required: 1) graph the model 2) write the objective function 3) write supply constraints 4) write demand constraints 5) QM solution

Example: Dairy factories in three Palestinian cities produce dairy. These factories supply dairy to three cities, the following tables explains supply, demand of dairy and shipping costs Location Weekly Location Weekly Production Demand (tons) (tons) Bethlehem 100 Ramallah 150 Hebron 200 Jerusalem 50 Nablus 150 Jericho 150 Total 450 Total 350 Bethlehem Ramallah $3 $4 $5 Jerusalem $5 $2 $6 Jericho $3 $2 $1 Hebron Nablus Because of the occupation's closure, shipments are prohibited from Hebron to Ramallah. Formulate this problem as a linear programming model and solve it by using the computer
