根据畜牧业的一般统计方法,对畜群结构间的关系,进行定性分析、定量描述、数学模拟,获得的数学模型是一个多变量的带约束条件的线性规划问题。本文着重探讨一个畜群结构最优化的程序设计思想、方法、程序,及如何使用本软件,对不同畜种、不同的结构模型,规划出最优化结构方案。一、计算方法(一)问题的简述线性的规划模型(Lincar PnognammingMade)以下简记为 LPM。它是在满足一组以线性约束和变量为非负值的限制条件下,求
According to the general statistical method of livestock husbandry, the relationship between the herd structure is qualitatively analyzed, quantitatively described and the mathematical simulation is performed. The obtained mathematical model is a multivariable linear programming problem with constraints. This article focuses on the concept, method and procedure of program design for the optimization of herd structure, and how to use this software to plan the optimal structure for different livestock species and different structural models. First, the calculation method (A) a brief description of the problem Linear programming model (Lincar PnognammingMade) hereinafter referred to as LPM. It is to meet a group of constraints and variables are non-negative constraints
