如何在CPLEX流控制中设置capFlour每次调整间隔为100

修改方法 #

你当前代码中capFlour++语句的作用是每次迭代将面粉容量上调1，要改成每次调整间隔为100，仅需替换这一行代码即可：

• 找到代码中的capFlour++;语句
• 将其修改为capFlour += 100;

修改后的完整代码如下：

main {
 thisOplModel.generate();
var produce = thisOplModel;
 var capFlour = produce.Capacity["flour"];
 var best;
 var curr = Infinity;
 var ofile = new IloOplOutputFile("mulprod_main.txt");
 while ( 1 ) {
 best = curr;
 writeln("Solve with capFlour = ",capFlour);
 if ( cplex.solve() ) {
 curr = cplex.getObjValue();
 writeln();
 writeln("OBJECTIVE: ",curr);
 ofile.writeln("Objective with capFlour = ", capFlour, " is ", curr);
 } else {
 writeln("No solution!");
 break;
 }
 if ( best==curr ) break;
 capFlour += 100;
 for(var t in thisOplModel.Periods)
 thisOplModel.ctCapacity["flour"][t].UB = capFlour;
 }
if (best != Infinity) {
 writeln("plan = ",produce.Plan);
 }
 ofile.close();
}

修改后每次迭代都会将面粉容量上限上调100，满足调整间隔的需求。
