A Joint Reliability Analysis based on Materiel's Multivariate Lifetime Field Data

n the material's operation support stages,the reliability assessment and maintenance policy execution for multi-life indexes involved equipments or systems is always meaningful researched and applied.By analyzing the different forms of airplane equipments' lifetime indexes,we could advance a model of correlated multivariate approach especially considering bivariates of age and usage to estimate equipments' reliability,and then suggest a practical and effective method of field reliability estimation.
