It highlights the latest advances in the application of operations research (OR) to technology-driven areas in business, finance, and economics, covering both theoretical and methodological developments, as well as real-world case studies. It also explores the connections between OR and other analytical disciplines, such as soft computing and computer science, which can promote the development of new decision support technologies. . 410 0$aLecture Notes in Operations Research,$x2731-0418 606 $aOperations research 606 $aManagement science 606 $aMathematical optimization 606 $aOperations Research and Decision Theory 606 $aOperations Research, Management Science 606 $aOptimization 615 0$aOperations research. 615 0$aManagement science. 615 0$aMathematical optimization. 615 14$aOperations Research and Decision Theory. 615 24$aOperations Research, Management Science . 615 24$aOptimization. 676 $a658.403 700 $aZopounidis$b Constantin$0732748 701 $aAngeliki$b Liadaki$01373386 701 $aMarianna$b Eskantar$01373387 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910734834203321 996 $aOperational Research Methods in Business, Finance and Economics$93404473 997 $aUNINA
