Blast furnace scheme design is very important, since it directly affects the performance, cost and configuration of the blast furnace. An evaluation approach to furnace scheme design was brought forward based on artificial neural network. Ten independent parameters which determined a scheme design were proposed. The improved threelayer BP network algorithm was used to build the evaluation model in which the 10 independent parameters were taken as input evaluation indexes and the degree to which the scheme design satisfies the requirements of the blast furnace as output. It was trained by the existing samples of the scheme design and the experts' experience, and then tested by the other samples so as to develop the evaluation model. As an example, it is found that a good scheme design of blast furnace can be chosen by using the evaluation model proposed. 相似文献

The layout design of a satellite module belongs to a three-dimensional (3D) packing problem with mutual-conflicting performance constraints. Taking the layout design of a simplified commercial communication satellite as a background, based on the cooperative coevolutionary framework, this paper presents a coevolutionary method with heuristic rules for the optimal layout design of a satellite module. First, a whole satellite module layout problem is decomposed into several sublayout problems according to the multisubphysical structure of a satellite module. Second, a relaxation model is adopted to distribute all objects among subspaces. Third, a coevolutionary genetic algorithm is adopted to solve the detailed layout design within the subspaces. Finally, a heuristic combination-rotation (CR) method is adopted to adjust the constraints to obtain the final whole layout scheme. Compared with the coevolutionary approach and the all-at-once optimization approaches, computational results show that the CR method can improve the computational accuracy of solutions and the proposed heuristic coevolutionary method can produces better solutions within short running times. 相似文献

放矿计划是自然崩落法矿山生产过程中最重要的环节.针对传统手工编制放矿计划随意性大及出矿品位不均衡,在对其进行科学系统的分析基础上,本文运用混合整数规划法解决自然崩落法放矿计划优化问题.以计划期内与目标品位偏差最小为目标函数,综合考虑矿量、品位、放矿速率、崩落指数、排产指数等约束条件,构建放矿计划优化的混合整数规划模型,并在MATLAB环境下用YALMIP编写模型语言调用CPLEX求解器进行求解,使品位波动降低18%,进而得到最优短期放矿计划方案.经实例验证,此方法科学可行,对充分发挥自然崩落法的优越性和提高矿产资源的回收率具有重要的理论和现实意义. 相似文献
