Enhancing Web-Spatial DSS interactivity with parallel computing: The case of bio-energy economic assessment in Greece
Kremmydas, Dimitris; Haque, M.I.; Rozakis, Stelios - Department of Agricultural Economics, Agricultural … - 2011
A web based Spatial Decision Support System (web SDSS) has been implemented in Thessaly, the most significant arable cropping region in Greece, in order to evaluate selected energy crop supply. The web SDSS uses an optimization module to support the decision process, incorporating user input...

Decision support for rehabilitation hospital scheduling
Schimmelpfeng, Katja; Helber, Stefan; Kasper, Steffen - Wirtschaftswissenschaftliche Fakultät, Leibniz … - 2010
We present a detailed analysis of the patient and resource scheduling problem in rehabilitation hospitals. In practice, the predominantly therapeutical treatments and activities which are prescribed for the patients are typically scheduled manually. This leads to rigid and inefficient schedules...
