Assign Weights to the objective:

objective	Weights
Safety	2
Ease of use	6
portability	5
Use of standard parts	4
Cost	7

Justification for score given

Design no.	Objectives	Score allocated	Justification for the score
1	Safety	0	Its not safe enough ,as a lot of gears are used
	Ease of use	6	Complexity is high
	Portability	5	dimensions are feasible
	Use of standard parts	4	Quality checked products shall be used
	Cost	7	Cost effective
2	Safety	2	as the gears are placed inside the plank its rather safe
	Ease of use	12	Excepts user input
	Portability	0	Due to large size of the model
	Use of standard parts	4	Quality checked products shall be used
	Cost	7	Cost effective
3	Safety	2	Gear placement makes it safe
	Ease of use	6	As the complexity is low its user friendly
	Use of standard parts	0	The size of model is not apt
	cost	7	cost effective
4	Safety	Datum
	Ease of use	datum
	Use of standard parts	datum
	Cost	datum
