“…In the process oriented DEVS formalism, "systems are described from the point of view of the entities that flow through them using the available resources" (Sanz, Urquia, and Dormido 2009). For assembly line models this means that it is possible to track and identify each manufactured item during its flow through the line.…”

“…To support modelling activities, some of these programs also integrate sophisticated 3D visualisation. There is also a Modelica library which can model discrete event simulation, since it adopts the Discrete EVents System (DEVS) formalism (Sanz, Urquia, and Dormido 2009;Sanz, Urquia, Cellier, et al 2012;DESLib 2023). It offers a rich but complex functionality.…”

The Modelica language is well suited to model systems with discrete and continuous dynamics. If one wants to model the flow of items through manufacturing steps such as preparation, mounting, or transport in the shop floor, this feature is crucial. The library ProcessSimulation can be used to model such processes. By default, it omits the technical details of the process steps, and focuses on the flow of material items through the process steps. In addition to that, a base model to calculate the energy consumption in the different manufacturing steps is provided. It can be enriched with technical details of the components. The library can be used for the calculation of (net) energy consumption, but also for task planning.

The benefits of integrating the Parallel DEVS (P-DEVS) formalism with the Equation-Based Object-Oriented modeling languages (EOOL), which constitute the state-of-theart for continuous-time system modeling, are discussed. The characteristics of the Equation-Based Object-Oriented (EOO) methodology are presented. The requirements to describe P-DEVS models using an EOOL are evaluated. These requirements are detailed for the case of the P-DEVS formalism and the Modelica language, with the introduction of the DEVSLib Modelica library. DEVSLib facilitates the description of P-DEVS models in Modelica, and allows the combination of DEVS models together with other Modelica libraries in order to construct multi-formalism hybrid models. DEVSLib has been developed by the authors and is freely available at http://www.euclides.dia.uned.es.

Modelica is a general-purpose modeling language mainly designed to facilitate the development, reusability and exchange of models. It represents the state-of-the-art in equation-based modeling of continuous-time systems. Modelica libraries facilitate the description of multi-formalism and multi-domain models. However, the description of agent-based models (ABMs) in Modelica is not currently supported, mainly due to the characteristics of the language and its simulation algorithm. The combination of ABMs with continuous-time equations provides a powerful tool for describing and analyzing complex systems. An approach for describing ABMs using the Modelica language is presented in this manuscript, with the objective of facilitating the combination of ABMs with the rest of Modelica functionality. Agent behavior is described using a process-oriented modeling approach. Agents are described as individual entities that move across a flowchart diagram, that represents the processes that agents undergo. Processes are formally described using the Parallel DEVS formalism, extended to describe the interface with other Modelica models. The environment where agents interact is described as a cellular automaton. This approach has been implemented in a free Modelica library, named ABMLib. Three case studies are discussed to illustrate the modeling functionality of the library and its combination with other models: a basic traffic model, a sheep–wolves predator–prey model and a consumer market model.
