A unified failure/damage approach to battle damage regeneration : application to ground military systems. In- Abstract: Availability is a determining factor in systems characterization. Because they must act in a hostile environment, military systems are particularly vulnerable in situations of non-availability. Military weapon systems availability can be affected by system failures or by damage to the system, and in either case, system regeneration is needed. However, very few availability studies take battlefield damage into account in their more general dependability studies. This paper takes a look at the issues and trends related to the study of battlefield damage, specifically those related to the modeling of such damage and it proposes a unified approach to regeneration engineering that exploits the parallelism between failure and damage in order to manage system failure and damage to the system.

Dynamic model for assessing impact of regeneration actions on system availability: Application to weapon systems

“…The proposed modeling approach is presented in Figure 1 [4]. The global method is based upon 3 modeling steps.…”

“…To deal with this problem, we previously proposed a unified multi-step failure/damage modeling approach [4], developed in partnership with NEXTER Group, a French weapons systems manufacturer, who must guarantee a certain level of regenerability in all the systems they sell (e.g., Leclerc Main Battle Tanks or the VBCI, a wheeled armored infantry fighting vehicle). According to the System Engineering process, the regenerability potential of new systems must be assessed in the design phase during dependability studies, but tools and methods are still needed for both the modeling and evaluation processes.…”

A Methodology for Weapon System Availability Assessment, Incorporating Failure, Damage and Regeneration

“…The proposed modeling approach is presented in figure 1, (Monnin et al, 2006). The dynamic model is based on a dependability model created using state-space methods.…”

“…The first 2 aspects have been already explained in detail in a previous paper (Monnin et al, 2006); the present paper focuses on the third aspect, the dynamic model, which uses simulations based on Stochastic Activity Networks (SAN) modeling. The rest of this paper is structured as follows.…”

“…Research considering both failure and damage is scarce, and as Campbell and Starbuck have mentioned (Campbell and Starbuck, 2005), there are currently no modeling and/or simulation methods that allow the impact of regeneration actions to be assessed dynamically. To deal with this problem, we previously proposed a unified multi-step failure/damage modeling approach (Monnin et al, 2006), developed in partnership with NEXTER Group, a French weapons systems manufacturer, who must guarantee a certain level of regenerability in all the systems they sell (e.g., Leclerc Main Battle Tanks or the VBCI, a wheeled armored infantry fighting vehicle). According to the System Engineering process, the regenerability potential of new systems must be assessed in the design phase during dependability studies, but tools and methods are still needed for both the modeling and evaluation processes.…”
