Advanced RAMS* modeling
& Reliability Data Management
K-DELIS Reliability Engineering (or simply K-DELIS) is a consulting company composed of Reliability Experts specialized in probabilistic modeling for Safety and Dependability analyses of industrial systems.
* RAMS = Reliability, Availability, Maintainability, Safety
Our core belief
“At K-DELIS, we strongly think that there is far more value to unlock from RAMS models and Reliability data than what the market currently offers.”
Nicolas CLAVÉ, Reliability Expert, CEO|Founder of K-DELIS
This guiding principle is rooted in more than 20 years of experience in dependability modeling, analysis, and calculations, as well as in reliability data management, structuring and analysis. It is reinforced by over a hundred RAMS studies conducted or led across both industrial and R&D projects.
Our approach
Build RAMS models and collect/structure reliability data in order to:
- Streamline asset design, whether in operation or development, while meeting Reliability/Availability/Production Availability targets
- Cut costs through smarter technical and operational choices
- Benchmark equipment performance to guide better decisions
- Reduce CO₂ emissions with optimized configurations
- Refine operating philosophies, maintenance strategies and spare parts management
Key questions and challenges K‑DELIS helps you to address:
Could you save costs by reducuing the redundancy level of your power generation system without compromising safety and performance?
Could your historical data justify extending test intervals and cutting operating costs while keeping safety intact?
How will connecting your plant to another installation (electric power cable) influence your performance?
Do your solar and battery capacities truly meet your availability targets?
Which system architecture delivers the optimal balance between performance, safety, cost, and emissions?
How could you build a structured reliability database starting from the different tools you already have on site?
How could you compare your different load shedding policy options from performance point of view?
Can you refine your testing policies and maintenance strategies using the reliability data collected on site?
Is your design genuinely fit‑for‑purpose in real operating conditions?
Taking into account all planned and unplanned maintenance interventions to achieve, do you have the right level of capital spares?
Would revisiting our supplier contracts help shorten procurement times and boost performance?
Will this new unit, or the upgrade of an existing one, impact your asset’s performance?
Service offerings include…
- Comprehensive RAMS studies: Reliability assessment of safety systems including Safety Integrity Levels (SIL) of Safety Instrumented Systems (SIS, HIPS), as well as conventional Reliability, Availability, Maintainability analysis and Dependability/Production Availability studies;
- Reliability data management: Field feedback data collection support, quality assurance, quality control processes and data analyses;

- Training: Delivering training sessions on reliability/availability assessment methodologies and modelling tools, as well as data management.
“RAMS modeling has long been a cornerstone across industrial sectors, driving smarter, safer, and more efficient systems. Today, with exponential gains in computing power and the rise of data-driven strategies, models have evolved, becoming richer, sharper, and more predictive than ever. This leap empowers us to deliver actionable insights for decision-makers to boost both performance and safety while cutting costs with efficiency.”
