===Free text description=== The FMPP integrates economic theory, objective inventory measurements, accurate growth forecasts and optimization methods. The core of the system is a chain of models depicting the production possibilities of a forest holding. A non-linear objective function and mathematical optimization result in a compromise between maximization of economics benefits (Net Present Value) and a sustainable development (sustained net-revenue profile). ==== System origin ==== * The FMPP development started in the early 1970s. * The FMPP was first developed and tested in the forest research holding Remingstorp, and then by Faculty of Forestry of the Swedish University of Agricultural Sciences. There also has been a fruitful cooperation with the HUGIN-project. * The FMPP has been used for analysis of a large number of forest holdings in Sweden. A total of more than 2.5 million hectares has been analysed between 1983 and 1992. ==== Support for specific issues ==== Economic evaluation of the timber resources, adjusting to some forest sustainable management constraints such as a sustained revenue. ==== Support for specific thematic areas of a problem type ==== * Silvicultural * Conservation ==== Typical spatial extent of application ==== Package was developed for the purpose to allow forest companies to do projections their own forest holdings, but it is not well suited for areas of small-scale forestry. ==== Forest data input ==== The FMPP uses forest inventory data such as site quality, age, diameter, number of stems per ha, and species composition. This data can be provided by: * the Swedish National Forest Survey, * long-term experimental trials for estimating effects of treatments such as thinning and fertilizing, * the sample tree material, collected in connection with the FMPP inventory for estimating tree quality and bark volume, * the HUGIN-survey for estimating regeneration results and plant growth. ==== Models ==== Forest growth prediction models are used. Also, economic evaluation through the NPV is made. ==== Definition of management interventions ==== The FMPP determines where (in which stand), when (at which age) and which silvicutural management treatments (harvestings, thinnings, regeneration...) have to be made. ==== Typical temporal scale of application ==== It can be used for operational and strategic planning, although it fits better to strategic planning requirements, since it has been developed toward this goal. ==== Decision-making processes and models ==== The FMPP uses to get the optimum solution linear programming, through the JLP package. ==== Output ==== The results are stored in the form of yield tables.
