Abstract
PurposeMaintainability is a critical design characteristic that shows how well a product can be maintained; maintenance time is a comprehensive parameter of product maintainability design. This paper aims to provide an integrated methodology for complex product maintainability verification and maintenance time prediction using virtual prototypes and humans in a virtual dynamic simulation of the maintenance process.Design/methodology/approachAn integrated platform for maintainability verification and maintenance time prediction is designed. Decomposition of maintenance tasks, corrective measurement time method, and an impact matrix of maintenance therbligs and time are presented.FindingsThe proposed methodology can efficiently conduct complex product maintainability verification and maintenance time prediction.Practical implicationsEarly and effective verification and prediction of the maintainability and maintenance time program can significantly improve the maintainability and availability of a complex product.Originality/valueA universally applicable method for product maintainability verification and maintenance time prediction is presented.
