The lumped-element model (also called lumped-parameter model, or lumped-component model) simplifies the description of the behaviour of spatially distributed physical systems, such as electrical circuits, into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc. This may be contrasted to distributed parameter systems or models in which the behaviour is distributed spatially and cannot be considered as localized into discrete entities.

rdfs:comment	集中定数回路（しゅうちゅうていすうかいろ、しゅうちゅうじょうすうかいろ）は、取り扱う周波数の波長よりも十分小さい形状の電子部品や十分短い配線長で構成され、かつ、部品間の配線のインピーダンスが無視できるほど小さい回路である。信号が伝播する遅延時間が無視できるほど小さいものと考えられるので、分布定数回路と区別している。 VHF以上の回路では、集中定数回路とされるものであっても、実際には集中定数と分布定数が複合した状態となっているので、設計には特別な配慮が必要である。 (ja) Un dispositivo si dice a parametri concentrati quando presenta una grandezza fisica di valore trascurabile rispetto al valore della stessa grandezza riferita al sistema fisico in cui tale dispositivo agisce. Tale proprietà permette di modellare il comportamento di sistemi distribuiti nello spazio con una topologia consistente di entità discrete. È un approccio usato in elettrotecnica, termodinamica, meccanica e acustica. (it) 集總電路（Lumped circuit）是由許多由電源、電阻、電容、電感等集總元件（ Lumped element）所組成之電路。在電路理想化的電路模型分析，各點之間的信號是瞬間傳遞的，電路元件的所有電流過程都集中於在元件內部空間的各個點上，此為集總電路之特性。每個集總元件基本現象時可用數學方式表示，並建立多種實際元件的理想模型。而電阻、電容、電感、電壓源和電流源都只是儲存或消耗電能磁場的元件，因此都視為集總元件，而且因為只有兩個端口，所以也稱之為二端元件（或者單口元件），除此之外，集總電路還需要理想變壓器、耦合電感、受控源等四端元件（雙口元件）。 (zh) يعمل نموذج العناصر المجمع (المعروف أيضًا باسم نموذج العامل المتغير المجمع أو نموذج المكونات المجمع) على تبسيط وصف سلوك النظم الفيزيائية الموزعة مكانيًا في أي طوبولوجيا مكونة من كيانات منفصلة تقترب من سلوك النظام الموزع وفقًا لافتراضات معينة. وهو مفيد في النظم الكهربائية (بما في ذلك الإلكترونيات) والنظم متعددة العناصر الميكانيكية وانتقال الحرارة وعلم الصوت وما إلى ذلك. (ar) En general, un modelo de parámetros concentrados es un método que simplifica el análisis de un sistema real espacialmente distribuido, mediante la creación de una topología de elementos discretos que aproximan el comportamiento de los componentes distribuidos reales bajo ciertas restricciones.

(en) La modélisation par blocs fonctionnels simplifie la description du comportement d'un système physique distribué en le réduisant à un graphe (ou « topologie ») constitué d’éléments séparés, les blocs fonctionnels. Elle intervient dans les domaines les plus variés, depuis le réseau de distribution à la linguistique en passant par les circuits (thermiques, électriques ou électroniques, pneumatiques, hydrauliques), les robots, l'acoustique, etc. (fr) O modelo de parâmetros concentrados (também chamado de modelo de elementos concentrados ou modelo de componentes concentrados) simplifica a descrição do comportamento de sistemas físicos distribuídos espacialmente em uma topologia que consiste em entidades discretas que aproximam o comportamento do sistema distribuído sob certas premissas. É útil em sistemas elétricos (incluindo eletrônica), sistemas mecânicos de múltiplos corpos, transferência de calor, acústica, etc. (pt)
