The paper presents a prototype of the integrated decision
support system DECWASTE developed to support decision making in
waste management in the Czech Republic. It uses linked open
data of eGovernment systems of the Czech Republic. It consists
of six sub-modules: PARSER, which downloads the appropriate
data from the eGovernment systems to its databases; PREVENT,
which calculates the prevention impact on waste generation;
FORECAST, which forecasts waste generation for a given time
period using developed mathematical forecast models based on
the DPSIR (Driving forces-Pressures-States-Impacts-Responses)
framework including past time series of waste stream
generation; TREATMENT, which forecasts waste treatment for the
given time period using FORECAST waste generation outputs and
respects the legislation requests; INVEST, which calculates
required investment in the treatment facilities forecast by
TREATMENT and the OUTPUT sub-module, which visualizes and
presents different scenarios for decisionmakers depending on
input data of the PREVENT, FORECAST and TREATMENT sub-modules.
The paper briefly describes information and communication
technologies used in applied eGovernment systems and the
integration of sub-modules PARSER, PREVENT, FORECAST,
TREATMENT, INVEST and OUTPUT into the complex decision support
information system DECWASTE in details.
