自动优化露天矿短期进度计划的渐进细化法

分析了露天矿生产计划技术现状,提出计算机辅助设计法与数学规划法有机结合是制定露天生产进度计划的最佳手段.针对整数规划和具有前后时段顺序的0-1整数规划在露天矿生产进度计划应用中存在的问题,提出了渐进细化的生产进度计划优化方法,论述了渐进细化过程,建立了相应的0-1整数规划模型.在VC++环境下通过调用LindoAPI实现模型求解,该细化0-1整数规划方法,较前后时段0-1整数规划方法提高了计算速度,满足设计细化需要.

Progressive Thinning Algorithm for Automatic Optimization of Short-Term Scheduling of Open-Pit Mine

The current status of open-pit mine technology was analyzed,and the best approach for open-pit mine production schedule that combines computer aided design and mathematical programming was proposed.In order to resolve the existing problem of open pit mine production scheduled using integer programming and 0-1 integer programming in order of time period,a progressive thinning algorithm for optimizing the open-pit mine production schedule was proposed.Also,the progress of progressive thinning algorithm was discussed and the corresponding 0-1 integer programming model was established.The model was solved by calling LindoAPI mathematical software under the Visual C+ + programming environment.This 0-1 integer programming method has higher computing speed and meets the requirement for detailed industrial design.
