    ATLAS is a specification language defined to outline city sections as cell spaces. A static view of the city section to be analyzed can be defined and a modeler is able to define complex traffic models in a simple fashion. A compiler for this specification language (called TSC) was built. The language implements the ATLAS constructions as Cell-DEVS models. The rule generation for describing the tr...

    An intermodal rail terminal is a facility where the transfer of cargo occurs between truck and rail. The operations within these terminals involve many resources and operating rules. The ability of a terminal to respond to activity peaks that occur as a result of train arrivals and departures is critical. In order to explore how operations can be improved given the dynamics of resource and demand ... View full abstract»

    Hybrid agent-based simulation is required to provide a mechanism for analyzing large-scale complex systems, such as the National Airspace System (NAS). The dynamic behavior of many complex systems is, in general, hybrid in nature and can be best described by a combination of discrete-event and continuous-time models, and their interactions. Correspondingly, hybrid agent-based simulation capable of... View full abstract»

    A large class of problems of sequential decision-making can be modeled as Markov or semi-Markov decision problems, which can be solved by classical methods of dynamic programming. However, the computational complexity of classical MDP algorithms, such as value iteration and policy iteration, is prohibitive and will grow intractably with problem size. Furthermore, they require for each action the o... View full abstract»

    Air traffic delay is a growing and expensive problem. We investigated ways to reduce the cost and magnitude of such delays by trading gate delays against more expensive air delays. Air management and planning at this level can be facilitated by simulation, especially for strategies that alter controls on the system. We used the SIMMOD air traffic simulation to model the system. The objective was t... View full abstract»
