- The constraints and objective function in linear form:

- Define the meaning of each variable

- Explain the purpose of the constraints

 How would one formulate a linear program that minimizes the total cost for DEF over the months of January through March?

For the months of January and March, costs and demands are as follows January unit production costs capacities Plant 1 47 Plant 2 51 February unit production costs Plant 1 50 Plant 2 53 March Plant 1 Plant 2 unit production costs 57 55 January Market 6 Market 7 February Market 6 Market 7 March Market 6 Market 7 January February Warehouse 4 Warehouse 5 - demand 850 750 February - March Warehouse 4 Warehouse 5 demand 950 650 demand 750 850 DEF has the possibility of storing widgets at its warehouses. The storage costs per widget from one month to the next are Unit cost 15 20 800 1000 Unit cost 20 15 capacities 700 900 capacities 900 1100
