Real-time data exploitation supported by model- and event-driven architecture to enhance situation awareness, application to crisis management

Abstract

An effective crisis response requires up-to-date information. The crisis cell must reach for new, external, data sources. However, new data lead to new issues: their volume, veracity, variety or velocity cannot be managed by humans only, especially under high stress and time pressure. This paper proposes (i) a framework to enhance situation awareness while managing the 5Vs of Big Data, (ii) general principles to be followed and (iii) a new architecture implementing the proposed framework. The latter merges event-driven and model-driven architectures. It has been tested on a realistic flood scenario set up by official French services.

An AI framework and a metamodel for collaborative situations: Application to crisis management contexts

“…With such claims, the evaluation of the proposed metamodel relies mainly on its genericity and adaptability to adapt to any problem linked to how networks collaborate. In practice, this is showed by the variety of applications is has already went through: automated virtual breeding environment (Montarnal et al, 2018), crisis management situational awareness (Fertier et al, 2019), crisis management resource planning (Bidoux et al, 2019), risk management (Clement, Kamissoko, Marmier, & Gourc, 2018). In most of the latter research, The current orientation of AI is mainly based on learning principles that exploit massive data to infer various types of outputs: classification of data, visualization of data, detection of patterns and signals, etc.…”

“…Besides, it is important to notice that the model of Figure 11 has been obtained fully automatically for the objective and context parts, as detailed in Fertier et al. (2019).…”

“…These considerations have been largely discussed in (Benaben et al, 2016) and are generally represented on the framework of Basically, the question of the use of data science for data interpretation and the design of situation model has been described (Fertier, Montarnal, & Benaben, 2019), as well as the question of information exploitation and model transformation to get a response model (Bidoux, Pignon, & Benaben, 2019;Montarnal et al, 2018;Mu, Benaben, & Pingaud, 2018). As a consequence, the following of this article will strongly focus on the "missing piece" of that puzzle: the metamodel.…”

Increasing the organizational performance of online sellers: the powerful back-end management systems

“…The core function of an e-commerce platform is to strengthen transactions and maintain the relationship between buyers and online sellers. Online sellers with strategic agility often sense opportunities for competitive action in their target markets and prepare themselves with the necessary knowledge and skills to exploit these opportunities (Sreejesh et al, 2022;Kohtamaki et al, 2020;Fertier et al, 2020), which is an essential capability for online sellers. In response to a constantly changing marketplace, these back-end management systems increase organizational performance, so online sellers can thrive in a virtual environment and maximize the benefits of e-commerce technology, such as through related applications or other innovative initiatives.…”
