Abstract: The traditional mission maintainability evaluation method cannot effectively estimate the overall maintenance time of equipment in specific task profile. An evaluation method which can be used to evaluate the mission maintainability of repairable unit constitution is proposed. During evaluation, the maintenance time probability density function of functional unit is estimated using a Bayesian updating approach, and the maintainability of failure event of repairable unit constitution is calculated in a simulation way. The example analysis shows that the proposed method may not only solve the estimated inaccuracy of maintenance time probability density function of functional unit due to incomplete statistical data, but also calculate the convolution of multiple functions conveniently. The assessed result of mission maintainability is more credible.

Key words: ordnance science and technology, repairable unit constitution, mission maintainability, Bayesian updating, failure event
