Emergent technologies for inter-enterprises collaboration and business evaluation

International audienceConventional manufacturing systems are designed for intra-enterprise process management, and they hardly handle processes with tasks using extra-enterprise boundaries data. Besides, inter-enterprise collaboration and new IT enablers for industry 4.0 are becoming a highly topical issue to study, due to : (a) The emergence of new technologies mainly Internet of Things, big data processing and Cyber-Physical systems (b) The new customers' needs that face the SMEs. Many constraints and issues have to be taken into account before establishing Inter-enterprises collaboration, namely: The product information, the business processes and the heterogeneous data. Moreover, the exponential growth of data coming from all the enterprises causes several challenges regarding their exploitation. In this context, this study is interested in Big Data capabilities to help Small and Medium Enterprises to find out more lurking opportunities. We have focus on the combination between emergent IT technologies, mainly Big Data, and inter-interprises collaboration in order to provide an added value. The result of this study is a new approach, that could be adapted by SMEs, for new project evaluation within a network of enterprises

An Agile development method for platoon system based on Verification and Validation

International audienceThis paper introduces a verification and validation (V&V) process in a product life-cycle, where we consider a V&V process as the composition of the three tasks: formal verification, simulation and experimentation. The considered application is a platoon system, a set of autonomous vehicles that move together without any material connection. The platoon system development considers the specification of the SafePlatoon project(1). Main goal of the V&V process is to put to the proof the platoon controller (Decision making unit). V&V is then a corner stone for critical functions that require zero default. Algorithm and hardware must respect some security concerns such as collision free between platoon vehicles, platoon integrity, obstacles avoidance, and etc. After a specification phase, where safety properties are defined, a classical or agile V&V cycle can be applied. In the case of SafePlatoon project, where different partners are evolving simultaneously on the models, an agile development method is used; where formal verification and benchmark simulation works together in order to improve model's safety. Formal verification is made using The SAL model checker. Validation by simulation is made using an internal tool called Vivus

Vips: a Simulator for Platoon System Evaluation

International audienceDevelopment of intelligent behaviors for vehicles has to cope with rigorous specifications. Many tests are performed for verification, validation and a detailed study of resulting behaviors. In this workflow, testing algorithms with real vehicles is a cornerstone step in developing new intelligent features for future transportation systems. This step requires a lot of experiments before efficiently set up embedded autonomous systems. However, the development of such tests is not linear and it highly depends on external variable factors (weather, hardware or software issues, etc.). To overcome these issues, it is possible to carry out a first series of validation under a simulation framework. In this paper, we describe a simulation platform called VIPS (Vehicles In Platoon Simulator), which provides a virtual environment designed to test and validate platoon control approaches, as close as possible to reality, before bringing them in the real vehicle system. Among the features provided by the simulator, one main contribution is the direct matching between perception and control of both real and virtual vehicles. Moreover, VIPS is also able to deal with perturbations, which are dynamically added to running scenarios so as to reproduce real world conditions. Simulation results in the context of platoon control systems show the benefits of the proposed simulation framework

Using Physics Inspired Wave Agents in a Virtual Environment: Longitudinal Distance Control in Robots Platoon

International audienceThe monitoring and the surveillance of industrial and agricultural sites have become first order tasks mainly for security or the safety reasons. The main issues of this activity is tied to the size of the sites and to their accessibility. Thus, it seems nowadays relevant to tackle with this problem with robots, which can detect potential issues with a low operational cost. To that purpose, in addition to individual patrolling behavior, robots need coordination schemes. The goal of this paper is to explore the possibility of using interference fringes and waves properties in a virtual environment to tackle with the longitudinal distance regulation in the platoon control issue. The proposed model, based on a multi-agent paradigm, is considering each vehicle as an agent wave generator in the virtual environment

WAVE: Wave Agents in a Virtual Environment; a Proof of Concept Applied to Longitudinal Distance Regulation in Platoon Control

International audienceSince a decade multi-agents became a widespread solution to tackle different kinds of issues in various application fields. Among the two main trends in multi-agent approaches (cognitive vs. reactive), the reactive one is particularly interesting for applications that require both fast response time, adaptability and robustness. Reactive Multi-agent Systems rely on simple interaction schemes between entities that can be inspired whether by Biology or Physics. The goal of this paper is to explore the possibility of using interference fringes and waves properties from a multi-agent standpoint so as to tackle a real problem, longitudinal platoon regulation, already explored by different strategies including particle agents approaches or standard PID controller

The challenges, approaches, and used techniques of CPS for manufacturing in Industry 4.0: a literature review

International audienceThis work aims to review literature related to the latest cyber-physical systems (CPS) for manufacturing in the revolutionary Industry 4.0 for a comprehensive understanding of the challenges, approaches, and used techniques in this domain. Different published studies on CPS for manufacturing in Industry 4.0 paradigms through 2010 to 2019 were searched and summarized. We, then, analyzed the studies at a different granularity level inspecting the title, abstract, and full text to include in the prospective study list. Out of 626 primarily extracted relevant articles, we scrutinized 78 articles as the prospective studies on CPS for manufacturing in Industry 4.0. First, we analyzed the articles’ context to identify the major components along with their associated fine-grained constituents of Industry 4.0. Then, we reviewed different studies through a number of synthesized matrices to narrate the challenges, approaches, and used techniques as the key-enablers of the CPS for manufacturing in Industry 4.0. Although the key technologies of Industry 4.0 are the CPS, Internet of Things (IoT), and Internet of Services (IoS), the human component (HC), cyber component (CC), physical component (PC), and their HC-CC, CC-PC, and HC-PC interfaces need to be standardized to achieve the success of Industry 4.0

A Cyber-Physical model for platoon system

International audienceCyber-Physical system (CPS) are now widely used in the design of smart objects. A CPS is the integration of computational elements with physical processes. One of the most widespread application of CPS is the autonomous transportation systems. This paper presents a CPS model for the design of a platoon system approach (i.e. a set of autonomous vehicles that move together without any mechanical link while maintaining a predefined configuration). The proposed approach to platoon issue can be considered to be decentralized since each vehicle perceives its environment and acts based only on its own perceptions. The proposed approach deals with different platoon formation. The vehicles of the platoon are able to maintain their position in the configuration while avoiding collision with obstacles. The paper shows some simulation and experimentation results that allow to evaluate the quality of the proposed platoon approach
