Research Areas
Areas
My research interests include modeling and analysis of manufacturing and inventory systems by using the optimization tools and computer simulations. The manufacturing and inventory problems of my interest are in the area of dynamic lot sizing, learning and forgetting in production environment, supply chain management, quality control, maintenance scheduling, appplications of Data Envelopment Analysis and management information systems.
