Environmental Impact Assessment: assessment results
Assessment resultsThe primary assessment result is a matrix of average annual concentrations In the domain source, shown as a color coded map overlay. The parallel statistical information includes:
Receptor PointsHourly values are extracted for all Receptor Points. These time series of hourly data for these locations are summarized in terms of:
Buttons in the header of the receptor point list can
ComplianceThe time series extracted for each location can be further analyzed against a user-defined air quality standard, countingthe number of violations and computiung basic statistcis of the time series.
Analysis of exceedancesThe spatial distribution of exceedances, and the statistics of the corresponding matrices are accessible in a separate bapge, triggered by the button in the main scenario header: Maxima.
Complex optimizationFor a given source, the user can specify several emission control strategies (they can be mutually exclusive or freely combined) with their associated emission reduction efficiencies and cost functions (annualized investment, operating costs), as well as technical measure such as different stack height with their associated costs. The model find the minimum cost configuration to meet a set of user defined constraints. From the set of feasible solutions, an optimal solution can be found using a discrete multi-criteria optimization tool.
