Two case studies are described for evaluating tenders in information techno
logy (IT) in public procurement process based on multiattribute group decis
ion models and the software WINGDSS. The:given decision methodology is furt
her developed by discussing a method to aggregate scores measured on a scal
e and price.
In 1997, 17 parallel tenders were handled together, 468 offers were evaluat
ed by eight decision-makers, in two rounds, with respect to 18 and 5-8 crit
eria, respectively, in 5 days. In 1998, the same problem resulted in 168 of
fers, which were evaluated in one round by nine decision-makers with respec
t to 100-150 criteria, in 3 days.
Since 1997, goods worth of 4-5 billion HUF (approximately 200-300 million U
S$) per year have been purchased within the frame of the contracts yielded
by the tenders. (C) 2000 Elsevier Science B.V. All rights reserved.
