| |
| − | === Scope of the system ===
| |
| − | SADPOF allows forest practitioners to simulate alternative FOP scenarios and computer economical and ecological scenario evaluation indicators for further scenario comparison. The results of the selected management scenario can be visualized into a GIS integrated module or presented in several pre-defined reports, like the Operational Plan.
| |
| − |
| |
| − | === System origin ===
| |
| − | The SADPOF prototype has developed in 2007-2008 in the course of Portuguese funding research project, coordinated by the IT Company Link Consulting [http://www.link.pt], with the scientific partnership of Instituto Superior de Agronomia (ISA) [http://www.isa.utl.pt] and the forest business experts from Grupo Portucel Soporcel [http://www.portucelsoporcel.com/pt/]. 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.
| |
| − |
| |
| − | It is still a work in progress as its current version implements a sub-set of the foreseen SADPOF functionalities. Further developments can include its productization and installation into real-life application cases.
| |
| − |
| |
| − | === Support for specific issues ===
| |
| − | 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.
| |
| − |
| |
| − | Furthermore, its novel technical architecture foresees specific decision support features, such as user’s scenario parameterization screens, scenario cloning for creating new scenarios based on existents, scenarios queue for accessing its processing status and automatically triggers simulation and optimization events. The GIS visualization and reporting templates meet the users’ real-life requirements.

| |
| − | * Silvicultural
| |
| − | *Product Assortment
| |
| − | * Assignment and distribution
| |
| − | * Development choices / land use zoning
| |
| − | Further developments will implement transportation planning and crews scheduling.
| |
| − |
| |
| − | === Capability to support decision making phases ===
| |
| − | * ''Intelligence:'' SADPOF provides a structure approach to FOP problems as it identifies required information, allows the selection and parameterization of the management goals and constraints. It contributes for capturing existing technical knowledge and generates new decision support basis information through optimized scenarios economical and ecological assessments and trade-offs analysis.
| |
| − | * ''Design:'' SADPOF simulates and assesses alternative FOP scenarios related within the goals and constraints selected by users.
| |
| − | * ''Choice:'' SADPOF provide optimized solution for each FOP scenario, driving the decision-maker to choose among the best solutions.
| |
| − | * ''Monitor:'' SADPOF is restricted to planning purposes. However its integration with operations follow-up system is foreseen, with special interest for adaptive real-time planning features.
| |
| − |
| |
| − | === Related systems ===
| |
| − | 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.

| |
| − | === General system functioning ===
| |
| − | The user starts by creating a new FOP scenario or consulting the scenarios processing status in the Scenarios queue. The FOP scenario includes selecting one model and solution method, their parameters configuration, all the required business data and afterwards, the optimization results. Thus, the users operations in the SADPOF are:
| |
| − |
| |
| − | *''New FOP scenario creation:'' selection of the model and solution method
| |
| − | *''Scenario parameterization:'' the model and solution methods have default values, with can be changed by the user.
| |
| − | *''Scenario simulation:'' automatic system operation for decision variable generation and business data canalization. The simulated scenario can be optimized within SAPDOF optimization module or exported to CPLEX.
| |
| − | *''Scenario optimization:'' automatic system operation for solution method execution. Ends with the generation on the Operational Plan and the other SADPOF outputs.
| |
| − | *''Scenario cloning:'' corresponds to the exact replication of a selected scenario (model, solution method, business data, parameters) on the created or simulated status. This feature enables rapid new scenario creation for further parameterization, aiming scenarios comparison.
| |
| − | *''Scenario analysis:'' the scenario optimization results can support profitability assessments and trade-off analysis.
| |
| − | *''Scenario queue consultation:'' presents the status of each FOP scenario and their direct link. Several scenarios can be created almost simultaneously. Their processing sequence is automatically managed by the Scenario queue.
| |
| − | *''Operational plan consultation''

| |
| − | === Types of outputs ===
| |
| − | The results of the selected management scenario can be visualized into a GIS integrated module or presented in several pre-defined reports, like the '''Operational Plan'''. This excel report presents monthly harvest schedules and monthly qualified wood flows between the origins and destinations, in order to maximize the forest operations net present value (NPV) and to fulfill the management objectives and constraints. It further expresses the scenario optimization results summary which can be used to perform scenario '''profitability analysis''' (e.g., individual NPV contributions of harvest transportation from stands and transportation from terminals into the final NPV result, limiting and non-limiting constraints, obtained vs. target deviations for the limiting constraints, weights and penalties given to each unitary deviation). Additionally, '''trade off analysis''' can be performed, through generating identical scenarios, changing some model parameters and conducting their optimized results comparison (e.g. impact of terminal capacities increment, existence/value of transformation centers self-supply levels, existence/level of terminals minimum level of supply, increasing the penalty of the maximum area limitation constraint, existence/value of the terminals maximum storing time, wood product prices variation in some destinations, operations costs variations, inaccessibility of the forest roads for some stands during winter).
