    Modeling and simulation through the metamodeling perspective : the case of the discrete event system specification
    (Springer Cham, 2023-01-24) Blas, María Julia; Gonnet, Silvio
    The Discrete Event System Specification (DEVS) is a modeling formalism that supports a general methodology for describing discrete event systems with the capability to represent both continuous and discrete systems due to its system theoretic basis. This chapter addresses the use of metamodeling and the role of related technologies in the Modeling and Simulation (M&S) field, mainly devoted to implementing DEVS models. The main aim is to answer the following questions: What is the significance of model-based engineering in the M&S field? Can a computational representation of DEVS defined following the principles of metamodeling improve the modeling task? How can DEVS models obtained through metamodeling integrate with simulators? This chapter discusses using metamodels as the foundation to define formal DEVS models from a computational point of view. A metamodel-based computational representation of DEVS formalism is described. From such a computational representation, how current technologies can be used to support DEVS metamodel in existing M&S software tools is discussed. The chapter shows how concrete DEVS models are used in existing M&S software tools to get executable simulation models through metamodel instantiation. Illustrative examples show how the DEVS metamodel improves the simulation model specification. The chapter concludes with a discussion of the current state of the metamodeling approach used in the M&S field and the remaining problems that need to be addressed in the future.

    Diseño e implementación de una herramienta de software para el modelado y simulación en RDEVS (WIP)
    (CoNaIISI, 2020) Blas, Maria Julia; Dalmasso, Fidel; Toniolo, Mateo; Gonnet, Silvio
    En los últimos años, el campo de Modelado y Simulación ha comenzado a abordar nuevas propuestas basadas en la construcción de modelos conceptuales como soporte al diseño e implementación de modelos de simulación. Bajo esta perspectiva, la definición de un modelo de simulación puede formularse partiendo de un modelo conceptual en el cual se abstrae el dominio del problema bajo estudio. En este trabajo se presenta la arquitectura de una herramienta de software para la construcción, ejecución y visualización de modelos de simulación basados en Routed DEVS. El formalismo Routed DEVS ha sido presentado con anterioridad como una subclase del formalismo Discrete Event System Specification que busca dar solución a la identificación de eventos como funcionalidad embebida dentro de los modelos de simulación. Se presenta un conjunto de módulos de software que toman como punto de partida una representación gráfica del dominio y generan el código Java asociado a los modelos requeridos. Estos módulos son acompañados de módulos de captura de datos y visualización de información con el objetivo de proveer al usuario, de forma simple y amigable, una evaluación del estado resultante de cada corrida de simulación.

    Developing RDEVS simulation models from textual specifications
    (CBSoft 2022 - IV Workshop on Software-Intensive Systems Modeling and Simulation (MSSiS), 2022) Espertino, Clarisa; Blas, Maria Julia; Gonnet, Silvio
    The Routed DEVS (RDEVS) formalism provides a formalization for routing process simulation. This paper presents the mapping between constrained network models obtained from textual specifications of routing processes and RDEVS simulation models implemented in Java. The proposal is part of a work-in-progress intended to develop M&S software tools for the RDEVS formalism using well-known abstractions to get the computational models attached to such abstraction models through conceptual mapping. Then, modelers can have simulation models without needing to codify any routing implementation. Benefits are i) reduction of implementation times and ii) simulation model correctness regarding the RDEVS formalism.

    Modeling routing processes through network theory : a grammar to define RDEVS simulation models
    (III Workshop on Software-Intensive Systems Modeling and Simulation (MSSiS), 2021) Blas, Maria Julia; Espertino, Clarisa; Gonnet, Silvio
    The Routed DEVS (RDEVS) formalism provides a reasonable formalization for the simulation of routing processes. In this paper, we introduce a context-free grammar for the definition of routing processes as a particular case of a constrained network model. Such grammar is based on a metamodel that defines the semantics over the syntactical elements. This metamodel allows a direct mapping between its concepts and RDEVS simulation models. A Java implementation is provided for the grammar as a plug-in for Eclipse IDE. The main benefit of this software tool is the feasibility of getting a simulation model without having programming skills
