Appendix IX<br />
In this evaluation matrix, different fasten<strong>in</strong>g concepts<br />
were evaluated accord<strong>in</strong>g to chosen requirements from<br />
the design criteria. See Appendix XIII for the design<br />
criteria. If a requirement was met by the concept, it<br />
got one, two or three po<strong>in</strong>ts accord<strong>in</strong>g to how well it<br />
fulfilled the requirement. If the concept did not meet<br />
the requirement, it scored zero. After hav<strong>in</strong>g decided<br />

upon a score for each requirement for each concept,<br />
the po<strong>in</strong>ts from the pair comparison were <strong>in</strong>serted<br />
<strong>in</strong> order to get more accurate scores. The po<strong>in</strong>ts for<br />
each requirement were multiplied with the po<strong>in</strong>ts for<br />
a concept’s fulfilment of it and thereafter all the scores<br />
for one concept was added. The criteria of low cost<br />
and of ma<strong>in</strong>tenance were divided <strong>in</strong> three columns,<br />
one for a disposable concept, one for a semi disposable<br />
concept and one for a semi reusable concept. Thus, <strong>in</strong><br />
