Question 3:
A catering company must have the following number of clean napkins available at the beginning of each of the next four days: day 1: 15, day 2: 12, day 3: 18, and day 4: 6. After being used, a napkin can be cleaned by one of two methods: fast service or slow service. Fast service costs $0.10 per napkin, and a napkin cleaned via fast service is available for use the day after it is last used. Slow service costs $0.06 per napkin, and a napkin cleaned via slow service is available two days after they were last used. New napkins can be purchased for a cost of $0.20 per napkin.
Part A: Formulate the problem as a minimum cost transportation problem.
Part B: Use Excel Solver to solve the problem (provide exact values for all variables and the optimal objective function).
Question one:
Suppose a radiology department uses FCFS to determine how to sequence patient x-rays. Assuming these data are
representative, compare between FCFS and other scheduling rules should the radiology department be using and why
