General System description

System name: GAYA-JLP

Brief overview

Swedish DSS composed of the GAYA stand simulator and the J mathematical programming tool.

System origin

  • GAYA used simulations to describe silvicultural regimes in single sample plots, stands or strata, and employed linear programming (LP) to settle management strategies on a forest level. Further development has taken place since 1990 and the model, today called GAYA-JLP, is now a comprehensive tool for long-term analyses[1].
