Question

The Credit Card Processing unit of a bank receives 60 applications per hour. All applications first go through application processing that takes 6 minutes per application. There are 4 workers in the unit who process the applications. After the application is processed, all applications go through the credit check stage which takes 10 minutes per application. There are 6 workers at this stage. 20% of the applications fail the credit check and are rejected. Remaining 80% of applications that pass the credit check are sent for determining credit limit. There are 6 workers at the Determine credit limit stage, and it takes 15 minutes for a worker to process one application. After the credit limit is determined, all applications are sent to the issuing desk, who issue the credit card, and it takes 3 minutes per application.
What is the capacity of the "Credit Check" stage in number of applications per hour?

Answer 1

Answer:

36 applications/hour

Explanation:

Number of application/hour/worker = 60/processing time

Number of application/hour = (60/processing time) * Number of workers

Process     No of      Processing  Number of application  Number of

                  Workers   Time (min)   /hour/worker                application/hour

Application     4                 6                   10                                   40

Processing

Credit Check  6                10                   6                                    36

Determine      6                 15                   4                                    24

Credit Limit

Issue Card      2                 2                   30                                   60

Capacity of credit check in applications per hours = 36 applications/hour
