02- Availability Tracking and Metrics

  • Rossano Giachino (CERN)

Description

Availability is the amount of time a system is working at its full functionality during the time it is required to do so. The key metrics involved in measuring availability are Mean Time Between Failure (MTBF), sometimes referred to as Mean Time to Failure (MTTF), and Mean Time to Repair (MTTR). The methods for tracking availability and setting performance metrics can be different for each laboratory or institute. They are typically measures of success that can allow for facility performance over time and comparisons between facilities. How are they developed for your facility? How do subsystem metrics influence the overall metrics? The values and methods used by different labs should be shown and explained.

    Availability Tracking and Metrics
    Talk

    There are a lot of storage ring light sources operational, and
    users, funding agencies and others compare these light sources.
    If different light sources are compared, one important
    parameter is the beam availability. A meaningfull comparison of
    availabilities is only possible if the numbers are calculated
    the same way.

    At ARW 2013 in Melbourne a group of operations managers began to...

  2. 72. Creation, Tracking, and Reporting of Reliability Statistics at the APS

    Availability Tracking and Metrics
    Talk

    The Advanced Photon Source is a third generation light source that consistently provides beam reliability above 98% with MTBF in excess of 90 hours. This presentation will show how we use automated tools to acquire and interpret reliability data and how that data is used to prepare reports on machine reliability.

  3. 93. CERN's approach to availibility tracking and metrics

    Availability Tracking and Metrics
    Talk

    The consideration of availability tracking and availability metrics at CERN differs significantly between different parts of the organisation. Equipment experts are predominantly concerned by equipment failure rate and repair time. Operators are concerned by the amount of time which is lost due to faults. Physicists are concerned by the amount of physics which is lost due to faults.
