5.1 Justification of assigning the weights

Table 3: Justification

design no.	objective	score given	Justification
1	Stamp size	6	the stamp of this design is small
	Machine size	-7	the machine size is bigger then expected
	Machine weight	-8	The machine is heavy
	Machine appearance	5	Machine is better in appearance
2	Stamp size	6	the stamp of this design is small
	Machine size	-7	the machine size is bigger then expected
	Machine weight	0	the machine is a bit heavy
	Machine appearance	-5	Machine is not good in appearance
3	Stamp size	6	the stamp of this design is small
	Machine size	0	its normal
	Machine weight	0	its not heavy
	Machine appearance	12	It is good looking
4	Stamp size	0	datum
	Machine size	0	datum
	Machine weight	0	datum
	Machine appearance	0	datum
