SADfLOR/SAGfLOR

General System description

System name: Simulador de Alternativas de Gestão

Acronym: SAGfLOR

Brief Overview

SAGfLOR is the prescription writer of general system SADfLOR. SAGfLOR connects to the Management Information System INfLOR allowing for complex area selection procedures and generation of prescriptions or Linear or MIP programming models to be solved by the decision support models (DECfLOR).

Support for specific issues

Harvest scheduling, coppices management, cork yield.

Support for specific thematic areas of a problem type

• Silvicultural
• Certification
• Conservation
• Development choices / land use zoning
• Policy/intervention alternatives

Related systems

SAGfLOR is part of the set of tools SADfLOR, whom also belongs:

• INfLOR
• DECfLOR

Data and data models

Selecting management alternatives for the DUNAS model

Typical spatial extent of application

It can be used both in forest and stand level.

Forest data input

Some data is required in order to build the management alternatives.

Type of information input from user (via GUI)

The user has to add some information in order to build the appropriate model, as target products flow or spatial relationships.

Models

Forest simulation models

SAGfLOR was built as an architecture that allowed adding modules for including several types of silviculture and species. In its current form it allows for simulation of the most important Portuguese forest species, namely:

• Maritime pine (Pinus pinaster Ait.)
• Cork oak (Quercus suber L.)
• Eucalypt (Eucalyptus globulus Labill.)

For simulation of Maritime pine stands was used on the northern coastal region, the stand level model DUNAS^[1], and another model for inland mountainous regions ^[2]. For Eucalypt the version 1.0.1 of the GLOBULUS^[3] model was implemented. Cork oak was the sole species that inclued an individual tree model, based on the SUBER ^[4] growth and yield individual tree model.

Types of outputs

SAGfLOR outputs are harvest schedules shown in screen and ready to be used by the DECfLOR optimization tool.

System

System requirements

• Operating Systems: Microsoft^® Windows™ OS

Architecture and major DSS components

It was developed using Microsoft Visual Basic™ and MapObject LT™.

Documentation and support

A user's manual has been published^[5].
