TL;DR: In this article, a method and apparatus for managing a simulation is presented, where information about the simulation is received over a wireless communications link with a computer system in an aircraft, and the information is received during running of the simulation and identifies a performance of the computer system running the simulation.
Abstract: A method and apparatus for managing a simulation. Information about the simulation is received over a wireless communications link with a computer system in an aircraft. The information is received during running of the simulation and identifies a performance of the computer system running the simulation. The running of the simulation is controlled based on the performance of the computer system.

TL;DR: A parallel traffic simulation approach is presented that is aimed at reducing the time for simulating emergency vehicular traffic scenarios by achieving absolute (as opposed to self- relative) speedup with a sequential speed equal to that of a fast, de facto standard sequential simulator for emergency traffic.
Abstract: Vehicular traffic simulations are useful in applications such as emergency management and homeland security planning tools. High speed of traffic simulations translates directly to speed of response and level of resilience in those applications. Here, a parallel traffic simulation approach is presented that is aimed at reducing the time for simulating emergency vehicular traffic scenarios. Three unique aspects of this effort are: (1) exploration of optimistic simulation applied to vehicular traffic simulation (2) addressing reverse computation challenges specific to optimistic vehicular traffic simulation (3) achieving absolute (as opposed to self- relative) speedup with a sequential speed equal to that of a fast, de facto standard sequential simulator for emergency traffic. The design and development of the parallel simulation system is presented, along with a performance study that demonstrates excellent sequential performance as well as parallel performance.

TL;DR: A procedure to build simulation models for move-store activities of complicated and non-automated distribution warehouses is proposed and the simulation model is designed to execute together with the program for generating parameters of materials handling.
Abstract: The distribution warehouse is located between manufacturers and customers Storage facilities are designed around four primary functions: holding, consolidation, break-bulk, and mixing In addition, materials handling within a storage-handling system reduces to three primary activities: loading and unloading, movement to and from storage, and order filling Generally, it is more difficult to build a simulation model for a non-automated warehouse than for AS/RS, because materials handling is much more complicated In this study, a procedure to build simulation models for move-store activities of complicated and non-automated distribution warehouses is proposed The simulation model here is designed to execute together with the program for generating parameters of materials handling Then, simulation analysis is performed, using a simulation model built by the proposed procedure

TL;DR: An attempt to forecast traffic flow from the viewpoint of non-linear time series based on the theory of phrase space reconstruction for traffic flow system and self-organizing Map (SOM) network is introduced to seek the near neighbor.
Abstract: Short-term traffic flow forecasting plays a very important role in urban traffic management and control. In this paper, According to the chaotic property of urban traffic flow, we compute the parameters of phrase space reconstruction for traffic flow system. Meanwhile, a local-forecasting method is introduced to predict urban road short-term traffic flow based on the theory of phrase space reconstruction. Self-organizing Map (SOM) network is introduced to seek the near neighbor. Case study using real traffic flow data from UTC-SCOOT system proves the validity of the method. The research in this paper is a significant attempt to forecast traffic flow from the viewpoint of non-linear time series.
