1. Device for assisting the monitoring and/or simulation of a complex system, in particular of a communication network, characterised in that it comprises:

  • a memory (ROM, RAM) for storing a first set of data representing parameters of the network as well as for receiving at least a second set of data representing events in the network, a portion of the memory being reserved for storing data in matrix form, a computing unit (CAL) capable of effecting on at least two matrices of dynamically variable structure an operation forming a product according to the algebra known as MAX-PLUS, a modelling unit (MOD) for constructing at least a first matrix (Z(n)) and a current matrix (A(n)) respectively according to the first set of data and second set of data according to a selected model, and a pilot unit (PIL) for applying iteratively the first matrix and the current matrix to the computing unit, the product matrix obtained (Z(n+1)) becoming a new first matrix.
