Storingsrisiko

Storingsrisiko is a concept used in risk management and reliability engineering to describe the probability that a disturbance or fault will occur in a system and the potential consequences of that disturbance. In practice, it combines the likelihood of an incident with the severity of its outcomes, such that risk can be represented as R = P × C, though many frameworks use matrices or multi-criteria scoring rather than a single numeric product.

Disturbances may arise from equipment failures, process deviations, human error, external events, or a combination thereof. The specific meaning and acceptable levels of storingsrisiko depend on context, including the criticality of the system, the safety implications, and the costs of downtime or harm.

Assessment of storingsrisiko typically proceeds with qualitative methods (FMEA, fault tree analysis, HAZOP) to identify failure modes and causes, and with quantitative approaches (probabilistic risk assessment, reliability-centered maintenance, Monte Carlo simulations) to estimate probability and consequence distributions. In power systems or critical infrastructure, storingsrisiko is linked to reliability indices and contingency analyses.

Mitigation focuses on reducing either the probability or the impact of disturbances. Common measures include design for reliability and redundancy, preventive and predictive maintenance, monitoring and diagnostics, automatic protection and isolation, robust operating procedures, and staff training. Incident response planning and contingency arrangements further limit the consequences when disturbances occur.

Storingsrisiko is used across industries, including manufacturing, energy, transport, and IT, and is closely related to concepts such as resilience and safety risk. It supports prioritization of risks and allocation of resources for preventive and corrective actions.
