    An approach to agent-based modeling with Modelica
    (Elsevier, 2018-04) Bergero, Federico; Sanz Prat, Víctorino; Urquía Moraleda, Alfonso
    Modelica is a free, general-purpose object-oriented equation-based modeling language. It is mainly designed to describe systems using the physical modeling approach. Our proposal to describe Agent-Based Models (ABMs) in Modelica is discussed in this manuscript. The contribution of the presented work is twofold: firstly, to analyze the conceptual requirements to describe ABMs in Modelica; and secondly, to develop a prototype implementation following the previous analysis. Agents are described using a message passing communication mechanism previously proposed by the authors. Additional extensions to this mechanism are proposed in order to describe agent interactions. The environment, where the agents live, is described as a two-dimensional cellular automaton. A new Modelica library, named ABMLib, developed to support this functionality, is presented. A prototype implementation of the message passing mechanism and ABMLib models has been performed to demonstrate the functionality of the library as a proof-of-concept for this proposal. The library is freely available at www.euclides.dia.uned.es/vsanz.

    Extending Modelica Support for Parallel DEVS and Cellular Automata Modeling and Simulation
    (Nova Science Publishers, 2017-09) Sanz Prat, Víctorino; Urquía Moraleda, Alfonso
    Modelica is a general-purpose modeling language designed to describe mathematical models of physical systems using the object-oriented modeling approach. Since Modelica includes language constructs to manage discrete events, multiple discrete event modeling formalisms are supported, in the form of libraries of models. The authors have designed and developed the DEVSLib and CellularAutomataLib2 Modelica libraries to facilitate the description of Parallel DEVS (P-DEVS) and Cellular Automata (CA) models. P-DEVS can serve as underlying mathematical formalism to describe the discrete-event part of a hybrid model. The DEVSLib library has been used to develop the SIMANLib and ARENALib libraries that reproduce some functionality of the SIMAN language and the Arena simulation environment. On the other hand, the integration of CA models in Modelica is an interesting and promising topic. CA can be applied to the description of models that depend on the spatial coordinates and their simulation algorithm is conceptually simple. CellularAutomataLib2 facilitates the combination of CA models with the object-oriented modeling approach supported by Modelica. The design and functionality of these libraries and their integration with other Modelica models is discussed in this manuscript. Examples of a random delay P-DEVS model, a bank teller, a pendulum clock, an opto-electrical system, a tank level control system, a soaking-pit furnace and a SIR epidemic spread model are included to illustrate their functionality and use. These libraries are freely distributed at http://www.euclides.dia.uned.es.

    Simulation practice with Modelica
    (Universidad Nacional de Educación a Distancia (España). Editorial, 2018-10-01) Urquía Moraleda, Alfonso; Martín Villalba, Carla; Rubio González, Miguel Ángel; Sanz Prat, Víctorino
    This activity book is aimed to provide an introduction to the simulation practice in Engineering using Modelica. To this end, we propose a series of thirteen independent hands-on assignments of increasing complexity. Each assignment contains the description of a system and a mathematical model of the system's behavior. The proposed task often consists in describing this mathematical model in the Modelica language and simulate it. In some assignments, the system's behavior is described as an atomic model, without internal structure. Some other assignments ask to design and implement a model library, and to compose the system model by instantiating and connecting components from this model library. Before start working with this activity book, it is advisable to read its companion theory book: a free e-book entitled "Modeling and simulation in Engineering using Modelica", written by Alfonso Urquía and Carla Martín, and published by Editorial UNED in 2018
