Abstract [en]

This thesis covers a degree project for a Bachelor of Science in mechanical engineering degree and is written on behalf of Valmet AB. The purpose of the project is to evaluate and analyse the differences between CATIA and E3D and conclude which of the software is most suitable for on-machine tubing and piping design at Valmet. The tubing and piping modules in CATIA are currently used but is considered somewhat ineffective. E3D is also used at Valmet but in another branch of engineering design, namely field pipe engineering.

The analysis is done using the analytic hierarchy process (AHP) which is a multi-criteria decision making (MCDM) methodology developed to aid in complex decision-making problems. The methodology follows a six-step process which results in a prioritized ranking or relative weight of both alternatives with respect to the established criteria and sub-criteria for selection. A total of four main criteria and 12 sub-criteria for the selection of the most suitable CAD system were identified and analysed with the help of relevant personnel in various departments such as engineering, purchasing and management

The results of the project conclude that E3D is the preferred CAD system for on-machine tubing and piping at Valmet with regards to the given criteria and sub-criteria. The criteria that favoured E3D most were the availability of the systems, meaning the possibility that Valmet can outsource projects to consultants, as well as the more effective 3D modelling process. However, the results are not heavily one-sided which suggest that more research should be done before a final decision can be taken.

The suggested further research includes looking at the in-direct implications of using a new CAD system such as computer updates and the usage of a new PLM system. Moreover, the actual performance of 3D modelling using the two systems is beyond the scope of this thesis and would have to be further researched in another thesis or a pilot case.
