A Business Intelligence Methodology for E-government Reverse Auctions

In the first quarter of year 2008, electronic reverse auctions (e-RAs) allowed the Brazilian Government to save up to US$ 270 million, which account for 87% of its acquisitions in the period, against 1% in the same period 6 years earlier - according to the Ministry of Planning, Budget and Management. A tool of such importance is subjected to fraud or even anomalous behaviors, which are difficult to detect with simple analysis over the current system. In this paper we look forward into identifying suspicious behaviors in e-government procurement systems, through the use of business intelligence techniques. The results confirm that our methodology can help discovering interesting aspects that can be used to help market players indecision support and auctioneerpsilas management.
