System Reliability. The reliability, at any point in time, of the System shall be determined by the System's operational capability for productive Department use as configured and installed within the specified operating environment. Continued acceptability of the reliability of the System’s performance shall be based on the Department’s experienced rate of recoverable and non-recoverable System operating errors or failures that preclude productive Department use of the System according to the requirements of this Contract and Contractor operating specifications. The required reliability (Computed % Reliability) for the System (exclusive of scheduled and routine maintenance) during any calendar month is ninety-nine point nine percent (99.9999%) uptime availability for aforesaid productive Department use, computed as follows: (Available-Time-per-Month) - (Downtime-per-Month) Computed % Reliability = ------------------------------------------------------------------- (Available-Time-per-Month) with Available-Time-per-Month equated to 24 hours times the number of days in the month, which shall be deemed to correspond to POP during each calendar month and Downtime-per-Month equated to those hours of Available-Time-per-Month during which the Department or any specific site is precluded from aforesaid productive System use. EXAMPLE: Given: Available-Time-per-Month was 720 hours. Downtime per-Month was 3.60 hours. (720 – 3.60) Then: Computed % Reliability = -------------------- = 99.5% 720 A given instance of System downtime shall start after receipt by the Contractor of a Department service request to remedy any operational System deviation, error, or failure condition(s), and end with documented proof, reasonably acceptable to the Department by Contractor to the Department that such System status has been fully restored to the applicable agreed operational specifications and made ready for productive Department use. However, the calculated time period of such an instance of System downtime shall exclude the following periods: Any nonproductive System use time caused by the Department or the Department's authorized third party and not related to a deficiency in the System. Any time during which the Department fails to make the System available for Contractor's remedial service. Any downtime investigated by Contractor which is then determined by the Contractor and the Department to be a non-downtime instance following such investigation.
System Reliability. Bizagi automatically maintains three replicas of database and servers to protect against hardware failure and increase system reliability.
System Reliability. Demandware looks at its application as well as the infrastructure as a tightly integrated system. [**]. Demandware has in place an expert team to provide services for server and network management, monitoring, backups, and other necessary maintenance. [**].
System Reliability. The reliability, at any point in time, of the System shall be determined by the System's operational capability for productive Client Agency use as configured, hosted, and installed, as applicable within the specified operating environment. Continued acceptability of the reliability of the System’s performance shall be based System operating errors or failures that preclude productive Client Agency use of the System according to the requirements of this Contract and Contract Exhibits.
System Reliability. Notwithstanding any other provisions herein, the Transmission Provider reserves the right, consistent with Good Utility Practice and on a not unduly discriminatory basis, to curtail Network Integration Transmission Service without liability on the Transmission Provider's part for the purpose of making necessary adjustments to, changes in, or repairs on its lines, substations and facilities, and in cases where the continuance of Network Integration Transmission Service would endanger persons or property. In the event of any adverse condition(s) or disturbance(s) on the Transmission Provider's Transmission System or on any other system(s) directly or indirectly interconnected with the Transmission Provider's Transmission System, the Transmission Provider, consistent with Good Utility Practice, also may curtail Network Integration Transmission Service in order to (i) limit the extent or damage by the adverse condition(s) or disturbance(s), (ii) prevent damage to generating or transmission facilities, or (iii) expedite restoration of service. The Transmission Provider shall give the Network Customer as much advance notice as is practicable in the event of such Curtailment. Any Curtailment of Network Integration Transmission Service shall be not unduly discriminatory relative to the Transmission Provider's use of the Transmission System on behalf of Native Load Customers. The Transmission Provider shall specify the rate treatment and all related terms and conditions applicable in the event that the Network Customer should fail to comply with established Load-Shedding and Curtailment procedures.
System Reliability. Seller may also temporarily require or cause Physical Curtailment of service to Purchaser’s Plant when Seller reasonably determines, pursuant to Prudent Utility Practice, that an interruption or curtailment of Interruptible Power and Energy to Purchaser is necessary to maintain service to customers, not including Purchaser, receiving retail
System Reliability. Seller may also temporarily require or cause Physical Curtailment of service to Purchaser’s Plant when Seller reasonably determines, pursuant to Prudent Utility Practice, that an interruption or curtailment of Interruptible Power and Energy to Purchaser is necessary to maintain service to customers, not including Purchaser, receiving retail service from Seller. Except under emergency conditions, Seller shall give Purchaser at least two hours advance notice of desired interruption and/or curtailment and at least one hour’s notice when interruption and/or curtailment are to be discontinued. If an interruption or curtailment under this Section 4.2 occurs during Curtailment Hours, the hours of curtailment or interruption under this Section will reduce the Curtailment Hours otherwise available during the same Curtailment Day. Upon reasonable request and for good cause, Purchaser shall have the right upon reasonable notice to audit books and records necessary to confirm the basis for system reliability interruptions.
System Reliability. The ISO shall have primary responsibility for ensuring short- term reliability of the System consistent with the applicable standards set by NERC and the NPCC. The ISO may direct any NEPOOL Participant to take any action necessary to preserve the reliable operation of the NEPOOL Control Area under the circumstances and in the manner set forth in the Tariff and the System Rules and Procedures.
System Reliability. 14.4.1 The Contractor shall guarantee the reliability and good performance of the OMCs (Operation & Maintenance Centres) in terms of handling all the traffic measurements, traffic observations, alarms and messages for all the system elements contracted under this contract. In case of any degradation in the performance, the Contractor shall provide an immediate solution at no additional cost to the Etisalat.
14.4.2 The Contractor shall guarantee the reliability and good performance of all contracted system modules/sub-modules equipment’s. The failure rate for a module/sub-module shall not exceed 0.01% of a total working modules/sub- modules per year. If the failure rate exceeds this limit, the Contractor shall provide a solution (such as redundancy) within one month from the date of exceeding the failure rate at no extra cost.
System Reliability. A system, for example a complex geotechnical structure, consists of many components or elements, whose individual or combined failure can lead to collapse. A simple gravity retaining wall would fail if the lateral forces on the wall exceed the base shear resistance (sliding mode of failure), if the weight of the wall and vertical forces acting on the wall exceed the bearing capacity at the base (bearing capacity mode of failure) or if the driving moment from the external loads exceeds the resisting moment from the weight of the wall (rotational mode of failure). The wall could therefore be thought of as a system that comprises three components whose individual failure would constitute the failure of the wall. The methods and examples discussed in the previous section generally characterize the performance and reliability of a single component of a complete system. The failure event of a system, in a reliability sense, is defined as the union, or intersection, or combinations thereof, of component failure events. In a graphical representation of a system, the components are represented by boxes that are connected together by lines to form the system. Input and output are marked by arrows (see Figure 4.5).
