摘　　要：为了确定大型养猪场的最优经营策略,以5个生产周期(每周期39周)为时间样本进行分析和优化,建立了母猪、种猪、乳猪、小猪数量的动态演变方程,再以利润最大化建立了优化模型,以肉猪和猪苗的预测价格为主要参数,通过计算机模拟获得了未来195周的最优经营策略。To identify an optimal business strategy for a large-scale pig farm,five production cycles are analyzed and optimized as samples.A dYnamic equation of sows,hogs,piglets and weaners is constructed to formulate the optimization mbdel for maximum profit.Utilizing estimated prices of feeder pig and suckling pig as major indexes,the optimal business strategy of the next 195 weeks has been acquired throughcomputer simulation.
