Application projects:


Interactive optimisation. Developed a routine library that enables effective implementation of special linear programming procedures. Used in
Property/casualty insurance information system for the Hungarian insurer Atlasz, now QBE Hungary. Took part in designing, and directed implementation and extension works. The system was continually extended in response to new demand: new business lines, changes in ownership and reinsurance structure, introduction of new accounting regulations. The system operated for 12 years. In course of this period the company became an important actor in the Hungarian property/casualty insurance business. Meantime the company was acquired by the QBE Insurance Group (one of the top 25 insurers world wide). The system operated for 6 years after acquisition.


Revision of a risk evaluation system of the Central Clearing House and Depository (Budapest) Ltd, Hungary.
