The present modeling tool and method dynamically generate a maintenance simulation of a vehicle. For doing so, a configuration interface receives a list of components of the vehicle, each particular component comprising parameters defining the particular component. The configuration interface further receives relationships between the components in the list, and determines a plurality of state, transitions, conditions, triggers and actions. A processing unit processes the data received and determined via the configuration interface to generate the maintenance simulation, the maintenance simulation comprising an aggregation of all the determined transitions between the components into a global state machine. The present method may further be performed by a computer program product.
