Using linear programming techniques, MaxProfitCalc calculates the maximum profit solution for shipping products located in three separate locations to five customers with different profit margins for each location/customer combination. Profit margins for customers are entered in the system along with customer demand and available product supply. In addition to quickly calculating the maximum profit and quantities matrix, MaxProfitCalc provides the first iteration of the North West Corner method along with the Least Cost Cell method for comparative purposes. Five detailed iterations are available to show the steps required to achieve the maximum profit solution. An example problem and solution are included to assist with understanding system operation.
