Framework based on building information modeling, mixed reality, and a cloud platform to support information

Berardo NATICCHIA, Alessandra CORNELI, Alessandro CARBONARI

《工程管理前沿(英文)》 2020年 第7卷 第1期   页码 131-141 doi: 10.1007/s42524-019-0071-y

摘要: The quality of information flow management has a remarkable effect on the entire life cycle of buildings. Manual retrieval of technical specifications and features of building components and their performance assessment leads to increased cost and time and efficiency reduction, especially during the facility management (FM) stage. The introduction of building information modeling (BIM) in the construction industry can provide a valuable means of improving the organization and exchange of information. BIM tools integrate multiple levels of information within a single digital model of a building. Nevertheless, the support given by BIM to FM is far from being fully effective. Technicians can benefit from real-time communication with the data repository whenever the need for gathering contextual information and/or updating any data in the digital model arises. The framework proposed in this study aims to develop a system that supports on-site operations. Information requirements have been determined from the analyses of procedures that are usually implemented in the building life cycle. These studies set the standard for the development of a digital model of a building, which will be shared among various actors in charge of FM and accessed via a cloud platform. Moreover, mixed reality is proposed to support specific information that is relevant to geometric features and procedures to be followed by operators. This article presents three use-cases supported by the proposed framework. In addition, this research article describes the first proof of concept regarding real-time support for FM.

New method of fault diagnosis of rotating machinery based on distance of information entropy

Houjun SU, Tielin SHI, Fei CHEN, Shuhong HUANG

《机械工程前沿(英文)》 2011年 第6卷 第2期   页码 249-253 doi: 10.1007/s11465-011-0124-3

摘要:

This paper introduces the basic conception of information fusion and some fusion diagnosis methods commonly used nowadays in rotating machinery. From the thought of the information fusion, a new quantitative feature index monitoring and diagnosing the vibration fault of rotating machinery, which is called distance of information entropy, is put forward on the basis of the singular spectrum entropy in time domain, power spectrum entropy in frequency domain, wavelet energy spectrum entropy, and wavelet space feature entropy in time-frequency domain. The mathematic deduction suggests that the conception of distance of information entropy is accordant with the maximum subordination principle in the fuzzy theory. Through calculation it has been proved that this method can effectively distinguish different fault types. Then, the accuracy of rotor fault diagnosis can be improved through the curve chart of the distance of information entropy at multi-speed.

Owner-dominated building information modeling and lean construction in a megaproject

Mingyue LI, Zhuoling MA, Xi TANG

《工程管理前沿(英文)》 2021年 第8卷 第1期   页码 60-71 doi: 10.1007/s42524-019-0042-3

摘要: The integration of building information modeling (BIM) and lean construction (LC) provides a solution for the management of megaprojects. Previous studies have generally focused on the theoretical or empirical adoption of BIM and LC. Moreover, only a few studies have examined the approach of simultaneously using BIM and LC in megaprojects. Therefore, an intensive study on the application of BIM and LC in megaprojects, particularly to explore considerably effective integrated application modes of BIM and LC in megaprojects, will substantially promote the management efficiency of megaprojects. The current study describes a method that integrates owner-dominated BIM and LC that was developed in a case study. The proposed method provides a framework for all stakeholders to use BIM and LC in a megaproject dominated by the owner. The interactional relations among the owner, BIM, and LC were analyzed and positive interactions were identified. These positive interactions served as a basis for the implementation of this integrated approach in a case study and could be applied to other megaprojects. The megaproject (i.e., airport construction project) was examined to verify the performance of the developed method. Results showed that the integration of BIM and LC dominated by the owner can improve management performance and achieve high quality standard.

《工程管理前沿(英文)》 2019年 第6卷 第4期   页码 564-574 doi: 10.1007/s42524-019-0067-7

摘要: This study focuses on the influence of Chief Executive Officer (CEO) characteristics on environmental information disclosure (EID) in the annual reports of companies listed on the Stock Exchange of Thailand. A regression analysis method is used to explore the relationship between CEO characteristics and corporate environmental disclosure. Pollution-intensive companies are taken as the samples in this study. Results show that financial expertise, educational level, and tenure of CEOs are positively correlated with corporate EID. By contrast, age or gender of CEOs is insignificantly related to EID.

摘要:

Although numerous advances have been made in information technology in the past decades, there is still a lack of progress in information systems dynamics (ISD), owing to the lack of a mathematical foundation needed to describe information and the lack of an analytical framework to evaluate information systems. The value of ISD lies in its ability to guide the design, development, application, and evaluation of large-scale information system-of-systems (SoSs), just as mechanical dynamics theories guide mechanical systems engineering. This paper reports on a breakthrough in these fundamental challenges by proposing a framework for information space, improving a mathematical theory for information measurement, and proposing a dynamic configuration model for information systems. In this way, it establishes a basic theoretical framework for ISD. The proposed theoretical methodologies have been successfully applied and verified in the Smart Court SoSs Engineering Project of China and have achieved significant improvements in the quality and efficiency of Chinese court informatization. The proposed ISD provides an innovative paradigm for the analysis, design, development, and evaluation of large-scale complex information systems, such as electronic government and smart cities.

Building information modeling and its impact on users in the lifeworld: A mediation perspective

《工程管理前沿(英文)》 2019年 第6卷 第2期   页码 193-206 doi: 10.1007/s42524-019-0013-8

摘要: Building information modeling (BIM) is expected to have a large impact on users in the lifeworlds in a construction supply chain. The impact of BIM on users in their lifeworlds is explored using the concepts of Heidegger, Habermas, and Ihde from the perspective of technical mediation. This impact is explored by a case study. BIM mediates and shapes the relationship between users and their lifeworlds and can be characterized as either a hermeneutic or an alterity relationship. BIM conflicts with existing work practices in a ready-to-hand work environment. For users that cannot work with BIM, the work environment remains present-at-hand. The many heterogeneous BIM applications and systems used by the various parties involved result in interoperability problems that are a major barrier to enframing the supply chain by BIM. Although invitation and inhibition of certain actions by BIM may stimulate the rationalization of the lifeworlds, the lack of intrinsic motivation and mutual background knowledge inhibits an alignment of BIM and working practices.

《机械工程前沿(英文)》 2017年 第12卷 第3期   页码 357-366 doi: 10.1007/s11465-017-0423-4

摘要:

Given the weak early degradation characteristic information during early fault evolution in gearbox of wind turbine generator, traditional singular value decomposition (SVD)-based denoising may result in loss of useful information. A weak characteristic information extraction based on µ-SVD and local mean decomposition (LMD) is developed to address this problem. The basic principle of the method is as follows: Determine the denoising order based on cumulative contribution rate, perform signal reconstruction, extract and subject the noisy part of signal to LMD and µ-SVD denoising, and obtain denoised signal through superposition. Experimental results show that this method can significantly weaken signal noise, effectively extract the weak characteristic information of early fault, and facilitate the early fault warning and dynamic predictive maintenance.

摘要: With the development of information technology in the past 12 years, China has established the specialized or vertical web-based information systems for data collection of disease and related risk factor. These information systems are described as public health information systems (PHIS) in China. When PHIS has thus evolved in a haphazard and fragmented way under the pressure administrative, economic and legal, local health workers who are overburdened with multiple and time-consuming reporting requirements cannot deliver timely, accurate and complete data. Seeing that the information of disease surveillance is provided by hospitals and health service centers in China and that the development of electronic medical record (EMR) and electronic health record (EHR) occurs under the policy and investment of health since 2009 in China, there should be a connection and data sharing mechanism between EMR (EHR) and PHIS to support public health surveillance and public health decision-making. The paper aims at discussing current status and problems of PHIS in China, making a brief introduction on the blueprint of health information technology in China, exploring solution for interoperability between PHIS and EHR (EMR), and sharing some experiences and lessons from pilot project on automatic notifiable infectious disease reporting.

《工程管理前沿(英文)》 2020年 第7卷 第1期   页码 47-62 doi: 10.1007/s42524-019-0089-1

摘要: Against the background of addressing global climate change and carbon emission reduction, corporate carbon information disclosure (CID) has become an important measure to achieve carbon emission reduction worldwide and a research hotspot closely investigated by the academia. This study provides a systematic overview of literature on CID, including its research trend, theoretical basis, disclosing features, influencing factors, and consequences. Results indicate that, first, CID has been increasing in recent years, but the content and quality of the disclosure still need to be improved. Second, the main influencing factors of CID include company features, corporate governance, environmental performance, institutional characteristics, and stakeholders. Third, the consequences of CID are based mainly on company performance, ecological environment, and investors’ decision-making. Lastly, most studies have confirmed the positive effect of CID on company performance and investors’ decision-making, but the nexus of environmental performance and corporate CID remains to be investigated. Several important future research directions are also proposed based on these results.
