Abstract: A method, an apparatus and a computer program product predict the behavior of entities. They include identifying a plurality of parameters for the behavior of a plurality of entities, narrowing the plurality of entities to a plurality of entities of interest based on a scenario, predicting the behavior of the entities of interest within the elected scenario, and calibrating the predicted behavior of entities to an observed behavior for the entities of interest. The entities of interest are persons with luggage.

Abstract: The invention relates to a method for the computer-assisted analysis of the reliability of a technical system comprising a plurality of technical components. According to the method, the reliabilities of the components are respectively described by a component function that depends on at least one parameter and a parameter interval of the at least one parameter, which is associated with the components and influences the reliability of the components; a system reliability of the technical system is determined from the reliabilities of the components; a variation value is respectively determined for at least some of the components f&, constituting a value for the variation of the system reliability according to the variation of the parameter interval of the respective component; and an influence quantity relating to the influence of the respective components on the system reliability is respectively determined for at least some of the components from the variation value.

Abstract: A method for simulating object flows which move in an area, the method being based on cellular automata is improved in such a way that the simulation depicts the object flows as realistically as possible. It is further proposed that based on a desired speed of an object, the speed is lowered as the object density increases using a brake class table having a plurality of brake classes in such a way that a relationship between the object density and the object speed results according to a fundamental diagram. Thus, conventional methods for simulation of object flows are improved. The method is suitable in particular for flows of persons.

Abstract: A method and apparatus for the simulation of object streams moving in an area based on cellular state machines can be improved such that the simulation maps the object streams as realistically as possible. It is also being proposed that the norm of a difference vector having direction of movement of an object and the direction of movement of a neighboring object is also incorporated as a weighting factor in a calculation of the object potential. Thus, conventional methods for the simulation of object streams are improved. The method and apparatus is particularly suitable for streams of people.

Abstract: In a method and an apparatus for identifying, measuring and assessing anomalies in the behaviour of streams of people or objects, anomalies are identified, measured and assessed reliably and in all of their possible forms. At least one group in a stream of people or objects is statically identified at a particular time, the group is observed in a time profile, the group speed is measured and the streams of people or objects are assessed using the group speed. Various methods for detecting the group speed and various cases for assessing the group speed are shown. The method and apparatus is suitable for observing object streams in order to prevent accidents, for example.

Abstract: In a method for simultaneous observation and analysis of a plurality of data sets, in particular from webcams or sensors published over the Internet, atypical situations can be detected from a plurality of data sets of mostly low quality by producing metadata that are investigated for critical structures. Moreover, atypical situations can be recognized by comparing actual object mass properties of a data set with the target object mass properties of a data set. In this way, for example, human crowds or masses in pedestrian zones, football stadiums or subway stations can be effectively monitored and the large number of freely available internet cameras can be utilized.

Abstract: In a brake system for a train, which has a plurality of axles, at least one freewheeling axle is activated for determining the position of the train and the remaining axles are activated as non-freewheeling axles for braking the train. In the event of failure of a brake which is provided on a non-freewheeling axle, a previously freewheeling axle is activated as a non-freewheeling axle and the non-freewheeling axle which has a failed brake is activated as a freewheeling axle for determining the position of the train.

Abstract: A technical system is broken down into a plurality of subsystems, each of which is allocated a time-dependent distribution function which describes the probability of failure of the respective subsystem. The distribution functions are linked to one another to form a time-dependent system distribution function which describes the probability of failure of the technical system.

Abstract: A method for modeling conveyance or flows of material or other functional behaviors, particularly in the form of components that generate material actions; a method for modeling a system having components, particularly a postal item distribution system, and; the generation of a discrete component-oriented simulation model based on the modelings, particularly as a basis for components and/or system implementation. Modeling of each component is carried out on the basis of a flexible component model that takes the input behavior and the functional behavior of a component into account, and that two components at a time transfer discrete events or discrete material units to one another by using a general communications model, particularly by using communication types.
