D.  aA review of bio-economic simulation models of beef production systems and suggestions for methodological development.h[electronic resource]  c1982  aThis paper sets out to review eight beef production simulation models constructed over the past decade. All eight models are identified as belonging to a class of bioeconomic model referring to beef grazing systems at the level of the farm firm. Aspects given consideration in the review include model objectives, the handling of biological and economic components of beef production systems, risk and management variables and the uses to which the various models have been put. Various aspects of the development and use of such models are discussed, including alternative future courses for methodological development.  aBeef cattle  aSimulation models  astatistical analysis  aEstatística  aGado de Corte  aSistema de Produção  aBovino de corte  aFarming system  aModel  aModelagem e simulação  aModelo  aModelos de simulação1 aCEZAR, I.
