​System Reliability and Availability

Anchor 1

Reliability is a staple in most businesses. It is the probability that a component, part, system, or process performs correctly within a specified period. A reliable system is one that will function appropriately with a minimum need for maintenance or repair

Most systems in facilities constitute interconnected components, with each component playing its role and helping to achieve a performance level. A system reliability assessment allows businesses to identify weaknesses of these components and quantify the impact of their failures on the overall system or process.

ORS is a leading system reliability solutions provider. We are helping businesses and facilities with a wide range of services, including uptime and availability assessments, Fault Tree Modelling, among others.

​System Reliability and Availability Related Studies


FMEA (Failure Modes and Effect Analysis) and FMECA (Failure Modes Effects and Critical Analysis) are methodologies used to determine potential failure modes in a system and provide corrective measures for each failure mode. FMECA is similar to FMEA with regard to risk assessment and failure analysis. However, in addition to FMEA functionalities, FMECA ranks failure modes in order of severity.

RAM Analysis

RAM analysis is a method to define the production capacity and availability of a system to keep producing. This analysis involves a mapping of the different failure modes, frequencies, consequences, and their effect on production. RAM Analysis helps to reduce costs, debottleneck and provide input to spare parts and maintenance planning. Learn more >

Production Assurance

Production assurance describes the certainty of a facility achieving its production goals and meeting its intended end-results. End results may be customer expectations, the safety of a production process, or reduced production costs. Production assurance is particularly important within systems associated with oil and gas exploration and is introduced in ISO 20815:2008 standard.

Fault Tree Modeling  

Fault Tree Modeling is a methodology used for conducting reliability analyses of complex systems. It involves creating a logical representation to model chains or pathways that can lead to failure or an undesirable loss event. It helps to keep systems safe and in desirable operating conditions.

System Safety 

System safety is a risk management methodology that involves the identification and analysis of different hazards in a system, process, or facility. It also involves the provision of measures to eliminate or mitigate the effect of these risks. Among others, system safety is widely applied in the defence industry.
