EMIS: Environmental Management Information System
EMIS includes data bases of environmental technologies, including:
The technologies data include substance specific (removal)
efficiencies and associated economic data (unit (annualized) investment costs
and annual operating costs) that can be used in optional
multi-criteria optimization tools to design cost-efficient emission control
and/or waste management systems that meet regulatory standards.
- Emission control technologies for atmospheric emissions;
- Waste treatment technologies linked to the RCRA (hazardous) waste-stream data base.
- Water technologies for efficient use of water resources including recycling and re-use.
In the emission control optimization, one or more alternative control
technologies can be assigned to any one of the emission sources.
The optimization software finds the most cost-efficient combination ans scaling of technologies to
The optimization is based on a two-tier approach, where a first level
generates large sets of feasible alternatives using adaptive heuristics
and genetic algorithms, followed by a (participatory)
discrete multi-criteria approach based on the reference point method
to identify an efficient (compromise) solution from the set of non-dominated feasible alternatives.
- meet given environmental performance standard for a minimum budget;
- maximize environmental improvements for a given budget.
