Representation av Fordonssystem Genom Produktarkitekturvyer (Swedish)
Abstract [en]

This thesis aimsto identify and propose suitable product architecture views in order to facilitate efficient cross-functional communication and collaboration on architecture-related tasks. It thereby focuses on the relationships between components of a system while determining a suitable level of detailing which is called level of abstraction for the relationships the components share. There is abundant information present such as relationships between hardware component, component specific information and ECU modules in specific and separate documents/files but there is no single representation model which gives holistic representation for vehicular system at SCANIA. Hence, the determined levels of abstraction are implemented onto a representation model to visualize the systems. Key findings during the course of the work in this thesis project includes identifying a suitable level of abstraction for the relationships information, method to reduce the cognitive complexity in the representation models followed by getting to know if the proposed representation model is suitable for the relevant personnel/teams to visualize and obtain information. A case study was made and evaluation was done through means of a questionnaire and an evaluation table provided to the employees in the mentioned teams at the Research and Development department of SCANIA CV AB. The results upon implementation have indicated that the work done has a good level of utility.

Abstract [sv]

Detta examensarbete syftar till att identifiera och föreslå lämpliga produktarkitekturvyer för att underlätta effektiv tvärfunktionell kommunikation och samarbete kring arkitekturrelaterade uppgifter. Den fokuserar därmed på relationerna mellan komponenter i ett system samtidigt som den bestämmer en lämplig nivå av detaljering som kallas abstraktionsnivå för de relationer som komponenterna delar. Det finns rikligt med information som t.ex. relationer mellan hårdvarukomponent, komponentspecifik information och ECU-moduler i specifika och separata dokument/filer, men det finns ingen enskild representationsmodell som ger holistisk representation för fordonssystem hos SCANIA. Därför implementeras de bestämda abstraktionsnivåerna på en representationsmodell för att visualisera systemen. Nyckelfynd under arbetets gång i detta examensarbete inkluderar att identifiera en lämplig abstraktionsnivå för relationsinformationen, metod för att minska den kognitiva komplexiteten i representationsmodellerna följt av att ta reda på om den föreslagna representationsmodellen är lämplig för den relevanta personalen/team för att visualisera och få information. En fallstudie gjordes och utvärdering gjordes med hjälp av ett frågeformulär och en tabell som gavs till de anställda i de nämnda teamen på forsknings- och utvecklingsavdelningen på SCANIA CV AB. Resultaten vid implementering har visat att det utförda arbetet har en god nytta.
