Introduction to Reliability Principles

Stock Image. Furthermore, when reliability is not under control, then many and different sorts of issues may arise, for example:. The problem of unreliability may also become out of control due to the "domino effect" of maintenance induced failures after repairs and more and more increasing efforts of problem solving, re-engineering and service efforts.

Only focusing on maintainability is therefore not enough!


Reliability needs to be evaluated and improved related to both availability and the cost of ownership due to cost of spare parts, maintenance man-hours, transport costs, storage cost, part obsolete risks etc. Often a trade-off is needed between the two. There might be a maximum ratio between availability and cost of ownership. Testability of a system should also be addressed in the availability plan as this is the link between reliability and maintainability.

The maintenance strategy can influence the reliability of a system e. So, Maintainability and Maintenance strategies influences the availability of a system. In theory this can be almost unlimited if one would be able to always repair any fault in an infinitely short time. This is in practice impossible.

Repair-ability is always limited due to testability, manpower and logistic considerations. For high levels of system availability e. Refer to reliability engineering. An availability plan should clearly provide a strategy for availability control. Whether only Availability or also Cost of Ownership is more important depends on the use of the system.

For example, a system that is a critical link in a production system — e.

Availability - Wikipedia

A proper reliability plan should always address RAMT analysis in its total context. The simplest representation of availability is a ratio of the expected value of the uptime of a system to the aggregate of the expected values of up and down time, or. Average availability must be defined on an interval of the real line.

Limiting or steady-state availability is represented by [1]. Availability is the probability that an item will be in an operable and committable state at the start of a mission when the mission is called for at a random time, and is generally defined as uptime divided by total time uptime plus downtime. Fault tree analysis and related software are developed to calculate analytic or by simulation availability of a system or a functional failure condition within a system including many factors like:. Furthermore, these methods are capable to identify the most critical items and failure modes or events that impact availability.

Radio Frequency Identification RFID A wireless system that uses electromagnetic fields to automatically identify and track tags containing electronically stored information that are attached to objects.

RASCI chart Responsible, accountable, supported, consulted and informed chart that is used to summarise the roles and functions performed in a process and the activities within it. Real estate Encompasses land along with anything affixed to the land, such as buildings. Reactive maintenance Unplanned maintenance activities; an inevitable supplement to planned preventative maintenance regimes in the operation of a building.

Recycling The collection and processing of used materials in order to utilise the raw material to produce new products. Reliability Centred Maintenance RCM Systems-based methodology used to determine maintenance tasks necessary to ensure that a facility asset or system continues to function in order to fulfil its purpose as designed in its present operating context. Remedial work Redesign and work necessary to restore the integrity of building fabric and components to a standard that will allow the facility to perform its original function.

Residual life Period during which a material or component might reasonably be expected to continue to fulfil its present function provided it is routinely maintained. Restricted procedure Usually applies to high-value public sector contracts. Strict pre-qualification criteria are set for the contract, and only those suppliers meeting the criteria will be invited to tender. Risk assessments A systematic method of looking at work activities, considering what could go wrong and deciding on suitable control measures to prevent loss, damage or injury in the workplace.
