4. PUGH CHART - D-Division-2023-24-Odd/Repo-13 GitHub Wiki

Task 1 - Assign weights to the objectives
objectives	Weights
Portability	6
Designs modifiying flexibillity	8
Maintainance	7
Use of standard parts	9

Task 2 : Write Pugh chart for the 4 alternative designs shown in figures
Design Objectives	Weights	Design 1	Design 2	Design 3	Design 4

Portability	6	0	+	-	Datum
Designs modifying flexibility	8	++	+	++	Datum
maintainance	7	0	0	-	Datum
Use of standard parts	9	0	+	+	Datum
Score(+)	16	23	25	-	Datum
Score(-)	0	0	13	-	Datum
Total	16	23	12	-	Datum

	Task 3 : Justification for the scores given
Design No.	Objective	Score Allocated	Justification for the Score
1	Portability	0	it is comparatively same
	Designs modifying flexibility	16	Multiple arms would be much flexible in designs
	maintainance	0	it is comparatively same
	Use of standard parts	0	it is comparatively same
2	Portability	6	power consumtion is high
	Designs modifying flexibility	8	Arm can do more modification than datum
	maintainance	0	it is comparatively same
	Use of standard parts	9	it is affordable
3	Portability	-6	its large in size
	Designs modifying flexibility	16	Its more effective and flexible in designs
	maintainance	-7	Structure is more sensitive than others
	Use of standard parts	9	Effective than datum
4	Portability	0	--------
	Designs modifying flexibility	0	--------
	maintainance	0	--------
	Use of standard parts	0	--------
