水产的养殖与捕捞的数学模型

The Mathematical Models of Multiplication and Catch of Aquatic Products

对于养殖场中虾的养殖和捕捞问题,建立了各量的基本模型。对三种不同情况,应用微分法和规划论,分别建立了相应的微分规划模型、积分规划模型和变分法模型。再应用微分法、变分方法及Maple数学软件进行求解,对不同情况得出了相应的数值结果。

In this paper, it deals with the problem of multiplication and catch of aquatic products . First of all, it establishes basic models of numbers. In accordance with three different cases, corresponding differential plan models, integral plan models and calculus of variations models are set up with the method of differentiation and plan theory. And then work them out to every case with the application of differentiation and calculus of variations and Maple (a mathematical soft) . It gets corresponding numbers results.
