- The constraints and objective function in linear form

- Define the meaning of each variable

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