Abstract(J)パワートレーン仕様を表す多数のパラメータから性能向上に対するボトルネックを抽出するための感度解析手法を紹介する。混合整数計画法(MIP)では得られた最適解の近傍においてシステムを定義するパラメータの感度を解析的に得ることが可能である。プラネタリギヤの制約式を例に感度算出手法を示す。

Translation

Abstract(E)This report introduces a sensitivity analysis method for extracting bottlenecks for performance improvement from a large number of parameters that represent power train specifications. In mixed integer programming (MIP), it is possible to analytically obtain the sensitivity of the parameters that define the system in the vicinity of the obtained optimal solution. The sensitivity calculation method is shown using the constraint formula of the planetary gear as an example.

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.
