Quantifying Reliability. Maximising Performance.

In today’s competitive industrial environment, downtime is expensive, redundancy is costly, and over-design wastes capital.

xSeriCon’s RAM (Reliability, Availability, Maintainability) studies provide a structured, data-driven approach to quantify system performance before issues occur.

We help organizations design smarter, operate more efficiently, and invest with confidence.

What is a RAM Study?


RAM (Reliability, Availability, Maintainability) Study is a detailed simulation of a process over its operating lifetime. It provides a prediction of the percentage availability (uptime) of the process, considering factors such as the process architecture, input and output variability, maintenance and operational philosophy, utility failure, and equipment failure rate.

Typically, a “base case” is analysed, consisting of a normal set of operating conditions. Variations are then introduced to study the impact of changes on the process availability.

Why should you apply RAM study?

Before RAM Study
After RAM Study

Before RAM Study:
Decisions based on assumptions.

After RAM Study:
Decisions supported by quantitative reliability analysis.

Before RAM Study

AspectBefore RAM Study
System UnderstandingLimited understanding of system reliability and bottlenecks
Design DecisionsDesign based on assumptions or conservative estimates
Production PerformanceUnexpected downtime and production losses
Maintenance PlanningReactive or experience-based maintenance
Investment DecisionsDifficult to justify redundancy or equipment upgrades
Operational RiskHigher risk of system failures affecting operations
Cost EfficiencyHigher lifecycle costs due to unplanned downtime
Confidence in DesignUncertainty about whether the system will meet targets

After RAM Study

AspectAfter RAM Study
System UnderstandingClear insight into system reliability, critical equipment, and failure impacts
Design DecisionsDesign supported by quantitative reliability modelling
Production PerformanceImproved uptime and predictable production performance
Maintenance PlanningOptimized maintenance strategies based on reliability data
Investment DecisionsData-driven decisions for redundancy, spares, and system improvements
Operational RiskReduced operational risk through identified weak points
Cost EfficiencyLower lifecycle cost through optimized design and maintenance
Confidence in DesignVerified system availability and reliability performance
The main objectives
  1. Evaluating the production uptime of the process
  2. Identifying areas of weakness which contribute the greatest to production downtime
  3. Identifying the criticality of all equipment in the facility
  4. Analyse the impact of proposed changes to the base case by performing sensitivity analyses
  5. Identify underlying causes of recurrent failures
The major benefits of performing a RAM study
  1. Optimise capital expenditure on redundant/spare equipment
  2. Optimise maintenance philosophy, including scheduling, manning and spares inventory
  3. Provide defensible predictions of system reliability, for use in budgeting and safety case
  4. Identify optimal equipment usage in facilities handling more than one process or feedstock
  5. Plan for failure scenarios
RAM Study develops a model defining the interdependence of resources, equipment and manpower, depicting this in a "Reliability Block Diagram (RBD)". This is used to simulate plant performance, providing a range of insights including:

  1. Quantified System Availability

  2. Bottleneck Identification

  3. Redundancy Evaluation

  4. Maintenance Optimisation

  5. Spare Parts Planning

  6. CAPEX & OPEX Decision Support

Almost every industries that has a processing system could benefit from a RAM study

  1. Energy

  2. Petrochemical

  3. Manufacturing

  4. Transportation

  5. Food Production

  6. Pharmaceutical

  7. Semiconductor

  8. Many more…

Beyond Safety — Real Business Impact
