●
Inventory Turnover Ratio or Inventory Turns
– = Cost of Goods Sold / Average Inventory (over a certain period)
●
Periods(days/weeks/months) of Inventory
– = Average Inventory / Cost of Goods Sold
●
Inventory Turnover is the reciprocal of Periods of Inventory

Solution
●
Inventory Turnover Ratio or Inventory Turns
– = Cost of Goods Sold / Average Inventory (over a
certain period) = 1/1.5 = 66.7%
●
Periods(days/weeks/months) of Inventory
– = Average Inventory / Cost of Goods Sold = 1.5/1 =
150%

The simplest case
●
Demand is known with certainty
●
Demand (D) is constant
●
Order is received instantaneously
Supply Chain Management
Mohammad Tawfik
#AcademyOfKnowledge
http://SCM.AcademyOfKnowledge.org
Ordering
●
Order Cost = Number of
Orders * (Shipping Cost +
Ordering Cost + Receiving
Cost)
●
Inventory Cost = Holding
Cost * Average Inventory +
Storage Cost
Supply Chain Management
Mohammad Tawfik
#AcademyOfKnowledge
http://SCM.AcademyOfKnowledge.org
Ordering
●
Total Cost = C*D/Q + H*Q/2 + S
●
To minimize cost, differentiate and equate by
zero
●
Q(optimum) = sqrt(2*D*C/H)
Supply Chain Management

Practical Considerations
●
Difficult to accurately assess costs
●
Suppliers insist on minimum order quantities
●
Suppliers only supply in package quantity

  • 2. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Inventory Inventory
  • 3. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org What are Inventories? ● Inventories are goods or materials that are in any stage of readiness that are being held for future sale
  • 4. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Reasons for Inventories ● Transactional efficiency ● Speculation ● Hedging
  • 5. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Types of Inventories ● Based on stage of completion – Raw material – Work-In-Process – Finished goods
  • 6. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Types of Inventories ● Based on reason for keeping – Cycle inventory due to batching – Anticipation inventory for seasonality – Safety stock to buffer against uncertainty – Pipeline inventory that is on-order or in-transit – Strategic inventory to position for better negotiation
  • 7. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Inventory Inventory Management Management
  • 8. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Back to Zeco :)
  • 9. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org
  • 10. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org What inventory does Zeco have?
  • 11. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org The most important question that YOU need to answer is: WHY do I need inventory? WHY do I need inventory?
  • 12. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org The motive for inventory: ● Transaction motive Transaction motive: Economies of scale is achieved when the number of set-ups are reduced or the number of transactions are minimized. Donglei Du
  • 13. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Imagine having to buy sugar 10 times a day each for 1 kg!
  • 14. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org The motive for inventory: ● Precautionary motive Precautionary motive: hedge against uncertainty, including demand uncertainty, supply uncertainty Donglei Du
  • 15. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org What if you get to buy sugar, and your supplier is out of it!!!
  • 16. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Or worse … Customer have to wait until you purchase the sugar each time a cup of coffee is ordered!!!
  • 17. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org The motive for inventory: ● Speculative motive Speculative motive: hedge against price increases in materials or labour Donglei Du
  • 18. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Imagine having to say: “Sorry sir, but the coffee price have changed because the sugar price went up an hour ago”
  • 19. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org What is the purpose of inventory management?
  • 20. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Purpose of Inventory Management ● The objective of inventory is to achieve satisfactory levels of customer service while keeping inventory costs within reasonable inventory costs within reasonable bounds bounds. Donglei Du
  • 21. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Purpose of Inventory Management ● Level of customer service: – (1) in-stock rate ”Yes sir, coming right-away” ”Yes sir, coming right-away” – (2) number of back orders ”Sorry sir, you need to wait until we buy the sugar” ”Sorry sir, you need to wait until we buy the sugar” – (3) inventory turnover rate: the ratio of average cost of goods sold to average inventory investment ”Since we use sugar all the time, let’s build a sugar factory” ”Since we use sugar all the time, let’s build a sugar factory” Donglei Du
  • 22. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Purpose of Inventory Management ● Inventory cost: cost cost of ordering ordering and carrying carrying trade-off Donglei Du
  • 23. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Inventory Metrics ● Macro level metrics ● Inventory Turnover Ratio or Inventory Turns – = Cost of Goods Sold / Average Inventory (over a certain period) ● Periods(days/weeks/months) of Inventory – = Average Inventory / Cost of Goods Sold ● Inventory Turnover is the reciprocal of Periods of Inventory
  • 24. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Example ● To make sure that he never runs out of stock, Zeco decided to keep 1 day-worth of supplies, all the time, in the store. ● What is the inventory turnover ratio of Zeco cafe?
  • 25. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org
  • 26. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Solution ● Inventory Turnover Ratio or Inventory Turns – = Cost of Goods Sold / Average Inventory (over a certain period) = 1/1.5 = 66.7% ● Periods(days/weeks/months) of Inventory – = Average Inventory / Cost of Goods Sold = 1.5/1 = 150%
  • 27. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Question! ● In the case of Zeco Cafe, can the average inventory become zero? ● If yes, how? ● If no, what is the minimum average inventory period in any given period?
  • 28. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Order Quantity
  • 29. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Inventory Related Costs ● Transaction costs for each order – Ordering – Receiving – Costs of transporting
  • 30. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Inventory Related Costs ● Holding costs (depend on how much average inventory) – Storage costs – Cost of working capital
  • 31. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Economic Order Quantity
  • 32. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org The simplest case ● Demand is known with certainty ● Demand (D) is constant ● Order is received instantaneously
  • 33. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Ordering ● Order Cost = Number of Orders * (Shipping Cost + Ordering Cost + Receiving Cost) ● Inventory Cost = Holding Cost * Average Inventory + Storage Cost
  • 34. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Ordering ● Total Cost = C*D/Q + H*Q/2 + S ● To minimize cost, differentiate and equate by zero ● Q(optimum) = sqrt(2*D*C/H)
  • 35. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Practical Considerations ● Difficult to accurately assess costs ● Suppliers insist on minimum order quantities ● Suppliers only supply in package quantity
  • 36. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org Assignment #3 Assignment #3
  • 37. Supply Chain Management Mohammad Tawfik #AcademyOfKnowledge http://SCM.AcademyOfKnowledge.org AlYomn Steel Sales ● According to the demand data provided in the spreadsheet: – What is the average monthly demand? – What is the standard deviation in the monthly demand? – If the transportation cost is LE2400, the cost of working capital is 15% annual returns, warehouse cost is free, receiving cost LE250. What would the optimum ordering quantity be? – If the steel is subject to deterioration rate of 1% per month, how much would the optimum ordering quantity be? – Download the data spreadsheet from this link
