RISK DECISIONS FOR BEEF PRODUCTION SYSTEMS IN THE COLOMBIAN SAVANNAS
通过模拟模型和随机优势方法，研究了哥伦比亚东部热带稀树草原上通过种植高消化率草-豆科牧草来提高粗放放牧系统产出的生产方案，并比较了不同规划期下的风险与投资可接受性。
A beef simulation model was used to examine a range of production possibilities for increasing the output of extensive ranching systems in the tropical savannas of eastern Colombia through the use of sown grass‐legume pastures of higher inherent digestibility than that of the native species. Generalised stochastic dominance was used to compare some promising alternatives with the unimproved savanna‐based production system and with each other. As the planning horizon of the decision maker was reduced, so variability, measured as the coefficient of variation of output, increased significantly. The impact of risk on the long‐term acceptability of a complete investment was limited.
