1. Calculate the number of machines needed for each Operation based on the information below (refer to example in course material and textbook)

Hours per Shift	Uptime	Efficiency	Effective Time per shift	Units per Shift	Takt (min / unit)
8	0.9	0.8	345.6	2500	0.13824

Time Standard in Units per hour
	Body Ends	Shelf Bracket	Body	Cover Ends	Cover Body	Hinge	Tray Ends	Tray Body	Tray Handle
Parts per Unit	2	2	1	2	1	1	2	1	1
Strip Shear	1500	3250	1200	1800	1850	0	3520	1650	0
Chop Shear	850	1100	1075	955	1523	856	1400	1500	0
Punch	834	0	560	780	789	0	0	0	0
Form	650	740	375	525	562	0	750	650	0
Roll Form	0	0	0	0	0	0	0	0	200

Suggestion Build this in Excel and use formulas to calculate. Empty Excel template is provided along with the assignment. But it is not mandatory to use Excel. The final answer should show the number of machines and the calculations used.

2. Given the following parts and routing:

Part Number	Routing (Operation Sequence)
1	R I W D K S
2	R Q I S
3	R I W Q S
4	R W I K Q S
5	R I W K S

a. Create an initial string diagram, and calculate the efficiency.

b. Rearrange the diagram to improve efficiency, and recalculate the new efficiency. Discuss the reasons for the changes you made.

3. For the same parts and routing from problem 2, create a multicolumn process chart for the initial condition, and calculate the efficiency.

4. Given:
   1. Operations Sequence: BCDFPRSW
   2. Part sequence data:

Part	Weight (Importance)	Sequence
1	4	RFDCS
2	3	RCBFS
3	1	RBFCWS
4	2	RDCFBS

Create a FROM-TO Chart.

5. Given a proposed facility which will include the following departments:

a. Create an activity relationship diagram.

b. List and justify your A and X relationships.

Receiving	Inventory Control
Material Storage	Quality Control
Transportation	Assembly
Packaging	Shipping
Security	Maintenance
Welding	Fabrication
Supply Room	Locker Room
Food Service	Training
