Minimal repair models with non-negligible repair time
Reliability Engineering and System Safety, 2022Abstract In existing minimal repair models, it is usually supposed that the repair time of systems is negligible, and thus the occurrences of breakdowns obey non-homogeneous Poisson Process within a replacement interval. However, for the case that the mean working time of a system is not far longer than its mean repair time, ignoring repair time may ...

Maintenance Policies with Minimal Repair
Economic Quality Control, 2004Summary: This article gives a survey on some important maintenance policies involving minimal repairs and replacements of technical systems. The main focus is on policies, which have been published after 1990. Based on a thinned nonhomogeneous Poisson process, repair cost limit policies with minimal repair are discussed in more detail.

IEEE Transactions on Reliability, 1991 Summary: The cumulative function for the number of failures for a unit is subjected to a minimal repair after each failure is a non-stationary Poisson process. This note presents a simple method for obtaining this result.

On Predicting Repair Times in a Minimal Repair Process
Communications in Statistics - Simulation and Computation, 1989A minimal repair process is the nonhomogeneous Poisson process generated by the successive repairs of an equipment in which, upon each failure, the equipment is instantaneously restored to its condition immediately prior to failure. Point predictors of a future minimal repair epoch are developed and compared, on the basis of ‘pointwise’ as well as ...

On Repair Age Residual Repair Life in the Minimal Repair Process
Probability in the Engineering and Informational Sciences, 1989Some properties of repair age (the elapsed time since the last repair) and the residual repair life (the time until the next repair) are studied for the minimal repair process under various assumptions on the aging characteristics of the equipment under maintenance. Bounds on expected repair age and expected residual repair life are obtained.

The Age Replacement Problem with Minimal Repair and Random Repair Costs
Operations Research, 1979Age replacement policies are investigated. When a unit reaches age T, a preventive replacement is made. If a failure occurs prior to age T and if the random repair cost is less than a fixed constant, a minimal repair is made. Otherwise the unit is replaced at failure.

Minimally Invasive Achilles Repair Techniques
Orthopedic Clinics of North America, 2020Achilles tendon rupture is an increasingly common problem with an aging population participating in high-level physical activities. Appropriate treatment has been debated for decades, but good outcomes have been reported after conservative and surgical management. The development of minimally invasive surgical techniques for Achilles repair has reduced

Minimally Invasive Repair of Meta-bones
Veterinary Clinics of North America: Small Animal Practice, 2012Metacarpal and metatarsal fractures are common injuries in small animals and, in most of the cases, can be treated by minimally invasive techniques. Bone plates applied through epi-periosteal tunnels can stabilize meta-bones. Meta-bones III and IV are stabilized by dorsally applied plates.

Minimizing the cost of repairing WSI memories
[1989] Proceedings International Conference on Wafer Scale Integration, 1991Abstract A new approach to repair WSI memory chips with redundancy is proposed in this paper. This approach is based on the minimization of the repair cost. Algorithms for cost driven repair are presented. The algorithms can be executed either on-line (concurrently with the testing of the memory), or off-line (at completion of testing) Analytical ...

Ordering Policies under Minimal Repair
IEEE Transactions on Reliability, 1986Many maintenance policies in the literature have assumed that whenever a unit is to be replaced, a new unit is immediately available. However, if the procurement lead time is not negligible, an ordering policy should determine when to order a spare and when to replace the operating unit.
