JUSTIFICATIONS OF PUGH CHART

Design idea no. 1	Objective	Score given	Justification
	Compact size	+	design 1 will have all the components arranged intact as compared to datum
	Minimum time consumption	0	Because both design 1 and datum will consume same amount of time to polish the shoe
	Movement	+	design 1 will have wheels attached hence can be moved easily
	Light weight	-	design 1 will contain more components therefore it will be heavy as compared to datum

Design idea no. 2	Objective	Score given	Justification
	Compact size	+	design 2 will have all the components arranged intact as compared to the datum
	Minimum time consumption	+	the shoe can easily be moved to next compartment through the roller hence less time will be consumed
	Movement	0	both will almost have same weight hence movement of both will be in the same way
	Light weight	-	datum is way too light than design 2 because less components will be used

Design idea no. 3	Objective	Score given	Justification
	Compact size	-	the size of design 3 is huge and requires many components hence datum is better
	Minimum time consumption	-	more time consumption because of the complexity of the design
	Movement	+	trolley will be used to move design 3 hence it can easily be moved as compared to datum
	Light weight	0	both datum and design 3 will have same weight because almost same number of components will be used

Design idea no. 4	Objective	Score given	Justification
	Compact size	datum	--
	Minimum time consumption	datum	--
	Movement	datum	--
	Light weight	datum	--

Energy interaction	No	Yes
Data interaction	Yes	No
Material interaction	Yes	Yes
spatial interaction	No	Yes

Explanation: Sub system 01

There is data interaction between subsystem 01 and subsystem 02 as there is passing of the commands for further process. Since there is usage of shoe,there exist material interaction.Between subsystem 01 and 03 supply of power is needed hence there is energy interaction and also there is transfer of liquid polisher for cleaning.Since the dimensions of the shoe are considered there exists spatial interaction between sub system 01 and 03.

Energy interaction	No	Yes
Data interaction	No	Yes
Material interaction	No	No
Spatial interaction	No	No

Explanation:Sub system 02

There is transfer of energy for the process of cleaning and polishing hence there exists energy interaction between sub system 02 and subsystem 03.Since the commands are passed for the process to start there is data interaction between sub system 02 and 03.

Explanation:Sub system 03:

There exists material interaction between sub system 03 and 01 since shoe is a material here,there also exists spatial interaction since the dimensions of the shoe is required.After the completion of work the machine has to indicate the completion of work hence there exists data interaction between sub system 03 and 02.
