＝「ＯＢ」の出力点８４の１つとなる。この経路上には「２入力のＡＮＤ回路」が存在しないので、次に現れる出力点８４に対する変更影響度は初期値の１．００のままとなる。したがって、「出力点ＩＤ」＝「ＯＡ」の出力点９０の変更影響度は１．００である。 For the output point 90 with “output point ID” = “OA”, the output point that appears next is one of the output points 84 with “output point ID” = “OB”. Since there is no “two-input AND circuit” on this path, the change influence on the output point 84 that appears next remains the initial value of 1.00. Therefore, the change influence degree of the output point 90 with “output point ID” = “OA” is 1.00.
　影響度計算部１３は、ステップＳＴ４２で出力点毎に計算した経過時間を考慮した変更影響度に基づいて、１つの観点または様々な複数の観点で変更影響度を計算する（ステップＳＴ４３）。影響度計算部１３は、例えば、図１６に示すように「変更点ＩＤ」の単位で変更影響度を計算してもよい。ここでは、「変更点ＩＤ」＝「００２」で示される変更点に対して変更影響度を計算する場合を一例として説明する。「変更点ＩＤ」＝「００２」で指定された変更点の変更影響度は、図１５の影響度情報２０６で「変更点ＩＤ」＝「００２」となっている「出力点ＩＤ」の出力点の変更影響度の合計となる。すなわち、影響度情報２０６の場合、「出力点ＩＤ」＝「ＯＢ」の変更影響度、「出力点ＩＤ」＝「ＯＥ」の変更影響度、および「出力点ＩＤ」＝「ＯＦ」の変更影響度、「出力点ＩＤ」＝「ＯＡ」の変更影響度の合計が、「変更点ＩＤ」＝「００２」で示される変更点の変更影響度となる。 The influence degree calculation unit 13 calculates the change influence degree from one viewpoint or various viewpoints based on the change influence degree in consideration of the elapsed time calculated for each output point in step ST42 (step ST43). For example, the influence degree calculation unit 13 may calculate the change influence degree in units of “change point ID” as illustrated in FIG. 16. Here, a case where a change influence degree is calculated for a change point indicated by “change point ID” = “002” will be described as an example. The change influence degree of the change point designated by “change point ID” = “002” is the output point of “output point ID” in which “change point ID” = “002” in the influence degree information 206 of FIG. The total change impact level. That is, in the case of the influence level information 206, the change influence degree of “output point ID” = “OB”, the change influence degree of “output point ID” = “OE”, and the change influence degree of “output point ID” = “OF”. The total change influence degree of “output point ID” = “OA” is the change influence degree of the change point indicated by “change point ID” = “002”.
　また、影響度計算部１３は、例えば、図１７に示すように「設計情報ＩＤ」の単位で変更影響度を計算してもよい。ここでは、「設計情報ＩＤ」＝「Ｐ２」の設計情報Ｐｙの変更影響度を計算する場合を一例として説明する。影響度計算部１３は、「設計情報ＩＤ」＝「Ｐ２」の変更影響度を、変更点情報２０１および影響度情報２０６に基づいて計算する。 Further, the influence degree calculation unit 13 may calculate the change influence degree in units of “design information ID” as shown in FIG. 17, for example. Here, a case where the change influence degree of the design information Py with “design information ID” = “P2” is calculated will be described as an example. The influence degree calculation unit 13 calculates the change influence degree of “design information ID” = “P2” based on the change point information 201 and the influence degree information 206.
　また、影響度計算部１３は、例えば、図１８に示すように「周期」の単位で変更影響度を計算してもよい。ここでは、「設計情報ＩＤ」＝「Ｐ２」の「周期１」における変更影響度を計算する場合を一例として説明する。影響度計算部１３は、「設計情報ＩＤ」＝「Ｐ２」の「周期１」における変更影響度を、変更点情報２０１および影響度情報２０６に基づいて計算する。具体的には、影響度計算部１３は、変更点情報２０１から、「設計情報ＩＤ」＝「Ｐ２」の設計情報Ｐｙに対して指定された「変更点ＩＤ」＝「００２」の変更点を抽出する。さらに、影響度計算部１３は、抽出した変更点のうち「周期１」で影響を受ける出力点として、影響度情報２０６から「出力点ＩＤ」＝「ＯＢ」の出力点８４、「出力点ＩＤ」＝「ＯＥ」の出力点８５、および「出力点ＩＤ」＝「ＯＦ」の出力点８６を抽出する。そして、影響度計算部１３は、抽出した出力点８４～８６の変更影響度を合計することによって、「設計情報ＩＤ」＝「Ｐ２」で示される設計情報Ｐｙの「周期１」における変更影響度を計算する。 Further, for example, the influence degree calculation unit 13 may calculate the change influence degree in units of “cycle” as shown in FIG. Here, a case where the change influence degree in “cycle 1” of “design information ID” = “P2” is calculated will be described as an example. The influence degree calculation unit 13 calculates the change influence degree in “cycle 1” of “design information ID” = “P2” based on the change point information 201 and the influence degree information 206. Specifically, the influence degree calculation unit 13 obtains the change point “change point ID” = “002” specified for the design information Py of “design information ID” = “P2” from the change point information 201. Extract. Furthermore, the influence degree calculation unit 13 outputs the output point 84 of “output point ID” = “OB” from the influence degree information 206 as the output point affected by “cycle 1” among the extracted change points, “output point ID”. "=" OE "output point 85 and" output point ID "=" OF "output point 86 are extracted. Then, the influence degree calculation unit 13 adds the change influence degrees of the extracted output points 84 to 86, thereby changing the change influence degree in the “cycle 1” of the design information Py indicated by “design information ID” = “P2”. Calculate
　なお、論理回路３３～３５上のある要素を変更することによって、この変更した要素の出力を使用する他の要素に対して時間差で影響を与える場合も考えられる。例えば、「演算Ｙ」が１周期後に後続の要素に影響を与える場合を例に説明する。この例の場合、例えば、「変更点ＩＤ」＝「００２」の変更点が「周期１」の時点で実行されるとすると、影響度計算部１３は、図１５に示す周期を、「出力点ＩＤ」＝「ＯＢ」の出力点８４に対して「周期」＝「１」、「出力点ＩＤ」＝「ＯＥ」の出力点８５に対して「周期」＝「２」のように計算してもよい。「出力点ＩＤ」＝「ＯＥ」の出力点８５が「周期」＝「２」と計算されるのは、「演算Ｙ」が１周期後に後続の要素に影響を与えるので、出力点８５へは１周期後に影響を受けるからである。 Note that changing an element on the logic circuits 33 to 35 may affect other elements that use the output of the changed element with a time difference. For example, a case where “calculation Y” affects subsequent elements after one cycle will be described as an example. In the case of this example, for example, if the change point of “change point ID” = “002” is executed at the time of “cycle 1”, the influence degree calculation unit 13 changes the cycle shown in FIG. For the output point 84 of “ID” = “OB”, “cycle” = “1”, and for the output point 85 of “output point ID” = “OE”, “cycle” = “2”. Also good. The reason why the output point 85 of “output point ID” = “OE” is calculated as “cycle” = “2” is that “calculation Y” affects subsequent elements after one cycle. This is because it is affected after one cycle.
　同様に、影響度計算部１３は、「出力点ＩＤ」＝「ＯＦ」の出力点８６に対して「周期２」、「出力点ＩＤ」＝「ＯＡ」の出力点９０に対して「周期」＝「３」のように計算してもよい。出力点８６が「周期」＝「２」と計算されるのは、出力点８５と同様の理由である。また、出力点９０が「周期」＝「３」と計算されるのは、出力点８６の「周期」＝「２」よりも１つ後の周期で出力点９０が影響を受けるからである。 Similarly, the influence degree calculation unit 13 sets “cycle 2” for the output point 86 of “output point ID” = “OF” and “cycle” for the output point 90 of “output point ID” = “OA”. = You may calculate like "3". The reason why the output point 86 is calculated as “period” = “2” is the same reason as the output point 85. The reason why the output point 90 is calculated as “period” = “3” is that the output point 90 is affected in a period immediately after the “period” = “2” of the output point 86.
　このように実施の形態２によれば、経過時間を考慮して変更影響度を計算し表示するので、過去に開発された設計情報の中から新たに開発する設計情報の仕様に近いものをさらに正確に特定することができる。 As described above, according to the second embodiment, since the change influence degree is calculated and displayed in consideration of the elapsed time, the design information newly developed from the design information developed in the past is further improved.
