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 20 minutes per batch and a processing time of 1.5 minutes per part. You plan to have batch sizes of 60 parts. The plant operates 8 hours per day.
Draw a Gantt Chart for the process.
i. Show the Cycle times
ii. Show the MTT
What is the capacity of the machine in batches per day?
What is the capacity of the machine in parts per day?
How many batches per day can you run through the machine if you plan to operate the machine at a 75% utilization rate?
How many parts per day can you process through the machine if you plan to operate the machine at an 80% utilization rate?
You have a machine that is staffed 8 hours per day. The average throughput rate is 28 batches per day, and the setup time is 5 minutes per batch. The plant operates 16 hours per day.
