A Method of Vulnerability Assessment Based on Deep Learning and OSS Fault Big Data 基于深度学习和OSS故障大数据的漏洞评估方法
Y. Tamura, H. Sone, Adarsh Anand, S. Yamada
Software vulnerability is generally defined as the weakness of security caused by the fault. Waterfall model has been usually used for the software development till recent past. Also, a number of open source components have been implemented in many commercial software. Recently, the open source software have extended to the cloud service and edge computing and the big data. It is thus imperetive to consider the impacts from the big data and network access. Various vulnerability assessment methods have been proposed by several researchers. In the typical vulnerability problems, methods of vulnerability assessment considering the fault factors have not been presented. Although, it is difficult to assess many fault factors recorded on the bug tracking system because of the uncertainty. The authors, in this paper, propose an assessment method of vulnerability by using the deep learning. Moreover, actual data to showcase the numerical examples for the estimation method of unknown parameters included in the proposed model for the vulnerability assessment have been presented.
软件漏洞通常被定义为由于故障而导致的安全弱点。直到最近,瀑布模型才被广泛应用于软件开发中。此外,许多开源组件已经在许多商业软件中实现。最近,开源软件已经扩展到云服务、边缘计算和大数据。因此,必须考虑大数据和网络接入带来的影响。不同的研究人员提出了不同的脆弱性评估方法。在典型的脆弱性问题中,尚未提出考虑故障因素的脆弱性评估方法。然而,由于不确定性的存在,很多记录在bug跟踪系统上的故障因素很难进行评估。本文提出了一种基于深度学习的脆弱性评估方法。并通过实际数据对所提出的模型中未知参数估计方法进行了数值算例验证。

A Hierarchical Graphical Model of Critical Success Factors for Implementing the UAE's Government Excellence 实施阿联酋卓越政府的关键成功因素的分层图形模型
O. AlZawati, Hamdi A. Bashir, I. Alsyouf
The study aims at identifying the key success factors of the government Excellence Model (GEM) that is implemented by the public sector of the United Arab Emirates (UAE). The GEM, specifically designed for public sector organizations, was launched by the UAE federal government in 2015 and was adopted by the Dubai Government Excellence Program in 2016. However, there are no studies made yet to identify its critical success factors (CSFs) to assure or augment its successful implementation. Hence, the objective of this study is to define and structure the CSFs that are affecting the implementation of the GEM. In this piece, 28 factors were identified through the literature and expert review from a UAE public sector organization. Interpretive structural modeling is used to understand the complex relationships and portray it in a simplified model. The result shows that “top management commitment” is a key success factor for implementing the GEM by the public sector. Sense of belonging and reputation have been found to be the ultimate factors resulting from the implementation of the GEM.
该研究旨在确定由阿拉伯联合酋长国(阿联酋)公共部门实施的政府卓越模式(GEM)的关键成功因素。创业板是专门为公共部门组织设计的,由阿联酋联邦政府于2015年启动,并于2016年被迪拜政府卓越计划采用。然而,目前还没有研究确定其关键成功因素,以确保或加强其成功实施。因此,本研究的目的是界定和架构影响创业板实施的基金。在这篇文章中,通过文献和阿联酋公共部门组织的专家审查确定了28个因素。解释结构建模是用来理解复杂的关系,并将其描绘成一个简化的模型。结果显示,“高层管理人员的承诺”是公营机构实施创业板的关键成功因素。归属感和声誉被发现是实施创业板的最终因素。

Quality Prediction Method by Modeling the Sustained Effects of Irregular Process Disturbances 基于非规则过程扰动持续效应建模的质量预测方法
Q. Xiu, M. Tanaka, M. Sakata
In manufacturing domain, there are increasing needs for quality control by utilizing various data collected from on-site. Machine failure, equipment component replacement, and other process disturbances are now collected by various sensors. The analysis of these data can help on-site managers to detect product quality drifts and to cope with them quickly and properly. However, the irregular and sparse nature of process disturbances causes prediction accuracy issue and modeling time issue. In this research, we propose a product quality prediction method using a stochastic process to model the irregular disturbances, and make prediction based on dense, regular matrix of sustained effects sampled from the stochastic process for modeling time reduction. As the result of applying the proposed quality prediction method to actual manufacturing data, the MSE (mean squared error) is reduced by 84.6% and the modeling time can be shortened to within 3 hours for daily update. Therefore, it can be estimated that our quality prediction method can help on-site managers to detect quality drifts at early stage and have a better control of product quality.
在制造领域,越来越需要利用现场收集的各种数据进行质量控制。机器故障、设备部件更换和其他过程干扰现在由各种传感器收集。对这些数据的分析可以帮助现场管理人员发现产品质量偏差,并快速、正确地处理它们。然而,过程扰动的不规则性和稀疏性导致了预测精度问题和建模时间问题。在本研究中,我们提出了一种利用随机过程对不规则扰动进行建模的产品质量预测方法,并基于从随机过程中采样的持续效应的密集规则矩阵进行预测,以减少建模时间。将所提出的质量预测方法应用于实际制造数据,MSE(均方误差)降低了84.6%,建模时间缩短到每天更新3小时以内。因此,可以估计,我们的质量预测方法可以帮助现场管理人员在早期发现质量漂移,更好地控制产品质量。

Lewen Bao, R. Miao, Bo Zhang, Ji-yue Zhou, Hao Hu
Under the background of sharing economy, in order to improve the utilization rate of vehicle resources and the economic benefits of operators for urban governance, this paper studies the dynamic pricing strategy to maximize the system utility. Firstly, the space-time distribution law, time-varying law and influencing factors of shared cars leased by users are analyzed, and the demand characteristics of users' travel are obtained; then, considering various factors such as operation mode, user acceptance, demand price elasticity and operation cost, the supply and demand balance of single-way electric rental vehicle system based on fixed network points is explored and the pricing strategies of each site in different periods are formulated. Finally, the feasibility of the model is verified by taking the ‘microbus’ electric rental vehicle project in Hangzhou City as an example. The research results can provide theoretical guidance for subsequent promotion and market allocation of urban governance.

Smart Product Service Requirements Identification and Evaluation: A Hybrid Method 智能产品服务需求识别与评估:一种混合方法
Z. Meng, Zhihua Chen, Zhao-Hui Sun, X. Ming
Identification and evaluation of smart product service requirements (SPSRs) are considered to be the critical steps for smart product service system (smart PSS) designing. However, there are few studies on the SPSRs identification and lack of service evaluation methods that comprehensively consider multiple uncertain factors. Therefore, this paper proposes a framework for SPSRs identification, which innovatively considers the characteristics of smart PSS and helps to elicit SPSRs from the logic of data value creation. Furthermore, considering the effects of individual semantic vagueness and individual subjective preference, a method based on the rough-fuzzy number is proposed, which helps service designers obtain subjective and accurate evaluation results. The case of the smart maintenance service of smart cars is used to prove the flexibility and feasibility of the identification and evaluation method.
智能产品服务需求的识别与评估是智能产品服务系统设计的关键环节。然而,目前国内外对特殊安全设施的识别研究较少,缺乏综合考虑多种不确定因素的服务评价方法。因此,本文提出了一个识别spsr的框架,该框架创新性地考虑了智能PSS的特征,有助于从数据价值创造的逻辑中引出spsr。在此基础上,考虑到个体语义模糊和个体主观偏好的影响,提出了一种基于粗糙模糊数的方法,帮助服务设计者获得主观、准确的评价结果。以智能汽车智能维修服务为例,验证了该识别评估方法的灵活性和可行性。

Improving the Strategic Distribution Performance of the Supply Chain of a Leading FMCG Company: A Case Study 一家领先快消品公司供应链战略分销绩效提升的案例研究
S. Mostafa, Y. Adel, K. Abdallah
Fast moving consumable goods require good supply chain operation. In this paper, a leading Egyptian FMCG is considered. The company wants to optimize its distribution network design considering several supply chain strategic objectives. The company wants to determine the number of warehouses to build, their sizes, customers assigned to each warehouse, and their layout. The objective is to reduce the distribution cost taking into consideration the company's strategic decision such as giving higher priority to important customers and assigning the nearest warehouse to each customer, and also the real live applicability of the suggested solution. We first segment the customer according to different strategic factors. Then a non-linear model is proposed for solving the problem. A hybrid heuristic is proposed that solves the problem by iterating between the optimal suggested location and the possible locations available for business in the real life according to availability and other strategic factors. Different layouts for the selected locations are evaluated using Monte-Carlo Simulation.
快速消费品需要良好的供应链运作。本文以埃及一家领先的快速消费品为研究对象。考虑到几个供应链战略目标,公司希望优化其分销网络设计。公司想要确定要建立的仓库的数量、仓库的大小、分配给每个仓库的客户以及仓库的布局。目标是考虑到公司的战略决策,如给予重要客户更高的优先级,为每个客户分配最近的仓库,以及建议的解决方案的实际适用性,从而降低配送成本。我们首先根据不同的战略因素对客户进行细分。在此基础上,提出了求解该问题的非线性模型。提出了一种混合启发式算法,根据可用性和其他战略因素,在最优建议位置和现实生活中商业可用的可能位置之间迭代来解决问题。使用蒙特卡罗模拟对选定位置的不同布局进行了评估。

In this paper, a leading Egyptian FMCG is considered. The company wants to optimize its distribution network design considering several supply chain strategic objectives. The company wants to determine the number of warehouses to build, their sizes, customers assigned to each warehouse, and their layout. The objective is to reduce the distribution cost taking into consideration the company's strategic decision such as giving higher priority to important customers and assigning the nearest warehouse to each customer, and also the real live applicability of the suggested solution. We first segment the customer according to different strategic factors. Then a non-linear model is proposed for solving the problem. A hybrid heuristic is proposed that solves the problem by iterating between the optimal suggested location and the possible locations available for business in the real life according to availability and other strategic factors.
