Quantitative Inventory Analysis Assignment Instructions

Overview

The assignment will provide practical knowledge in determining safety stock calculations so that healthcare stock items can be available when needed at the point of service. Hospitals require that their inventory management systems always maintain an optimum safety stock to prevent any stock-outs, which enables the clinical care team to maintain the quality of care and patient satisfaction and to avoid emergency orders of equipment and supplies that are at a high cost. The quantity of the buffer stock that is needed by any hospital system is dependent upon on the lead time to deliver.

Use the Quantitative Inventory Analysis Template for the following problem:

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 do this and wants to use economic order quantity to determine how much to order and when to order. She collects the following information.  St Petersburg College Quantitative Inventory Analysis Questions

Cost of the gloves: $4.00 per box

Carrying costs: 33%, or $__________ per box

Cost of ordering: $150 per order

Lead time: 10 days

Annual demand: 10,000 boxes per year

1. Tab 1 (Basic EOQ/ Economic Order Quantity) What quantity should Abby be ordering?  Prove that your order quantity is “better” than Abby’s by graphing ordering costs, holding costs, and total costs for 1,000, 1,500, and 2,000 boxes.
2. Tab 2 (ROP no SS/ Reorder Point No Safety Stock) How often will Abby need to order? About how many days will there be between orders?
3. Tab 2 (ROP w SS/ Reorder Point No Safety Stock) Assuming that Abby is not worried about safety stock, when should she place this order?
4. Tab 3 (ROP w SS/ Reorder Point with Safety Stock) Abby decides she will be happy if the probability of a stockout is 5 percent. How much safety stock should Abby carry?

Items to include are outlined as follows:

• Length of assignment 1 excel sheet / 3 tabs
  • 1 excel spreadsheet
    • Tab 1 EOQ (Economic Order Quantity)
    • Tab 2 ROP no SS (Reorder Point No Safety Stock)
