General System description
System name: Mesta
Brief overview
An internet-based decision-support application for (participatory) maker strategic-level natural resources discrete choice situations.
Scope of the system
Mesta has been designed to support multi-criteria decision making situations. It works in the Internet. It demands the decision maker to define his/her acceptance threshold (=border of approval) for all predefined criteria. The acceptance border definitions are continued until only one alternative exists that is above the acceptance borders. On the other hand, the functioning reminds approval voting. On the other hand, the functioning reminds feasible region reduction method. However, in Mesta, the alternatives and their criteria values have been created before the approval border definitions.
System origin
Mesta has been developed in Finnish Forest Research Institute.
User rights can be applied from Mikko Kurttila (@metla.fi)
It has real-life applications in four natural resources planning processes of Metsähallitus. The size of the planning areas have been several hundred thousand hectares and typically there has been some 15 participants. They have first used Mesta independently. After this phase and related learning process, group negotiation with Mesta has been carried out, where the final accepted solution for the area has been searched.
Support for specific issues
The Mesta DSS is a general system and it can be applied to numerous decision situations (buying a car, selecting a treatment schedule for stand, and selecting a strategy for a region etc.).
Support for specific thematic areas of a problem type
Strategic planning processes and general discrete choice situations with multiple criteria.
Capability to support decision making phases
Supports the selection phase. Criteria selection, definition of alternatives and estimating the impacts of alternatives has to be carried out before using Mesta.
Data and data models
Typical spatial extent of application
Varies a lot, from stand level to region or country level.
Forest data input
So called result matrix that includes:
- selected evaluation criteria
- predefined alternatives
- estimated outcome from alternative for each criteria
Numerical criteria needs to be used. The aim can be either to maximize or to minimize the criteria value.
Type of information input from user (via GUI)
Two types of users exist:
- A facilitator that defines the decision problem and gives the information of the result matrix. In addition, a facilitator defines the participants.
- A participant gives his/her acceptance border values for each criteria.
Decision Support
Types of decisions supported
- Management level
- applicable to all levels
- Management function
- discrete choice situations (select one of the alternatives)
- Decision making situation
- Unilateral
- Participatory decision making
Decision-making processes and models
- Multiple criteria decision support
- Based on acceptance border definitions from the users and group negotiation
Output
Types of outputs
- Points out the selected alternative
System
System requirements
- Operating Systems: Web-based
- Development status: System in use
Architecture and major DSS components
Web-based system. Utilizes flash-application.
Usage
Used in practical decision making, in projects as well as in research.
Computational limitations
At maximum 10 criteria and 30 alternatives.
User interface
Easily understandable interface, small amount of information demanded from the participant.
Installation
- Directly usable after the user has username and password
- Cost: Case-specific, to be negotiated
- Demo: see www.mesta.metla.fi where a small decision problem is available
