摘要
对一类带有转换点和约束条件的最小化问题,引入L agrange乘子,通过变换,将目标函数中的二次函数化为线性函数,再应用C ram er法则,求出最优解.最后给出了模型的应用.
This paper will discuss the least value with changeover point and constrained condition, lagrange multipliers are introduced, by transformation, quadratic function in purpose function is turned into linear function, then Cramer rule is used to achieve optimum solution. Finally model application is offered.
