Abstract: A method for generating synthetic data records which include datasets that capture state-based transitions, according to which a state transition family is randomly selecting, according to the distribution of samples between the different clusters of users and the context variables are randomly sampled according to their distribution within the chosen cluster. The relevant Markov Chains models are selected according to the sampled context and the initial state of the sequence is randomly selected according to the distribution of states. A random walk process is initialized on the graph models and the random walk is performed process on each context separately, assuming context independency. The cause condition of the current transition is sampled for each state transition, based on the distributions on the selected edge.

Abstract: A user of a management system, with which the user's reachability is managed, is assigned a reachability matrix in the system. This reachability matrix stores, in the form of reachability records, the respective reachability of the user via the communications media available to him in relation to a plurality of possible statuses. When events occur that result in a change of status with respect to the statuses recorded in the user's matrix, a reachability record of the user's matrix is defined as the actual reachability vector for the respective user on the basis of rules stored in the system, which reachability vector contains information for each medium available to the user for communication as to whether the user is at the moment to be reachable via the respective communications medium. For each communications medium affected by the change, the management system may generate control signals.
