Complete Question:
You are considering the purchase of a new machine to help produce a new product line being introduced. The machine is expected to have a setup time of 10 minutes per batch and a processing time of 2 minutes per part. You plan to have batch sizes of 50 parts. The plant operates 8 hours per day.
What is the capacity of the machine in batches per day?
Answer:
The capacity of the machine in batches = 4 batches per day.
Explanation:
a) Data and Calculations:
Set up time per batch = 10 minutes
Processing time per part = 2 minutes
Batch sizes = 50 parts
Plant operation = 8 hours per day
b) Capacity in batches per day:
Total batch time = 10 + 50 * 2 = 110 minutes
Total minutes of operation per day = 8 * 60 = 480 minutes
Capacity in batches = 480/110 = 4.36 or approximately 4 batches
c) Each batch produces 50 parts with each part taking some 2 minutes and an additional batch setup time of 10 minutes, giving a total of 110 minutes per batch. Since there are some 480 (8 * 60) minutes available per day, it means that the entity can only run about 4 batches (480/110) per day. These 4 batches will consume a total of 440 minutes (110 x 4), leaving some 40 minutes as unutilized time.
An impaired driver refers to someone who is under the influence of alcohol and is driving. If you are sharing the road with such a person, it is safest to drive behind such a person. You can take further action by parking beside the road, note down the vehicle's number and then call the appropriate patrol or emergency to inform them about the driver. This will ensure that such a driver is gotten off the highway.
