Information management | EPFL Graph Search

Information management (IM) is the appropriate and optimized capture, storage, retrieval, and use of information. It may be personal information management or organizational. IM for organizations concerns a cycle of organizational activity: the acquisition of information from one or more sources, the custodianship and the distribution of that information to those who need it, and its ultimate disposal through archiving or deletion. This cycle of information organisation involves a variety of stakeholders, including those who are responsible for assuring the quality, accessibility and utility of acquired information; those who are responsible for its safe storage and disposal; and those who need it for decision making. Stakeholders might have rights to originate, change, distribute or delete information according to organisational information management policies. Information management embraces all the generic concepts of management, including the planning, organizing, structuring, pr

A Digital Platform connecting Academia and Small Businesses: An opportunity for Knowledge Management Experiments

Quentin Adrien Cavillier

Digital transformation is one of the biggest phenomena of this decade. One enabler of this revolution was cloud computing. Today, software engineers can deliver software as a service (SaaS), which is accessible to users through the Internet. Slack, Shopify, and Dropbox are examples of successful SaaS. We are experiencing an emergence of numerous small web applications with easy-to-use features for specific domains such as project management, accounting, resources management, customer relationships, and so forth. Thus, SaaS has been recognised as particularly well suited for the digital journey of small enterprises. However, surveys conducted by governmental agencies reveal a low adoption rate of SaaS by small enterprises in traditional sectors such as construction, services, and dealership. Previous studies have highlighted a lack of top management support, a weak relative advantage perceived, and a lack of knowledge as the key reasons for this low level of adoption. Whilst academic research defines these critical factors, it has not found potential solutions to mitigate them. Thus, this thesis presents two exploratory studies to enhance the adoption of digital practices by small traditional enterprises (STEs). A first study explored the value of leading collaborative projects between students and STEs about the assessment of SaaS solutions. A secondary objective of this initiative was the design of a platform acting as an open innovation platform. A three-year study allowed the completion of thirty-nine projects and the testing of two different platform designs. The feedback from students demonstrated the value of a well-structured platform composed of different management models for each project phase. Furthermore, 67 per cent of the STEs involved on the platform acknowledged the value of such collaborative projects. However, the collaborations did not improve top management support, and projects tended to stagnate because of various organisational factors. A second study, using a mixed-methods research design, was performed to explore the relations amongst the organisational factors acting as enablers and barriers to the digitalisation of STEs. The objective was to improve understanding of TSEs' situation and devise a proposition to enhance top management support. An academic contribution of this study was the design and application of a conceptual framework combining organisational factors from the literature on dynamic capabilities, organisational inertia, and intellectual capital. The combination of the qualitative observations and quantitative results highlighted the importance of the sensing and leadership capabilities for STE directors. They also revealed the mediator effect of the relational capability on the development of these latter. Therefore, this thesis makes important contributions to the literature on open innovation by defining a new field for leading knowledge management experiments. It also contributes to develop a comprehensive overview of the organisational factors affecting STEs' adoption. A further major contribution is the potential value of the digital platform to innovate the services of practitioners, such as governmental agencies and consultants, that support STEs on their digital transformation journey. In conclusion, this research is valuable in opening the discussion about potential innovations that might reshape the relationship academia-business.

A blockchain and IoT-based lightweight framework for enabling information transparency in supply chain finance

Jingjing Chen, Jinzhi Lu

Supply Chain Finance (SCF) refers to the financial service in which banks rely on core enterprises to manage the capital flow and logistics of upstream and downstream enterprises. SCF adopts a self-testing and closed-loop credit model to control funds and risks. The key factor in a successful SCF service is the deployment of SCF businessoriented information systems that allow businesses to form partnerships efficiently and expedite cash flows throughout the supply chain. Blockchain Technology (BCT), featuring decentralization, tamper-proofing, traceability, which is usually paired with the Internet of Things (IoT) in real-world contexts, has been widely adopted in the field of finance and is perfectly positioned to facilitate innovative collaborations among participants in supply chain networks. In this paper, we propose a BCT and IoT-based information management framework (named BC4Regu), which works as the regulatory to improve the information transparency in the business process of SCF. With BC4Regu, the operation cost of the whole supply chain can be significantly reduced through the coordination and integration of capital flow, information flow, logistics and trade flow in the supply chain. The contributions in this paper include: (1) proposing a novel information management framework which leverages Blockchain and IoT to solve the problem of information asymmetry in the trade of SCF; (2) proposing the technical design of BC4Regu, including the Blockchain infrastructure, distributed ledger-based integrated data flow service, and reshaped SCF process; and (3) applying BC4Regu to a group of scenarios and conducting theoretical analysis by introducing the principal-agent model to validate the BC4Regu.

Addressing the need to monitor concrete fatigue with Non Destructive Testing: results of Infrastar European project

Antoine Bassil, Imane Bayane, Eugen Brühwiler, Xiao Wang

Fatigue is one of the most prevalent issues, which directly influences the service life expectancy of concrete structures. Fatigue has been investigated for years for steel structures. However, recent findings suggest that concrete structures may also be significantly subjected to fatigue phenomena that could lead to premature failure of certain structural elements. To date, fatigue of reinforced concrete has been given little focus. Knowledge on the influence factors and durability/capacity effects on this material should be improved. Current technological means to measure fatigue in civil structures like bridges and wind turbines (both onshore and offshore) are outdated, imprecise and inappropriate. Meanwhile, this topic has got much more attention as time-variant loading on concrete structures plays an increasing role, e.g. in bridges with increasing traffic and heavier trucks, and for wind turbines for renewable energy production, e.g. for offshore wind turbine support structures affected by wind and waves. The European Innovative Training Networks (ITN) Marie Skłodowska-Curie Actions project INFRASTAR (Innovation and Networking for Fatigue and Reliability Analysis of Structures - Training for Assessment of Risk) provides research training for 12 PhD students. The project aims to improve knowledge for optimizing the design of new structures as well as for more realistic verification of structural safety and more accurate prediction of the remaining fatigue lifetime of existing concrete structures. First, the INFRASTAR research framework is detailed. Then it will be exemplified through the presentation of the major results of the four PhD students involved in the work package dealing with auscultation and monitoring. This includes the development and improvement of Fiber Optics (FO) and Coda Wave Interferometry (CWI) for crack sizing and imagery, new sensor technologies and integration, information management, monitoring strategy for fatigue damage investigation and lifetime prediction.
