متن کاملApplication of Rough Set Theory in Data Mining for Decision Support Systems (DSSs)
Decision support systems (DSSs) are prevalent information systems for decision making in many competitive business environments. In a DSS, decision making process is intimately related to some factors which determine the quality of information systems and their related products. Traditional approaches to data analysis usually cannot be implemented in sophisticated Companies, where managers ne...
متن کاملDeveloping optimal operating reservoir rule-curves in drought periods
In this study a simulation-optimization model is developed for deriving operation rule-curves in drought periods. To each reservoir, two rule-curves with adjustable monthly levels are introduced dividing the reservoir capacity into three zones between the normal water level and minimum operation level. To each zone of a reservoir and for each month of the year a hedging coefficient is introd...
