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

Recently, you learned that several employees have punching each other's time cards to avoid be counted as late. The times vary but range from 10 minutes to 30 minutes in terms of "clock" time. Given the service-focused center, attendance and timeliness are essential to meet customer expectations. Many of the employees are aware of this practice and have considered it acceptable and you overhead employees asking each other to punch their time clock. In some instances, the employees leave early without clocking out and their associates sign them out at the end of the shift.

Different departments use this information. For instance, the production process uses this information to forecast the expected sale for next month. The production clerk uses this to create an online production schedule. From this schedule, the system automatically prepares weekly online work orders to be used by the production department. The production supervisor assesses the work orders from his terminal and prepares the necessary paper based move tickets and materials requisitions. Then, the move tickets and two copies of the materials requisitions are distributed to each work centre. Later, work center employees submit the two copies of the materials requisitions to the warehouse in exchange for materials and sub-assemblies. If additional new materials are needed beyond the standard quantity, the supervisor issues additional materials requisitions. Work centre employees record their work hours on…arrow_forward
