Mission Reliability Clause Samples
Mission Reliability. Mission reliability is the probability the system will perform Mission Essential Functions (MEFs) for a period of time under the conditions stated in the mission profile. Mission reliability can also be stated as the probability a system can complete its required operational mission without an OMF. An OMF is a failure that prevents the system from performing one or more MEFs. Two measures of mission reliability are mean time between operational mission failure and item reliability. Where: OT is Operating Time; the time during a mission profile when the system is turned on and actively performing at least one, if not all, of its functions. # OMFs is the number of Operational Mission Failures. Discrete Model.
Mission Reliability. The probability that a system will perform its required mission critical functions for the duration of a specified mission under conditions stated in the mission profile. (DAU Glossary) Mission reliability can also be stated as the probability a system can complete its required operational mission without an operational mission failure (OMF). An OMF is a failure that prevents the system from performing one or more mission essential functions. For some systems, mission reliability may be better expressed as a function of Mean Time (miles, rounds, etc.) Between Operational Mission Failure (MTBOMF). (See paragraph 8 for definition.)
Mission Reliability. Mission reliability is the probability the system will perform mefs for a period of time under the conditions stated in the mission profile. Mission reliability can also be stated as the probability a system can complete its required operational mission without an Operational Mission Failure (OMF). An OMF is a failure that prevents the system from performing one or more mefs. Two measures of mission reliability are mean time between operational mission failure and item reliability. reliability model will be used. Generally, the distribution of failure can be assumed to be binomial for discrete items, and exponential for continuous items. Other failure distributions may be used when appropriate. See paragraph 6540 for a discussion of alternative continuous distribution reliability models. Discrete Model. Based on the binomial distribution:
