Original abstract

Decision support system described here makes it possible to carry out multicriterial selection of hundreds of projects simultaneously, with tens of criterion functions with bivalent variables including polynomial ones and quotients of linear functions, and tens of resources limitations. Stewart's idea [J. Oper. Res. Soc. 42 (1) (1991) 17] of the special scalarizing function based on the modified reference point approach, which has been hitherto applied for linear benefits and for balance criteria functions only, and its optimization by effective gradient method is used here in the situation described by Santhanam and Kyparisis [Comput. Oper. Res. 22 (8) (1995) 807], involving synergistic effects of second- and third-orders in benefit and cost criterion function, and in resource requirements respecting resource sharing and hierarchical contingency relationships among candidate projects. In addition, the system enables us making the dialogue of the solution in a way of adaptive creation of weights of criterion functions and also flexible projects portfolio changes. A test of efficiency is presented.

Czech abstract

Popsaný systém na podporu rozhodování umožňuje provést simultánní multikriteriální výběr stovek projektů při desítkách kriteriálních funkcí s bivalentními proměnnými, včetně polynomiálních a lineárních lomených funkcí a při desítkách kriteriálních funkcí. Metoda respektuje synergické efekty druhého a třetího řádu v ziskové a nákládové kriteriální funkci a v požadavcích na zdroje a respektuje vzájemnou hierarchickou závislost mezi jednotlivými projekty. Kromě přesné optimalizace systém umožňuje též dialogové zlepšování řešení cestou adaptivní tvorby vah kriteriálních funkcí a flexibilní změny portfolia projektů. Je proveden test efektivity metody.
