Question 1.Consider a four-step serial process with processing times given in the following list. There is one machine at each step of the process, and this is a machine-paced process.

Step 1: 25 minutes per unit

Step 2: 15 minutes per unit

Step 3: 30 minutes per unit

Step 4: 20 minutes per unit

Round your answer to 3 digits after the decimal point if it is not an integer. Do NOT use comma in your numeric answers.

The resource capacity of step 2 is units per hour.

The resource capacity of step 4 is units per hour.

The process capacity is units per hour.

Assume unlimited demand, the cycle time is hours.

Assume that the process starts out empty. It will take hours for the first flow unit to go through an empty system, and it will take a total of hours to complete a batch of 105 units.

Question 2

In a bank there are two bank tellers behind the window. The demand rate is 43 customers per hour. The banks utilization is 90%.

Round your answer to 3 digits after the decimal point if it is not an integer. Do NOT use comma in your numeric answers.

The banks flow rate is customers per hour.

The total capacity of the two bank tellers is customers per hour.

The capacity of one bank teller is customers per hour.

The processing time per customer per bank teller is minutes.
