5. - 7. Little's Law: Flow Rate 3 points possible (graded) 5. Which of the following clearly defines the Flow Rate (R) of a process? The time taken for a flow unit to go from the beginning to the end of the process The number of flow units in the process at a given moment in time The number of flow units going through the process per unit of time 6. A paper mill has on average 7200 quires of paper in production at any particular time (I = 7200). (A quire of paper is a measure of paper quantity. The usual meaning is 25 sheets of the same size and quality: 20 of a ream of 500 sheets.) A quire takes 40 minutes of paper production and 20 minutes for final packaging. How many quires of paper does the paper mill produces per minute (include the packaging as part of the total production flow)? (The answer are in quires/minute not per hour!) 120 quires/min 50 quires/min 5 quires/min 2 quires/min 7. The paper mill wants to improve its production. The mill has installed new machines, which reduces the production time by 20%, and has hired, more employees, which reduces the packaging time by 30%. The mill still has on average 7200 quires of paper in production at any particular time. What is the new number of quires that the paper mill can produce per minute? 2.61 quires/min 5 quires/min 156 quires/min the rate stays the same
