Past Research

In the past have I worked on several different subjects ranging from production planning and control to nonlinear optimization. I was quite lucky, since I had the chance to work with excellent researchers from different parts of the world. Below is a list of subjects, on which I had worked and published. Though, I do not currently work on some of them, I am open to go back, especially when, someone leads me to an interesting problem. I have no doubt that there are still many exciting problems out there within the scope of these subjects:

• Hierarchical production planning.
• Capacitated lot sizing and loading.
• Global optimization.
• Heuristics and search methods.
• Joint replenishment.
• Generalized fractional programming.
• Linear and nonlinear complementarity.
• Equilibrium constrained optimization.
• Smooth approximation of max function.
• Sample path method and its applications.

I also worked in (or been funded by) the following research projects:

• Decision Support Tools for Supply Chain Management, NC, Raleigh, USA.
• Mathematical Programs with Equilibrium Constraints for Network Economics, Rotterdam, The Netherlands.
• Hong Kong RGC Earmarked Grants, Hong Kong, China.
