露天矿生产中车辆安排问题的多目标非线性规划模型

露天矿生产的车辆安排问题在许多类似生产领域中具有一定的代表性，针对露天矿生产中的一个多目标优化运输问题，基于数学分析，建立了一个多目标非线性规划模型；提出了模型的逐步整数化方法和穷举整数化方法两种快速算法，并利用研制的Matlab程序计算了一个实际问题，计算结果证明该模型和程序是有效的，并可以在生产实践中使用。

Multiobjective Non-linear Programming Model of the Transporting Arrangement in the Production of Strip Mine

The scientific arrangement for transporting vehicles in the production of strip mine is a typical problem in many similar fields. On the basis of mathematical analysis, a multiobjective non-linear programming model on a multiobjective transporting vehicle arrangement is set up. Two fast arithmetic methods, i.e. gradual integralization method and enumerative integralization method, are put forward hereafter and an actual problem is solved by making use of the Matlab program. According to the calculating results, the model and its program are valid and therefore can be applied to many practical production fields.
