A company has estimated the demands for a particular part as follows: The cost per setup (order) is $50, and the inventory holding cost is $5 per unit per period. There are currently no parts available in inventory. Suppose that the maximum number of units that can be stored in the warehouse is 75 . Apply the two-stage heuristic approach to obtain a solution to this capacitated lot sizing problem and calculate the sum of the total setup and total holding costs for the solution
