针对国家烟草管理的现状,有关主管部门在全国推行“行业卷烟生产经营决策管理系统工程”,利用条码等自动识别技术手段实时掌握全国的生产经营信息。但某卷烟厂此前的物流环节已经是“件烟成垛”运输,如何在尽可能保持原有企业管理体系的前提下,达到有关部门的数据统计要求,解决成垛卷烟的物流和信息流的交互与统一问题成为技改的核心。该项目成功的将条码识别与射频识别有机结合起来,为烟草行业信息化提供了生动的应用案例。 相似文献

The paper presents a general approach to the evaluation of the complexity of classes of algorithms, so-called pVCD-method. To develop this method, all the examined families of models of empiric generalization were restricted to classes
implementable on computers and, wider, by examining their partially recursive representations. Within the framework of the
algorithmic approach, the concept of Kolmogorov’ complexity of algorithms for the recognition of properties or the extraction
of regularities is proposed. The method proposed to evaluate the nonrandomness of the extraction of empirical regularities
is based on this concept. 相似文献

In this paper, we study the semicycles of oscillatory solutions of the delay difference equation yn+1 − yn + pnyn-k = 0, where pn is a sequence of nonnegative real numbers and k is a positive integer. Upper bound of numbers of terms of semicycles are determined in the case when Our results improve and complement known results in literature. 相似文献

Computer-aided analysis of autoradiographic films of DNA fragments is presented. The Powell least-squares procedure is used for optimization of parameters for components of complex densitometric curves. Since each densitometric spectrum may be divided for several non-overlapped blocks of bands, there is no upper limit on the number of parameters which must be optimized. Eight shapes for the component bands are utilized: symmetric and asymmetric Gauss and Cauchy functions, direct, symmetric and asymmetric product of Gauss function and inverse of Cauchy function, and log-normal function. The probability of DNA cleavage is calculated with correction for multiple cuts. The methods presented was applied to detailed analysis of densitometric spectra of a 21-bp DNA restriction fragment and allowed for direct correlation between structural microheterogeneity of DNA and the resulting cutting pattern. This method should facilitate the analysis of densitometric data from antibiotic-induced cleavage of DNA and footprinting experiments. 相似文献
