6. You purchase and manage the raw material inventory for an assembly plant. You have a particular component that goes into a final assembly that you need to purchase. You have 5 bids in front of you from different suppliers for this component. Here are the bids with some of your estimates: Landed Price Lead Time (weeks) Lead Time Std Dev Order Freq (weekly) Supplier 1- US Supplier 2- US Supplier 3- Mexico Supplier 4- China Supplier 5- China $100 $99 $85 $80 $75 4 4 8 16 20 2 3 5 5 2 2 4 4 0 1 Landed price is the total price to get the product to your facility. You have estimated the Lead Time Std Dev based on your experience with these suppliers and their country of origin. Order Freq specifies how frequently you place orders. 1 = weekly, 2 = every other week, and 4 = once every 4 weeks. Since the demand and assembly schedule is variable, you need to protect yourself with safety stock. Your accounting department determined that the cost of carrying inventory is 12% of the cost of the product. You want to maintain a cycle service level of 99% to ensure that you keep the assembly operations running. When the assembly department requests an item, you are expected to deliver it immediately. The estimated demand for this component is 100 units per week with a standard deviation of 25. You are expected to need this item for at least a year and maybe more. However, there is a chance that it could get discontinued with very little notice (demand change or engineering change). For each supplier, determine the total purchase cost, total inventory cost, and inventory turns. Select what you think are the 2-3 best options and present a few bullet points for the pros and cons of going with each of those. This list should be meant to help a decision-maker make the final choice.
