A knowledge hiding approach to cope with COVID-19: A Comparison between Spain and China 应对新冠肺炎的知识隐藏方法:西班牙与中国的比较
J. Cegarra-Navarro, Elena-Mădălina Vătămănescu, Aurora Martínez‐Martínez
Although it is not clear what positive and negative effects knowledge hiding may have on citizens, some Governments have tried to address the crisis caused by COVID-19 through hiding or distorting information available to citizens. This study suggests that the presence of realized absorptive capacity (RACAP) allows citizens to stop the spreading of fake news about COVID 19. The paper focuses on RACAP as a method to counteract the potential negative effects of knowledge hiding and thus increase citizen engagement. To do so, this study analyses data collected from 251 citizens of two countries: Spain and China. Results provides evidence that while Spaniards have the feeling that a lot of information has been hidden from them, Chinese citizens are ultimately much more committed to taking appropriate COVID 19 measures. Despite these differences, in both samples RACAP help to ensure compliance with new legislation and COVID-19-related restrictions.
虽然目前尚不清楚隐藏知识可能对公民产生的积极和消极影响,但一些政府试图通过隐藏或扭曲公民可获得的信息来应对COVID-19造成的危机。该研究表明,实现吸收能力(RACAP)的存在可以让公民阻止有关COVID - 19的假新闻的传播。本文将RACAP作为一种抵消知识隐藏潜在负面影响的方法,从而提高公民参与度。为此,这项研究分析了来自西班牙和中国两个国家的251名公民的数据。调查结果表明,虽然西班牙人觉得很多信息被隐瞒了,但中国公民最终更愿意采取适当的新冠措施。尽管存在这些差异,但在这两个样本中,RACAP有助于确保遵守新的立法和与covid -19相关的限制。

Data Science Roadmapping: Towards an Architectural Framework 数据科学路线图:走向架构框架
Kerem Kayabay, M. Gökalp, E. Gökalp, P. Eren, Altan Koçyiğit
The availability of big data and related technologies enables businesses to exploit data for competitive advantage. Still, many industries face obstacles while leveraging data science to overcome business problems. This paper explores the development of a roadmapping approach to address data science challenges. Towards this goal, we customize technology roadmapping by synthesizing roadmapping, big data, data science, and data-driven organization literature. The resulting data science roadmapping approach links business strategy with data-related, technological, and organizational resources. It also enables communication, stakeholder buy-in, and project prioritization. While most of the existing studies illustrate prebuilt roadmaps, this study focuses on the process of roadmapping. The application of the roadmapping process rather than a particular roadmap provides the benefits above.
大数据和相关技术的可用性使企业能够利用数据获得竞争优势。尽管如此,许多行业在利用数据科学来克服业务问题时仍面临障碍。本文探讨了解决数据科学挑战的路线图方法的发展。为了实现这一目标,我们通过综合路线图、大数据、数据科学和数据驱动组织文献来定制技术路线图。由此产生的数据科学路线图方法将业务战略与数据相关的、技术的和组织的资源联系起来。它还支持沟通、涉众参与和项目优先级划分。虽然大多数现有研究都说明了预先构建的路线图,但本研究侧重于路线图绘制的过程。应用路线图过程而不是特定的路线图可以提供上述好处。

Growth of Digital Supply Chains for SME Transformation 数字化供应链助力中小企业转型
Sarath Menon, Satya Shah
Over the past years supply chain has undergone a massive change, from operational function which reported to sales or manufacturing which then focused on ensuring the supply of production lines and delivery to customers, to an independent supply chain management team which is led by Chief Supply Chain Officer in some organisation. Industry 4.0 and their innovative technologies has created a disruption which requires the organisations to redesign their supply chain. Emergence of the industry 4.0 has paved the way for next level of supply chain- Digital Supply Chain. Global market leading manufacturers has positioned themselves with the world of supply chain 4.0 to meet the expectation of their end customers. Small and Medium Enterprises (SME's) plays has major role in supporting the global market leaders. But SME's lacks the knowledge of significance of digitalising themselves with the extremely complex supply chain 4.0 which may lead them to losses and closures if they do not transform themselves with the latest innovative technologies and adopt digital supply chain (DSC). This paper aims to review the current literatures on digital supply chain to gain insight of current status of relevant literatures which focus on Digital transformation of supply chain within manufacturing SME's.
在过去的几年里,供应链经历了巨大的变化,从运营功能报告到销售或制造,然后专注于确保生产线的供应和交付给客户,到一个独立的供应链管理团队,由一些组织的首席供应链官领导。工业4.0及其创新技术带来了颠覆性变革,要求企业重新设计其供应链。工业4.0的出现为下一阶段的供应链——数字化供应链铺平了道路。全球市场领先的制造商已经将自己定位于供应链4.0的世界,以满足其最终客户的期望。中小企业在支持全球市场领导者方面发挥着重要作用。但中小企业缺乏对极其复杂的供应链4.0数字化的重要性的认识,如果他们不利用最新的创新技术改造自己并采用数字供应链(DSC),他们可能会导致亏损和倒闭。本文旨在通过对数字化供应链相关文献的梳理,了解制造业中小企业供应链数字化转型的相关文献现状。

Assessing the role of knowledge management to enhance or prevent digital transformation in SMEs: critical knowledge factors required 评估知识管理在促进或阻止中小企业数字化转型中的作用:所需的关键知识因素
Alessia Zoppelletto, L. B. Orlandi, A. Zardini, C. Rossignoli
The 4th industrial revolution or Knowledge Age enhances the transition to knowledge-driven organizations that rely on data, technologies and learn how to manage all the variables involved in their digital transformation (DT). How should firms manage their knowledge during their DT is an underdeveloped research issue, especially in the SMEs' context. Employing a mixed inductive-deductive approach, this multiple case-study of 35 SMEs tries to shed light on which are the critical knowledge factors required to support and hinder DT in SMEs' context.

Exploring the concept of “knowledge sabotage” “知识破坏”概念探析
Alberto Ferraris, Francesco Antonio Perotti
The purpose of this short paper is to build theory and to stimulate further research on knowledge sabotage, the most extreme counterproductive behavior that hinders knowledge sharing. Following a comprehensive analysis of the literature, we identified nine original conceptual propositions which shape an innovative framework of individual-, group- and organizational-level factors. The proposed framework offers the key factors that are relevant for a better conceptualization of knowledge sabotage, thus representing a fertile ground for new empirical studies. Since the recent formalization of the "sabotage" of knowledge, this paper is the first that presents such influencing factors thus opening the way for a better understanding of the dynamics that inhibit knowledge sharing.
这篇短文的目的是建立理论,并促进对知识破坏的进一步研究,知识破坏是阻碍知识共享的最极端的反生产行为。在对文献进行全面分析之后,我们确定了九个原始的概念命题,它们形成了个人、群体和组织层面因素的创新框架。提出的框架提供了与更好地概念化知识破坏相关的关键因素,从而为新的实证研究提供了肥沃的土壤。自从最近对知识“破坏”的形式化以来,本文首次提出了这种影响因素,从而为更好地理解抑制知识共享的动态开辟了道路。

Mathematical modeling and multi-agents approach for the evolution of the Coronavirus pandemic 冠状病毒大流行演变的数学建模和多agent方法
Rajaa Aboulaich, K. Bensaid, S. Chabbar, Jaafar El Karkri
The objective of this work is to simulate the growth of the novel corona virus disease in some cities in Morocco. We study the impact of the barrier and health measures to be taken to reduce the spread and contain the epidemic. In order to define the optimal measures to take to curb the spread of the pandemic, our goal is to use adequate mathematical modeling tools and adapt agent-based models to simulate the evolution of the pandemic and its spread in Morocco. An analysis of the disease spread based on compartmental modeling leads to an ordinary differential equation governing the system. In addition, the agent-based approach uses artificial intelligence and makes it possible to deal with complexity, also permits to consider different scenarios. The obtained numerical simulations give a clear idea of the spread of a party’s disease and for each of the measures that are taken into account during containment or during de-containment. These simulations are decision support efficient tools rendered on powerful modeling tools. The two approaches are complementary and give rise to successful models.
这项工作的目的是模拟摩洛哥一些城市新型冠状病毒病的发展。我们研究了屏障的影响以及为减少传播和控制疫情而应采取的卫生措施。为了确定遏制该流行病蔓延的最佳措施,我们的目标是使用适当的数学建模工具并调整基于主体的模型,以模拟该流行病的演变及其在摩洛哥的蔓延。基于区室模型的疾病传播分析导致控制系统的常微分方程。此外,基于代理的方法使用人工智能,使得处理复杂性成为可能,也允许考虑不同的场景。所获得的数值模拟可以清楚地了解缔约方疾病的传播情况,以及在控制或去控制期间所考虑的每一项措施。这些模拟是在强大的建模工具上呈现的决策支持有效工具。这两种方法是互补的,并产生成功的模式。

Strategic DDMRP’s Buffer Positioning for hybrid MTO/MTS manufacturing MTO/MTS混合制造的战略性DDMRP缓冲定位
Abdelhalim Achergui, H. Allaoui, T. Hsu
To make a product, many components: made inside a supply chain or provided by external suppliers, may be needed as specified in the bill of material (BOM). This variety exposes the production process to various risks as stock ruptures for instance. Due to companies efforts to face the volatile demand and market pressure, Work-in-process (WIP) inventories become redundant in flow production lines. Uncertainty became a major flaw of the system, to which many methods were developed and adopted to manage and optimize the use of resources. One of the most recent methods is Demand Driven Material Requirement Planning (DDMRP) that uses buffers: visual indicators of the net flow integrating the real stock, the actual demand and the expected provisions; This paper describes an approach to solve the optimization problem of minimizing the storing costs, under service time constraint for uncapacitated buffer positioning alongside with the buffer allocation following the DDMRP planning methodology in a hybrid MTO/MTS manufacturing system. Finally, numerical examples are applied to test the efficiency and the performance of the developed algorithm.
为了制造一个产品,可能需要在物料清单(BOM)中指定的许多组件:在供应链中制造或由外部供应商提供。这种变化使生产过程面临各种风险,例如库存破裂。由于企业努力面对不稳定的需求和市场压力,在制品(WIP)库存在流水生产线上变得多余。不确定性成为该系统的主要缺陷,为此开发和采用了许多方法来管理和优化资源的使用。最近的一种方法是需求驱动的物料需求计划(DDMRP),它使用缓冲:净流量的可视化指标,包括实际库存,实际需求和预期供应;本文描述了一种基于DDMRP规划方法的混合MTO/MTS制造系统中,在服务时间约束下,无能力缓冲区定位与缓冲区分配的存储成本最小化优化问题的解决方法。最后,通过数值算例验证了该算法的有效性和性能。

Supervised depth estimation for visual perception on low-end platforms 低端平台视觉感知的监督深度估计
Sabri Abderrazzak, Souissi Omar, Bouyahyaoui Abdelmalik
Depth estimation is a very useful task in robotics and mostly computervision applications as obstacle avoidance, navigation and localization in GPS denied environments. Stereovision aproaches are commonly used in the state-of-the-art and dominated with methods from the classic Euclidean geometryand computational photography. However, most of these methods are computationally expensive which limits the applicability on high end setups and platforms. In the light of the recent bloom in Deep Learning and especially CNNs, we present in this paper a lightweight CNN-based encoder-decoder model for the task of monocular depth estimation from single RGB images. The model is designed to be runnable on low-cost platforms. In particular, we explore the performance of the most recent version of the MobileNet family as an encoder part, and afterwards we gradually build up the depth map back using the optimized UpConv block for decoding.
深度估计在机器人和大多数计算机视觉应用中是一项非常有用的任务,如在GPS拒绝环境中避障、导航和定位。立体视觉方法通常用于最先进的技术,并以经典的欧几里得几何和计算摄影的方法为主。然而,这些方法中的大多数在计算上都很昂贵,这限制了它们在高端设置和平台上的适用性。鉴于最近深度学习特别是cnn的蓬勃发展,我们在本文中提出了一个轻量级的基于cnn的编码器-解码器模型,用于从单个RGB图像进行单目深度估计。该模型被设计为可在低成本平台上运行。特别是,我们探索了MobileNet家族最新版本作为编码器部分的性能,然后我们逐渐使用优化的UpConv块构建深度图进行解码。

In particular, we explore the performance of the most recent version of the MobileNet family as an encoder part, and afterwards we gradually build up the depth map back using the optimized UpConv block for decoding.","PeriodicalId":158303,"journal":{"name":"2020 IEEE International Conference on Technology Management, Operations and Decisions (ICTMOD)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122233214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep Learning Framework for Forecasting Tourism Demand 旅游需求预测的深度学习框架
Houria Laaroussi, F. Guerouate, M. Sbihi
Accurate Tourism demand forecasting plays an important role to make decision and plan policy. However, tourism demand is characterized by complexity and non-linearity. Traditional tourism demand forecasting techniques are Linear methods and unable to fully simulate the nonlinear characteristics of tourism demand. Deep learning (DL) methods can be a promising solution to achieve an accurate forecast. These models are able to evaluate the non-linear relationship, without the drawbacks of Time Series and econometric models. In this paper, a deep learning Models are proposed to accurately predict tourist arrivals for Morocco from 2010 to 2019. The proposed framework uses a long short-term memory (LSTM) and gated recurrent unit (GRU). Experiments demonstrate that the LSTM and GRU methods perform better than support vector regression (SVR) and artificial neural network models (ANN).
准确的旅游需求预测对旅游决策和政策规划具有重要作用。然而,旅游需求具有复杂性和非线性的特点。传统的旅游需求预测技术多为线性方法,无法充分模拟旅游需求的非线性特征。深度学习(DL)方法可以是一个有前途的解决方案来实现一个精确的预测。这些模型能够评估非线性关系,没有时间序列和计量经济模型的缺点。本文提出了一种深度学习模型来准确预测2010年至2019年摩洛哥的游客人数。该框架采用长短期记忆(LSTM)和门控循环单元(GRU)。实验表明,LSTM和GRU方法优于支持向量回归(SVR)和人工神经网络模型(ANN)。
