- LO3-2, 3-4, 3-5 6. Consider the following production process for manufacturing biscuits. The first step of the process is mixing, where all of the ingredients are combined in the correct proportion to form dough. In the next step of the process, the dough is formed into sheets and cut into pieces in preparation for baking. The cut dough is then baked into biscuits and subsequently must be cooled. The final step of the process is packaging the biscuits for the consumer. The following table summarizes the production process along with the processing times at each step of the process. The process is highly automated, so assume that this is a machine-paced process with one machine available at each step.

An event hall that hosts public lectures, book readings, poetry slams, and other similar events uses a one-week periodic review inventory system for the throat lozenges that it stocks for its patrons. A two-day lead time is needed for any order, and the event hall is willing to tolerate an average of one stock-out per year. (a) Using the event hall's service guideline, what is the probability of a stock-out associated with each replenishment decision? (Round your answer to four decimal places.) (b) What is the replenishment level if demand during the review period plus lead-time period is normally distributed with a mean of 50 units and a standard deviation of 12 units?
