Data architecture and model design for Industry 4.0 Components integration in Cyber-Physical Production Systems
In the context of Industry 4.0, Cyber-Physical Production Systems (CPPS) and digital twins are key technologies for the management of huge amount of data generated by Industrial Internet of things (IIoT) devices. However, the interoperability and flexibility of different components is still an important challenge so as to integrate them in the process and fit […]

Load testing and simulation of asymmetric cablenet used for flexible rockfall protection barriers
Flexible protection barriers are often located on the mountainsides in order to decrease the risk of rockfall. In the present study, different scales of experimental tests are considered, to gauge the behaviour and to estimate the bearing capacity of a new type of cable-nets used for these flexible barriers in case of quasi-static loads. A […]

VR simulation of operating procedure in construction based on BIM and safety ontology: a proof of concept
Virtual Reality has shown its relevance to assist in various construction activities. However, its use requires a lot of additional work to be integrated into BIM pro-cess. In literature, the usefulness of phasing BIM element for creating training session in AR or VR has been highlighted. Operating site procedures involve dif-ferent stakeholders such as QHSE […]

Multi-Agent Simulation for Flexible Job-Shop Scheduling ProblemWith Traffic-Aware Routing
This paper addresses the Flexible Job Shop Scheduling Problem (FJSSP) with transportation tasks between processing machines ensured by Automated Guided Vehicles (AGVs). It aims to study the effect of two operational constraints, usually neglected in literature, namely the traffic interactions between AGVs and loading/unloading operations. A multi-agent simulator is developed to simulate and analyse the […]

Generation and verification of learned stochastic automata using k -NN and statistical model checking
Deriving an accurate behavior model from historical data of a black box for verification and feature forecasting is seen by industry as a challenging issue especially for a large featured dataset. This paper focuses on an alternative approach where stochastic automata can be learned from time-series observations captured from a set of deployed sensors. The […]

An IoT-based Framework for an Optimal Monitoring andControl of Cyber-Physical Systems: Application on BiogasProduction System
Among the possible conversion processes for biomass is AnaerobicDigestion (AD) that produces a valuable energy known as biogas.However, the instability of biogas production is challenging dueto the complex process of the AD that requires a precise environ-mental conditions as well as different bacteria populations. Hence,monitoring and controlling these conditions and tracking the bac-teria behaviour inside […]

Authoring-By-Doing: An Event-Based Interaction Module for Virtual Reality Scenario Authoring Framework
Virtual reality (VR) and augmented reality (AR) have already shown their advantages in industrial use during these last years. Nevertheless, the authoring and editing process of virtual and augmented contents are still time-consuming and even more for complex industrial scenarios. Therefore, it is important to simplify the authoring process. For this purpose, we are working […]
