Defending all single connection failures for a particular system, segment routing issue, the switch will focus on the problems of selecting a small subset of trust-aware routing to improve the deep learning (DL). In the end, even if there were multiple path failures, these paths may introduce long-term, unnecessary overload in the proposed long short-term memory networks-based queuing routing segmentation (LSTM-QRS) experience of reducing traffic delays and adjusting traffic length by reducing network bandwidth. The critical factor is a novel traffic repair technique used to create a traffic repair path that switches to software-defined network (SDN) using multiple routing and providing additional flexibility in re-routing using long short-term memory networks (LSTM)-based queuing routing segment (LSTM-QRS) algorithms. It reduces the repair path length and recommends replacing the target-based traffic with the connection-based traffic fault detection router to avoid targeted traffic network congestion.
为了保护特定系统的所有单连接故障,分段路由问题,交换机将专注于选择一小部分信任感知路由以改进深度学习(DL)的问题。最后,即使存在多条路径故障,这些路径也可能在建议的基于长短期内存网络的排队路由分段(LSTM-QRS)体验中引入长期的、不必要的过载,通过减少网络带宽来减少流量延迟和调整流量长度。关键因素是一种新的交通修复技术,用于创建交通修复路径,该路径使用多个路由切换到软件定义网络(SDN),并使用基于长短期记忆网络(LSTM)的排队路由段(LSTM- qrs)算法在重新路由时提供额外的灵活性。减少修复路径长度,建议使用基于连接的流量故障检测路由器替换目标流量,避免目标流量网络拥塞。

The rich spectral and spatial information of hyperspectral images are well known in the literature. The higher dimensionality of HSI creates Hughes's effect and increased computational complexity. This demands reduction for HS images as a pre-processing step. The necessary reduction of bands can be achieved by a proper band selection (BS) technique. The proposed features based unsupervised BS technique follows three subsequent steps: 1) for each band image statistical features are extracted, 2) bands are clustered with a k-means approach using the extracted features, 3) each cluster is ranked using mean entropy measure, 4) bad clusters are removed, and 5) for each selected cluster, a representative band is selected. The proposed method is validated over three widely used standard datasets and six state-of-the-art approaches using an ensemble of binary SVM classifiers. The obtained results strongly suggest the clustering is essential to reduce the redundancy, and removal of cluster is informative to keep the informative bands.
高光谱图像丰富的光谱信息和空间信息在文献中是众所周知的。HSI的高维产生了休斯效应,增加了计算复杂度。这就要求在预处理步骤中对HS图像进行压缩。通过适当的波段选择(BS)技术可以实现必要的波段减少。本文提出的基于特征的无监督BS技术分为三个步骤:1)提取每个波段的图像统计特征,2)使用提取的特征使用k-means方法对波段进行聚类,3)使用平均熵度量对每个聚类进行排序,4)去除不良聚类,5)为每个选择的聚类选择一个具有代表性的波段。该方法在三个广泛使用的标准数据集和六种最先进的方法上进行了验证,这些方法使用了二值支持向量机分类器的集合。结果表明,聚类是减少冗余的关键,去除聚类是保留信息带的重要手段。

Review of Association Mining Methods for the Extraction of Rules Based on the Frequency and Utility Factors 基于频率和效用因子的规则提取关联挖掘方法综述
Pub Date : 2021-10-01 DOI: 10.4018/IJITPM.2021100101

Association rule defines the relationship among the items and discovers the frequent items using a support-confidence framework. This framework establishes user-interested or strong association rules with two thresholds (i.e., minimum support and minimum confidence). Traditional association rule mining methods (i.e., apriori and frequent pattern growth [FP-growth]) are widely used for discovering of frequent itemsets, and limitation of these methods is that they are not considering the key factors of the items such as profit, quantity, or cost of items during the mining process. Applications like e-commerce, marketing, healthcare, and web recommendations, etc. consist of items with their utility or profit. Such cases, utility-based itemsets mining methods, are playing a vital role in the generation of effective association rules and are also useful in the mining of high utility itemsets. This paper presents the survey on high-utility itemsets mining methods and discusses the observation study of existing methods with their experimental study using benchmarked datasets.
关联规则定义项目之间的关系,并使用支持-置信度框架发现频繁项目。该框架用两个阈值(即最小支持度和最小置信度)建立用户感兴趣的或强关联规则。传统的关联规则挖掘方法(即先验和频繁模式增长[FP-growth])被广泛用于频繁项集的发现,这些方法的局限性在于它们在挖掘过程中没有考虑项的利润、数量或成本等关键因素。电子商务、市场营销、医疗保健和网络推荐等应用程序由具有效用或利润的项目组成。在这种情况下,基于效用的项集挖掘方法在有效关联规则的生成中起着至关重要的作用,并且在高效用项集的挖掘中也很有用。本文介绍了高效用项目集挖掘方法的概况,并讨论了现有方法的观察研究及其使用基准数据集的实验研究。

This research proposed optimization models for task scheduling and sequencing in work-intensive multiple projects under normal and unexpected events. The objectives of scheduling model were minimizing the total overtime/under-time costs and maximizing satisfaction values on tasks due dates and processing standard times. Further, the sequencing model aimed to minimize the sum of tasks' start times, maximize resource utilization, and maximize satisfaction on project completion times. Illustrations of the proposed scheduling and sequencing optimization models were provided where the results showed effective scheduling and sequencing of project tasks at minimal costs and achieved the desired satisfaction levels on tasks and projects and significantly enhanced resource efficiency at minimal overtime and under-time costs. Further, optimization models were modified to deal with unexpected events. In conclusion, the proposed models may support project managers in planning project tasks in a cost-effective manner under normal and unexpected events.

Shared Leadership: Towards a Theoretical Moderation Framework in Information Systems Project Teams 共享领导:迈向信息系统项目团队的理论调节框架
Pub Date : 2021-07-01 DOI: 10.4018/IJITPM.2021070104

Shared leadership refers to an emergent, collective team process where leadership is distributed among and stems from team members, rather than a single designated leader. While shared leadership has gained considerable attention in the literature in recent years, it has received little attention in information systems (IS) project teams. In this study, a theoretical moderation framework in IS project teams that portrays the positive relationship between shared leadership and IS project success is presented. Moreover, project-centered moderators (i.e., project complexity and project task interdependence) and team-centered moderators (i.e., team autonomy and team supportive culture) have been proposed to influence the shared leadership-IS project success relationship. This study proposes that this relationship is stronger when projects are more complex and more interdependent, and when teams have a higher level of autonomy and supportive culture.
共享领导指的是一种突发的、集体的团队过程,在这种过程中,领导力被分配给团队成员,并源于团队成员,而不是一个指定的领导者。虽然共享领导近年来在文献中获得了相当大的关注,但在信息系统(IS)项目团队中却很少受到关注。在本研究中,提出了一个理论调节框架,描述了共享领导与信息系统项目成功之间的积极关系。此外,研究还提出了以项目为中心的调节因子(即项目复杂性和项目任务相互依赖)和以团队为中心的调节因子(即团队自主性和团队支持性文化)对共享领导-信息系统项目成功关系的影响。这项研究提出,当项目更复杂、更相互依赖、团队拥有更高水平的自主权和支持性文化时,这种关系就会更强。

Using evolutionary perspective of gossip and knowledge-based view, the study proposes knowledge sharing behaviour as the underlying mechanism that helps in establishing the relationship between positive workplace gossip and success of IT projects. The study used multi-source and multi-layered data collection technique; data were collected from 304 employees working in information technology (IT) projects within Pakistan. The study used peer reports for knowledge sharing behaviour, while gossip and project success were self-reported. Results of the study show that positive workplace gossip has a positive relation with project success. The study also found support of partial mediation of knowledge sharing behaviour between positive workplace gossip and project success. These results have crucial implications for policy makers and project managers of IT projects. The findings reveal the importance of informal social networks of project team members towards project success. Managers shall device such mechanisms that allow for propagation of informal networks and knowledge sharing. Keywords Critical Success Factors, Information Technology Projects, Knowledge Sharing Behaviour, Positive Workplace Gossip, Project Success.
本研究运用八卦的进化视角和知识基础观点,提出知识共享行为是建立积极职场八卦与IT项目成功之间关系的潜在机制。本研究采用多源、多层次数据采集技术;数据收集自巴基斯坦境内从事信息技术(IT)项目的304名员工。该研究使用同伴报告来记录知识分享行为,而八卦和项目成功则是自我报告。研究结果表明,积极的职场八卦与项目成功呈正相关。研究还发现,在积极的职场八卦和项目成功之间,知识分享行为存在部分中介作用。这些结果对IT项目的政策制定者和项目经理具有至关重要的意义。研究结果揭示了项目团队成员的非正式社会网络对项目成功的重要性。管理者应该设计这样的机制,允许非正式网络的传播和知识共享。关键成功因素,信息技术项目,知识分享行为,积极职场八卦,项目成功。

Complexity is ubiquitous in modern engineering and project management. It is traditionally associated with failure. Also, complexity works! It delivers functionality, creativity, innovation. Complexity management contributes to the success of high-risk IT projects, helps better project understanding, allows for better prioritization and planning of resources. Managing negative complexity reduces project risk. Positive and appropriate complexity are catalysts for opportunities. This paper is a qualitative longitudinal study based on multiple industry project cases, consisting in the repeated evaluation of a set of complexity management tools. The tools were deployed in a classical process framework: plan, identify, analyze, plan responses, monitor, and control. The evaluated tools red-flag and measure complexity, analyze its sources and effects, and plan mitigation strategies. The study aims to provide project managers with methods for increasing project success rates and reducing failure in complex IT project environments.

The common view of requirements engineering consists of requirement elicitation, specification, validation, and evolution. Requirement elicitation is a significant stage to assure the quality of the requirement documentations and would affect the project success or failure. There are different techniques to elicit the requirements. Each technique has its advantages and disadvantages. Thus, it is important to adopt more than one kind of technique to describe a system clearly from different viewpoints. This study prospected some of the research papers in the same field to display the requirements elicitation techniques that are used in developing mobile applications from a variety of research disciplines. It suggests some requirements elicitation concepts to guide software engineers in selecting the techniques according to customers' needs and to show the common challenges that they face.
需求工程的常见观点包括需求引出、规格说明、验证和进化。需求提取是保证需求文档质量的重要阶段,将影响到项目的成败。有不同的技术来引出需求。每种技术都有其优点和缺点。因此,采用一种以上的技术来从不同的角度清晰地描述系统是很重要的。本研究对同一领域的一些研究论文进行了展望,以展示各种研究学科中用于开发移动应用程序的需求引出技术。提出了一些需求启发的概念,以指导软件工程师根据客户的需求选择技术,并显示他们所面临的共同挑战。

This study prospected some of the research papers in the same field to display the requirements elicitation techniques that are used in developing mobile applications from a variety of research disciplines. It suggests some requirements elicitation concepts to guide software engineers in selecting the techniques according to customers' needs and to show the common challenges that they face.","PeriodicalId":375999,"journal":{"name":"Int.

Project manager (PM) certification and other commonly-tested independent factors were deductively examined using logistic regression to develop an explanatory model of high-priced public procurement project success versus failure. Overall 59% were successful, and 41% failed. The model correctly classified 67.3% of the 2,692 projects, yielding a significant 12% effect size. Individual factors, PM experience, certification, and contractor quality, impacted performance, but contractor size, revenue, industry type, PM age, gender, and education had negligible effect on performance. Quality was in the opposite hypothesized direction. Certified PMs were more likely to achieve successful projects rather than encounter failures. Future research advice was offered.
项目经理(PM)认证和其他常用的独立因素使用逻辑回归进行演绎检验,以开发高价公共采购项目成功与失败的解释模型。总的来说,59%成功,41%失败。该模型正确分类了2692个项目中的67.3%,产生了显著的12%的效应值。个人因素,项目经理经验,认证和承包商质量,影响绩效,但承包商规模,收入,行业类型,项目经理年龄,性别和教育对绩效的影响可以忽略不计。质量与假设的方向相反。经过认证的项目经理更有可能实现成功的项目,而不是遇到失败。提出了未来研究的建议。
