Model-Based Safety Assessment approach: Increase trust in models
Organizer
MILCENT Frédéric, frederic.milcent @ naval-group.com | Naval Group
Description
Model-Based Safety Assessment (MBSA) exists since many years now and the advantages of this approach are well known. However, modelers are sometimes confronted with the same old questions: Is the model really valid? Are the results correct? Those questions often take their origins in a lack of knowledge of the MBSA approach but reveal an important issue: how to prove the validity of models and results?
The following topics will be addressed:
- Modeling process
- Training & Communication
- Model representativeness
- Model-Checking
- Tools & Software
- Documentation & Capitalization
Motivation
The aim of this panel session is to give leads to modelers to prove the validity of their models. An example of modeling process will be proposed. Based on this process, few solutions will be presented:
- Plan MBSA to define inputs needed, objectives and development specification
- Model-Based System Engineering (MBSE) / MBSA coupling initiatives (S2C, S2ML…) and others methods to ensure the model representativeness to the corresponding system
- Model-checking for the verification of the consistency of the model
- Validation activities (step-by-step simulation…)
- Provide documentation with model for explanation
- MBSA supporting activities (training & communication) and resources (database, existing patterns…)
- Possibilities offered by MBSA tools & languages to assist modelers

Abstract
RAM (Reliability-Availability-Maintainability) Engineering is by now a mature discipline, tracing its roots back to the immediate post-World War II period.It deals with statistical properties of a population of assets, characterizestheir failure modes and aims at optimizing the design of future equipment based on past experience, analysis and tests. It takes into account maintenance and operations context and also provides inputs to the elaboration of maintenance plans and logistic support.RAM analysis at the design stage is typicallymodel-based(while exploiting past data), andRAM Monitoring is data-driven but may be supported by models.PHM (Prognostics & Health Management)emerged at the turn of the 21stcentury. It deals typically with individual assets which are equipped withsensors and aims at monitoring their health and its progressivedegradation,so as to diagnose impending failures, and to avoid them by taking preventive actions when possible. Three main pillars of PHM are detection, diagnostics and prognostics.
PHM relies on model-based, data-driven or hybrid approaches.Typically the two communities are separate for historical reasons.The question we would like to raise here is: can the two communities both benefit from stronger links?For example, the first stage in developing a PHM system is a failure mode, mechanisms and effects analysis(FMMEA), which is typically a RAM task. And one key expected outcome from a PHM strategy is increased availability.While RAM focuses on estimating the probability distribution of the lifetime of a population, in a givenenvironmentwith an average mission profile, PHM, on the other hand, focuses on predicting the rate of function loss for an individual asset, with a customized profile and context. RAM deals with discrete events (failures), and metrics such as failure rate and MTTF or MRL (mean residual life); while PHM deals with continuous, degradation data, and metrics such as health indicators (or indices) and RUL (remaining useful life). While RAM leads to maintenance decisions (such as spares management and determination of maintenance intervals)for a whole fleet, PHM supports maintenance decisions for one individual asset.The ‘M’(maintainability) in RAM includestestability, which addresses the ability todetect and diagnosefaults—an essential concern for PHM.The IoT paves the way for individualized monitoring. Both RAM and PHM can be supported by machine learning techniques along with classical statistics. Therefore the borders between the two disciplines may be getting blurred.Can cross-fertilization occur in both directions ? For instance, can PHM not draw on the considerable body of knowledge accumulated by RAM specialistsover decades (including the venerable theories of the ‘founding fathers’, such as Barlow & Proschan, or Gnedenko, which PHM engineers often are not familiar with).And at the same time, cannotRAM Engineering be rejuvenated by machine learning algorithms and perspectives (which often RAM Engineers do not necessarily have in their toolbox)?Should corporate RAMS departments give way to RAM/PHM departments?And what are the implications for higher education and research ?

Description
This special session will be organized in the format of a panel for discussing autonomous systems safety, risk, and security (SRS). The session will discuss the results of the First International Workshop on Autonomous Systems Safety (IWASS), as well as early findingsof the 2ndIWASS. Key experts will be invited to discuss autonomous systems SRS from an interdisciplinary and cross-industrialperspective. The panelis expected to present the results from IWASSdiscussions and make them more accessible to a wider audience. Participants may present additional thoughts on the discussions and workshop outcomes.Motivation
The First IWASS was organized by the Department of Marine Technology at the Norwegian University of Science and Technology (NTNU) and the B. John Garrick Institute for the Risk Sciences at the University of California, Los Angeles (UCLA). IWASS took place in Trondheim, Norway, from March 11thto 13th,2019. The 47 participants were selected and individuallyinvitedto the workshoponly and included 47. Thesubject matter experts came from Europe, Asia, Australia, and the U.S.A., working in both academia and industry.The 2ndIWASS is planned as a virtual event to be held in April 2021.Autonomous systems on land, in the air and on the sea are being widely applied. Thesafety issues concerning these systems are the focus of many research projects and publications, yet each industry and academic field attempts to solve arising safety issues on their own. Given theidentifiable similarities, could common solutions be envisioned and developed? Answering these and related questions motivatesthis panelas an opportunityfor an interdisciplinary discussion on risks, challenges, and foremost potential solutions concerning safe autonomous systems and operations.
