1) Develop an inventory system to help Ali to examine all the scenarios for each of the seven alternatives, and then select the best scenario that minimize the Total inventory costs. You can help him to find how much to order and when to order to meet customer demand in order to minimize the total inventory costs. a. Which scenario gives the minimum AH? b. Which scenario gives the minimum AO? c. Which scenario gives the minimum CC? d. Which scenario is the best, that minimizes the total inventory costs? Why? e. Apply the solver to find the number of orders that minimizes combined cost. knowing that number of orders should be between 1 and 52. 2) Develop EOQ model to find the optimal value of quantity each order, optimal combined cost, and optimal number of orders per year. 3) Suppose that Ali decided to go for best policy, he wants to know what happens to combined cost if the following parameters change? a. What if the ordering cost changes? If the ordering cost goes up by $3? b. What if the ordering cost changes? if the ordering cost goes up 20%? c. What if holding cost changes by a factor of F"20% increase"? d. What if the ordering cost changes by a factor of K "20% increase"? 1) Develop an inventory system to help Ali to examine all the scenarios for each of the seven alternatives, and then select the best scenario that minimize the Total inventory costs.
