Question 6. You are making the inventory decisions for an international company. The product has a forecasted daily demand with mean 365 and standard deviation 36. You have two different options for procuring each product: from your factory in China (out- sourcing) or procuring from your own factory in the United states (in-house). The following table provides the relevant data for each type of procuring. Setup cost Lead time Procurement cost (per unit) Outsourcing $4,500 64 days $4.5 In-house $50 4 days $5 The desired service level (irrespective of the procurement decision) is 97.5% and the cost of capital of the firm is 20% (that is, the firm faces an annual interest rate of 20%). You may assume 365 days in a year. a) If we decide to produce in-house using an (ROP,Q) system. 1. (2 points) What is the optimal ordering quantity? 2x365x365x50 = 3650 tunits Q= 2.

Outsourcing d) (4 points suppose that were that the Mandard deviation of the demand uncertainty is much les tun what we have originally estimated. Will you change your procurement strategy Explain your we The safety stock level is proportional to the standard deviation and touring strategy has a much higher safety stock level compared to the in-house trategy (4:1) As a reven outsourcing strategy has low procurement cost and lower per unit holding.co) (0911), the reduced demand standard deviation would help outsourcing straty more and we should continue outsourde in general, in-house production reserved for high uncertainty item
