CASE STUDY - 1

ABC Ltd. has to supply his customers 1000 units of his product per year. Shortages are not allowed and the inventory carrying cost amount to Rs.12 per unit per year. The setup cost per run is Rs.200. Find:

(a) The Economic Order Quantity

(b) The optimum number of orders per year

(c) The optimum period of supply per optimum order

(d) The minimum average yearly cost

(e) The increase in the total cost associated with ordering 25 percent more than EOQ.

CASE STUDY - 2

A supply chain has two members, one buyer and other is seller. The buyer needs 10000 units of an item per year. The buyer’s ordering cost is Rs.450 per order. The buyer’s holding cost is Rs.100 per unit per year. The seller sets up a production run and produces the buyer’s EOQ and dispatches it. His setup cost is Rs.2750. The seller does not hold any inventory. Calculate:

(i) If the two operate independently, what are the buyer’s inventory costs, and

(ii) If they join together and operate as one unit, what will be the total system cost?
