In engineering, reliability, availability, maintainability and safety (RAMS) [1] [2] is used to characterize a product or system: Reliability: Ability to perform a specific function and may be given as design reliability or operational reliability; Availability: Ability to keep a functioning state in the given environment
A risk assessment is an important tool that should be incorporated in the process of identifying and determining the threats and vulnerabilities that could potentially impact resources and assets to help manage risk. Risk management is also a component of a risk control strategy because Nelson et al. (2015) state that "risk management involves ...
This term has been enshrined in the UK case law since the case of Edwards v. National Coal Board in 1949. The ruling was that the risk must be significant in relation to the sacrifice (in terms of money, time or trouble) required to avert it: risks must be averted unless there is a gross disproportion between the costs and benefits of doing so.

Example of risk assessment: A NASA model showing areas at high risk from impact for the International Space Station. Risk management is the identification, evaluation, and prioritization of risks, [1] followed by the minimization, monitoring, and control of the impact or probability of those risks occurring. [2]
Operational availability is a management concept that evaluates the following. [1] Diagnostic down time; Criticality; Fault isolation down time; Logistics delay down time; Corrective maintenance down time; Any failed item that is not corrected will induce operational failure. is used to evaluate that risk. Operational failure is unacceptable in ...
Risk management is predicting and managing risks that could hinder the organization from reliably achieving its objectives under uncertainty. Compliance refers to adhering with the mandated boundaries (laws and regulations) and voluntary boundaries (company's policies, procedures, etc.).
Assessed risk levels are used to develop a prioritized inspection plan. It is related to (or sometimes a part of) risk-based asset management, risk-based integrity management, and risk-based management. Generally, RBI is part of risk and reliability management. The basis of most RBI programs is the corrosion circuit, in which each circuit can ...
Reliability-centered maintenance (RCM) is a concept of maintenance planning to ensure that systems continue to do what their users require in their present operating context. [1] Successful implementation of RCM will lead to increase in cost effectiveness, reliability, machine uptime, and a greater understanding of the level of risk that the ...
