Question

Two types of customers are served by a two-step process with one resource per type. Can you explain how long each customer spends at each resource, and how many resources are used in total?

Answer 1

The average time between two successive arrivals is 2 minutes. It takes 6 minutes on average for three customers to arrive. Each customer spends an average of 2 minutes at each resource, and a total of 2 resources are used in this process.

Step-by-step explanation:

The average time between two successive arrivals can be determined by taking the reciprocal of the arrival rate. Since we expect 30 customers to arrive per hour, the average time between arrivals would be 60/30 = 2 minutes on average.

When the store first opens, we can use the same logic to determine how long it takes for three customers to arrive. Since one customer arrives every two minutes on average, it will take six minutes on average for three customers to arrive.

Therefore, each customer spends an average of two minutes at each resource, and a total of two resources are used in this process.
