== '''Brief Overview'''==
+
 
+
WIS.2 is a decision support system for monitoring and ensuring the sustainable, goal-oriented and efficient management of forest ecosystems, especially with regard to the:
+
* integral handling of significant spatial- and temporal scales in forest ecosystems (i.e., multiscalarity, sustainability);
+
* valorisation of intrinsic multiple ways of using the forest (i.e., multifunctionality, adaptability);
+
* implementation of a liberal and pragmatic view of silviculture as applied in Switzerland (i.e., flexibility, close-to-nature).
+
WIS.2, based on MS Access and ArcGIS View, is composed of different applications, each handling a main aspect of the management of forest ecosystems. As a prototype, WIS.2 is currently being tested in three forest enterprises and promoted by a forest engineering firm. The tool is used at all levels of education for forest management in Switzerland.
+
 
+
WIS.2 was developed during 2001-2005 within the framework of a PhD thesis at the ETH in Zurich (Rosset, 2005 <ref>Rosset, C. (2005): Systeme de gestion sylvicole integree et d’aide a la decision. Les WIS.2, un instrument informatique pour un sylvicole efficient et ceblee, durable, multifontionelle et proche de la nature. Diss. Nr. 16005, EPF Zurich, Zurich</ref>), and has since then been successively developed in an iterative manner using inputs gained from practical experience. Plans are currently being made to refine the tool in a research and development project and launch a commercial product called SMART-Forest.

== '''System Origin''' ==
+
|Has goods and services dimension=Market wood products, Non-market services
As multi-purpose, near-to-nature silviculture seeks to steer forest dynamics towards socio-economic and conservation goals through minimal anthropogenic intervention, the necessity for a powerful forest management decision support system that implements and monitors such silvicultural practices is getting stronger.
+
|Has decision making dimension=Single decision maker
In order to face this challenge, WIS.1 was initially designed in the 1990s by Good and Pistor (1992<ref>Good, E., Pistor, T. (1992): Waldbauliches Informationssystem WIS, Handbuch. Professur für Waldbau, ETH Zürich, Zürich</ref>) as an information system for silvicultural planning at stand level. Under the name of WIS.2 the system evolved from an information system to a DSS by integrating knowledge and supporting the entire decision process of the management of forest ecosystems. Further adaptations have been subsequently made (i.e., prototyping), such as e.g. during a 10-day course on silvicultural planning held at the ETHZ in a small forest enterprise (150ha) owned by the Canton of Zurich.

+
'''Commercial product'''
+
 
+
WIS.2 is not yet a commercial product. However, the system is going to be refined within the framework of a research project and launched as a commercial product through collaborative partnerships under the name of SMART-Forest.
+
 
+
=='''Support for specific issues'''==
+
 
+
'''Silviculture in Switzerland'''
+
 
+
WIS.2 takes a multi-level, top-down, situation-oriented approach and provides foresters with room for maneuvering when specifically determining the most appropriate silvicultural techniques to use in the field. The recommended forest strategy is subsequently implemented within the framework of sustainable forest development. The liberal and pragmatic view of silviculture in Switzerland implies that the suggested planning strategy should leave as much room as possible for maneuvering when implementing the planned intervention.
+
 
+
'''Formalisation of the manifold demands of society and forest owners in silvicultural profiles'''
+
 
+
In order to meet the demands of society and forest owners, the objectives with regard to the desired status of the stands (what to reach), the given conditions of the location (where to intervene) and the related spatial organization (how to coordinate the procedure) need to be clearly specified. In WIS.2, this specification is described in the form of silvicultural profiles that define the desired status of the stands under the given local conditions. Silvicultural profiles are comprised of criteria (e.g., types of trees) and indicators that further specify the criteria (e.g., oak, fir, maple). The grading of the criteria is given at three levels: very important/ very appropriate, important/ appropriate, less important/ less appropriate.
+
 
+
=='''Capabilities to support the decision-making process'''==
+
 
+
WIS.2 supports silvicultural decision-making phases by:
+
* providing valuable information for the different phases of the process and allowing planners to simulate mid- to long-term consequences in varying action scenarios; 
+
* defining different variations of silvicultural strategy and implementation concepts;
+
* assessing the feasibility of action scenarios and revealing the long- and mid-term consequences; 
+
* pointing out the priority of action by connecting long-term strategic planning with mid-term harvesting planning; 
+
* giving guidance on how to react in a flexible way to changes such as market fluctuations and unforeseen events. 
+
 
+
 
+
='''Data and Data Models'''=
+
 
+
=='''Typical spatial extent of application'''==
+
The typical scale of use for the application is the forest enterprise that is comprised of forest stands. The average size of stands range from one to several hectares, and the size of enterprises range between a few hundred to several thousand hectares.
+
 
+
=='''Forest data input'''==
+
 
+
The following forest data are required as input to the system:
+
* Stand description (i.e., regular or irregular stand structure, development stage, tree species composition, cover density, hdom, Ddom;
+
* Phytosociological composition of the stands;
+
* Description of the relief such as exposition and slope;
+
* Information on the road network (i.e., accessibility);
+
 
+
 
+
='''Models'''=
+
 
+
=='''Forest Models'''==
+
Forest models that are taken into account with WIS.2 are: 
+
* Intervention concepts for e.g. tending and thinning (i.e., when to intervene during the stand life, dominant dhb, how to reach the production targets efficiently);
+
* Demographic models for e.g. comparison of current age structure and demographic equilibrium; 
+
* Growth functions for e.g. planned intervention for the next 10 years (i.e., overview of what, where and when);
+
* Expert recommendations on the scope of action for e.g. proportion of softwood or other phytosociological units.
+
 
+
 
+
='''Decision Support'''=
+
=='''Definition of management interventions'''==
+
WIS.2 takes a multi-level, top-down, situation-oriented approach that provides the forester with enough room for manoeuvring when determining which silvicultural techniques to use. WIS.2 enables structuring the process of decision-making by indicating the necessary information for the different stages of the process, allowing planners to simulate the mid- and long-term consequences of different actions. Managers are provided with valuable information on the consequences of different action scenarios.
+
 
+
=='''Typical temporal scale of application'''==
+
The approach to perform planning with WIS.2 spans from a vision in the very long term for a whole forest area (entrepreneurial strategy) to interventions undertaken in the short term at stand level. Silvicultural measures taken with WIS.2 at stand level are typically defined for a planning period of 10 years.  
+
 
+
=='''Types of decisions supported'''==
+
As a silvicultural concept, WIS.2 offers a coherent solution at a strategic and tactical level to reach previously-defined targets. Because trees are long-living and slow-growing organisms, it is necessary to take long-term decisions at the strategic level for the whole forest area (or a part of it) and to define general guidelines. The imbrication of stands in a large and heterogeneous mosaic, for example, means that priorities must be defined and measures co-ordinated at the tactical level between 10 to 30 years).
+
 
+
=='''Decision making process and models'''==
+
The decision making process is an iterative process. First, the user analyses the necessary input to make a decision. This input consists of information and explanatory models. After making the decision, the user analyses its feasibility by comparing it to the present situation and to the targets defined in the previous decision steps. The impact of the decision is simulated using a decision model. The next interface consists of the outputs of the simulation. The decisions taken are recorded at the end, along with comments. In addition to the principle that it must be the user who takes the decision, the following interaction principles have been formulated:
+
* Information is useful to the user if he has easy access to the meta-information (precision, actuality, method of collecting the data);
+
* Decision variables must be introduced to the system by the users (no standard variables);
+
* Interpretation of the simulation outputs is left up to the user,
+
* Models are a simplification of reality. They are only useful if the user knows about the hypothesis and the validation area of the model;
+
* Decision models have many variables so that the user can understand the simulation outputs.
+

=='''Abilities to address interdisciplinary, multi-scaled, and political issues'''==
+
WIS.2 clearly has the ability to address interdisciplinary, multi-scaled- and political issues. The tool utilises semi-quantitative data describing the stands, as well as expert knowledge linked to the (phytosociological units in the) stands. WIS.2 combines wood production with other socio-economic and conservation goals, using a minimum of anthropogenic interventions and taking into account the heterogeneity of site conditions and stand structural types.

+
='''System'''=
+
 
+
=='''Architecture and major DSS requirements'''==
+
 
+
'''Software architecture'''
+
WIS.2 was developed and adapted on the basis of Microsoft® Access 2000/2007 and ESRI ArcGIS® 8.2/9.3. These two applications were selected because of their widespread usage, their full integration into the Windows system (i.e., COM-technology), the possibility of extending their capabilities by using Visual Basic, (a simple programming language), and the ease with which they can create user interfaces.
+
 
+
'''Modularity'''
+
The system is built modularly with geographic, general and specific thematic data modules, along with interface modules such as the data analysis module or the regeneration concept module. Specific data corresponds to a particular forest enterprise.
+
 
+
=='''Usage'''==
+
WIS.2 can be used at research-, industry-, as well as at Government levels.
+
 
+
=='''User Interface'''==
+
[[Image:wis2_gui.jpg|thumb|300px|WIS.2 GUI]]
+
WIS.2 comprises an intuitive user interface that does not require any prerequisite knowledge of the system. The user interface is organised in iterative decision steps. First, the user analyses the necessary input to make a decision; this input consists of information and explanatory models. After making the decision, the user analyses its feasibility by comparing it to the present situation and to the targets defined in the previous decision steps. The impact of the decision is simulated using a decision model. The next interface consists of the outputs of the simulation. The decisions taken are recorded at the end, along with comments.
