产品结构优化中应注意的几个问题

Problems Deserving Attention in the Optimization of Products Structure

在运用线性规划方法优化企业的产品结构时,应当在目标函数中引入产品价格和各种资源的价格等信息,用单位产品的毛利作为目标函数中决策变量的系数。并应根据使硬约束成为紧约束的原则,不断调整软约束的资源可用量,尽可能使所有的约束条件都达到紧约束的程度,才能保证得到最优方案。

In the optimization of products structure with linear programming method, information as prices of products and various resources should be induced into the objective function and use the gross profit of unit product as the coefficient of decision variable in the object function. The available quantity of soft constraints resources should be adjusted continuously according to the principle of turning hard constraints into tight constraints. As long as all the constraint conditions are to the degree of tight constraint, the optimum scheme can be ensured.
