First of all, I like you to notice that I have set "Starting WIP" = 4, "mean daily production rate" = 3.5 units per day, and "Maximum Variation around mean" = 2.5 units on all operations in what we call a "Base Model" representing the game played for 20 days (i.e., 4 weeks, 5 days a week). The base model also assumes monthly demand of 70 units (3.5x20days, 4 weeks, 5 days a week). Next, I want you to note the most important feature of this model i.e., it reports results for a single user like you (we call it "1Run") as well as results averaged over 1,000 runs (as if a class of 1,000 students' results are averaged). Now,

1. Click "F9" key few times and observe Average Efficiencies in Panels C and D. Do you see a pattern in the Average Efficiencies of the various operations in Panel C? and D? Describe the pattern you see. In your opinion what causes this pattern?

2. Click "F9" key few times and observe how the measures in Panel E change for “One Run” and “1,000 Runs”. Explain the difference in the way the two sets of numbers change.

3. Finally, Copy and “Paste Special” (using the “values” option) your results from Panel E for “1000 Runs” in the “Base Model” column cells E6 through E18 in the "Scenario Output" worksheet in the Excel model. Explain how your "Base Model" results might be generalized for a more complex production system where parts flow from machine to machine in a wide variety of patterns or routings.
