Dear researchers,
I am interested to perform researches in logistics field, which has new contributions theoretically, or related with new technologies. I am doing mathematical modeling (and solving them using LINGO, while I am learning to use CPLEX), and I am also interested in developing heuristics/metaheuristics to solve the problem (I have implemented Genetic Algorithms using Java programming language; and I have also used Matlab before).
I am looking for any researchers who may have some ideas and need some help to apply their algorithm in the mathematical model or heuristic, and specially for researchers who may do the mathematical modeling/implementation as well. If we have same interests, then we may also share good research ideas.
I am currently aiming for publications in good journals.
If we can collaborate, please let me know.
Thank you.
Best regards,
Ivan K. Singgih
