This thesis aims to develop a methodology to translate an ontology to a matrixbased methods that is case independent. In the larger picture this is one of manycomplexities in systems engineering approach. The focus in this work is in the domainof conceptual design, hence, matrix based methods that are most suitable for it areinvestigated. The flexible nature of the ontology always allows for expansion withnew information about the concepts, and from that perspective a parsing scriptwas developed to extract information from the ontology, it was also designed to beflexible. The script can be used to extract any desired type of information by alteringa few keywords as inputs. The advantage is that the same structure of the script canbe used to extract information from many different ontologies.Using this method the matrices relevant for conceptual design were formulated.These matrices were further compared to each other. Also, a few recommendationswere given for the improvement of the method to adapt towards high fidelity. Thecurrent method is capable of solving problems with low fidelity, however this formsa basis to expand the method to high fidelity problems.
