EIAxpert is an interactive, rule-based
expert system
for environmental impact assessment.
It is designed for a screening level assessment of
development projects at a an early stage in the project cycle.
The system can operate with a minimum of data and information about the
project, its alternatives, and the environmental setting by drawing on a
generic knowledge and rule base as well as a regional geographical
information system and a set of data bases.
EIAxpert is a generic, completely data driven assessment tool
that can easily be configured for a broad range of application domains
and regions. Applications, projects or studies are represented by a fully data driven structure
of objects. The basic object (an application or study) is defined by a set of Problem Classes applicable
to the combination of a Development project and its location.
The system uses project type (or application domain) with an associated checklists of potential problems,
that are evaluated by RULES in a dialog with the user.
The expert system processes near natural language first order production rules
with a hybrid symbolic and numerical object representation,
optionally georeferenced objects and an embedded GIS,
as well as linkages to data bases and simulation models.
The capability to process both symbolic and numerical data fully
interchangeably makes it well suited for high-level policy analysis.
Its backward chaining inference engine can be embedded in a
real-time forward chaining framework that can provide project management capabilities
and real-time work flow and communication control.

In the current release, the system is fully embedded in the
WaterWare river basin management information system or the EMIS
Environmental Management Informatio System for industrial enterprises and parks or free economic zones.
EIAxpert is a fully web-based client-server system that can utilize all server side analytical tools,
data bases, GIS and models, accessible from any web browser client in
local or wide area networks, Intranet or Internet.
The backward chaining deduction can be linked to any target parameter
to facilitate editing in any of the ESS object-oriented data bases
or model interfaces.
