The PDAS(Production Distribution Area,Spatial)is an efficient method for optimalanalysis of the existing industrial production spatial distribution.As the main problem formedium- and long-term programming of the industrial production level isproject investmentanalysis,incorporation of project investment into PDAS to evaluate the project investmentcomprehensively over the whole planned period will be an ideal approach.This.however,changes the linear programming problem into a mixed integer programming problem withconstraints which include a step function.To simplify the algorithm,in light of large scalesystem decomposition,a model and an algorithm with coordinative running of schedulingand distribution optimization are proposed.The new version of PDAS,named PDAS-D,will have more practical use in decision support analysis for the medium-and long-termproduction spatial distribution and optimal adjustment of industrial structure by means ofproject investment. 相似文献

针对传统的传递对准模型在大失准角下的强非线性问题以及由残余杆臂误差导致的传递对准精度下降问题, 提出了一种改进的惯性系传递对准算法。首先, 对子惯导姿态矩阵进行链式分解, 得到常值姿态矩阵; 然后, 利用罗德里格斯参数等价替代该常值姿态矩阵, 建立关于罗德里格斯参数和残余杆臂误差的具有弱非线性量测的传递对准模型; 最后, 利用非线性滤波对状态进行估计。基于摇摆运动的仿真实验表明, 在存在大安装误差角以及残余杆臂误差情况下, 算法相比于现有方法, 对准速度更快, 对准精度更高, 在5~10 s内即可完成传递对准。车载试验结果也间接说明算法具有更高的传递对准性能。 相似文献

To study the uncertain optimization problems on implementation schedule, time-cost trade-off and quality in enterprise resource planning (ERP) implementation, combined with program evaluation and review technique (PERT), some optimization models are proposed, which include the implementation schedule model, the timecost trade-off model, the quality model, and the implementation time-cost-quality synthetic optimization model. A PERT-embedded genetic algorithm (GA) based on stochastic simulation technique is introduced to the optimization models solution. Finally, an example is presented to show that the models and algorithm are reasonable and effective, which can offer a reliable quantitative decision method for ERP implementation. 相似文献
