Asset condition is a key parameter in determining remaining useful life, and can be used to predict how long it will be before an asset needs to be repaired, renewed or replaced. Asset condition is also an indicator of how well it is able to perform its function. Evaluating the status of asset life-cycle based on condition and reliability data, with a scientific approach and integrated data, will support your reliability program review, contributing to the reduction of the asset management.

With risk-based inspections, maintenance task analysis, and reliability-centered maintenance analysis, you can develop high-quality reliability strategies and programs that ensure your assets and asset investments deliver optimal value, maximize safety, and enhance regulatory compliance. With assetwise asset reliability you can: identify assets posing the greatest risk to your business and rank assets by failure consequence and relative risk.
Criticality analysis is the tool to use if you want to improve reliability and manage plant assets based on risk instead of perception. The asset criticality ranking is used to help prioritize maintenance work and to identify the most critical assets -- the top 10 or 20% -- for further analysis using simplified failure modes and effects analysis (sfmea).

In summary, the reliability index says that you want to operate as long as possible without losses; and when you have losses, you want to fix them as quickly as possible. What is asset management? asset management is another word hijacked by providers of maintenance services and products, especially by computer system suppliers.
The rpn approach calculates a value for each asset that is assessed. Ratings are assigned to three basic factors; severity of failure effect, likelihood of occurrence, and likelihood of detection before the failure reaches the customer.
Finally, detailed asset management for observed area is formed and combined with reliability analyses. Main goal is to show on a realistic network model how statistics of operational events.
A well-applied, managed fluid analysis program becomes a major tool in maintaining your equipment in tip-top condition. While it is an additional cost, fluid analysis can pay dividends in keeping the equipment running longer, minimizing repairs and decreasing downtime.

Our asset reliability services are focused on two drivers at the forefront of every sector where we do business: higher reliability and lower maintenance costs for all key assets.
Per military standard mil-std-721c, reliability is defined as “the duration or probability that an item can perform its intended function for a specified interval under stated conditions. ” the reliability of an asset is typically expressed in hours either by mean time between failures (mtbf) or by mean time to failure (mttf).
Average for type of asset; recurrent minor repair; close monitoring required; most senior people required to sustain performance maintenance is frequent with recurrent patterns of failure; asset must be virtually constantly monitored to sustain performance % physical life consumed almost new; up to 10% physical life consumed up to 30% physical life.

One type of enhanced asset management tool can be based on distribution network reliability analysis. Failure rate models used in traditional reliability analysis.
Determining the reliability required of an asset during the design phase the level of reliability of an asset, as determined by its fundamental design (and installation) is often termed its “inherent reliability” (see mil-hdbk-338b: electronic design reliability handbook).

The assets section provides following information for each piece of equipment belonging to a reliability distribution analysis: this family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges.
These are based on reliability engineering that improves the reliability of a system or complex equipment. Frequently, the industry implements maintenance schemes, which are based on equipment’s manufacturer’s recommendations and may not apply changes throughout the asset life cycle.
The inherent reliability required of the asset is generally used as the primary basis for design decisions. Inherent reliability (the level of reliability of an asset, as determined by its fundamental design and installation) differs from “operational reliability” which is the reliability of the asset actually observed in operation.
Understanding criticality and where it fits in your reliability engineering plans is, well, critical to the success of your asset management program. But there are some commonly held myths and misperceptions about criticality. These top myths and pitfalls often prevent organizations from performing a comprehensive criticality analysis.
The system automatically collects many types of data from different databases within an organization then performs filtering, basic statistical analysis, reliability.
Improving the reliability of physical assets takes far more than just monitoring their condition, improving lubrication practices, and making some improvements to the maintenance department. To have a truly successful program you must understand how to add value to the organization and thus gain senior management support.
The asset criticality ranking will reveal which assets have a high ranking due to poor reliability - they will be good targets for reliability improvement projects. It will reveal where assets have a high criticality due to lack of detectability - that is a good place to implement condition monitoring.
Robert ross's book gives a deep insight in useful statistical analysis methods for asset management practice. It covers all the basics and specific distributions in a structured and understandable way, before it sets out to give its insight into system and component reliability.
A reliability, availability and maintainability (ram) analysis typically starts from the creation of a diagram that represents the overall system/process and the corresponding major subsystems. The next step is to expand the major subsystems into subsubsystems and keep repeating until you reach the level where reliability information is available (ideally at the lru level).
