Interested in how computer technology aids in managing the aftermath of Chernobyl? This paper introduces a computer technology (CT) developed for modeling the ecology-economic situation in the alienation zone (AZ) of Chernobyl, comprising databases of potentially dangerous objects and program modules (PM) to model the ecology-economic situation in the AZ. Critical values of measured parameters are also determined, at which achievement the emergencies can occur. This model determines the optimal redistribution of means directed at resource restoration, liquidation of technogenic pollution, the restoration of basis capital, and prevention of pollution migration for bounds of the AZ. A distinctive feature of accounts allows the estimation not only of risk value, but also of levels of reserve possibilities of various objects. The CT includes PM for risk assessment of emergency occurrences, a geo-information system, and PM for dynamic optimization tasks. These modules optimize the situation and resources related to ecology in the area.
