Suppose my office uses ten different kinds of inkjet printers, and as a result I need to maintain inventory of ten different types of ink cartridges. This is a large office, and the average demand for each type of cartridge is 15 cartridges per month. My ordering cost is $10.00 per order, and the carrying cost is $2.00 per cartridge per month. What is the optimal order quantity for the inkjet cartridges? (Note, I will need to be maintaining separate inventories and placing orders for each of the ten different types of cartridges. Assume we are using a Q,R system and the different cartridges will be hitting their order points at different points in time.) What is the total annual ordering plus carrying cost of the inventory system, for all ten items? HINT: Find the optimal order quantity and total cost for one of these cartridges. The total cost for all ten types of cartridge is ten times the cost for one.
