Abstract: Recent advances in computer technology have influenced simulation techniques to become an effective approach to understand physical systems. In recent years, grid-shaped cellular models have gained popularity in this sense. In particular, Cellular Automata (CA) have been widely used with these purposes. Despite their usefulness to describe complex behavior, CA can require large amounts of compute time, mainly due to its synchronous nature. The use of a discrete time base also constrains the precision of the model. Besides this, CA do not describe adequately most of existing physical systems whose nature is asynchronous. The Cell-DEVS formalism was defined in order to attack these problems. The goal of Cell-DEVS is to build discrete-event cell spaces, improving their definition by making the timing specification more expressive. We will introduce the main characteristics of the Cell-DEVS formalism, and will show how to model complex cell spaces in. We will present different examples of application, and discuss open research issues in this area. We will then focus on advanced models of pedestrian flow and crowds. The methodology uses a cellular modeling approach in which each cell is defined as a discrete event agent, and defines a procedure to couple cells evolving the state of the influenced neighbors.
