3. Justification of Pugh chart

Design Idea No.	Objective	Score given	Justification
1.	Semi-automatic	18	The wrapping sheets are manually placed in the machine while the chocolates are dispensed automatically
	Safety	8	As the process completes in the machine there is no chance of physical damage
	Easy To Use	-12	As the process completes in the machine there is no chance of physical damage
	Portability	4	As the size of machine is 2X2 it makes portable for the user
	Cost	-10	As there are 3 dipensers and its mechanism it enchances the cost of production increases
2.	Semi-automatic	18	It is because chocolates can be easily wrapped after major part is wrapped
	Safety	-16	Chances that cutter may hit or damage the fingers while collecting chocolate
	Easy To Use	6	Its easy as machine wraps chocolate along the conveyor belt and only the chocolates must be inserted
	Portability	-8	The machine is heavy
	Cost	10	Its cost-Effective

4.	Semi-automatic	-9	The machine is totally automatic as chocolate gets wrapped on its own so cannot be used as semi-automatic
	Safety	16	Machine is safe for the operators and don't cause any harmness to the desired product
	Easy To Use	6	Conceptual machine is user-friendly, almost easy to use and less training is required to operate
	Portability	-8	The machine is very heavy and portability is low
	Cost	5	Its cost-Effective

4.Selected Design

According to the scores given to the conceptual designs in pugh chart, Design 1 is most appropriate for chocolate Wrapping.

5.Clustering of Subfunctions and functions in glass box/Function tree.

6.Identified List of Subsystems

SI.No.	Subsystem Name
1	Insertion and sensing of the chocolate
2	Chocolate Wrapping
3	Collection of wrapped chocolates
4	Indication of Process completion

7.System Interactions Details( For above subsystems)

Interaction Details:

1.Material Interaction: Some solid materials and other packing materials flow through one subsystem to another.

2.Energy Interaction:Some of energy interactions are acting between one subsystem and the other.( Electrical energy in the one subsystem is converted into mechanical energy where work is being done)

3.Data Interactions: Signals used between one subsystem to another will help the packing of chocolate in a systematic way. However the signals of one subsystem are linked with each other.

4.Special Interactions: These are physical connections Between one subsystem to another that defines the whole Machine.

8.System Interaction details table(for all the subsystems)
