En körbar systemmodell för beteendeanalyser av rymduppdraget LISA (Swedish)
Abstract [en]

This master thesis report presents the modelling process of key elements of the Laser Interferometer Space Antenna mission (LISA mission) in a Modelbased systems engineering (MBSE) approach with SysML (Systems Modeling Language). The model implements a selected set of functions of the mission through executable graphical representations, called diagrams. It is shown how such diagrams can benefit the mission, by comparing this mean of information exchange to the traditional text- based systems engineering. The model represents the mission structure and behaviour through a system of nested layers. The deeper the layer is, the more it gives details on a system part. Each layer can be seen from different point of views, either focusing on the structure, the behaviour, or the performance of related system part.

Abstract [sv]

I detta examensarbete presenteras modelleringsprocesserna av nyckelelementen i rymduppdraget LISA (Laser Interferometer Space Antenna) inom modellbaserad systemteknik (Model-based systems engineering MBSE) med SysML (Systems Modeling Language). Modellen implementerar en vald uppsättning av uppdragets funktioner genom exekverbara grafiska representationer, kallade diagram. Jag visar hur dessa exekverbara representationer kan vara fördelaktiga för rymduppdraget genom att jämföra detta informationsutbyte med traditionella text-baserade modelleringsprocesser. Modellen representerar hur uppdraget är strukturerat och hur den beter sig i ett system av lager. Ju djupare ett lager är desto mer detaljerad insyn ger det i olika delar av systemet. Varje lager kan ses från olika perspektiv, antingen med fokus på strukturen, på beteendet eller på prestationen av de relaterade systemdelarna.
