1. 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
2. You are designing a process for the assembly of a consumer electronics product with a labor content of nine minutes. You are trying to decide whether to use (1) a single machine-paced line with eight workers or (2) eight separate single-worker cells. Each of the eight single-operator cells would perform exactly the same collection of assembly tasks as the single line, using the same tools, technologies and equipment. On the assembly line, each worker would be assigned to a single assembly task.
Which approach would produce the greater output?
the eight cells
There is no difference in skill requirements between the single line and the eight cells.
Additional information is needed to determine the greater output.
the single line
