Justification

Design No.	Objective	Score Allocated	Justification for the Score
1	semiautomatic	3	This design is semiautomatic
	light weight	-4	not light in weight as it uses heavy casing
	Portability	5	portable
	User friendly	-9	the sliding mechanism is not reliable and not easy to use
	Cost	0	This requires almost same amount of cost as the datum
	Low Maintenance	-4	Maintenance is required because the slider can be damaged due to friction
2	semiautomatic	3	This design is semiautomatic
	light weight	-4	Not light in weight as the rotating disks are heavy
	Portability	5	Portable
	User friendly	+9	Many standard parts are used to make this
	Cost	-3	This requires more cost than the datum to be produced
	Low Maintenance	-8	More maintenance is required because more than one capsule can be dispensed at times
3	semiautomatic	0	Datum
	light weight	0	Datum
	Portability	0	Datum
	User friendly	0	Datum
	Cost	0	Datum
	Low Maintenance	0	Datum
4	semiautomatic	3	this design is semiautomatic
	light weight	4	This design is preferable as the standard parts are not heavy
	Portability	-5	Not quite portable
	User friendly	+9	It is easy to use
	Cost	3	This requires more cost than the datum to be produced
	Low Maintenance	4	Maintenance is less
