Engineering Services and Analysis – Maintainability Analysis
A maintainability analysis is performed to determine what tasks are required to keep a product in operational condition. It examines the various components, subassemblies, assemblies and systems that make up a product. It then determines what tasks are required to either repair or service the product to keep it in working order.
Maintainability predictions provide time-based information regarding how long it will take to repair or service a product. It assigns a value (in minutes or hours) and the number of personnel required to accomplish a task. For complex tasks, all the subtasks are considered as well. These tasks along with the reliability predictions are then compiled and a Mean Time To Repair (MTTR) is generated.
Maintainability analysis and prediction reports typically include a front matter that provides the end user an idea of what assumptions and practices were established for use in the analysis. Also included are presumed skill levels and facilities available to repair personnel.
