NetWeaver

General System description

System name: NetWeaver

Brief overview

NetWeaver is knowledgebase development system that provides a graphical environment in which to construct and evaluate knowledge bases. Knowledge representation in NetWeaver is based on object-oriented fuzzy-logic networks which offer several significant advantages over the more traditional rule-based representation.

tool encourages decision maker to discover new problems or opportunities by exposing to new information or results
tool helps decision makers in recognizing upcoming problems for which solutions have been developed previously
tool allows decision maker to actively create new knowledge when faced with a new problem and to develop novel solutions
tool allows decision maker to capture knowledge, making it available to decision makers who are seeking solutions from previously solved problems

System origin

Who and when was it developed
how was it developed
is it a commercial product
does it have real-life application cases

Support for specific issues

Is the system designed to take into account specific uses? E.g. guidance on ways to characterize biodiversity, economic-biodiversity tradeoff analysis methods, risk assessment methods, landscape analysis methods, timber harvest effects, climate change effects, biological effects (pests, pathogens, invasives), fire,...

Support for specific thematic areas of a problem type

Silvicultural
Certification
Conservation
Restoration
Transportation
Development choices / land use zoning
Policy/intervention alternatives
Sustainability impact assessment (SIA)

Capability to support decision making phases

Data and data models

Typical spatial extent of application

Define the scale of use for the application (user defined, regional, multi-owner forest single ownership forest, Multiple scale interaction)

Forest data input

Describe the basic forest input (forest level, stand level, or individual tree level), and appropriate meta-data, such as data provenance (Areal coverage, Sample of plots, stands, Contiguous forest cover). GIS information is to be considered here, namely include cover tyes and type of information (raster or vectorial, necessity of topological information) If necessary describe surrogate sources of information

If necessary describe other types of required data (economic, social)

Type of information input from user (via GUI)

Describe what is the information that the user directly inputs in the system if any): expert knowledge, opinion, goals and production objectives, preferences, stand/site information....

Models

Forest models

Growth, Yield, Carbon, Wood quality, biodiversity and habitat suitability, environmental and external effects (fire, storms, pests, diseases, climate change, etc)

Social models

historical and cultural values of sites, values due to peace and quiet, esthetic values, values due to recreational activities, ethical values): E. g. Recreation, Health, Game

Decision Support

Definition of management interventions

Define what is available for the manager to intervene in the forest: time of harvest, plantations, thinnings, reconversions... Existence of prescription writer, simple enumeration of all possibilities, scenario simulation , etc.

Typical temporal scale of application

Define the temporal scale of the application: E.g., operational and immediate level, Tactical planning (short term) and strategic level.

Types of decisions supported

Management level
- strategic decisions
- administrative decisions
- operating control decisions
Management function
planning decisions
- organizing decisions
- command decisions
- control decisions
- coordination decisions
decision making situation
- unilateral
- collegial
- Bargaining / participative decision making

Decision-making processes and models

Logic modeling
Operations research modeling

Other

Output

Types of outputs

Types of outputs produced (tables, maps, 3-D visualizations, pre-programmed summaries, etc)

Spatial analysis capabilities

integrated capabilities
facilitates links to GIS (wizards, etc.)
provides standard data import/export formats
allows spatial analysis (e.g. topology overlays (e.g. multi layering of different maps, selection of objects based on selection criteria, aggregation by attributes (e.g. areas of similar characteristics), Linking by logical means, Statistics by area, analysis with digital terrain model)

Abilities to address interdisciplinary, multi-scaled, and political issues

Evaluate interactions between different basic information types (biophysical, economic, social). Produce coordinated results for decision makers operating at different spatial scales facilitate social negotiation and learning
