Lean techniques impact evaluation methodology based on a co-simulation framework for manufacturing systems

Lean implementation plays a major role in optimizing productivity and reducing waste. Applying the adequate integration of Lean Techniques (LT) can ensure a higher profitable benefit. Many companies face difficulties in choosing the LT that best suit their situations to reach their objectives. In this study, we propose the simulation of specific modeled industrial contexts and check the impact of implementing LT simultaneously. Market fluctuation, demand diversification, and uncertainty of resources contexts are studied to perceive how LT behaves accordingly. Four KPIs (Key Performance Indicators) are retained for the analysis: Work in Progress, Lead-time, Production Throughput, and Defect Rate. An aeronautical company is modeled and experiments are performed to demonstrate the usefulness of a developed co-simulation framework to perceive the sensitivity of LT to some industrial contexts. The results showed that Poka Yoke and 5S are context-free LT valid in any industrial context. Pull, SMED, and Cross training are contextual and deserve careful applicability regarding the simulated context. Cross training, suitable for uncertainty of resources, does not show any significant improvements when the company was exposed to market fluctuations and demand diversification contexts

Business models for distributed-simulation orchestration and risk management

Nowadays, industries are implementing heterogeneous systems from different domains, backgrounds, and operating systems. Manufacturing systems are becoming more and more complex, which forces engineers to manage the complexity in several aspects. Technical complexities bring interoperability, risk management, and hazards issues that must be taken into consideration, from the business model design to the technical implementation. To solve the complexities and the incompatibilities between heterogeneous components, several distributed and cosimulation standards and tools can be used for data exchange and interconnection. High-level architecture (HLA) and functional mockup interface (FMI) are the main international standards used for distributed and cosimulation. HLA is mainly used in academic and defense domains while FMI is mostly used in industry. In this article, we propose an HLA/FMI implementation with a connection to an external business process-modeling tool called Papyrus. Papyrus is configured as a master federate that orchestrates the subsimulations based on the above standards. The developed framework is integrated with external heterogeneous components through an FMI interface. This framework is developed with the aim of bringing interoperability to a system used in a power generation compan

The use of the IEEE HLA standard to tackle interoperability issues between heterogeneous components

Classical simulation methods become not flexible and performant enough in complex models, necessitating the use of a distributed simulation technique to split the load and heterogeneity into separate sub-components and manage the simulation time between them. In this type of simulation, interoperability and reusability issues arise and should be addressed. The IEEE High-Level Architecture (HLA) standard for distributed simulation emphasizes federates interoperability and reusability, as well as time management and advanced data distribution techniques. This paper presents the methodologies and techniques used to develop the HLA federates, as part of the Simulation Exploration Experience (SEE) project, to virtually recreate a mission on the moon. This project is organized by the National Aeronautics and Space Administration (NASA) and the Simulation Interoperability Standards Organization (SISO). For each SEE component, an HLA interface was developed to make it compliant with other SEE federates and reusable during the simulation run. Based on HLA mechanisms, heterogeneous components with an HLA interface were able to interexchange objects/attributes and interactions/parameters

A Multicomponent Distributed Framework for Smart Production System Modeling and Simulation

In order to control manufacturing systems, managers need risk and performance evaluation methods and simulation tools. However, these simulation techniques must evolve towards being multiperformance, multiactor, and multisimulation tools, and this requires interoperability between those distributed components. This paper presents an integrated platform that brings interoperability to several simulation components. This work expands the process modeling tool Papyrus to allow it to communicate with external components through both distributed simulation and cosimulation standards. The distributed modeling and simulation framework (DMSF) platform takes its environment into consideration in order to evaluate the sustainability of the system while integrating external heterogeneous components. For instance, a DMSF connection with external IoT devices has been implemented. Moreover, the orchestration of different smart manufacturing components and services is achieved through configurable business models. As a result, an automotive industry case study has successfully been tested to demonstrate the sustainability of smart supply chains and manufacturing factories, allowing better connectivity with their real environments

Contribution à une Méthodologie et un Environnement de Co-Simulation pour évaluer l’impact du Lean sur la Performance de l’Entreprise

Aside from the human and managerial skills necessary to propel any business, the right Lean deployment can play a big role in reducing waste and maximizing efficiency. Capturing these benefits is highly dependent on adequate Lean techniques integration. One of the major hurdles companies face is the difficulty to choose the Lean tools that best fit their contexts and that are best tailored towards reaching their objectives. In this study, we proposed an HLA based Co-Simulation framework with a Java-based digital platform to allow different federates (discrete event simulations), representing the operational Lean tools, running simultaneously in parallel. Time management mechanisms of HLA are required for regulating the advancement of the federates during the simulation run. An example of an Aeronautic company is used to demonstrate the usefulness of this co-simulation framework. Six Lean configuration models are investigated under market fluctuation, demand diversification, and uncertainty of resources contexts compared with an actual model simulated as a Lean free scenario.Au-delà des compétences humaines et managériales nécessaires pour développer une entreprise, le bon déploiement du Lean peut jouer un rôle important dans la réduction des gaspillages et la maximisation de l'efficacité. Ces avantages dépendent fortement de l'intégration adéquate des techniques Lean. L'un des principaux obstacles auxquels font face les entreprises est la difficulté de choisir les outils Lean qui correspondent le mieux à leurs contextes et qui sont les mieux adaptés à l’atteinte de leurs objectifs.Dans cette étude, nous avons proposé un environnement de co-simulation basé sur HLA avec une plateforme digitale basée sur Java pour permettre à différents fédérés (simulations à évènements discrets) qui représentent les outils opérationnels Lean de fonctionner simultanément en parallèle. Les mécanismes de gestion du temps de HLA sont nécessaires pour réguler l’avancement des fédérés pendant le cycle de simulation. Un exemple d’entreprise aéronautique est utilisé pour démontrer l’utilité de cet environnement de co-simulation. Six modèles de configuration Lean sont étudiés par rapport au modèle actuel de l’entreprise simulé sans l’application du Lean, et ce sous l’influence de la fluctuation du marché, de la diversification de la demande et de l’incertitude des ressources

Couplage de FMI et HLA pour lngénierie de Systèmes

International audienceModeling and Simulation (M&S) are important steps in design process. Increasing the complexity of engineered system tend to raise Distributed Simulation (DS). Papyrus, an open source UML/SysML modeler of the Eclipse foundation provides a tool to model and simulate these two languages thanks to the fUML standard. However, Papyrus is not yet able to deal with DS. In this paper, we propose a DS composed of several Papyrus instances. Each made of an UML Profile, a Moka extension, and software architecture. The main objective is to synchronize the execution of these Papyrus instances. We are using Functional Mockup Interface (FMI) to enable communication between them. Nevertheless, the FMI standard does not natively include time management. Indeed, we propose to use the High-Level Architecture (HLA) standard to manage time between Papyrus simulations with FMI communication.
