dbstmctTo date, very little work has investigated the benefits of repairable robots. Robots that can repair themselves and other robots in their team are intuitively a superior design. Intuition, however, is not an acceptable basis for spending millions of dollars in development. In this work, we quantify the gain in productivity of a team of repairable robots compared to a team without repair ...

In this article, the intricacies involved in the maintenance of the industrial repairable systems are analyzed. Based on the practical requirement, the mathematical models for repairable system maintenance which are using point process theory are listed and reviewed. The available estimation, inference and prediction methodologies are also listed. The future issues which are to be addressed in ...

The multiple repairable systems may present system-to-system variability owing to the factors such as operation environments and working intensities of individual systems. It may be more reasonable to assume a heterogeneity among all the systems. In this paper, we propose a nonlinear mixed-effects model (NLMM), called power law process-nonlinear mixed-effects model (PLP-NLMM) and log linear pro...

Software tests are intellectual assets that are as valuable as source code. Over the long term, maintainable software tests significantly lower a project's cost. It is very difficult, however, to write maintainable software tests, especially executable ones. Existing approaches including natural languages, tabular formats, scripting and programming languages, and several test description langua...

In this investigation, the explicit expressions for reliability function and mean time to failure (MTTF) of a repairable system with provision of spares and removable multi-repair facility have been established. In removable repairmen strategy, the repairmen turn on when there are N or more than N failed units and turn-off when system is empty. The failure times of operating/spare units and rep...

The application of parametric reliability analysis methods for repairable units, such as Power law process, is quite clear and straightforward for a single repairable unit. However, in practice, the analyst needs to know the reliability characteristics of units at a fleet level. The application of parametric reliability analysis methods at the fleet level, even if it is limited in scope, is qui...
