不定需求情形下确定生产批量的方法

引入模糊技术，在只考虑产品的生产成本、潜损成本、折价成本、存储成本情况下，建立了具有单生产周期、需求不确定情况下的最佳生产批量模型。并以成本最，λ—化为目标，运用模糊数的隶属函数、λ—截集的相关理论，采用模糊数的积分值指标排序法，推导出了模型的最优解。即：成本最小的最佳生产批量。该方法特别适合那些缺乏历史数据和统计数据的情况，具有广泛的实用性。     

Some Properties of Fractals Generated by Linear Cellular Automata

Fractals and cellular automata are both significant areas of research in nonlinear analysis. This paper studies a class of fractals generated by cellular automata. The patterns produced by cellular automata give a special sequence of sets in Euclidean space. The corresponding limit set is shown to be a fractal and the dimension is independent of the choice of the finite initial seed. As opposed to previous works, the fractals here do not depend on the time parameter.     

光滑流形在(Z2)2作用下信息为{(2,2,0),(2,0,2),(0,2,2)}的上协边类

设(Z2)^2作用于光滑闭流形M^n，其不动点集的法丛的信息为P＝{(2，2，0)，(2，0，2)，(0，2，2)}，Jn^4，2(P)是有代表元M^n且具有上述性质的n维上协边类[M^n]构成的集合．作者通过构造上协边环M0n的一组生成元决定了Jn^4，2(P)的群结构．     

Design and Implementation of a Novel Algorithm for Iterative Decoding of Product Codes

A novel product code iterative decoding algorithm and its high speed implementation scheme are proposed in this paper.Based on partial combination of selected columns of check matrix,the reduced-complexity syndrome decoding method is proposed to decode sub-codes of product code and deliver soft output information.So iterative decoding of product codes is possible.The fast sorting algorithm and a look-up method are proposed for high speed implementation of this algo-rithm.Compared to the conventional weighing iterative algorithm,the proposed algorithm has lower complexity while offering better performance,which is demonstrated by simulations and implementation analysis.The implementation scheme and verilog HDL simulation show that it is feasible to achieve high speed decoding with the proposed algorithm.
