Operational Availability (Ao) Sample Clauses

Operational Availability (Ao). Ao is availability during all segments of time when the equipment is intended to be operational. Ao provides the most realistic measure of availability of equipment deployed and functioning in a combat environment. However, one significant problem associated with determining Ao is the calculation of ALDT and PMT. Defining ALDT and PMT under combat conditions is not feasible in most instances and data collected during a test may not provide a good estimate. Either the discrete model (for on-demand equipment) or the continuous model of operational availability may be used, as appropriate. Discrete Model. Ao = Number of Times the System is Available Number of Times the System is Required Continuous Model. Ao = UpT UpT + DnT = OT + ST OT + ST + TCM + TPM + TALDT Where: OT = The operating time during OMS/MP ST = Standby time (not operating, but assumed operable) during OMS/MP TCM = The total corrective maintenance downtime in clock hours during OMS/MP TPM = The total preventive maintenance downtime in clock hours during OMS/MP TALDT = Total administrative and logistics downtime (caused by OMFs) spent waiting for parts, maintenance personnel, or transportation during OMS/MP. (Note that events attributed to downtime may consist of Operational Mission Failures and Essential Maintenance Actions; and, are system specific dependent on that system’s formally defined Failure Definition/Scoring Criteria.)

Operational Availability (Ao). The probability that an item will be mission capable when it is required. Xx is defined mathematically as the ratio between uptime and total time. It is the quantitative link between readiness objectives and supportability. (DAU Glossary) For on- demand systems, it can also be defined as the ratio of ready systems to the number of available systems. See the various Service appendices to this annex for Service-specific Ao formulas.
Operational Availability (Ao). The degree (expressed as a decimal between 0 and 1, or the percentage equivalent) to which one can expect a piece of equipment or weapon system to work properly when it is required. Operational Availability is calculated by dividing uptime by the sum of uptime and downtime. It is the quantitative link between readiness objectives and supportability. (DAU Glossary) It can also be calculated by the number of systems that are ready, divided by the number possessed (e.g., the number of times the system was available, divided by the number of times the system was required) for on-demand systems. See the various Service appendices to this annex for Service specific Ao formulas.

  • General Availability The commitment to availability specified in the letter of appointment shall be subject to mutually acceptable revision. Such revision will occur once per year, or, if mutually agreed between the Employer and the employee, on a more frequent basis. The Employer will issue a revised letter of appointment to reflect approved changes to employee’s general availability.

  • Service Availability You understand that Service availability is at all times conditioned upon the corresponding operation and availability of the communication systems used in communicating your instructions and requests to the Credit Union. We will not be liable or have any responsibility of any kind for any loss or damage thereby incurred by you in the event of any failure or interruption of such communication systems or services resulting from the act or omission of any third party, or from any other cause not reasonably within the control of the Credit Union.

  • EPP service availability Refers to the ability of the TLD EPP servers as a group, to respond to commands from the Registry accredited Registrars, who already have credentials to the servers. The response shall include appropriate data from the Registry System. An EPP command with “EPP command RTT” 5 times higher than the corresponding SLR will be considered as unanswered. If 51% or more of the EPP testing probes see the EPP service as unavailable during a given time, the EPP service will be considered unavailable.

  • High Availability Registry Operator will conduct its operations using network and geographically diverse, redundant servers (including network-­‐level redundancy, end-­‐node level redundancy and the implementation of a load balancing scheme where applicable) to ensure continued operation in the case of technical failure (widespread or local), or an extraordinary occurrence or circumstance beyond the control of the Registry Operator. Registry Operator’s emergency operations department shall be available at all times to respond to extraordinary occurrences.

  • System Availability System Availability percentage is calculated as follows:  Total MinutesintheMonth −Downtime   System Availability%age =  Total MinutesintheMonth *100    System Availability SLA (“SLA”) 99.5% System Availability percentage during each Month for productive versions Credit 2% of Monthly Subscription Fees for each 1% below SLA, not to exceed 100% of Monthly Subscription Fees Excluded Downtime Total Minutes in the Month attributable to: (i) a Scheduled Downtime for which a Regular Maintenance Window is described in Section 4 below, or (ii) any other Scheduled Downtime according to Section 4 for which the customer has been notified at least five (5) business days prior to such Scheduled Downtime or (iii) unavailability caused by factors outside of SAP’s reasonable control, such as unpredictable and unforeseeable events that could not have been avoided even if reasonable care had been exercised. Scheduled Downtime Scheduled Downtime for the applicable Cloud Services to which customer has subscribed is set forth in Section 4 below entitled “Maintenance Windows for Cloud Services”.
