B. Justification

Design No	Objective	Score allocated	Justification for the score
1	Cost	+	The expenses are less as compared to datum
	Portability	+	It is very easily movable as compared to datum
	User friendly	+	it is easy to use as compared to datum
	Semiautomatic	0	it is semiautomatic as datum
2	Cost	Datum	As reference
	portability	Datum	As reference
	user friendly	Datum	As reference
	Semiautomatic	Datum	As reference
3	Cost	-	The expenses are more as compared to datum
	Portability	+	It is easily movable as compared to datum
	user friendly	+	easy to use as compared to datum
	semiautomatic	++	it is much more semiautomatic as compared to datum
4	cost	++	the expenses are much less as compared to datum
	Portability	+	Easily movable as compared to datum
	User friendly	-	it is not user friendly as compared to datum
	semiautomatic	+	It is more semiautomatic as compared to datum
