Table A.3: Java code for calling AMPL from the Java file OBA.java
cmdarray[0] = “/bin/bash”;
cmdarray[1] = “-c”;
cmdarray[2] = “./ampl NetworkModel.run”;
try
{
process p = Runtime.getRuntime().exec(cmdarray);
p.waitFor();
System.out.println(“—- AMPL solver has finished —-”);
}
catch (Exception e )
{
System.out.println(“Error process”);
System.exit(1); // for abnormal termination
}
The file NetworkModel.run contains the following AMPL commands:
model NetworkModel.mod;
data NetworkModel.dat;
option solver ‘./snopt’;
solve;
display { k in GreedyConnections } (sum { tinIntervals}
AMPL AllocatedBandwidth [ k,t ]) > AllocatedBandwidth.out;
display AMPL NetworkRevenue > NetworkRevenue.out;
quit;
- NetworkModel.mod is a file that describes the network model
using standard AMPL format.
- NetworkModel.dat is a file that provides the network model
parameters.
- AllocatedBandwidth.out and NetworkRevenue.out are two output
files that contain, respectively, the connections’ allocated rate and
the total network revenue calculated by AMPL.
