(a)

Shown below is a system with 5 processes. Details regading this system is shown in the table.

	A	>>>	B	>>>	C	>>>	D	>>>	E
	A		B				D		E
									E

Process	Processing time
A	960 min/ unit
B	850 min/ unit
C	460 min/ unit
D	720 min/ unit
E	1050 min/ unit
Num of hours per day	18
Num of days per week	7

(i)

Determine the weekly capacity of the entire system. Please show calculation steps for partial credit.

(5 marks)

(ii)

Determine the completion time for the 35th unit if system start empty. Please show calculation steps for partial credit.

(6 marks)

(iii)

Redraw the system above so that it has exactly 2 bottleneck processes

Redraw means;

1. You can add or subtract number of parallel station for each process
2. You are not allowed to add any new process
3. You are not allowed to change any processing time

(7 marks)

(b)	Identify and discuss ONE (1) impact of Global Warming which deem disastrous toward mankind.
