The latter were involved during the entire project and provided real-life requirements and test cases, which motivated the models and optimization algorithms developed by ISA. This prototype was publically presented to the Iberian Forest community during the FOP workshop organized by the partnership.

| − | === Support for specific issues === | + | |Has country=Portugal |
| − | SADDPOF aims to provide optimized FOP scenarios and facilitate subsequent trade-off analysis. Its current scenarios establish monthly harvest schedules for different wood product assortments as well as its distribution networks from harvest sites to transformation centers, including terminals for intermediate storing. The harvest scheduling sub-problem accounts for spatial constraints, monthly forest roads accessibility and contractual obligations forcing harvest to occur before land rental contract expiration. The distribution sub-problem fulfills the monthly qualified destinations demands and relays on other specific transportation-distribution constraints, like road and railway transportation costs minimization, terminals maximum storing capacity and maximum storing time.

The GIS visualization and reporting templates meet the users’ real-life requirements.

| − | SADPOF yearly harvesting stands sub-set results from with other strategic forest planning systems, such as [[SAGfLOR]]. The scenario characterization information can be resident in other related systems, like the forestland patrimony management system. Currently, SADPOF data canalization relays on pre-defined import formats, although integration interfaces can be developed. Similarly, the pre-defined outputs can feed other systems downstream of the planning process, such as forest services adjudication and operations follow-up systems.
