Approche unifiée défaillance-dommage dans la sûreté de fonctionnement pour la régénération des matériels au combat : application aux systèmes d'armes terrestres

Abstract : The French Procurement Agency (DGA) aims at defining the needs of French Army and actually works to define the BOA (airland operational bubble). In this particular operational context military systems have to integrate regeneration facilities defined has system’s ability to return damaged or disabled component to temporary service in order to fulfil its mission. Nexter group which designs and manufactures armoured vehicles to meet the needs of Army has to guarantee the operational availability of the systems they sell. Thus, operational availability assessment has to integrate failure damage and regeneration in the same modelling process. Although failure are considered in dependability framework and damage are studied in the survivability framework, taking into account regeneration remains difficult due to the lack of modelling methods and tools that incorporate failure damage and regeneration in a unified way. In that way, our contribution is related to a modelling method based on system engineering that allows defining a generic modelling atom for the system behaviour representation. A dynamic model based on the modelling atoms aggregation has been developed by means of Stochastic Activity Networks that allow simulations to be completed for the availability assessment. The feasibility and the added value of the approach are experimented on a system architecture jointly defined by the DGA and Nexter Group.
