Position 2 In the LP vaccination program example, analyze the situation if the probability of a flu outbreak is only 65 percent and the cost of the vaccination program is $8 million.
Once you review the workbook IR C6 Problem 1 Decision Tree.xls and corresponding worksheets, what would your decision be in this case? Make sure to include rationale and justification for your position/decision. Application 3 Patient satisfaction ratings are commonly used as 1 piece of operations management data to determine if quality outcomes are improving (i.e., process changes/improvements are working) or not improving (i.e., process changes/improvements are not working and need to be modified). Using the attached Excel file Healthcare Satisfaction.xls, (data is averaged on a Likert type scale from 0 = strongly dissatisfied, 1 = dissatisfied, 2 = satisfied, 3 = extremely satisfied) analyze the data as follows: 1. List the range of 2010 and 2013 ratings. 2. List the standard deviation of 2010 and 2013 ratings. 3. List the averages associated with 2010 and 2013 ratings. 4. Construct a bar graph showing the differences between average 2010 and 2013 ratings. 5. Complete a paired comparison t test (Click on Data Tab, Data Analysis may need to install Analysis ToolPak add-in, see F1 help for specific instructions). 6. Based on the P value of the t test results, is there a statistically significant difference/improvement? Is there a practical difference/improvement? 7. In summary, is the quality improvement program working, or does it need process modifications. Why or why not? Application 4 The hematology lab manager has been receiving complaints that the turnaround time for blood tests is too long. Data from the past month show that the arrival rate of blood samples to one technician in the lab is five per hour and the service rate is six per hour. Given the 83.3% capacity utilization rate, what would you propose to change related to operations management processes to improve the efficiency? List 3 specific strategies with rationale and justification. Position 5 Hospital purchasing agent Abby Smith needs to order examination gloves for the hospital. Currently, she orders 1,000 boxes of gloves whenever she thinks there is a need. Abby has heard that there is a better way to make this purchase and wants to use economic order quantity (EOQ) to determine how much to order and when to order. She collects the following information. Cost of the gloves: $4.00/box Carrying costs: 33% or $1.33/box Cost of ordering: $150/order Lead time: 10 days Annual demand: 10,000 boxes/year Using the Excel workbook IR C13 Problem 2 Inventory Analysis.xls answer the following questions: a. What quantity should Abby be ordering? Prove that your order quantity is better than Abbys by graphing ordering costs, holding costs, and total costs for 1,000, 1,500, and 2,000 boxes. b. How often will Abby need to order? About how many days will there be between orders? c. Assuming that Abby is not worried about safety stock, when should she place an order? d. Abby decides she will be satisfied if the probability of a stockout is 5 percent. How much safety stock should Abby carry? e. If Abby were to set up a two-bin system for gloves, how many boxes of gloves would be in each bin? Application 5 Two nurses (Mary and Jane) at the Riverview UCC have decided to work part time. They would like to work only two (consecutive) days per week. Because they would be part-time employees, their salary and benefits per nurse day would be reduced to $160 on weekdays and $220 on weekend days. Riverview could hire an additional full-time nurse if needed. Should Riverview agree to this request? If it does, will it need to hire additional nurses?
