A conceptual modeling framework for discrete event simulation using hierarchical control structures

Abstract

Conceptual Modeling (CM) is a fundamental step in a simulation project. Nevertheless, it is only recently that structured approaches towards the definition and formulation of conceptual models have gained importance in the Discrete Event Simulation (DES) community. As a consequence, frameworks and guidelines for applying CM to DES have emerged and discussion of CM for DES is increasing. However, both the organization of model-components and the identification of behavior and system control from standard CM approaches have shortcomings that limit CM’s applicability to DES. Therefore, we discuss the different aspects of previous CM frameworks and identify their limitations. Further, we present the Hierarchical Control Conceptual Modeling framework that pays more attention to the identification of a models’ system behavior, control policies and dispatching routines and their structured representation within a conceptual model. The framework guides the user step-by-step through the modeling process and is illustrated by a worked example.

“…Adicionalmente, permite crear un archivo digital, comúnmente utilizado para el diseño de las operaciones de sistemas de fabricación incluidas las operaciones de planificación y programación en tiempo real. La SD se ha empleado, entre otras, para la industria de productos agrícolas, químicos, alimentos, automotriz, cuidado de la salud y construcción (Furian et al, 2015;Golzarpoor et al, 2017;Kouki et al, 2017;Negahban y Smith, 2014;Rodríguez, et al 2018). Por su parte la Modelación de Sistemas Dinámicos (MSD), es una herramienta de construcción de modelos de simulación, que combina estructura, función y enfoque histórico de un proceso, donde además se almacenan experiencias, para explicar la naturaleza del comportamiento de un sistema.…”

A Conceptual Framework to Classify the Extensions of Devs Formalism as Variants and Subclasses

“…Then, its main purpose is to elicit the conceptual schema of a specific system (Olivé 2007). Several authors have used these types of models in order to illustrate different simulation approaches (Yilmaz and Oren 2004;Robinson 2006;Furian et al 2015;Robinson et al 2015;Abdelmegid et al 2017). All these approaches deal with the conceptual modeling field as a problem related to the modeling phase when building a simulation model.…”
