摘　　要：我们为生猪养殖场的经营管理建立了数学规划模型,给出优化经营策略,以提高养殖场的盈利水平。首先,我们利用收益函数得出养猪场的盈利函数,利用盈亏平衡点原理求出达到平衡年产仔量。其次,我们采用人工授精的方式,考虑乳猪、小猪和肉猪的存活率,给出它们的数量,进而得出小猪被选为种猪的比例。再次,我们把928头母猪分成16个组,建立它们收益的优化模型。在不考虑政府补贴的情况下,利用MATLAB计算出的年均利润为220万元。当生猪价格低于养殖成本时,我们会考虑在9个月前不预留种猪,这样母猪最少只有879头,而肉猪最少只有7215头。The mathematical model and the optimal management strategy were set up for pig farms for the purpose of its better profitability. Firstly, we established the profit function of pig farms by using income function, and then we got yearly average bearing amount of 14 to 16 by use of the break-even point principle. Secondly, in consideration of livability of suckling pigs, piglets and hogs, with the method of artificial insemination, we could estimate their respective amount and further that the rate of piglets chosen as breeding pigs was 1.45%, and livestock of sows was 928. Thirdly, we divided 928 sows into 16 groups and set up an income optimization model for each group. Without regard to the government subsides,the average annual profit calculated through MATLAB is $2.2 million. When the price of live pigs is lower than the breeding cost, we will dispose pig breeds nine month before so that only 879 sows and 7215 hogs will be on hand at least.
