An Assembly Line with 28 Operations Is to Be Balanced

question 30

Multiple Choice

An assembly line with 28 operations is to be balanced. The total amount of time required for all 28 operations is 39 minutes. The longest operation takes 2.2 minutes and the shortest takes 0.8 minutes. The line will operate for 450 minutes per day.
1) Determine the minimum and maximum cycle time.
2) What is the output rate if the cycle time is set at 2.2 minutes?

• A)min cycle time = 0.8; max cycle time = 39; output rate = 204.5
• B)min cycle time = 2.2; max cycle time = 39; output rate = 204.5
• C)min cycle time = 2.2; max cycle time = 31.2; output rate = 562.5
• D)min cycle time = 0.8; max cycle time = 2.2; output rate = 562.5
