Smart Society and Artificial Intelligence:Big Data Scheduling and the Global Standard Method Applied to Smart Maintenance

The implementation of artificial intelligence(AI)in a smart society,in which the analysis of human habits is mandatory,requires automated data scheduling and analysis using smart applications,a smart infrastructure,smart systems,and a smart network.In this context,which is characterized by a large gap between training and operative processes,a dedicated method is required to manage and extract the massive amount of data and the related information mining.The method presented in this work aims to reduce this gap with near-zero-failure advanced diagnostics(AD)for smart management,which is exploitable in any context of Society 5.0,thus reducing the risk factors at all management levels and ensuring quality and sustainability.We have also developed innovative applications for a humancentered management system to support scheduling in the maintenance of operative processes,for reducing training costs,for improving production yield,and for creating a human–machine cyberspace for smart infrastructure design.The results obtained in 12 international companies demonstrate a possible global standardization of operative processes,leading to the design of a near-zero-failure intelligent system that is able to learn and upgrade itself.Our new method provides guidance for selecting the new generation of intelligent manufacturing and smart systems in order to optimize human–machine interactions,with the related smart maintenance and education.

Acupoint Selection Standards of Auricular Therapy in the Treatment of Maintenance Hemodialysis Insomnia Based on Data Mining

Background:Insomnia is a high-incidence complication in patients undergoing maintenance hemodialysis(MHD).Auricular therapy can effectively improve sleep with few adverse effects.Acupoint selection affects the impact of auricular therapy.However,there is currently a lack of analysis on the standards of acupoint selection.Our study used data mining technology to investigate the acupoint selection principles and characteristics of auricular therapy for the treatment of MHD-related insomnia.Objective:The objective of the study is to explore the standards of acupoint selection in auricular therapy for the treatment of MHD-related insomnia through data mining technology.Materials and Methods:We searched three English(PubMed,WOS,and Embase)and four Chinese(CNKI,VIP,Wangfang,and CBM)databases for studies on auricular therapy for MHD-related insomnia from self-establishment to November 14,2022.Results:Eighty-one publications were involved,which included 33 acupoints.The most common auricular points in patients with MHD-related insomnia were the Shenmen,heart,and kidney points.More applications involved the visceral,nervous system,and specific acupoints.Five effective clusters and two clusters were obtained through cluster analysis,including specific auricular points for insomnia,such as the multi-dream area,neurasthenia area,deep sleep point,and anterior ear lobe.Complex network analysis showed that the core auricular acupoint combinations for the intervention of MHD-related insomnia were Shenmen with kidney,Shenmen with heart,heart with kidney,heart with Shenmen,and heart and Shenmen with subcortex.Conclusions:The selection of auricular points for the treatment of MHD-related insomnia was guided by the heart theory of traditional Chinese medicine.Clinical treatment attaches importance to the use of the multi-dream area,neurasthenia area,and other acupoints.

A Critical Examination of the European Standard EN 1504 ＂Products and Systems for Protection and Repair of Concrete Structures＂

The European Standard EN 1504 ＂Products and systems for protection and repair of concrete structures -- Definitions, requirements, quality control and evaluation of conformity＂ can be considered a real milestone for the companies involved in the rehabilitation of buildings, bridges, piers, pipelines, and other civil or industrial concrete structures. However in some cases the examination and, even more, the practical application of the proposed guidelines are made difficult by a complicated sub-division in principles and methods, and by a confusing and repetitive layout. The paper deals in particular with the principles and methods for the rehabilitation of concrete damage due to reinforcement corrosion, often strictly connected, anyway, to those adopted in order to rehabilitate the concrete itself. Suggestions are given for a possible future update of the Standard, based on the personal experience of the Authors.

Comparison of Traffic Growth Factors in Three Major Highways of Bangladesh： A Case Study

The unanticipated increase in vehicle population and heavy axle loads has brought the road network of Bangladesh to a crumbling stage. The network is grossly short of its structural capacity, highly distressed and has started showing signs of premature failure. The RHD （Roads and Highways Department） of Bangladesh uses 8%-10% growth rate of traffic for structural design of these highways that need to be upgraded due to present high traffic volume demand. An attempt has been made through this case study, by using traffic flow data from different computerized toll plaza established in recent times, to predict traffic growth pattern of different highways of Bangladesh. The toll collectors of different computerized toll plaza have been recording and preserving round-the-year continuous flow data in a systematic manner. The study has taken this prospect of utilizing several years of flow data along Dhaka-Chittagong Highway （N-1）, Dhaka-Sylhet Highway （N-2）, Dhaka-North Bengal Highway （N-5） and found the traffic growth factor of 21.03%, 23.79% and 11.31%, respectively, which is much higher than that transport authority of Bangladesh is currently using. By the use of accurate traffic engineering parameters such as traffic growth factors, it is possible to resist frequent distress of pavement and sustainable pavement management can be implemented by RHD.

A generic framework for qualifications of digital twins in maintenance

Digital twins have emerged as a promising technology for maintenance applications,enabling organizations to simulate and monitor physical assets to improve their performance.In Operation and Maintenance(O&M),digital twin facilitates the diagnosis and prognosis of critical assets,forming the basis for smart maintenance planning and reducing downtime.However,there is a lack of standardized approaches for the qualifications of digital twins in maintenance,leading to low trustworthiness and limiting its application.This paper proposes a novel framework for the qualifications of digital twins in maintenance based on five pillars,namely fidelity,smartness,timeliness,integration,and standard compliance.We demonstrate the effectiveness of the framework through two case studies,showing how it can be implemented on digital twins for preventive maintenance and condition-based maintenance.Our proposed framework can help organizations across different industrial domains develop and implement digital twins in maintenance more effectively and efficiently,leading to significant benefits in terms of cost reduction,performance improvement,and sustainability.

基于三级养护标准的沥青路面预养护方案多目标加权灰靶决策

针对沥青路面最佳预防性养护策略选择问题,结合关于沥青路面预防性养护指标及规范标准,建立了基于判断性指标、综合性指标和控制性指标的三级预防性养护判断标准。在此标准下,以多年度项目级养护规划为研究对象,结合GM(1,1)预测模型确定预防性养护时段,并引入多目标智能加权灰靶决策模型对适用性预防性养护方案进行优化决策。在此过程中,确定了养护费用、耐久性等8个养护目标并利用博弈论组合赋权法确定权重,选取G30连霍高速甘肃省境内某路段进行决策分析。结果表明:该路段最早需要开展预防性养护的时间为第3年,在第6年底之后不宜再实施预防性养护,在该预防性养护时段内,方案4的综合效益值最大,其值为0.735 8,即应在第4年采取超薄层罩面预养护措施。该方法简单实用,可成为沥青路面预防性养护策略选择的一种新方法。

数字经济下个人信息使用和保护平衡的三方演化博弈分析

构建以政府(G)、个人信息所有者(P)和个人信息获取/使用者(C)三方为主体的动态博弈模型,分析其演化过程。通过对以政府为驱动的三方博弈的演化路径分析,从三方的角度分别提出对策建议。研究结果表明,政府实施严格监管可以提升自身形象和管理效率。政府应主要采用惩罚手段,使个人信息获取/使用者在违规策略下产生较高的成本,从而促使他们采取规范获取和使用的策略。对于个人信息所有者而言,政府及时发现违规行为并严格处理,同时积极宣传个人信息维护,可激励他们采取积极提供个人信息的策略。在这种情况下,三方可实现帕累托最优的策略均衡,并实现在数字经济下个人信息使用和保护的平衡。

粉沙质海岸航道运维期骤淤防治标准研究

黄骅港处于淤泥粉沙质海岸,港区航道的骤淤防治重现期为10年。黄骅港煤炭港区建成20余年来,其吞吐量逐年增加,作为煤炭枢纽港的重要性进一步凸显。煤炭港区航道进入运维期后,疏浚维护力量得到加强,航道淤积特点也发生一定变化,泥沙淤积资料进一步完善,航道骤淤防治标准具备进一步提升的条件,以加强航道抗风险能力。本文通过对泥沙淤积实测数据的分析,提出除防治航道一次大风骤淤外,需关注连续多频次低重现期大风骤淤,其造成的累加骤淤量不可忽视。根据环境条件变化及淤积特点,提出了黄骅港煤炭港区航道运维期骤淤防治标准,可作为航道备淤深度确定依据,以及其他粉沙质海岸航道运维期骤淤防治标准确定的参考。
