2. (The Buffer Overflow Model) Your task is to simulate and animate a model of two machine groups: The First Machine group and The Overflow Machine group. In this system, parts arrive at a rate of 6 per hour (one every exponential time with mean 10 minutes) and have a constant processing time of 9.9 minutes (deterministic processing time). The First Machine group has a buffer space for 2 jobs in queue only (so only up to 2 jobs can wait in queue). New jobs are sent to the First Machine group as long as there is an available buffer space in queue. Otherwise, it is sent to the Overflow Machine group with constant processing time of 19 minutes. (a) Make an initial model with infinite queue and run 1 replication of run length 1000 minutes. (b) Calculate steady-state utilization analytically for the initial model and compare the utiliza- tions from your simulation results. Do they match? (c) Now revise your initial model for the Buffer Overflow Model. Add a plot for the number of customers waiting in queue for the First Machine group. (d) Report the expected total system time for jobs processed at the First Machine group and at the Overflow Machine group based on 100 replications, respectively. In addition, estimate $w_q, l_q, \rho$ for each machine group and report their 95% confidence intervals based on the 100 replications. (e) Now suppose that there is an inspection station and 10% of jobs are sent to a machine group (either the First Machine group or the Overflow Machine group). Each job is allowed to go through processing only up to 2 times. Change entity picture for the returning job and report total system time for the jobs which went through processing 2 times and salvaged.

1. The right to make decisions about one's own life is the principle of autonomy. 2. In Bentham's calculus, the criterion of how many people are likely to benefit from a course of action is called utility. 3. A moral proposition of the form "If you want X, then you should do Y" is called a hypothetical imperative. 4. The idea that moral judgments are expressions of feelings is called emotivism. 5. Metaethics is concerned with the meaning of ethical terms. 6. For Beauchamp and Childress, principles are the locus of certainty; for casuists, the locus of certainty is cases. 7. In Bentham's calculus, the criterion of how many people are likely to benefit from a course of action is called utility. 8. To answer the objections that utilitarianism may command to do something that is unjust, utilitarians adopt one of two strategies: a. 9. A prima facie duty becomes an actual duty in two circumstances: c. 10. For Kant, the only thing that is good without qualification is goodwill.
