Given Data, For Supplier A, [ Ch] Holding Cost = 20% of the Unit Cost per unit per Year, [Co ]Ordering Cost = USD 150 Per Order, [ D ]Annual Demand = 10,000 Units Item cost could vary as per the table data, Considering each Item cost, if we calculate Optimal order quantity, then the result will fall in between 0 to 2,999, thus let me consider, for any order in between 0 to 2,999, Price will come USD10 per unit, |
For Supplier A, Formula for Optimal Order Quantity = Square Root of [( 2 X D X Co)/ Ch], Or, Optimal Order Quantity = Square Root of [ ( Or, Optimal Order Quantity = Square Root of [ 15,000,00] = 1224.74 = 1225 Units, So, for the Optimal order quantity 1225 Units, Firm should pay the price per unit = USD 10 per unit, Number of Order = Annual Demand / Optimal Order Quantity Or, Number of Order = 10,000 / 1225 = 8.16 Orders Total Annual Ordering Cost = Number of Order X Ordering Cost per Order = 8.16 X USD 150= USD 1224.489 = USD 1224.50 Total Annual Holding Cost = Average Units X Holding Cost per unit per Year Or, Total Annual Holding Cost = (1225/2) X USD (0.20 X 10) = USD 1225 Total Annual Purchasing Cost = Order Quantity X Number of Order X Purchase cost per Unit = 1225 * 8.16* USD 10 = USD 132,486.624 Total Annual Cost = Total Annual Ordering Cost + Total Annual Holding Cost + Total Annual Purchasing Cost = USD 1,00,000 Or, Total Annual Cost at the Optimal Behavior = USD 1224.50 + USD 1225 + USD 1,00,000= USD 102449.5 |
Given Data, For Supplier B, [ Ch] Holding Cost = 20% of the Unit Cost per unit per Year, [Co ]Ordering Cost = USD 150 Per Order, [ D ]Annual Demand = 10,000 Units Item cost could vary as per the table data, Considering each Item cost, if we calculate Optimal order quantity, then the result will fall in between 0 to 3,999, thus let me consider, for any order in between 0 to 3,999, Price will come USD11 per unit, |
For Supplier B, Formula for Optimal Order Quantity = Square Root of [( 2 X D X Co)/ Ch], Or, Optimal Order Quantity = Square Root of [ ( Or, Optimal Order Quantity = Square Root of [ 1363636] = 1167.748 = 1168 Units, So, for the Optimal order quantity 1168 Units, Firm should pay the price per unit = USD 11 per unit, Number of Order = Annual Demand / Optimal Order Quantity Or, Number of Order = 10,000 / 1168 = 8.56 Orders Total Annual Ordering Cost = Number of Order X Ordering Cost per Order = 8.56 X USD 150= USD 1224.489 = USD 1284.247 = USD 1284.25 Total Annual Holding Cost = Average Units X Holding Cost per unit per Year Or, Total Annual Holding Cost = (1168/2) X USD (0.20 X 11) = USD 1284.8 Total Annual Purchasing Cost = Order Quantity X Number of Order X Purchase cost per Unit = 1168 * 8.56* USD 11 = USD 11,0000 Total Annual Cost = Total Annual Ordering Cost + Total Annual Holding Cost + Total Annual Purchasing Cost Or, Total Annual Cost at the Optimal Behavior = USD 1284.25 + USD 1284.8 + USD 110000= USD 112569, |
