Due to a product upgrade, two new operations are need for thenew version of the part mentioned in Practice Problem 1. Operation3 is a high-precision drilling operation. Machine 3 has a mean timeto fail of 10 hours and a mean time to repair of 45 minutes.Machine 4 paints the part pink1. Its mean time to fail is 100 hoursand its mean time to repair is 6 hours. The operation times ofMachines 3 and 4 are 2 minutes.
When the line is rebuilt there may be buffers between themachines. As the manufacturing systems engineer, your job is todecide whether buffers are needed. (It will also be to decide whatsize the buffers should be, but that issue is treated in the secondpart of this course.)
Part 1
What is the maximum production rate that the line can achievewith-out buffers in parts per minute? Round to 4 decimalplaces. unanswered
Part 2
What is the maximum production rate that the line can achievewith buffers in parts per minute? Round to 4 decimal places. Hint:Maximum production rate can be achieved with infinitebuffers unanswered
Part 3
At what rate does material accumulate in the line if it hasinfinite buffers in terms of parts per minute? Round to 4 decimalplaces.
