Vestnik UGATU , 2013,
Abstract: В настоящей статье рассматриваются цели и задачи системы среднесрочного планирования производственных предприятий. Описывается функциональность основного планирования ERP-систем как инструмента решения задачи среднесрочного планирования. Приводятся ее возможности и недостатки. Рассматривается прототип математической модели, программная реализация которой позволит дополнить функциональность ERP-систем и получать оптимальные планы загрузки оборудования и закупки критических материалов. Вводятся обозначения. Формируется система ограничений, накладываемых на модель, а также приводится целевая функция. Дается алгоритм работы с моделью. Также, на примере самолетостроительного предприятия, производится апробация полученной модели средствами MS Excel.
节能液压源阀控系统自调节前馈补偿技术  [PDF]
北京理工大学学报 , 1999,
Abstract: 目的减少由于节能液压源下的阀控系统变增益带来的跟踪误差。方法提出位置跟踪系统开环增益的观测器设计方法,运用自调节前馈原理对控制系统进行动态补偿。结果实验证明动态补偿方法提高了位置跟踪精度。结论采用自调节前馈补偿技术能够有效地减小由变增益带来的误差。
基于空间脉宽调制控制技术的双馈风力发电机动态性能研究  [PDF]

电网技术 , 2009,
Abstract: 针对异步发电机功率变化波动大、暂态性能差,故障情况下无法持续供电等诸多不利因素,首先提出了双馈风机的简化数学模型,基于空间脉宽调制(spacepulsewidthmodulation,SPWM)控制技术,利用方程直接解出了定子输出功率和转子电流的数学关系;然后设计了PI控制器实现了双馈风力发电机有功功率和无功功率的解耦控制,并通过调节控制器增益,加快了风机转子侧的无功响应速度,极大地改善了双馈风力发电机接入电网的暂态性能;最后将该发电机模型放入9机微型电网系统中进行了稳态和故障2种情况下的仿真。仿真结果表明该控该制策略合理有效,不仅能成功实现有功和无功的解耦控制,且能较大提高电网暂态性,保证了变速恒频风电机组并网后的稳定运行。
MAXIMIZING THE BENEFITS OF ERP SYSTEMS
Paulo André da Concei??o Menezes,Fernando González-Ladrón-de-Guevara
JISTEM - Journal of Information Systems and Technology Management , 2010,
Abstract: The ERP (Enterprise Resource Planning) systems have been consolidated in companies with different sizes and sectors, allowing their real benefits to be definitively evaluated. In this study, several interactions have been studied in different phases, such as the strategic priorities and strategic planning defined as ERP Strategy; business processes review and the ERP selection in the pre-implementation phase, the project management and ERP adaptation in the implementation phase, as well as the ERP revision and integration efforts in the post-implementation phase. Through rigorous use of case study methodology, this research led to developing and to testing a framework for maximizing the benefits of the ERP systems, and seeks to contribute for the generation of ERP initiatives to optimize their performance.
自然物体分类的erp研究  [PDF]
买晓琴,罗跃嘉
心理科学进展 , 2004,
Abstract: ?对事物进行分类的能力是人类的一种基本认知功能。该文主要就近年来自然物体分类的事件相关电位(erp)研究情况进行综述。首先介绍与自然物体分类有关的erp早晚期成分;接着讨论了快速视觉分类的加工机制,认为前馈机制在这种复杂分类任务的视觉加工过程中起重要作用;最后详细介绍了两个分离的视觉加工机制,认为自然物体的视觉分类在不同时程涉及不同机制:即首先是任务无关的早期知觉加工过程,其次是任务相关的、类别无关的加工机制,与被试的决策有关。也讨论了这两个分离的加工过程涉及的神经基础。
Criteria for the selection of ERP software  [PDF]
Adina UTA,Iulian INTORSUREANU,Rodica MIHALCA
Informatica Economica Journal , 2007,
Abstract: The implementation of an ERP software package is an important investment for an organization, which is characterized also by a high degree of risk. Selecting the most appropriate software is a necessary condition for a successful implementation. This paper is describing the major aspects of software selection in general and the relevant criteria in the case of ERP software.

Knowledge Management Based on ERP
Qian Feng,Yuanyuan Huang
International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v4n3p66
Abstract: In an information explosive era, knowledge management has become a hot field in enterprise informatization. In order to adapt to the competitive environment, it is now an urgent task to add knowledge management to ERP system and integrate learning and innovation on the platform of enterprise information system based on ERP. This paper focuses on knowledge management based on ERP and introduces a knowledge management system: KRM.

Abstract: The article presents research findings focused on the critical success factors in ERP implementation projects. Furthermore, it compares two approaches to the implementation of ERP system of two major systems integrators. In conclusion, the article summarizes the basic features of the lean implementation, implementation methodologies and their use for different types of ERP projects.
Box Resolvability  [PDF]

Mathematics , 2015,
Abstract: We say that a topological group $G$ is partially box $\kappa$-resolvable if there exist a dense subset $B$ of $G$ and a subset $A $ of $G$, $|A|=\kappa$ such that the subsets $\{ aB: a\in A\}$ are pairwise disjoint. If $G=AB$ then $G$ is called box $\kappa$-resolvable. We prove two theorems. If a topological group $G$ contains an injective convergent sequence then $G$ is box $\omega$-resolvable. Every infinite totally bounded topological group $G$ is partially box $n$-resolvable for each natural number $n$, and $G$ is box $\kappa$-resolvable for each infinite cardinal $\kappa, \kappa<|G|$.
