PPT 13-12
Buffer Stock
We need it so we won’t loose sales, complementary sales, and customers
Buffer stock is dependent on:
-Forecast interval variance (Forecast interval = lead time + review time)
-Variation in Demand (actual demand - forecasted demand)
-Time to Get Product from Supplier
-Time to Get Product from Distribution Center
- Product availability requested of IM systems
PPT 13-13
Forecasting Demand
Forecasting -- extrapolating the past into future using statistical and mathematical methods
Objectives:
– Ignore random fluctuations in demand
– But be responsive to real change
PPT 13-14
Forecasting Sales
• Tradeoff Recent Sales Against Past History of Sales
– Recognize Recent Trends, But Don’t Over Weight Recent Experience
• Exponential Smoothing
Old = Old + ά x (Recent – Old) Forecast Forecast Demand Forecast
84 = 96 + .5 x (72 – 96)
• ά ranges for 0 to 1
– Higher ά Weighs Recent Sales More
PPT 13-15
Order Point
• Order point = the point at which inventory available should not go below or else we will run out of stock before the next order arrives.
• Assume Lead time = 0, Order point = 0
• Assume Lead time = 3 weeks, review time = 1 week, demand = 100 units per week
• Order point = demand (lead time + review time) + buffer stock
• Order point = 100 (3+1) = 400
PPT 13-16
Order Point continued
• Assume Buffer stock = 50 units, then
• Order point = 100 (3+1) + 50 = 450
• We will order something when order point gets below 450 units.
PPT 13-17
Calculating the Order Point
Order Point = (Demand/Day) x (Lead Time +Review Time) + Backup Stock
167 units = (7 units x (14 + 7 days) + 20 units
So Buyer Places Order When Inventory in Stock Drops Below 167 units
PPT 13-18
Merchandise Budget Plan
• Plan for the financial aspects of a merchandise category
• Specifies how much money can be spent each month to achieve the sales, margin, inventory turnover, and GMROI objectives.
• Not a complete buying plan--doesn’t indicate what specific SKUs to buy or in what quantities.
PPT 13-19
Six-Month Merchandise Budget Plan for Men’s Tailored Suits
PPT 13-20
Steps in Preparing Plan
• Forecast Six Month Sales for Category
• Breakdown Total Sales Forecast into Forecast for each Month (lines 1, 2)
• Plan Reductions for Each Month (lines 3, 4)
• Determine Beginning of the Month (BOM) Stock to Sales Ratio (line 5)
• Calculate BOM Inventory (line 6)
• Calculate EOM Inventory (line 7)
• Calculate Monthly Additions to Stock (line 8)
PPT 13-21
Open to Buy
• Monitors Merchandise Flow
• Determines How Much Was Spent and How Much is Left to Spend
PPT 13-22
Six Month Open to Buy
PPT 13-23
Open-to-buy for Past Periods
• Projected EOM stock = actual EOM stock
• Open-to-buy = 0
• There is no point in buying merchandise for a month that is already over.
PPT 13-24
Open-to-Buy for Current Period (I)
• Projected EOM stock =
• Actual BOM stock
• + Actual monthly additions to stock (what was actually received)
• + Actual on order (what is on order for the month)
• - Plan monthly sales
• - Plan reductions for the month
PPT 13-25
Open-to-Buy for Current Period (II)
• Open-to-buy =
• Planned EOM stock (from merchandise budget plan)
– Projected EOM stock (based on what is really happening)
PPT 13-26

Retail Inventory Method (RIM)
Two Objectives:
– To maintain a perpetual or book inventory of retail dollar amounts.
– To maintain records that make it possible to determine the cost value of the inventory at any time without taking a physical inventory.
PPT 13-36
Advantages of RIM
• The retailer doesn't have to “cost” each time.
• Follows the accepted accounting practice of valuing assets at cost or market, whichever is lower.
PPT 13-37
Advantages of RIM cont’d
• Amounts and percentages of initial markups, additional markups, markdowns, and shrinkage can be compared with historical records or industry norms.
• Useful for determining shrinkage.
• Can be used in an insurance claim case of a loss.
PPT 13-38
Disadvantages of RIM
• System that uses average markup.
• Record keeping process involved is burdensome.
PPT 13-39
Steps in RIM
Calculate Total Merchandise Handled at Cost and Retail
Calculate Retail Reductions
Calculate Cumulative Markup and Cost Multiplier
Determine Book Inventory at Cost and Retail
PPT 13-40
Retail Inventory Method
Cumulative Markon = (total retail - total cost) / total retail: ($290,000 - $160,000) / $290,000 = 44.8%
The Cost Multiplier = cumulative markon (100% - cumulative markon%) = 55.2%
Ending book = total goods handled at retail - totalinventory at retail reductions: $290,000 - $208,000 = $82,000
Ending book = ending book inventory at retail x costinventory at cost multiplier: $82,000 x 55.2% = 45,264
PPT 13-41
