Chapter D, Problem 3P
Question
• D.3 Paul Fenster owns and manages a chili-dog and soft-drink stand near the Kean U. campus. While Paul can service 30 customers per hour on the average (μ), he gets only 20 customers per hour (λ). Because Paul could wait on 50% more customers than actually visit his stand, it doesn’t make sense to him that he should have any waiting lines.
Paul hires you to examine the situation and to determine some characteristics of his queue. After looking into the problem, you find it fallows the six conditions for a single-server waiting line (as seen in Model A). What are your findings?

The Donald Fertilizer Company produces industrial chemical fertilizers. The projected manufacturing requirements (in gallons) for the next four quarters are 60,000,
90,000, 90,000, and 140,000 respectively. A level workforce is desired, relying only on anticipation inventory as a supply option. Stockouts and backorders are to
be avoided, as are overtime and undertime.

year. Beginning inventory is 0.
The quarterly production rate is ☐ gallons. (Enter your response as an integer.)
How would you design an operations plan and schedule for a new product/service?
What factors would you consider and what challenges would you anticipate?
Why are these factors and challenges relevant and how would you address them?
