(a) Shown below is a system with 5 processes. Details regading this system is shown in the table. A B D >>> >>> >> E A B D B B B Process A B Processing time 265 min/ unit 577 min/ unit 421 min/ unit 234 min/ unit 105 min/ unit D E 18 Num of hours per day Num of days per week 5 (1) Determine the weekly capacity of the entire system. Keep one decimal point for all calculation. Please show calculation steps, as discussed in class, for partial credit (5 marks) (ii) Determine the completion time for the 39th units, if system start empty. Keep two decimal point for all calculation. Please show calculation steps, as discussed in class, for partial credit. (4 marks) With regard to capacity analysis, explain what is Parallel Station Explain why by decreasing number of Parallel Station could decrease capacity of a system. Use the system in question 6a as an example, to support your explanation, by showing the changes in capacity. (9 marks) Kanban Card in a JIT production system "act as a signal". Use a JIT production system with multiple stations as an example to explain the meaning of "act as a signal" clearly. (7 marks) (ii) (b)
