Abstract(J)本報は,MBSEに適合するデジタルスレッド基盤を構築し,要求と部品スペックを物理モデルで双方向に結合したうえで,Simulation Process and Data Management(SPDM)による一元管理とイベント駆動の自動ハンドオフにより,要求更新から解析・最適化・設計確定・登録までの自動化を進める運用を実装した事例を報告する.社内案件では,変更→結果反映リードタイムの短縮,トレーサビリティの向上を確認した.

Translation

Abstract(E)This paper reports a digital-thread platform aligned with MBSE that bidirectionally links requirements and component specifications via physics-based models. With SPDM-based unified management and event-driven automated handoffs, it advances automation from requirement updates through analysis/optimization to design finalization and registration. Internal projects showed shorter change-to-result lead time and improved traceability.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
