ILOG CPLEX 11.0 User's Manual

●The fact that a limited amount of raw oil can be stored for later use is expressed likethis:if (i == 0) {for (IloInt p = 0; p < nbProducts; p++)model.add(500 + buy[i][p] == use[i][p] + store[i][p]);}else {for (IloInt p = 0; p < nbProducts; p++)model.add(store[i-1][p] + buy[i][p] ==use[i][p] + store[i][p]);}What Is the Objective?On a monthly basis, the profit can be represented as the sale price per ton (150) multipliedby the amount produced minus the cost of production and storage, like this, where profitis defined as IloExpr profit(env);:profit += 150 * produce[i] - IloScalProd(cost[i],buy[i]) - 5 * IloSum(store[i]);Developing the ModelFirst, create the model, like this:IloModel model(env);ILOG CPLEX 11.0 — USER’ S MANUAL 363
