低成本配煤采购系统的研发

低成本配煤采购系统由煤炭特性记录管理系统和煤炭采购优化系统组成。煤炭特性记录管理系统可以对所有炼焦煤的性能参数进行记录、修改、计算,求出不同时间段内煤炭性能参数的平均值,为煤炭采购系统提供煤炭性能数据。煤炭采购优化系统可以在煤炭质量、焦炭质量预测、煤炭净价格(煤炭价格-副产价格)、煤炭采购等限制条件下,利用SOLVER规划求解的方法,自动得出满足焦炭质量要求和所有采购限制条件的净价格最低配煤采购方案,从采购环节实现对焦炭高质、稳产、成本最低的长远控制。

Development of low cost purchasing system for coal blending

The low cost purchasing system for coal blending consists of coal property recording manage- ment system and coal purchasing optimization system. The coal property recording management system can carry out the recording, modification, computation of property parameters of all coals for coke making, ob- tain the average values of coal property parameters within different time periods and provide coal property parameters for coal purchasing system. The coal purchasing optimization system can obtain the minimum price purchasing proposal for coal blending that can meet the coke quality requirement and net price under all restricting conditions automatically by utilizing SOLVER planning and solving method, under the re- stricting conditions such as coal and coke quality predictions, net price of coal （coal price-byproduct price）, coal purchasing etc. so as to realize the long term controls of the high quality, stable production and mininmm production cost of coke from the purchasing link.
