Challenges of inter-organizational information and middleware system projects: Agility, complexity, success, and failure 组织间信息和中间件系统项目的挑战:敏捷性、复杂性、成功和失败
Radhouane B. N. Jrad, D. Sundaram
There are two main ways to manage projects in business: The traditional and the agile. While the first has been historically the main Project Management methodology for businesses, the latter is gaining more support for projects involving Information Systems (IS) due to its fitting with the unpredictable nature of IS changes. To assess outcomes of projects, businesses have been using rational, narrative, organizational, and/or performative approaches. While each approach has its strengths and weaknesses, the jury is still out on which is more suitable for IS projects. More specifically, there is a lack of targeted research on which type of project management and which approach for project outcome evaluation are most relevant for Inter-Organizational Information Systems (IOIS) and Inter-Organizational Middleware System (IOMS). IOISs are automated ISs spanning across partnering organizations and aiming at synergizing their forces to increase competitiveness and cost efficiency. An Inter-Organizational Middleware System (IOMS) is the component inside IOIS that is responsible for bridging various partners' systems while holding part of the business intelligence. First, this paper collects and reviews existing project management methodologies; it then evaluates present approaches for assessing outcomes of IS projects, before it focuses on IOIS and IOMS projects, highlighting their unique characteristics and challenges. The paper concludes with a highlight of the research gap into IOIS and IOMS project management.
在商业中有两种主要的项目管理方法:传统的和敏捷的。虽然第一种方法在历史上一直是企业的主要项目管理方法,但由于信息系统(is)变化的不可预测性,后者在涉及信息系统(is)的项目中获得了更多支持。为了评估项目的结果,企业一直在使用理性的、叙述的、组织的和/或执行的方法。虽然每种方法都有其优点和缺点,但哪种方法更适合信息系统项目仍然没有定论。更具体地说,缺乏关于哪种类型的项目管理和哪种项目结果评估方法与组织间信息系统(IOIS)和组织间中间件系统(IOMS)最相关的针对性研究。IOISs是跨合作组织的自动化ISs,旨在协同其力量以提高竞争力和成本效率。组织间中间件系统(IOMS)是IOIS中的组件,它负责在保持部分业务智能的同时桥接各种合作伙伴的系统。首先,本文收集和回顾了现有的项目管理方法;然后评估目前评估信息系统项目成果的方法,然后重点介绍信息系统和信息系统项目,突出其独特的特点和挑战。文章最后强调了IOIS和IOMS项目管理的研究差距。

A downlink scheduler supporting real time services in LTE cellular networks 在LTE蜂窝网络中支持实时服务的下行链路调度程序
Emmanouil Skondras, A. Michalas, Aggeliki Sgora, D. Vergados
The wide spread of real-time services in wireless networks demands scheduling mechanisms supporting strict Quality of Service (QoS) requirements. Nevertheless, the specifications of the LTE standard for mobile connectivity defined by the 3rd Generation Partnership Project (3GPP) does not impose any specific scheduler for the proper allocation of resources to services. Therefore, several LTE schedulers have been proposed in the literature meeting the QoS requirements of modern services. In this paper a QoS aware scheduler for the LTE downlink is proposed namely the FLS-Advanced (FLSA) aiming at prioritizing real-time traffic. The proposed scheduler has been built on three distinct levels assigning the available radio resources to services according to their requirements. Based on simulation results, the FLSA outperforms in terms of packet loss ratio, attainable throughput and fairness the performance of existing schedulers including PF, MLWDF, EXP/PF, FLS, EXP RULE and LOG RULE.
无线网络中实时业务的广泛应用要求调度机制支持严格的服务质量(QoS)要求。然而,由第三代合作伙伴计划(3GPP)定义的用于移动连接的LTE标准规范并没有强加任何特定的调度器来正确分配资源给服务。因此,文献中提出了几种满足现代业务QoS要求的LTE调度器。本文提出了一种面向LTE下行链路的QoS感知调度器FLS-Advanced (FLSA),旨在对实时流量进行优先级排序。建议的调度器建立在三个不同的层次上,根据服务的需求将可用的无线电资源分配给服务。仿真结果表明,FLSA在丢包率、可实现吞吐量和公平性方面优于现有的调度程序,包括PF、MLWDF、EXP/PF、FLS、EXP RULE和LOG RULE。

A FCM analysis for supply chain management 供应链管理中的FCM分析
G. Vlahakis, Dimitris Apostolou
Supply chain consists of many participants across multiple levels of business world. From producers to suppliers, to transporters and to retailers the number of interacting participants rises as the supply chain expands its boundaries. As the size of supply chain grows the problems within it increased too. The modern supply chain is not limited in a small national market where the participants are limited and each one knows its contributor. Modern markets spread their boundaries across continents, where new opportunities and new threats appear. Business relations, political and economic environment determine more or less the performance of the supply chain form a wider sense. In this environment with many concepts causally interrelated, we used the knowledge of the experts and we suggest a FCM that models the key concepts of SC performance showing the exogenous and internal concepts that believed that affect the SC performance.
供应链由跨商业世界多个层次的许多参与者组成。从生产商到供应商,再到运输商和零售商,随着供应链边界的扩大,互动参与者的数量也在增加。随着供应链规模的扩大,其内部的问题也随之增加。现代供应链不局限于一个小的国家市场,参与者是有限的,每个人都知道自己的贡献者。现代市场的边界跨越各大洲,新机遇和新威胁不断出现。商业关系、政治和经济环境或多或少地决定了更广泛意义上的供应链绩效。在这种有许多概念因果关联的环境中,我们使用专家的知识,我们建议一个FCM,该FCM模拟了供应链绩效的关键概念,显示了认为影响供应链绩效的外部和内部概念。

Lung cancer classification tool using microarray data and support vector machines 肺癌分类工具使用微阵列数据和支持向量机
J. Cabrera, Abigaile Dionisio, Geoffrey A. Solano
Lung cancer is one of the deadliest types of cancer around the world. Epidemiologic studies have shown that genetic variability is among the factors that affect a person's susceptibility to lung cancer. A recent study conducted by a team of researchers from the United States National Cancer Institute among 14,000 Asian women found out that Asian women, whether smokers or not, are more prone to developing cancer due to their genetic variations. This study proposes a system that utilizes gene expression data from oligonucleotide microarrays to predict the presence or absence of lung cancer, predict the specific type of lung cancer should it be present, and determine marker genes that are attributable to the specific kind of the disease. The proposed system would help in the faster diagnosis and serve as a reliable adjunct approach to current lung cancer classification methods.
肺癌是世界上最致命的癌症之一。流行病学研究表明,遗传变异是影响一个人对肺癌易感性的因素之一。最近,美国国立癌症研究所的研究小组以1.4万名亚洲女性为对象进行的一项研究发现,无论吸烟与否,亚洲女性由于基因变异更容易患癌症。本研究提出了一个系统,利用来自寡核苷酸微阵列的基因表达数据来预测肺癌的存在或不存在,预测肺癌的特定类型,并确定可归因于特定类型疾病的标记基因。所提出的系统将有助于更快的诊断,并作为现有肺癌分类方法的可靠辅助方法。

Conceptual design of biosensors 生物传感器的概念设计
I. Petrova, V. Zaripova, Yuliya Lezhnina, I. Mitchenko, V. Sokolskiy
Design of biosensors refers to the field of interdisciplinary research, therefore, it is necessary to develop a unified systems approach that is invariant to the physical nature of the used phenomena and processes to create an automated system for conceptual design of such elements. It is appropriate to choose the fundamentals of non-equilibrium thermodynamics as the basis for the development of this approach. They allow to obtain a complete system of transfer equations of the phenomena of different physical nature and other laws, without opening their molecular mechanism. This article discusses the energy-information model of diffusion phenomena, as the processes of diffusion is the general type of the processes that is occurring in bioselective elements. A number of physical effects are described by this model. They are used in the conceptual design of electrochemical biosensors.
生物传感器的设计涉及跨学科研究领域,因此,有必要开发一种统一的系统方法,该方法对所使用的现象和过程的物理性质不变,从而为这些元素的概念设计创建一个自动化系统。选择非平衡态热力学的基本原理作为发展这种方法的基础是合适的。它们可以在不打开其分子机制的情况下,获得不同物理性质和其他规律现象的完整传递方程系统。本文讨论了扩散现象的能量信息模型,因为扩散过程是发生在生物选择元件中的过程的一般类型。这个模型描述了许多物理效应。它们被用于电化学生物传感器的概念设计。

An efficient environmental monitoring system adopting data fusion, prediction, & fuzzy logic 采用数据融合、预测和模糊逻辑的高效环境监测系统
Kostas Kolomvatsos, C. Anagnostopoulos, S. Hadjiefthymiades
Environmental monitoring plays an important role in the identification of abnormalities in the environment's characteristics. Abnormalities are related to negative effects that, consequently, heavily affect human lives. A number of sensors could be placed in a specific area and undertake the responsibility of monitoring environment's characteristics for specific phenomena. Sensors report back their measurements to a central system that is capable of situational reasoning. Accordingly, the system, through decision making, responds to any event related to the observed phenomena. In this paper, we propose a mechanism that builds on top of the sensors measurements and derives the appropriate decisions for the immediate identification of events. The proposed system adopts data fusion and prediction (time series regression) statistical learning methods for efficiently aggregating sensors measurements. We also adopt Fuzzy Logic for handling the uncertainty on the decision making on the derived alerts. We perform a set of simulations over real data and report on the advantages and disadvantages of the proposed system.
环境监测在识别环境特征异常方面起着重要的作用。异常与负面影响有关,因此严重影响人类生活。一些传感器可以放置在一个特定的区域,承担监测特定现象的环境特征的责任。传感器将它们的测量结果报告给一个能够进行情景推理的中央系统。因此,系统通过决策,对与观察到的现象有关的任何事件作出反应。在本文中,我们提出了一种建立在传感器测量之上的机制,并为立即识别事件派生出适当的决策。该系统采用数据融合和预测(时间序列回归)统计学习方法对传感器的测量数据进行有效的聚合。我们还采用模糊逻辑来处理衍生警报决策的不确定性。我们对实际数据进行了一组模拟,并报告了所提出系统的优点和缺点。

A generic scheme and a validation model for SON coordination in 5G networks 5G网络中SON协调的通用方案和验证模型
M. Stamatelatos, Aris Paraskevopoulos, A. Kaloxylos, N. Alonistioti
The ever-increasing heterogeneity of network elements, user devices, access technologies and services keeps posing requirements for the efficient management of infrastructures and resources. Autonomic network management is a promising paradigm but autonomic solutions are still far from being widely adopted, although self-organising capabilities have been introduced to network elements. The main reason for this is that autonomicity may raise serious trust and robustness issues. To address this, the need for appropriate coordination schemes is apparent. We propose a generic coordination scheme and a validation model which comes to verify that the desired correctness requirements are satisfied.
网元、用户设备、接入技术和服务的异构性日益增强,对基础设施和资源的高效管理提出了更高的要求。自主网络管理是一个很有前途的范例,但自主解决方案仍远未被广泛采用,尽管自组织能力已被引入网络元素。这样做的主要原因是,自主性可能会引发严重的信任和鲁棒性问题。为了解决这个问题,显然需要适当的协调计划。我们提出了一个通用的协调方案和一个验证模型来验证期望的正确性要求是否得到满足。
