Angelo Sifaleras is an Assistant Professor of Mathematical Programming - Network Optimization at the University of Macedonia, Department of Applied Informatics, School of Information Sciences, Greece, Thessaloniki. His research focuses on algorithms and models for network optimization problems. Currently, he serves as a member of the Editorial Board of the Yugoslav Journal of Operations Research (YUJOR) and he is also a senior member of ACM. Konstantinos Petridis received his Ph.D in Operational Research at Democritus University. His research interests and expertise lie in quantitative methods: mathematical programming models for optimization and design of supply chain networks, mathematical programming models for forest and agricultural scheduling and production and data envelopment analysis models for various scientific fields (bioenergy, computer science, scientometrics, energy). Furthermore, he is working on the field of e-waste management applying advanced forecasting techniques.
