 # FAIRe Qualitäts-KPIs
 
 %% Cell type:markdown id:2ee8746d tags:
 
 ## Einführung
 FAIRe Qualitäts-KPIs schaffen eine transparente und nachvollziehbare Entscheidungsgrundlage. In dieser Lerneinheit sollen sie die Methodik erlernen, indem sie LEGO-Autos zusammenbauen, deren Quality KPIs bestimmen und miteinander vergleichen.
 
 ### Werkzeug für den Zusammenbau
 Der Zusammenbau der Autos erfolgt virtuell. Als Werkzeug steht Ihnen das Modul `classes` zur Verfügung. In diesem sind unterschiedliche Klassen und Methoden implementiert (Objektorientierung). Sie erzeugen jeweils Objekte der Klassen. Ein Objekt ist dabei die virtuelle Abbildung eines realen Bauteiles. Die Eigenschaften des Bauteiles werden über die Eigenschaften des Objektes abgebildet.
 
 ### Berechnung der Quality KPIs
 KPIs (Key Performance Indikatoren) sind Kenngrößen des Systems. Sie werden über Berechnungsvorschriften bestimmt. Diese Berechnungsvorschriften sind von Ihnen als python-Funktionen im Modul `calculation_rules` zu implementieren.
 
 ### Datenblätter
 Für den Zusammenbau stehen Ihnen verschiedene Bauteile in unterschiedlichen Ausführungen zur Verfügung. Sie nutzen die Datenblätter, die als `json-Dateien` zur Verfügung gestellt werden, um Ihre Autos zusammenzubauen.
 
 %% Cell type:markdown id:1c702114 tags:
 
 ## Eigene Module und Minimalbeispiel
 Für die Ausarbeitung nutzen wir zwei eigene Module (Python-Dateien), die im Ordner `functions` gespeichert sind.
 Das Modul `calculation_rules` erweitern Sie während der Ausarbeitung. Um die Änderungen zu nutzen, müssen Sie das Notebook neu starten.
 Im Modul `classes` befinden sich die komplette Klassen und Funktionen zur Verwendung.
 
 Mit einem Minimalbeispiel wird Ihnen gezeigt, wie sie die Module nutzen.

 #### Versuchsaufbau:
 Die folgende Abbildung zeigt den Versuchsaufbau des Minimalbeispiels in LeoCAD. Die transparenten Bauteile sind dabei nicht Teil des hier erläuterten Zusammenbaus, können aber mit dem zur Verfügung gestellten Baukasten ergänzt werden:

 %% Cell type:markdown id:6d3310be tags:
 
 ### Modul classes
 Enthält `LegoComponent, LegoAssembly, AggregationLayer, KPIEncoder` und die Funktion `print_assembly_tree`.
 `LegoComponent` bildet einzelne Komponenten ab, während `LegoAssembly` zusammengesetzte Aggregationsebenen abdeckt, also Bauteil, Baugruppe und System. Zur Unterscheidung dient die Klasse `AggregationLayer`, diese ist für `LegoComponent` immer `Component` (Komponente), muss für `LegoAssembly`  entsprechend auf `SYSTEM` (System) , `ASSEMBLY` (Baugruppe) oder `SUBASSEMBLY` (Bauteil) gesetzt werden.
 
 Wir bauen aus Achse, Rahmen und Reifen einen Tretroller zusammen.
