Peach Electronics wants your team to investigate improvements to one of its electronic component manufacturing processes. Components arrive at this process from two other plants. They arrive pre-assembled as either Component 602A or Component 917AT. Each component will arrive separately so, initially, there are two separate process lines until the Burn-In station where they will combine. Component 602A arrives in batches of 4. The time between arrivals is described as triangularly distributed with a minimum of 10 minutes, a mode of 25 minutes, and a maximum of 30 minutes.

The Component 917AT produces batches of 8 with an interarrival time described as triangularly distributed with minimum of 10 minutes, a mode of 25 minutes, and maximum of 50 minutes between batches. Once they arrive at the receiving dock, the components go through an involved testing procedure and a burn-in operation before they are packaged and shipped. At the test station, you will require a test person to operate each test machine.

Testers are cross-trained to work on either the 602A or the 917AT test station. Initial testing time at the separate test stations for a 602A component is exponentially distributed with a mean of 10 minutes and for 917AT it is uniformly distributed with minimum and maximum values of 15 and 25 minutes. All components are tested where historically, 14% of all units will fail and require rework. Testing of 602A and 917AT should be prioritized by highest attribute value. Rework is accomplished by a rework person at separate 602A and 917AT rework stations where units are typically processed on a FIFO basis. Reworkers are also cross-trained to work either station. Rework for 602A's can be done at a constant rate of 1 hour and 917AT's at a rate of 2 per hour. A reworked component requires testing again so all reworked components return to the testing queue where it has priority over non-reworked units.

A unit can fail multiple times and be reworked multiple times. Rework of 602A and 917AT should be prioritized by first in, first out. Once a component passes testing, it is ready for burn-in. Burn-in causes the component to be exercised for a period of 1.5 hours for 602A's and 2.0 hours for 917AT's. Burn-in is done on a large rack machine where the component is automatically plugged in (no worker needed). This rack machine will allow up to 60 units to be burned-in simultaneously. Historically, 97% of all units pass the burn-in and go on to final packaging. 3% fail and are trashed. Final packaging requires a packager worker where labeling and boxing are done.

This job is normally distributed with a mean of 8 minutes, standard deviation of 2.3 minutes. Create a failure distribution with the following parameter values: Uptime ~Norm(mean = 85.1, std. deviation = 0.45) hours and Downtime ~ Weib(Beta = 1.3, Alpha = 2.1) hours. Run the simulation for 160 hours at 8 hrs/day and make appropriate recommendations to this company given the following information: - The selling price of the finished components are: - $100 for each good 602A board and $125 for each good 917AT board as final packaged units. - Personnel costs are: - Test Technician makes $22.00 per hour - Rework Technician makes $15.00 per hour - Final Packaging Worker makes $10.00 per hour - Reworked material costs are $25.00 per unit reworked. - Trashed components cost $20.00 per unit trashed (after burn-in). - You cannot have more than 25 test stations because it's too expensive. Your objective is to maximize the net profit (totalprofit$-laborcost$-reworked$-trashed$). Change your resource numbers to help you maximize your net profit.
