Description

設計支援装置、設計支援システム、設計支援方法およびプログラム記憶媒体Design support apparatus, design support system, design support method, and program storage medium
　本発明は、システムを開発する際に、それよりも前に発生したシステム障害事例から得られた知見を活用する技術に関する。 The present invention relates to a technology that utilizes knowledge obtained from a system failure case that occurred before the development of a system.
　電力、交通、水道、通信などの社会インフラシステムは人々の暮らしや経済活動を支える重要な基盤であり、多くの利用者が安心して使える高度な信頼性と安全性が要求される。信頼性や安全性が高く、かつ、障害や災害に強く、かつ、人々が安心して使えるシステムは、ディペンダブルシステムと呼ばれる。ディペンダブルシステムを提供することは、社会インフラの提供に携わる事業者（ベンダ、プロバイダ）やオペレータが持つ共通の課題である。 Social infrastructure systems such as electric power, transportation, water supply, and communications are important foundations that support people's lives and economic activities, and they require advanced reliability and safety that many users can use with peace of mind. A system that has high reliability and safety, is resistant to obstacles and disasters, and can be used with peace of mind by people is called a dependable system. Providing a dependable system is a common issue for operators (vendors and providers) and operators involved in providing social infrastructure.
　近年、社会インフラシステムとＩＴ（Information Technology）システムの統合が進んでおり、これにより、社会インフラシステムをソフトウェアによって制御することが可能となってきている。しかしながら、社会インフラシステムをソフトウェアによって制御した実績はまだ十分ではなく、この実績不足のために、開発されたソフトウェアに思わぬ欠陥がある場合がある。また、システム間の連携に不具合が発生する場合がある。さらに、ソフトウェア制御によるシステム動作とシステムを運用する人の操作とにずれが生じ、システムをうまく運用できない場合もある。このような理由により、ソフトウェアによるシステム制御には、システムが正しく動作しない事態や、システムが停止する事態が発生するおそれがあり、システムが長時間に亘って利用できなくなるリスクがある。 In recent years, integration of social infrastructure systems and IT (Information Technology) systems has been progressing, and it has become possible to control social infrastructure systems with software. However, the track record of controlling social infrastructure systems with software is not sufficient, and due to this lack of track record, the developed software may have unexpected defects. In addition, a problem may occur in the cooperation between systems. Furthermore, there may be a difference between the system operation under software control and the operation of the person operating the system, and the system may not be operated successfully. For these reasons, there is a risk that the system may not be used for a long time because there is a possibility that the system will not operate properly or the system will stop in the system control by software.
　未知のリスクに対して問題を完全に未然に防止することは困難であるが、不幸にして起こってしまった事故を二度と起こさないようにシステムの設計や運用を改善していくことは重要である。 Although it is difficult to completely prevent problems against unknown risks, it is important to improve system design and operation so that accidents that have occurred unfortunately will not occur again. .
　近年、障害の事例や知見を業界で広く共有し、社会全体でディペンダブルシステムの提供に役立てていこうとする取り組みが見られる。例えば、社会インフラシステムにおいては、ＩＴシステムの業界だけではなく、システムの提供に携わる様々なステークホルダ（利害関係者）間で障害やリスクの情報を共有していくことが期待されている。非特許文献１には、ＩＴシステムの障害事例が広く業界から集められ、高信頼なシステムを提供していくために利用可能な教訓がまとめられている。 In recent years, there have been efforts to share the cases and knowledge of disabilities widely in the industry and make use of them to provide dependable systems throughout society. For example, in the social infrastructure system, it is expected that not only the IT system industry but also various stakeholders (stakeholders) involved in providing the system will share information on obstacles and risks. Non-Patent Document 1 collects a wide range of IT system failure cases from the industry and summarizes lessons that can be used to provide a highly reliable system.
　しかし、業界を越えて事例や知見が共有されたとしても、その知見をシステムの開発や運用の現場で活用できなければ、システムを効率良く改善できない。また、社会インフラシステムの機能、動作や形態は多様であり、他のシステムで起こった事例が同様に他のシステムでも起こるとは限らない。さらに、事例から得た知見が共有されたとしても、その知見（情報）を活用するかどうかはシステム設計者や運用者の理解度やスキルレベル、経験に頼るところが大きい。すなわち、業界を越えて集められた障害の事例や設計の知見を、新しいシステムの設計において確実に活用していく方法が確立されていない。 However, even if examples and knowledge are shared across industries, the system cannot be improved efficiently unless the knowledge can be utilized in the field of system development and operation. Moreover, the functions, operations, and forms of social infrastructure systems are diverse, and cases that occur in other systems do not always occur in other systems as well. Furthermore, even if knowledge obtained from examples is shared, whether to utilize the knowledge (information) depends largely on the understanding, skill level, and experience of system designers and operators. In other words, there has not been established a method for reliably utilizing failure cases and design knowledge collected across industries in designing a new system.
　さらに、共有された事例や知見を考慮して設計および運用されているシステムにおいて、設計や運用において欠陥が見つかった場合に、その欠陥に関わる知見も広く共有されなければ、他のシステムでも同じ問題に直面してしまう問題がある。ＩＴシステムによって制御される社会インフラシステムのように実績の蓄積が十分でないシステムにおいては、知見を蓄積していきシステムを継続的に改善していく必要がある。しかし、事例や知見を非特許文献１のように公開して共有するだけでは、事例や知見をただ蓄積していくだけであり、このような手法はシステムの改善につながらない。そこで、知見を活用して設計を行い、かつ、運用しているシステムの動作や運用の結果をフィードバックして別のシステムの設計や運用に活用できるようにすることがシステム開発には必要である。しかし、そのような事例や知見に関するフィードバックは任意であり、システムを運用している事業者等の裁量に任されている。つまり、業界を越えて集められた障害の事例や設計の知見をどのように利用するかという方法は確立されていない。 Furthermore, in a system that is designed and operated in consideration of shared cases and knowledge, if a defect is found in the design or operation, if the knowledge related to the defect is not shared widely, the same problem occurs in other systems. There is a problem that you face. In a system that does not have sufficient results, such as a social infrastructure system controlled by an IT system, it is necessary to accumulate knowledge and continuously improve the system. However, just publishing and sharing cases and knowledge as in Non-Patent Document 1 only accumulates cases and knowledge, and such a method does not lead to system improvement. Therefore, it is necessary for system development to make use of knowledge to design and to feed back the operation and results of the operating system so that it can be used for the design and operation of another system. . However, feedback regarding such cases and knowledge is voluntary and is left to the discretion of the operator operating the system. In other words, there is no established method for how to use the case studies and design knowledge collected across industries.
　特許文献１には、システムの改善に関わる技術が開示されている。すなわち、特許文献１は、不完全性と不確実性が潜在的に存在するオープン環境において、システム提供に関わるステークホルダ間でディペンダブルシステムを提供するために合意情報を形成し、その合意内容に従ってシステムを運用する方法を開示している。特許文献１に開示されているシステムは、ステークホルダ間で合意した結果を合意グラフとして残すことにより、システムが想定された通常の運用状態から逸脱したことを検出し、対応する合意情報を抽出する。特許文献１におけるシステムは、このようなステークホルダ間の合意形成に基づいて設計プロセスや障害対応プロセスを定義し、ディペンダビリティを継続的に改善していくように構成されている。 Patent Document 1 discloses a technique related to system improvement. That is, Patent Document 1 forms consensus information for providing a dependable system among stakeholders involved in system provision in an open environment where imperfections and uncertainties exist potentially, and according to the contents of the agreement A method of operating the system is disclosed. The system disclosed in Patent Document 1 detects that the system has deviated from the assumed normal operation state by leaving the result of agreement between stakeholders as an agreement graph, and extracts corresponding agreement information. The system in Patent Document 1 is configured to define a design process and a failure response process based on such consensus formation between stakeholders and continuously improve dependability.
国際公開第２０１４／０７６７５１号International Publication No. 2014/076751
　特許文献１に開示されているシステムでは、ディペンダビリティ提供に関する事例や知見は、合意形成に携わったものの間でしか活用、蓄積されないという課題がある。特許文献１には、他のシステムにおいて得られた合意に基づく知見を、別のステークホルダ間で作る新しいシステムの設計に活用する方法は示されていない。 In the system disclosed in Patent Document 1, there is a problem that cases and knowledge relating to dependability provision are utilized and accumulated only among those involved in consensus building. Patent Document 1 does not show a method for utilizing knowledge based on an agreement obtained in another system for designing a new system created between different stakeholders.
　本発明は上記課題を解決するために考え出された。すなわち、本発明の主な目的は、システムの設計や運用に関わる事例や知見を継続的に蓄積かつ活用していくことができる仕組みを構築し、システムを効率良く改善でき、より良いディペンダブルシステムを提供できる技術を提供することにある。 The present invention has been devised to solve the above problems.

　以下に、本発明に係る実施形態を図面を参照しながら説明する。 Embodiments according to the present invention will be described below with reference to the drawings.
　＜第１実施形態＞
　図１は、本発明に係る第１実施形態の設計支援装置の構成を簡略化して表すブロック図である。第１実施形態の設計支援装置１は、例えばＣＰＵ（Central Processing Unit）を備えたコンピュータであり、内蔵の記憶部８に格納されているコンピュータプログラム（プログラム）をＣＰＵが実行することによって、次のような機能を持つことができる。すなわち、設計支援装置１は、コンピュータにより実現される機能部として、取得部３と、記録部４と、更新部５とを備えている。 <First Embodiment>
FIG. 1 is a block diagram showing a simplified configuration of the design support apparatus according to the first embodiment of the present invention. The design support apparatus 1 according to the first embodiment is a computer including, for example, a CPU (Central Processing Unit). When the CPU executes a computer program (program) stored in the built-in storage unit 8, the following is performed. You can have the following functions. That is, the design support apparatus 1 includes an acquisition unit 3, a recording unit 4, and an update unit 5 as functional units realized by a computer.
　この設計支援装置１は、記憶装置７と接続している。記憶装置７は、情報を記憶する機能を持つ装置であり、当該記憶装置７には、設計事項の情報が格納されている。ここでの設計事項とは、システムの基本構成を表す事項（要素）である。その具体例を挙げると、例えば、設計事項は、“基幹サーバをホットスタンバイ構成にする”、“切り替え機能を定期的にテストする運用にする”というような事項である。また、設計事項には適用情報が関連付けられている。適用情報とは、関連付けられている設計事項がシステムに適用されたか否かの情報に関わる情報であり、例えば、適用された回数（適用回数）を含む。 The design support device 1 is connected to the storage device 7. The storage device 7 is a device having a function of storing information, and the storage device 7 stores design item information. The design items here are items (elements) representing the basic configuration of the system. As a specific example, for example, the design items are items such as “set the core server in a hot standby configuration” and “set the operation to periodically test the switching function”. In addition, application information is associated with the design items. The application information is information related to information on whether or not an associated design item has been applied to the system, and includes, for example, the number of times of application (number of times of application).
　第１実施形態の設計支援装置１における取得部３は、例えば設計を開始する際に、記憶装置７から、設計対象のシステムに関連する設計事項の情報とそれに関連付けられている適用情報を取得する機能を備えている。この取得された設計事項の情報と適用情報は、例えば、設計支援装置１に内蔵されている記憶部８に格納される。 For example, when the design is started, the acquisition unit 3 in the design support apparatus 1 according to the first embodiment acquires, from the storage device 7, design item information related to the design target system and application information associated therewith. It has a function. The acquired design item information and application information are stored, for example, in the storage unit 8 built in the design support apparatus 1.
　記録部４は、取得部３により取得された設計事項の情報が設計対象のシステムに適用（採用）されたか否かの情報を適用有無情報として取得する機能を備えている。具体的には、例えば、記録部４は、設計支援装置１と接続しているディスプレイ装置（図示せず）を制御することにより当該ディスプレイ装置に、設計事項の情報を表示すると共に、適用有無情報を設計支援装置１に入力することを設計者に促す文字等を表示する。そして、適用有無情報が例えば設計者による入力装置（キーボードやマウスなど）の操作により入力されることにより、記録部４は、適用有無情報を取得する。 The recording unit 4 has a function of acquiring, as application presence / absence information, information as to whether or not the design item information acquired by the acquisition unit 3 has been applied (adopted) to the design target system. Specifically, for example, the recording unit 4 controls the display device (not shown) connected to the design support device 1 to display design item information on the display device, and the application presence / absence information. Is displayed to prompt the designer to input to the design support apparatus 1. Then, when the application presence / absence information is input by, for example, an operation of an input device (such as a keyboard or a mouse) by the designer, the recording unit 4 acquires the application presence / absence information.
　そして、記録部４は、取得した適用有無情報に関連する設計事項に関連付けられている適用情報をその適用有無情報に基づいて更新する機能をさらに備えている。 And the recording part 4 is further provided with the function to update the application information linked | related with the design matter relevant to the acquired application presence / absence information based on the application presence / absence information.
　更新部５は、例えば設計対象のシステムの設計完了時に、設計者が記憶装置７の設計事項の情報を更新する指示を設計支援装置１に入力したことを検知した場合に、記憶部８に格納されている設計事項の情報と適用情報を記憶装置７に転送する機能を備えている。これにより、記憶装置７における設計事項の情報と適用情報が更新される。 For example, when the design of the system to be designed is completed, the update unit 5 stores the information in the storage unit 8 when it is detected that the designer inputs an instruction to update the design item information in the storage device 7 to the design support device 1. It has a function of transferring the information on the design items and the application information that have been made to the storage device 7. As a result, design item information and application information in the storage device 7 are updated.
　この第１実施形態の設計支援装置１は、上記のような構成（機能）を持つことにより、設計対象のシステムに関連する設計事項を記憶装置７から取得することができる。これにより、設計者は、その取得した設計事項を参照しながらシステムを設計することができる。さらに、設計支援装置１は、記憶装置７から取得した設計事項を実際にシステムに適用したか否かを表す情報を適用情報として設計事項に関連付けて記憶装置７に蓄積していくことができる。すなわち、設計支援装置１は、システム設計に関わる事例や知見を蓄積かつ活用できる仕組みを構築でき、これにより、システムの効率の良い改善を図ることができる。 The design support apparatus 1 according to the first embodiment has the configuration (function) as described above, so that design items related to the system to be designed can be acquired from the storage device 7. Thus, the designer can design the system while referring to the acquired design items. Furthermore, the design support apparatus 1 can accumulate in the storage device 7 information indicating whether the design items acquired from the storage device 7 have actually been applied to the system in association with the design items as application information. That is, the design support apparatus 1 can construct a mechanism that can accumulate and utilize cases and knowledge related to system design, and thereby can improve the system efficiently.
　図２は、第１実施形態の設計支援装置１を含む設計支援システムの構成を簡略化して表すブロック図である。この設計支援システム１０は、設計支援装置１と、記憶装置７とを備えている。設計支援装置１と記憶装置７は、直接に接続されてもよいし、情報通信網を介して接続されていてもよい。 FIG. 2 is a block diagram showing a simplified configuration of a design support system including the design support apparatus 1 of the first embodiment. The design support system 10 includes a design support apparatus 1 and a storage device 7. The design support apparatus 1 and the storage device 7 may be directly connected or may be connected via an information communication network.
　この設計支援システム１０は、設計支援装置１および記憶装置７を備えているので、設計支援装置１から得られる効果を奏することができる。つまり、設計支援システム１０は、システム設計に関わる事例や知見を蓄積かつ活用できる仕組みを構築でき、これにより、システムの効率の良い改善を図ることができる。 Since the design support system 10 includes the design support device 1 and the storage device 7, it is possible to achieve the effects obtained from the design support device 1. That is, the design support system 10 can construct a mechanism that can accumulate and utilize cases and knowledge related to system design, and thereby can improve the system efficiently.
　＜第２実施形態＞

The acquisition unit 30, the update unit 31, and the recording unit 32 are functional units that are realized, for example, when the CPU executes a computer program. The storage unit 33 is realized by a storage medium such as a hard disk device or a semiconductor memory.
　取得部３０は、例えば外部から与えられる指示に応じて、コンピュータ（データベース装置）２１の記憶装置２４から設計事項２６の情報を取得する機能を備えている。この取得された設計事項２６の情報は、取得部３０によって、記憶部３３に格納される。 The acquisition unit 30 has a function of acquiring information on the design items 26 from the storage device 24 of the computer (database device) 21 in accordance with, for example, an instruction given from the outside. Information about the acquired design item 26 is stored in the storage unit 33 by the acquisition unit 30.
　記録部３２は、取得部３０により取得された設計事項２６が、設計対象のシステムに適用（採用）されたか否かの情報を適用有無情報として取得する機能を備えている。例えば、記録部３２は、ディスプレイ装置（図示せず）を制御することにより、取得部３０により取得された設計事項２６に関連する適用有無情報の入力を設計者等に要求する指示をディスプレイ装置に画面表示させる。記録部３２は、入力装置（例えばキーボードやマウスやタッチパネル等）を利用して設計者等により入力された適用有無情報を取得する。さらに、記録部３２は、その取得した適用有無情報に関連する設計事項２６に関連付けられている適用情報２８をその適用有無情報に基づいて更新する機能を備えている。例えば、設計事項２６がシステムに適用された場合には、記録部３２は、その設計事項２６に関連付けられている適用情報２８である適用回数をインクリメントし、記憶部３３における適用情報２８を更新する。なお、適用情報２８には、適用されたシステムを表すシステム名称等が含まれていてもよい。 The recording unit 32 has a function of acquiring, as application presence / absence information, information as to whether or not the design item 26 acquired by the acquisition unit 30 has been applied (adopted) to the system to be designed. For example, the recording unit 32 controls the display device (not shown), thereby giving an instruction to the display device to request the designer or the like to input application information related to the design matter 26 acquired by the acquisition unit 30. Display on the screen. The recording unit 32 acquires application presence / absence information input by a designer or the like using an input device (for example, a keyboard, a mouse, a touch panel, or the like). Furthermore, the recording unit 32 has a function of updating the application information 28 associated with the design matter 26 related to the acquired application presence / absence information based on the application presence / absence information. For example, when the design item 26 is applied to the system, the recording unit 32 increments the application count that is the application information 28 associated with the design item 26 and updates the application information 28 in the storage unit 33. . The application information 28 may include a system name representing the applied system.
　さらに、記録部３２は、取得した適用有無情報に基づいて、システムに適用されなかった設計事項２６を検知した場合には、その設計事項２６が適用されなかった理由を取得する機能を備えている。例えば、記録部３２は、或る設計事項２６がシステムに適用されなかったことを検知した場合には、ディスプレイ装置の画面に、その設計事項２６を非適用とした理由を記入する欄が表示されるようにディスプレイ装置を制御する。また、記録部３２は、ディスプレイ装置の画面に、その欄に理由を記入することを促すメッセージ等が表示されるようにディスプレイ装置を制御する。さらにまた、記録部３２は、理由が記入された場合には、その理由を、関連する非適用の設計事項２６に関連付けた態様でもって記憶部３３に格納する。図５には、その記憶部３３に格納されている情報の一具体例が表されている。図５の例では、項番２の設計事項２６が、設計対象のシステムに適用されず、その理由として、“コストと運用要件が設計対象のシステムに合わないため”旨の情報が項番２の設計事項２６に関連付けられている。また、項番４の設計事項２６も設計対象のシステムに適用されておらず、その理由として、“項番３の設計事項２６を採用したことにより適用不要である”旨の情報が項番４の設計事項２６に関連付けられている。 Further, the recording unit 32 has a function of acquiring the reason why the design item 26 is not applied when the design item 26 that has not been applied to the system is detected based on the acquired application presence / absence information. . For example, when the recording unit 32 detects that a certain design item 26 has not been applied to the system, a column for entering the reason why the design item 26 is not applied is displayed on the screen of the display device. The display device is controlled to In addition, the recording unit 32 controls the display device so that a message or the like that prompts the user to enter the reason in the column is displayed on the screen of the display device. Furthermore, when the reason is entered, the recording unit 32 stores the reason in the storage unit 33 in a form associated with the related non-applicable design item 26. FIG. 5 shows a specific example of information stored in the storage unit 33. In the example of FIG. 5, the design item 26 of item number 2 is not applied to the system to be designed, and the reason is that information indicating that “cost and operation requirements do not match the system to be designed” is item number 2. Are associated with the design item 26 of FIG. Further, the design item 26 of item number 4 is not applied to the system to be designed, and the reason is that information indicating that “application is not necessary because the design item 26 of item number 3 is adopted” is item number 4 Are associated with the design item 26 of FIG.
　更新部３１は、例えば設計対象のシステムを設計している場合に設計者による入力装置の操作によって入力され、かつ、記憶装置２４には格納（登録）されていない新規の設計事項２６の情報を受け付ける機能を備えている。さらに、更新部３１は、新規の設計事項２６の情報を受け付けた場合には、その新規の設計事項２６が設定された目的（意図）２７の情報を取得する機能も備えている。さらにまた、更新部３１は、そのような新規の設計事項２６とその目的２７の情報と適用情報２８を記憶部３３に格納する機能を備えている。なお、新規の設計事項２６に関連付けられている適用情報２８である適用回数は、初期状態では“０”である。 For example, when designing a system to be designed, the update unit 31 inputs information on a new design item 26 that is input by the operation of the input device by the designer and is not stored (registered) in the storage device 24. It has a function to accept. Further, the update unit 31 has a function of acquiring information on a purpose (intention) 27 in which the new design item 26 is set when information on the new design item 26 is received. Furthermore, the update unit 31 has a function of storing such new design items 26, information on the purpose 27, and application information 28 in the storage unit 33. Note that the number of applications, which is the application information 28 associated with the new design item 26, is “0” in the initial state.
　更新部３１は、さらに、外部から与えられる指示に応じて、記憶部３３に格納されている設計事項２６とそれに関連付けられている各種情報をコンピュータ２１に転送する機能を備えている。これにより、記憶装置２４の設計事項２６とそれに関連付けられている各種情報が記憶装置２４により更新される。 The update unit 31 further has a function of transferring the design items 26 stored in the storage unit 33 and various information associated therewith to the computer 21 in accordance with an instruction given from the outside. As a result, the design item 26 of the storage device 24 and various information associated therewith are updated by the storage device 24.
　第２実施形態の設計支援システム２０は上記のように構成されている。以下に、第２実施形態の設計支援システム２０を構成する設計支援装置であるコンピュータ２２の動作の一例を図６～図８を参照しながら説明する。なお、図６～図８は、コンピュータ２２の動作例を表すフローチャートであり、当該フローチャートは、コンピュータ２２が実行するコンピュータプログラム（プログラム）の処理手順を表している。 The design support system 20 of the second embodiment is configured as described above. Hereinafter, an example of the operation of the computer 22 which is a design support apparatus constituting the design support system 20 of the second embodiment will be described with reference to FIGS. 6 to 8 are flowcharts showing an example of the operation of the computer 22, and the flowchart shows a processing procedure of a computer program (program) executed by the computer 22.
　例えば、設計対象のシステムの開発者（設計者）は、設計（開発）対象のシステムが属する分類や領域を表す例えばキーワードを入力装置によってコンピュータ２２に入力する。コンピュータ２２の取得部３０は、キーワードが入力されたことを検知すると（図６におけるステップＡ１）、当該キーワードをコンピュータ２１に向けて情報通信網２３を通して送信する。この際、取得部３０は、検索指示（つまり、キーワードに関連する設計事項２６を検索し、かつ、その検索結果を返信する指示）をもコンピュータ２１に送信する。 For example, the developer (designer) of the system to be designed inputs, for example, a keyword representing the classification or area to which the system to be designed (development) belongs to the computer 22 using the input device. When the acquisition unit 30 of the computer 22 detects that a keyword has been input (step A1 in FIG. 6), the acquisition unit 30 transmits the keyword to the computer 21 through the information communication network 23. At this time, the acquisition unit 30 also transmits a search instruction (that is, an instruction to search for the design item 26 related to the keyword and return the search result) to the computer 21.
　記憶装置２４に格納されている複数の設計事項２６は、例えば、適用可能なシステム分野等に基づいて分類され、各設計事項２６には、当該分類されたシステム分野に応じたキーワードが関連付けられている。コンピュータ２１は、コンピュータ２２からキーワードおよび検索指示を受け取ると、そのキーワードに応じたキーワードを持つシステム分野の設計事項２６の情報とそれに関連付けられている各種情報を検索し当該検索結果をコンピュータ２２に返信する。このようにして、取得部３０は、コンピュータ２１の記憶装置２４から設計対象のシステムに関連する設計事項２６の情報を取得する（ステップＡ２）。通常、設計対象のシステムに関連する設計事項２６は複数であることにより、例えば、取得部３０は、設計事項２６の情報をリストの態様でもってコンピュータ２１から受信する。そして、取得部３０は、その取得した設計事項２６の情報の複製を作成し、当該作成した情報を記憶部３３に格納する（ステップＡ３）。記憶部３３に格納する設計事項２６の情報の形態は、例えば、表計算形式のファイル形式などの予め定められた適宜な形式とする。 The plurality of design items 26 stored in the storage device 24 are classified based on, for example, an applicable system field, and each design item 26 is associated with a keyword corresponding to the classified system field. Yes. When the computer 21 receives a keyword and a search instruction from the computer 22, the computer 21 searches the system field design information 26 having a keyword corresponding to the keyword and various information associated therewith, and returns the search result to the computer 22. To do. In this way, the acquisition unit 30 acquires information on the design items 26 related to the design target system from the storage device 24 of the computer 21 (step A2). Usually, since there are a plurality of design items 26 related to the system to be designed, for example, the acquisition unit 30 receives information on the design items 26 from the computer 21 in the form of a list. And the acquisition part 30 produces the replication of the information of the acquired design matter 26, and stores the produced information in the memory | storage part 33 (step A3). The form of the information on the design items 26 stored in the storage unit 33 is an appropriate predetermined format such as a spreadsheet format file format, for example.
　なお、上記例では、取得部３０およびコンピュータ２１は、キーワードを利用して設計事項２６を検索している。これに代えて、取得部３０およびコンピュータ２１は、キーワードではなく、例えば設計対象のシステムの分野や領域を特定する分類番号や、コンピュータ（データベース装置）２１が提供する標準的な問い合わせ言語を用いてもよい。 In the above example, the acquisition unit 30 and the computer 21 search for the design item 26 using a keyword. Instead of this, the acquisition unit 30 and the computer 21 use, for example, a classification number that identifies the field or area of the system to be designed, or a standard inquiry language provided by the computer (database device) 21 instead of using keywords. Also good.
　コンピュータ２２は、上記のようにしてコンピュータ２１から設計事項２６の情報を取得する。 The computer 22 acquires information on the design item 26 from the computer 21 as described above.
　次に、記録部３２の動作の一例を説明する。例えば、システムの設計者は、システム設計の過程で、記憶部３３に格納されている設計事項２６のリストを参照する。 Next, an example of the operation of the recording unit 32 will be described. For example, a system designer refers to a list of design items 26 stored in the storage unit 33 in the course of system design.
　記録部３２は、記憶部３３の設計事項２６が参照されたことを検知すると（図７におけるステップＢ１）、その参照した設計事項２６をシステムに適用したか否かの情報（適用有無情報）を入力することを設計者に促す。例えば、記録部３２は、ディスプレイ装置に、そのような情報の入力を促す文字等が表示された画面を表示する。なお、設計事項２６のリストが例えば表計算ファイルの態様でもって記憶部３３に格納されている場合には、上記のような記録部３２の動作は、表計算のプログラムに基づいたコンピュータ２２の動作によって実現することができる。 When the recording unit 32 detects that the design item 26 in the storage unit 33 has been referred to (step B1 in FIG. 7), the recording unit 32 displays information on whether or not the referenced design item 26 has been applied to the system (application presence / absence information). Encourage the designer to enter. For example, the recording unit 32 displays a screen on which characters or the like for prompting input of such information are displayed on the display device. If the list of design items 26 is stored in the storage unit 33 in the form of a spreadsheet file, for example, the operation of the recording unit 32 as described above is the operation of the computer 22 based on the spreadsheet program. Can be realized.
　このようにして、記録部３２は、参照した設計事項２６について適用有無情報を取得する（ステップＢ２）。その後、記録部３２は、設計者等により入力された適用有無情報に基づいて、設計事項２６をシステムに適用したか否かを判断する（ステップＢ３）。これにより、記録部３２は、設計事項２６をシステムに適用しなかった（非適用とした）ことを検知した場合には、その理由を入力することを例えば画面表示を利用して設計者等に促し、当該理由を取得する（ステップＢ６）。例えば、記録部３２は、その理由の入力を必須事項とする。 In this way, the recording unit 32 acquires application presence / absence information for the referenced design item 26 (step B2). Thereafter, the recording unit 32 determines whether or not the design item 26 is applied to the system based on the application presence / absence information input by the designer or the like (step B3). As a result, when the recording unit 32 detects that the design item 26 has not been applied to the system (not applied), the recording unit 32 can input the reason to the designer or the like using a screen display, for example. Prompt and acquire the reason (step B6). For example, the recording unit 32 makes the input of the reason essential.
　また、記録部３２は、設計事項２６をシステムに適用したことを検知した場合には、例えば、その設計事項２６に関連付けられている適用情報２８である適用回数をインクリメントする。 Further, when the recording unit 32 detects that the design item 26 has been applied to the system, for example, the recording unit 32 increments the number of times of application, which is application information 28 associated with the design item 26.
　然る後に、記録部３２は、入力された適用有無情報に基づいた適用情報２８および非適用の場合の理由を、関連する設計事項２６に関連付けた態様で記憶部３３に格納（更新）する（ステップＢ４）。その後、記録部３２は、参照された全ての設計事項２６について適用有無情報を取得し終えたか否かを判断する（ステップＢ５）。これにより、記録部３２は、参照された設計事項２６の中に、適用有無情報を取得していない設計事項２６が有ると判断した場合には、ステップＢ２以降の動作を繰り返す。また、記録部３２は、参照された全ての設計事項２６についての適用有無情報を取得したと判断した場合には、動作を終了する。 Thereafter, the recording unit 32 stores (updates) the application information 28 based on the applied application information and the reason for non-application in the storage unit 33 in a manner associated with the related design item 26 ( Step B4). Thereafter, the recording unit 32 determines whether or not the application presence / absence information has been acquired for all the design items 26 referred to (step B5). Thereby, the recording part 32 repeats operation | movement after step B2, when it is judged that there exists the design matter 26 which has not acquired the application presence information in the referred design matter 26. FIG. In addition, when the recording unit 32 determines that the application presence / absence information for all the referenced design items 26 has been acquired, the operation ends.
　次に、更新部３１の動作の一例を説明する。例えば、システム設計（開発）中に、設計者が、コンピュータ２１の記憶装置２４には格納されていない新規の設計事項２６を設定（設計）する場合がある。このような場合に、新規の設計事項２６を入力したい旨の要求が設計者によってコンピュータ２２に入力されると、この要求に応じて、更新部３１がディスプレイ装置を次のように制御する。例えば、更新部３１は、ディスプレイ装置の画面に、設計事項２６のリストと共に、新規の設計事項２６の情報を記入可能な欄が表示されるようにディスプレイ装置を制御する（図８におけるステップＣ１）。 Next, an example of the operation of the update unit 31 will be described. For example, during system design (development), a designer may set (design) a new design item 26 that is not stored in the storage device 24 of the computer 21. In such a case, when a request for inputting a new design item 26 is input to the computer 22 by the designer, the updating unit 31 controls the display device as follows in response to the request. For example, the update unit 31 controls the display device so that a column in which information on the new design item 26 can be entered is displayed on the screen of the display device together with the list of the design item 26 (step C1 in FIG. 8). .
　その後、更新部３１は、新規の設計事項２６の情報を記入する欄に情報が入力されたか否かを判断する（ステップＣ２）。そして、更新部３１は、新規の設計事項２６の情報が入力されたと判断した場合には、その新規の設計事項２６を設定した目的（意図）２７の入力を設計者に促すことによって当該設計者から目的２７を取得する。その後、更新部３１は、新規の設計事項２６の情報と、その目的２７と、適用情報２８とを関連付けられた態様でもって記憶部３３に格納する（ステップＣ３）。 Thereafter, the update unit 31 determines whether or not information has been input in the column for entering information on the new design item 26 (step C2). When the update unit 31 determines that the information of the new design item 26 has been input, the update unit 31 prompts the designer to input the purpose (intention) 27 in which the new design item 26 is set. The objective 27 is acquired from. Thereafter, the update unit 31 stores the information on the new design item 26, the purpose 27, and the application information 28 in the storage unit 33 in an associated manner (step C3).
　然る後に、更新部３１は、記憶装置２４の更新指示を受け取ると、記憶部３３に格納されている設計事項２６とそれに関連付けられている各種情報をコンピュータ２１の記憶装置２４に向けて情報通信網２３を通して転送する（ステップＣ４）。 After that, when the update unit 31 receives an update instruction for the storage device 24, the update unit 31 transmits information about the design items 26 stored in the storage unit 33 and various information associated therewith to the storage device 24 of the computer 21. The data is transferred through the network 23 (step C4).
　コンピュータ２１は、コンピュータ２２から設計事項２６の情報を受け取ると、新規の設計事項２６については、この新規の設計事項２６および関連付けられている各種情報を記憶装置２４に追加する。また、コンピュータ２１は、既存の設計事項２６については、この既存の設計事項２６に関連付けられている各種情報を記憶装置２４に上書き（更新）する。 When the computer 21 receives the information on the design item 26 from the computer 22, the computer 21 adds the new design item 26 and various associated information to the storage device 24 for the new design item 26. Further, for the existing design item 26, the computer 21 overwrites (updates) various information associated with the existing design item 26 in the storage device 24.
　上記のようにコンピュータ２２の更新部３１によって、コンピュータ（データベース装置）２１の記憶装置２４のデータが更新される。 As described above, the update unit 31 of the computer 22 updates the data in the storage device 24 of the computer (database device) 21.
　なお、設計事項２６には、設計者が他の設計者等と共有したいコメント情報が関連付けられていてもよい。この場合には、例えば、記録部３２は、コメント欄（設計者がコメント等を記載可能な欄）を含む画面が表示されるようにディスプレイ装置を制御する機能を持つ。さらに、記録部３２は、コメント欄に記入された情報を受け取った場合には、当該情報を、関連する設計事項２６に関連付ける機能を備える。 The design item 26 may be associated with comment information that the designer wants to share with other designers. In this case, for example, the recording unit 32 has a function of controlling the display device so that a screen including a comment column (a column in which a designer can write a comment or the like) is displayed. Further, when receiving information entered in the comment field, the recording unit 32 has a function of associating the information with the related design item 26.

That is, the computer 22 according to the second embodiment can acquire a list of design items 26 that can be used in the field of system development from the computer (database device) 21. In addition, the design information 26 is associated with application information 28 indicating the application status to the system and the reason for non-application. In this way, the system designer can use the design support system 20 to utilize the cases and knowledge obtained in other systems for the design and operation of the system to be designed.
　また、第２実施形態の設計支援システム２０は、既存の設計事項２６の適用結果や、新規の設計事項２６を記憶装置２４に追記することができる。このため、設計支援システム２０は、ディペンダブルシステムを提供するために事例や知見を継続的に記憶装置２４に蓄積できる。 Also, the design support system 20 of the second embodiment can add the application result of the existing design item 26 and the new design item 26 to the storage device 24. For this reason, the design support system 20 can continuously accumulate cases and knowledge in the storage device 24 in order to provide a dependable system.
　上記のようなことにより、設計支援システム２０は、システムを効率良く改善することを支援でき、より良いディペンダブルシステムを提供できる。 As described above, the design support system 20 can support efficient improvement of the system and can provide a better dependable system.

　すなわち、取得部３０は、例えば設計者により入力された情報に基づいてコンピュータ（データベース装置）２１の記憶装置２４から設計事項２６の情報（リスト）を取得した後に、その取得した設計事項２６に関連付けられている参考情報を参照する。そして、取得部３０は、その参考情報に挙げられている設計事項２６を記憶装置２４から取得しているか否かを判断し、取得していない場合には、その未取得の設計事項２６の情報を記憶装置２４から取得する。さらに、取得部３０は、その取得した設計事項２６に関連付けられている参考情報を参照し、上記同様に、参考情報に挙げられている設計事項２６の情報を記憶装置２４から取得しているか否かを判断する。そして、取得部３０は、取得していない設計事項２６の情報がある場合には、さらに、その未取得の設計事項２６の情報を記憶装置２４から取得する。このように、取得部３０は、取得した設計事項２６に関連付けられている参考情報に基づいて、設計事項２６の情報を取得する動作を繰り返す。取得部３０は、取得した全ての設計事項２６およびそれに関連付けられている情報を記憶部３３に格納する。 That is, for example, the acquisition unit 30 acquires information (list) of the design items 26 from the storage device 24 of the computer (database device) 21 based on information input by the designer, and then associates the information with the acquired design items 26. Refer to the reference information provided. Then, the acquisition unit 30 determines whether or not the design item 26 listed in the reference information has been acquired from the storage device 24, and if not, information on the unacquired design item 26 is obtained. Is obtained from the storage device 24. Furthermore, the acquisition unit 30 refers to the reference information associated with the acquired design item 26, and similarly to the above, whether or not the information on the design item 26 listed in the reference information is acquired from the storage device 24. Determine whether. Then, when there is information on the design item 26 that has not been acquired, the acquisition unit 30 further acquires information on the unacquired design item 26 from the storage device 24. As described above, the acquisition unit 30 repeats the operation of acquiring information on the design item 26 based on the reference information associated with the acquired design item 26. The acquisition unit 30 stores all the acquired design items 26 and information associated therewith in the storage unit 33.
　このような取得部３０の機能によって、コンピュータ２２は、例えばキーワード等により指定した設計事項２６だけでなく、参照が推奨される他の設計事項２６の情報をも取得でき、それら取得した全ての設計事項２６の情報を設計者に提供できる。つまり、設計者は、キーワード等により指定した設計事項２６だけでなく、関連する、より多くの設計事項２６の情報を参照することが可能となる。 With such a function of the acquisition unit 30, the computer 22 can acquire not only the design items 26 specified by, for example, keywords but also information on other design items 26 recommended for reference, and all the acquired designs. Information on item 26 can be provided to the designer. That is, the designer can refer to not only the design item 26 specified by the keyword or the like but also more related information on the design item 26.
　記録部３２は、記憶部３３に格納されている設計事項２６に関し、第２実施形態と同様に、参照された設計事項２６が設計対象のシステムに適用されたか否かの情報を適用有無情報として取得する。 The recording unit 32 relates to the design item 26 stored in the storage unit 33, as in the second embodiment, information on whether or not the referenced design item 26 has been applied to the design target system as application presence / absence information. get.
　更新部３１は、新規の設計事項２６が設定（入力）されたことを検知した場合には、その新規の設計事項２６に関連付ける参考情報を設計者から受け付ける機能をさらに備えている。例えば、更新部３１は、ディスプレイ装置における新規の設計事項２６を記入する欄を含む画面において、参考情報を記入する欄をも設けると共に、参考情報の記入を促す文字等を画面表示するようにディスプレイ装置を制御する。 When the update unit 31 detects that a new design item 26 is set (input), the update unit 31 further has a function of receiving reference information associated with the new design item 26 from the designer. For example, the update unit 31 includes a field for entering reference information on a screen including a field for entering a new design item 26 in the display device, and displays a character or the like that prompts entry of the reference information on the screen. Control the device.
　第３実施形態における設計支援システム２０の上記以外の構成は、第２実施形態と同様であり、ここでは、その説明は省略する。 Other configurations of the design support system 20 in the third embodiment are the same as those in the second embodiment, and the description thereof is omitted here.
　この第３実施形態のコンピュータ（設計支援装置）２２および設計支援システム２０は上記のように構成されている。以下に、この設計支援システム２０におけるコンピュータ２２の動作例を図１０と図１１を利用して説明する。なお、図１０と図１１は、それぞれ、コンピュータ２２の動作例を表すフローチャートであり、当該フローチャートは、コンピュータ２２が実行するコンピュータプログラムの処理手順を表している。 The computer (design support apparatus) 22 and the design support system 20 of the third embodiment are configured as described above. Hereinafter, an operation example of the computer 22 in the design support system 20 will be described with reference to FIGS. 10 and 11. FIG. 10 and FIG. 11 are flowcharts each showing an operation example of the computer 22, and the flowchart shows a processing procedure of a computer program executed by the computer 22.
　例えば、コンピュータ２２の取得部３０は、設計者の操作によって入力装置によりキーワードが入力されたことを検知すると（図１０のステップＤ１）、記憶装置２４から、キーワードに応じた設計事項２６および関連する各種情報を取得する（ステップＤ２）。そして、取得部３０は、その取得した設計事項２６に関連付けられた参考情報が有るか否かを判断する（ステップＤ３）。取得部３０は、参考情報が無いと判断した場合には、取得した全ての設計事項２６およびそれに関連付けられている各種情報を記憶部３３に格納する（ステップＤ６）。一方、取得部３０は、取得した設計事項２６に参考情報が関連付けられていると判断した場合には、その参考情報に、取得していない未取得の設計事項２６が有るか否かを判断する（ステップＤ４）。例えば、取得部３０は、図９に表されているような設計事項２６およびそれに関連付けられている各種情報を取得したとする。この場合には、図９の例では、項番１の設計事項２６に関連付けられている参考情報は、項番２，３，４，５の設計事項２６である。また、項番３の設計事項２６に関連付けられている参考情報は、項番４の設計事項２６であり、項番４の設計事項２６に関連付けられている参考情報は、項番３の設計事項２６である。つまり、この図９の例では、取得していない未取得の設計事項２６は無い。これにより、取得部３０は、未取得の設計事項２６が無いと判断し、取得した全ての設計事項２６およびそれに関連付けられている情報を記憶部３３に格納する（ステップＤ６）。 For example, when the acquisition unit 30 of the computer 22 detects that a keyword has been input by the input device by a designer's operation (step D1 in FIG. 10), the design item 26 corresponding to the keyword and the related items are stored from the storage device 24. Various information is acquired (step D2). And the acquisition part 30 judges whether there exists the reference information linked | related with the acquired design matter 26 (step D3). If the acquisition unit 30 determines that there is no reference information, the acquisition unit 30 stores all the acquired design items 26 and various information associated therewith in the storage unit 33 (step D6). On the other hand, when it is determined that the reference information is associated with the acquired design item 26, the acquisition unit 30 determines whether the reference information includes an unacquired design item 26 that has not been acquired. (Step D4). For example, it is assumed that the acquisition unit 30 acquires the design item 26 as shown in FIG. 9 and various pieces of information associated therewith. In this case, in the example of FIG. 9, the reference information associated with the design item 26 of item number 1 is the design item 26 of item numbers 2, 3, 4, and 5. The reference information associated with the design item 26 of item number 3 is the design item 26 of item number 4, and the reference information associated with the design item 26 of item number 4 is the design item of item number 3. 26. That is, in the example of FIG. 9, there is no unacquired design item 26 that has not been acquired. Thereby, the acquisition unit 30 determines that there are no unacquired design items 26, and stores all the acquired design items 26 and information associated therewith in the storage unit 33 (step D6).
　また、取得部３０は、参考情報に基づいた未取得の設計事項２６が有ると判断した場合には、その未取得の設計事項２６を記憶装置２４から取得する動作を実行する（ステップＤ５）。そして、取得部３０は、ステップＤ３以降の動作を繰り返す。 Further, when it is determined that there is an unacquired design item 26 based on the reference information, the acquisition unit 30 executes an operation of acquiring the unacquired design item 26 from the storage device 24 (step D5). And the acquisition part 30 repeats the operation | movement after step D3.
　この第３実施形態では、取得部３０は、上記のような動作によって記憶装置２４から設計事項２６およびそれに関連付けられている各種情報を取得する。 In the third embodiment, the acquisition unit 30 acquires the design item 26 and various types of information associated therewith from the storage device 24 by the operation as described above.
　次に、更新部３１の動作例を図１１に基づいて説明する。例えば、更新部３１は、第２実施形態と同様に、ディスプレイ装置の画面に、設計事項２６のリストと共に、新規の設計事項２６の情報を記入可能な欄が表示されるようにディスプレイ装置を制御する（図１１におけるステップＥ１）。その後、更新部３１は、新規の設計事項２６の情報を記入する欄に情報が入力されたか否かを判断する（ステップＥ２）。これにより、更新部３１は、新規の設計事項２６が入力されたと判断した場合には、その新規の設計事項２６を設定した目的（意図）２７の情報を取得すると共に、新規の設計事項２６に関連付ける参考情報を受け付ける（ステップＥ３）。そして、更新部３１は、新規の設計事項２６およびこれに関連付けられる各種情報を記憶部３３に格納する（ステップＥ４）。然る後に、更新部３１は、記憶装置２４の更新指示を受け取ると、記憶部３３に格納されている設計事項２６とそれに関連付けられている各種情報をコンピュータ２１の記憶装置２４に向けて情報通信網２３を通して転送する（ステップＥ５）。 Next, an operation example of the updating unit 31 will be described with reference to FIG. For example, as in the second embodiment, the update unit 31 controls the display device so that a column in which information about the new design item 26 can be entered is displayed on the screen of the display device together with the list of the design item 26. (Step E1 in FIG. 11). Thereafter, the update unit 31 determines whether or not information is input in a field for entering information on the new design item 26 (step E2). As a result, when the update unit 31 determines that a new design item 26 has been input, the update unit 31 acquires information on the purpose (intention) 27 in which the new design item 26 is set, and the new design item 26 Reference information to be associated is received (step E3). And the update part 31 stores the new design matter 26 and the various information linked | related with this in the memory | storage part 33 (step E4). After that, when the update unit 31 receives an update instruction for the storage device 24, the update unit 31 transmits information about the design items 26 stored in the storage unit 33 and various information associated therewith to the storage device 24 of the computer 21. The data is transferred through the network 23 (step E5).
　この第３実施形態では、設計事項２６には、関連する他の設計事項２６を表す情報が参考情報として関連付けられている。このため、この第３実施形態の設計支援システム２０は、システムを設計する際に参考となる事例や知見を、構造的に蓄積していくことができる。また、この設計支援システム２０は、システムの設計時に、それら蓄積されている事例や知見の活用をより促進することができるようになる。この設計支援システム２０を利用することにより、例えば、設計者は、設計時において考慮すべき設計事項の抽出漏れを防ぐことができる。さらにまた、設計支援システム２０は、システム設計に関わる知識データベースにおいて設計事項の無駄な重複を削減できる。 In the third embodiment, the design item 26 is associated with information representing another related design item 26 as reference information. For this reason, the design support system 20 of the third embodiment can structurally accumulate examples and knowledge that are used as references when designing the system. In addition, the design support system 20 can further promote the utilization of the accumulated cases and knowledge when designing the system. By using this design support system 20, for example, the designer can prevent omission of extraction of design items to be considered at the time of design. Furthermore, the design support system 20 can reduce unnecessary duplication of design items in a knowledge database related to system design.
　＜第４実施形態＞
　以下に、本発明に係る第４実施形態を説明する。なお、この第４実施形態の説明において、第２や第３の実施形態の設計支援システムを構成する構成部分と同様な構成部分には同一符号を付し、その共通部分の重複説明は省略する。 <Fourth embodiment>
The fourth embodiment according to the present invention will be described below. In the description of the fourth embodiment, the same components as those configuring the design support system of the second and third embodiments are denoted by the same reference numerals, and the duplicate description of the common portions is omitted. .
　この第４実施形態では、適用情報２８には、適用回数の情報と、失敗の回数およびその説明の情報とが含まれている。適用回数の情報とは、関連付けられている設計事項２６がシステムに適用された回数の情報である。失敗の回数の情報とは、関連付けられている設計事項２６を適用したことにより生じたシステムの不具合（失敗）の回数の情報である。失敗の説明とは、失敗の内容や原因などの失敗（不具合）に関する情報である。 In this fourth embodiment, the application information 28 includes information on the number of times of application, information on the number of times of failure, and information on the number of failures. The information on the number of times of application is information on the number of times that the associated design item 26 is applied to the system. The information on the number of failures is information on the number of system failures (failures) caused by applying the associated design item 26. The description of failure is information on failure (defect) such as the content and cause of failure.
　記録部３２は、上記のような適用情報２８を取得する機能を備えている。つまり、記録部３２は、第２又は第３の実施形態における機能に加えて、失敗に関する情報を取得する機能を備えている。例えば、記録部３２は、予め定められたタイミングで（システム障害の原因を調べるために記憶装置２４の設計事項２６を参照したタイミングなど）、その参照した設計事項２６のシステム適用が失敗であったことを表す情報の入力を例えば設計者に促す。具体例としては、記録部３２は、そのような失敗に関する情報を入力する画面が表示されるようにディスプレイ装置を制御する。 The recording unit 32 has a function of acquiring the application information 28 as described above. That is, the recording unit 32 has a function of acquiring information related to failure in addition to the functions in the second or third embodiment. For example, the recording unit 32 has failed to apply the referenced design item 26 to the system at a predetermined timing (for example, timing when the design item 26 of the storage device 24 is referred to investigate the cause of the system failure). For example, the designer is prompted to input information representing the above. As a specific example, the recording unit 32 controls the display device so that a screen for inputting information regarding such a failure is displayed.
　この第４実施形態では、上記のように、設計事項２６に関連付けられている適用情報２８には、失敗回数の情報をも含まれている。記録部３２は、設計者等による入力装置の操作によって入力された情報に基づいて、システム適用が失敗であった設計事項２６があることを検知した場合には、その失敗した設計事項２６に関連付けられている適用情報２８の失敗回数をインクリメントする。さらに、記録部３２は、その失敗に関する情報（例えば失敗の内容説明や原因など）をディスプレイ装置と入力装置を利用して設計者等から取得し、これら失敗に関する情報を設計事項２６に関連付けた態様でもって記憶部３３に格納する。図１２には、失敗回数を含む適用情報２８を持つ記憶部３３の格納情報の一具体例が表されている。 In the fourth embodiment, as described above, the application information 28 associated with the design item 26 includes information on the number of failures. When the recording unit 32 detects that there is a design matter 26 in which the system application has failed based on information input by the operation of the input device by the designer or the like, the recording unit 32 associates with the failed design matter 26. The failure count of the applied information 28 is incremented. Further, the recording unit 32 obtains information about the failure (for example, description of the content of the failure and the cause) from the designer using the display device and the input device, and associates the information about the failure with the design item 26. Therefore, it is stored in the storage unit 33. FIG. 12 shows a specific example of information stored in the storage unit 33 having the application information 28 including the number of failures.
　第４実施形態における設計支援システム２０の上記以外の構成は、第２又は第３の実施形態と同様であり、ここでは、その説明は省略する。 Other configurations of the design support system 20 in the fourth embodiment are the same as those in the second or third embodiment, and the description thereof is omitted here.
　第４実施形態の設計支援システム２０は、失敗に関する情報を設計事項２６に関連付けて蓄積できるので、例えば、システム障害を別のシステムで発生させないように、設計対象のシステムを設計することを効果的に支援できる。 Since the design support system 20 according to the fourth embodiment can accumulate information relating to the failure in association with the design item 26, for example, it is effective to design the design target system so that a system failure does not occur in another system. Can help.
　＜第５実施形態＞
　以下に、本発明に係る第５実施形態を説明する。なお、この第５実施形態の説明において、第４の実施形態の設計支援システムを構成する構成部分と同様な構成部分には同一符号を付し、その共通部分の重複説明は省略する。 <Fifth Embodiment>
The fifth embodiment according to the present invention will be described below. In the description of the fifth embodiment, the same components as those configuring the design support system of the fourth embodiment are denoted by the same reference numerals, and the duplicate description of the common portions is omitted.
　図１３は、第５実施形態の設計支援システムの構成を簡略化して表すブロック図である。この第５実施形態の設計支援システム２０は、第４実施形態の構成に加えて、コンピュータ（設計支援装置）２２に、計算部３４が備えられている。また、設計事項２６には、システムの設計における重要度を表す重要度２９の情報が関連付けられている。 FIG. 13 is a block diagram showing a simplified configuration of the design support system of the fifth embodiment. In the design support system 20 of the fifth embodiment, a computer (design support apparatus) 22 includes a calculation unit 34 in addition to the configuration of the fourth embodiment. Also, the design item 26 is associated with information on importance 29 indicating the importance in system design.
　計算部３４は、予め定められたタイミング（例えば、記憶部３３に格納されている設計事項２６に関連付けられている適用情報２８が更新されたタイミング）で、設計事項２６に関連付ける重要度２９を算出する機能を備えている。この第４実施形態では、重要度２９は、適用回数と失敗回数を考慮して算出される。この重要度２９を算出する手法には、様々な手法が考えられるが、ここで、その一具体例を挙げる。例えば、設計事項２６の適用回数を“Ｎ”とし、失敗回数を“Ｍ”とし、重要度２９を“Ｐ”とした場合に、計算部３４は、数式：Ｐ＝ａ×Ｎ－ｂ×Ｍ（ａ，ｂは、零よりも大きい定数）に従って重要度２９を算出する。このように重要度２９を算出する場合には、適用回数Ｎが多いほど重要度２９は大きくなる。また、失敗回数Ｍが少ないほど重要度２９は大きくなる。 The calculation unit 34 calculates the importance 29 associated with the design item 26 at a predetermined timing (for example, timing when the application information 28 associated with the design item 26 stored in the storage unit 33 is updated). It has a function to do. In the fourth embodiment, the importance 29 is calculated in consideration of the number of times of application and the number of failures. Various methods can be considered as a method for calculating the importance 29, and a specific example is given here. For example, when the number of application of the design item 26 is “N”, the number of failures is “M”, and the importance 29 is “P”, the calculation unit 34 calculates the formula: P = a × N−b × M The importance 29 is calculated according to (a and b are constants greater than zero). When the importance level 29 is calculated in this way, the importance level 29 increases as the number of applications N increases. In addition, the importance 29 increases as the number of failures M decreases.
　計算部３４は、算出した重要度２９の情報を、関連する設計事項２６に関連付けた態様でもって記憶部３３に格納する。 The calculation unit 34 stores the calculated importance 29 information in the storage unit 33 in a manner associated with the related design item 26.
　第５実施形態における設計支援システム２０の上記以外の構成は、第４実施形態と同様であり、ここでは、その説明は省略する。 Other configurations of the design support system 20 in the fifth embodiment are the same as those in the fourth embodiment, and a description thereof is omitted here.
　この第５実施形態の設計支援システム２０では、計算部３４によって、適用回数と失敗回数に基づいて設計事項２６の重要度２９が算出され、当該重要度２９の情報が設計事項２６に関連付けられている。これにより、コンピュータ２２は、例えば、設計事項２６の情報を設計者等に提供する場合に、記憶部３３の複数の設計事項２６を重要度順に並べてディスプレイ装置に表示させることが可能である。つまり、適用される可能性の高い設計事項２６が目につきやすい位置に画面表示されるので、設計者は設計支援システム２０をより使い易くなる。つまり、設計支援システム２０は、その利便性を高めることができる。 In the design support system 20 of the fifth embodiment, the calculation unit 34 calculates the importance 29 of the design item 26 based on the number of times of application and the number of failures, and the information on the importance 29 is associated with the design item 26. Yes. Thereby, for example, when providing information on the design item 26 to a designer or the like, the computer 22 can display the plurality of design items 26 in the storage unit 33 in order of importance on the display device. That is, the design item 26 that is likely to be applied is displayed on the screen at a position that is easily noticeable, so that the designer can use the design support system 20 more easily. That is, the design support system 20 can improve the convenience.
　次に、この第５実施形態におけるコンピュータ２２が失敗に関する情報を追記する動作の一例を図１４に基づいて説明する。なお、図１４は、コンピュータ２２の動作の一例を表すフローチャートであり、このフローチャートはコンピュータ２２が実行する処理手順を表している。 Next, an example of an operation in which the computer 22 according to the fifth embodiment additionally writes information regarding a failure will be described with reference to FIG. FIG. 14 is a flowchart showing an example of the operation of the computer 22, and this flowchart shows a processing procedure executed by the computer 22.
　例えば、システムに障害が発生したことにより、設計者等がその障害分析を実施すべく、記憶装置２４の設計事項２６の情報を取得する指示をコンピュータ２２に入力したとする。コンピュータ２２の取得部３０は、その指示に応じて、分析対象の設計事項２６の情報およびそれに関連付けられている各種情報を記憶装置２４から取得する（図１４におけるステップＨ１）。その後、例えばディスプレイ装置に表示された設計事項２６のリストを見ながら、設計者が各設計事項２６について障害の原因になったか否かを判断し、その判断結果の情報をコンピュータ２２に入力する。記録部３２は、その入力された情報に基づいて、設計事項２６が障害の原因であったか否かを判断する（ステップＨ２）。そして、分析対象の設計事項２６に障害の原因がなかったと判断した場合には、コンピュータ２２は、実行中の動作を終了する。 For example, it is assumed that, due to a failure in the system, a designer or the like inputs an instruction to acquire information on the design items 26 in the storage device 24 to the computer 22 in order to perform the failure analysis. In response to the instruction, the acquisition unit 30 of the computer 22 acquires information on the design item 26 to be analyzed and various information associated therewith from the storage device 24 (step H1 in FIG. 14). Thereafter, for example, while looking at the list of design items 26 displayed on the display device, the designer determines whether or not each design item 26 caused a failure, and inputs information on the determination result to the computer 22. Based on the input information, the recording unit 32 determines whether or not the design item 26 is the cause of the failure (step H2). If it is determined that there is no cause of failure in the design item 26 to be analyzed, the computer 22 ends the operation being executed.
　これに対し、障害の原因になった設計事項２６があった場合には、記録部３２は、その障害の原因になった設計事項（失敗した設計事項）２６に関連付けられている適用情報２８の失敗回数をインクリメントする。また、記録部３２は、その失敗の内容説明や原因等の情報を受け付ける（ステップＨ３）。 On the other hand, when there is a design matter 26 that causes the failure, the recording unit 32 stores the application information 28 associated with the design matter (failed design matter) 26 that caused the failure. Increment the number of failures. Further, the recording unit 32 accepts information such as the content explanation and cause of the failure (step H3).
　然る後に、記録部３２は、失敗に関連する情報を記憶部３３に格納（更新）する（ステップＨ４）。そして、計算部３４は、更新された適用情報２８に基づいて、重要度２９を算出し、記憶部３３における重要度２９を更新する（ステップＨ５）。 Thereafter, the recording unit 32 stores (updates) information related to the failure in the storage unit 33 (step H4). Then, the calculation unit 34 calculates the importance 29 based on the updated application information 28, and updates the importance 29 in the storage unit 33 (step H5).
　なお、この第５実施形態では、重要度を算出する計算部３４はコンピュータ２２が備えているが、これに代えて、計算部３４は、図１３の点線に表されているように、コンピュータ２１に備えられてもよい。この場合には、例えば、計算部３４は、記憶装置２４における設計事項２６の情報が更新された場合に、上記同様に、設計事項２６に関連付けられた情報に基づいて重要度２９を算出する。 In the fifth embodiment, the computer 22 is provided with the calculation unit 34 for calculating the degree of importance. Instead, the calculation unit 34 includes the computer 21 as shown by a dotted line in FIG. May be provided. In this case, for example, when the information on the design item 26 in the storage device 24 is updated, the calculation unit 34 calculates the importance 29 based on the information associated with the design item 26 as described above.
　また、計算部３４は、重要度２９に加えて、設計事項２６に関連付けられている情報（例えば参考情報など）に基づき、失敗による被害度（被害が及んだ範囲を表す情報）や深刻度（失敗に関与した度合い）をも算出してもよい。さらに、計算部３４は、その算出した被害度や深刻度の情報を、関連する設計事項２６に関連付けられた態様でもって記憶部３３に格納する。 In addition to the importance level 29, the calculation unit 34 determines the degree of damage (information indicating the extent of damage) and the severity level based on information associated with the design item 26 (for example, reference information). (The degree of participation in failure) may also be calculated. Furthermore, the calculation unit 34 stores the calculated damage degree and severity information in the storage unit 33 in a manner associated with the related design item 26.
　さらにまた、計算部３４は、適用回数と失敗回数だけでなく、算出した被害度や深刻度をも利用して、重要度２９を算出してもよい。この場合には、例えば、設計事項２６の適用回数を“Ｎ”とし、失敗回数を“Ｍ”とし、被害度を“Ｄ”とし、重要度を“Ｐ”とした場合に、計算部３４は、数式：Ｐ＝ａ×Ｎ－ｂ×Ｍ×Ｄ（ａ，ｂは、零よりも大きい定数）に従って重要度２９を算出する。 Furthermore, the calculation unit 34 may calculate the importance 29 using not only the application count and the failure count but also the calculated damage level and severity. In this case, for example, when the application count of the design item 26 is “N”, the failure count is “M”, the damage level is “D”, and the importance level is “P”, the calculation unit 34 The importance 29 is calculated according to the following equation: P = a × N−b × M × D (a and b are constants greater than zero).
　＜その他の実施形態＞
　なお、本発明は第１～第５の実施形態に限定されず、様々な実施形態を採り得る。例えば、第１～第５の各実施形態では、データベース装置として機能する記憶装置７あるいはコンピュータ２１には、１台の設計支援装置１あるいはコンピュータ２２が接続されている。これに対し、設計事項の情報が蓄積されるデータベース装置には、複数の設計支援装置が接続されていてもよい。この場合には、設計事項２６に関する情報を収集しやすくなる。 <Other embodiments>

On the other hand, a plurality of design support devices may be connected to a database device in which design item information is stored. In this case, it becomes easy to collect information on the design item 26.
