Hi
I have been involved in the shipping industry for some years and I am currently undertaking a DBA thesis. Unfortunately I am neither versed in Linear Programming and new to FlexSim. I am desperately looking for somebody / a tutor who can help / assist.
FlexSim does have an optimizer, but it generally solves problems with evolutionary algorithms, rather than with linear programming. The interface provided in FlexSim does not allow the user to control the algorithm in any way; you can only specify inputs, outputs, objectives, and constraints. The optimizer (we use OptQuest) then solves the problem as it sees fit.
As far as being new to FlexSim, I recommend the tutorials. If you have a specific question, you can post it here.
Thank You very much for your response.
1. If i get you well, the linear programming need some assumptions and may not depict the real situation of the model / system in finding the optimal solution. In this the case, then FlexSim might be more useful. However, can a mathematical formulation still be necessary - may be you get my point since academics need formulation. Please clarify / advise.
2. You also mention inputs, outputs , objectives and constraints - can these be for sake of academic requirements) be displayed as mathematical modelling. If so, how.
3. Last but not least, i need some online tutoring on FlexSim or IBM ILOG/Cplex software, can you assist or give me contact persons who can assist.
Thanks to revert.
Best Regards/Bobby
Hi @mahendra R,
First of all you should understand the way Flexsim works very well. We already used FlexSim and Scilab, Matlab, Lindo, Lingo and CPlex to handle LP optimization & simulation analysis. You should know how to work with DLLs inside FlexSim. I'm very sure that FlexSim can work with others optimization tools since we already did it for projects. Good Luck!
Dear Mr Machado
Good day and many thanks for your comments.
As explained, i am neither versed in LP and Flexsim. Can you assist or give me contact details of an online tutor to address and help me.

Please look my article on linear programming in flexsim
