1. The Samsung company carries a variety of electronic inventory items. For the LED TV the daily demand is normally distributed with a mean of 125 units, standard deviation of 30 and lead time is 16 days. Samsung wants to maintain 95% service level. What is the reorder point and how much safety stock should be carried?

2.Four warehouse are supplied by four factories. The supply available from each factory, the demand at each warehouse and the cost per unit of transporting goods from the factories to the ware houses are summarized in the following table. Find the initial basic feasible solution using North West corner rule.

Ware house

E F G H Supply

A 10 30 25 15 14

Factory B 20 15 20 10 10

C 10 30 20 20 15

D 30 40 35 45 12

Demand 10 15 12 15

3. Samsung company sells Television other manufactures, reduce the inventory cost by determining the optimal number of Television to obtain per order. The order demand is 1000 units, the order cost is SR10 per order and the average carrying cost per unit per year is SR 0.50. If the EOQ assumptions are met

Then calculate the optimum number of units per order. If the ordering cost of each order increased by a factor 4 , then also determine the sensitivity analysis .
