FACILITIES PLANNING ISE310L SESSION 13 Chapter 14, February 19, 2016 Geza P. Bottlik Page 3 Definitions Cost of Goods Sold – total expenditures to obtain or manufacture the product. This does not include Sales and administrative costs. Safety Inventory – Inventory held to protect against variations in demand and lead time Cycle Inventory – Inventory held to account for lot sizing Landed Cost – Purchase Price plus transportation in Bullwhip effect – accentuation of variations in demand as we go up the chain Replenishment lead time – time from ordering to receipt

Bottlik Page 4 Definitions - continued Quantity Discounts – Price depends on the amount purchased Double Marginalization – Retailer sets price higher than is optimal for the chain in order to have enough margin (Sales are a function of price) Newspaper problem – Deciding how many of a perishable item to order, based on loss of profits (under stocking) and cost of unsold goods (over stocking) Excel Norm functions to calculate normal probabilities: –NORMINV(percentage, mean, standard deviation) = Value –NORMDIST(Value, mean, standard deviation, TRUE) = percentage

Bottlik Page 5 Newspaper problem Newspaper person’s cost = $0.25, no salvage value Profit on a paper = $0.50 Estimated average sales = 60 Estimated standard deviation of sales = 5 Percentage (Service level) = 0.50/( ) =.667 NORMINV(0.667, 60, 5) = 63 or Q= average + z(std. dev) If the overage cost is lower than the shortage cost we order more than the average Underage cost = lost profit = Selling price – Cost Overage cost = Excess unsalvageable inventory = Cost – salvage value Service level = Underage cost/ (Underage + overage cost)
