Final answer:
The critical ratio scheduling rule helps determine the sequence in which jobs should be processed based on their due dates and processing times. However, without the specific due dates and processing times of the jobs waiting to be processed, it is not possible to determine the sequence using this rule.
Step-by-step explanation:
The critical ratio scheduling rule helps determine the sequence in which jobs should be processed based on their due dates and processing times. The critical ratio is calculated by dividing the time until the due date by the processing time. The job with the lowest critical ratio should be processed first.
In this case, we need the due dates and processing times of the jobs waiting to be processed at the machining centre. Without that information, it is not possible to determine the sequence using the critical ratio scheduling rule.
In order to provide a specific answer, we would need more information about the due dates and processing times of the jobs waiting to be processed.
