Methods of imitation modelling
for network tasks


"Mimoza-network" - is software product, aimed to solve probability tasks on networks by Monte-Carlo methods. It can calculate the reliability of technical systems under the construction, that the system can be described by a graph. A graph (maybe, multigraph) consists of nodes and links, no matter unidirectional or not. Every element (link) is described by the only parameter - the real number between 0 and 1. It may mean the probability of element`s default in a certain period of time. The parameters of all elements are independent. The criteria of servicability of system is any monotone indicate function of parameters. The following functions may service as such a criteria: presense of route between a certain pair of nodes, presense of routes from every nodes to a certain node, streight connectivity (presense of routes between every pair of nodes).
There are three methods of imitation modelling, that implemented in product. They append each other and allows to calculate a system of large size (up to a few thousand elements), of super-high reliability (up to 1e-300) and of high level nonisotropicness. There are: Implemented methods based on the concept idea "modelling till default" supposed by prof. Ushakov I.A.
Interface of programm allows to observe the computational process, change of system`s reliability estimate, its quadratic deviation. Also it allows to change operatively the options of work to make the date more obvisious and calculations more effective.
