what is the difference between system reliability and system safety?

Reliability requirements are concerned with making a system failure-free. Definition: Safety Safety is the probability, that no catastrophic accidents will occur during system operation, over a specified period of time. Safety looks at the consequences and possible accidents.

The following are a few differences between risk and uncertainty: In risk you can predict the possibility of a future outcome, while in uncertainty you cannot. Risks can be managed while uncertainty is uncontrollable. Risks can be measured and quantified while uncertainty cannot.

Reliability refers to how consistent the results of a study are or the consistent results of a measuring test. ... For example, if a research study takes place, the results should be almost replicated if the study is replicated. Validity refers to whether the study or measuring test is measuring what is claims to measure.

Safety is often defined as the avoidance of injury and harm, while quality is typically defined as achieving the best possible health care outcomes.

Safe systems of work. A safe system of work (SSoW) is a formal procedure based on a systematic examination of work in order to identify the hazards. It defines safe methods of working which eliminate those hazards or minimise the risks associated with them.

Safety is the condition of being protected from harm or other non-desirable outcomes, caused by non-intentional failure. Security is the condition of being protected from harm or other non-desirable outcomes caused by intentional human actions or human behavior.

Safety stock provides a buffer of inventory for you to dip into when the above circumstances occur, while reorder point provides a buffer of time for you to restock on merchandise. This means fewer rush fees owed to suppliers, less operational chaos, and a more efficient use of warehouse space.

Difference Between Hazard and Risk (Infographic) ... A hazard is something that has the potential to cause harm while risk is the likelihood of harm taking place, based on exposure to that hazard.

Hardware damage can render any of the latest and greatest useless. Whether is was a clogged fan, spilled water, or dropping it on the floor. When that moment arises, you know that it could all be gone within a matter of seconds. System Failure is the complete malfunction of a computer system.

Mistake proofing focuses on both the prevention and detection of defects, while error proofing focuses solely on prevention. Error proofing breaks the chain of causality so that neither the faulty action nor the resulting defect can occur.

A safe system of work is a step-by-step method of carrying out a task that considers the hazards and risks involved and clearly states the control measures required. The site-specific risk assessment will determine whether a safe system of work is required. The safe system of work must be completed using the template.

Fault, Error and Failure. Fault : It is a condition that causes the software to fail to perform its required function. Error : Refers to difference between Actual Output and Expected output. Failure : It is the inability of a system or component to perform required function according to its specification.

Fundamentally, High Availability and Disaster Recovery are aimed at the same problem: keeping systems up and running in an operational state, with the main difference being that HA is intended to handle problems while a system is running while DR is intended to handle problems after a system fails.

Risk Management, as a discipline, teaches the process in a specific manner while Safety Management, as a discipline, is often more varied. But the processes are still essentially the same.

Performance: Performance refers to a product's primary operating characteristics. ... Reliability: Reliability is the likelihood that a product will not fail within a specific time period. This is a key element for users who need the product to work without fail.

While fail-safe products are unlocked when power is removed (i.e. power is applied to lock the door), fail-secure products are locked when power is removed (i.e. power is applied to unlock the door). Fail safe/fail secure refers to the status of the secure side (key side, outside) of the door.
