Hi,
I have a 4x3 job shop scheduling problem that I need to find it's optimal
solution using matlab codes. I have the codes ready but need to modify
them a little bit.
first code is swarm, already designed for a 6x6 I could change it to 4x3
but the output is given as a gant chart of 6x4 [ 6 machines] so we need
to fix that.
second code is genetic, it's problem is that it gives me the same values
with all iterations even if 50 or 1000 iteration, and I want it to give me
the optimal schedule based on CTime not Tardiness, still I need it to
calculate tardiness.

the times and assigned jobs are as below:
T=[2 3 4
4 4 1
2 2 3
3 3 1];
js=[1 2 3
3 2 1
2 3 1
1 3 2];
Appreciate your assistance in this matter.
Thanks,
