Replacement Policies under Minimal Repair

Journal of the Operational Research Society, 1981
In many situations where system failures occur the concept of ‘minimal repair’ is important. A minimal repair occurs when the failed system is not treated so as to return it to ‘as new’ condition but is instead returned to the average condition for a working system of its age.

Pitfalls of Minimally Invasive Fracture Repair

Veterinary Clinics of North America: Small Animal Practice, 2020
Minimally invasive fracture repair (MIFR) is the ultimate culmination of current osteosynthesis concepts that emphasize the preservation and enhancement of the biologic components of fracture healing. Although the "less is more" approach to tissue dissection and fracture exposure and handling that defines MIFR has numerous reported advantages over more

MACULAR HOLE REPAIR WITH MINIMAL VITRECTOMY

Retina, 2002
Conventional macular hole surgery usually involves removing 80% of the intraocular contents to repair a hole a few hundred micrometers in diameter. Although the success rate for conventional surgery is good, it may be possible to reduce the number of complications with less invasive surgery.A newly designed microspatula knife was used to dissect the ...

A repair policy with limited number of minimal repairs

Journal of Nonparametric Statistics, 2001
The imperfect repair model of Brown and Proschan [2] is modified by restricting the number of consecutive al repairs by n(n=0,1,2,...). We extend the earlier analysis by studying the preservation of ageing properties of the modified model and by obtaining several interesting monotonicities of long-run average time between succes-sive failures.

Some results for repairable systems with minimal repairs

Applied Stochastic Models in Business and Industry, 2013
In this paper, we consider a repairable system with minimal repairs whose number of repairs is a positive random variable with a given probability vector. Some preservation theorems and aging properties of repairable systems are established. Under the condition that at time t the system is working, a new random variable for the residual lifetime of the

A Survey of Replacement Models with Minimal Repair

2011
This presentation, which is mainly of an expository nature, is divided into two parts. The first part is concerned with age replacement age replacement models with minimal repair minimal repair and the second part deals with block replacement block replacement models with minimal repair.

Minimally Invasive Repair of Sacroiliac Luxation

Veterinary Clinics of North America: Small Animal Practice, 2020
Sacroiliac fracture-luxation is a common injury that is associated with ilial and acetabular fractures of the opposite hemipelvis. Sacroiliac fracture-luxation results in an unstable pelvis and potentially collapse of the pelvic canal. A minimally invasive approach to the reduction and insertion of a screw for fixation of sacroiliac fracture-luxation ...

On some minimal repair model

Microelectronics Reliability, 1980
Abstract This paper deals with a one-unit system under the new maintenance policy subject to a minimal repair and a preventive maintenance. Under this policy, the Laplace transform of the point-wise availability and the stationary availability of the system are obtained using the supplementary variable method.

Minimally Invasive Repair of Pectus Excavatum

Seminars in Thoracic and Cardiovascular Surgery, 2009
The minimally invasive approach for repair of pectus excavatum has become widely accepted by pediatric and thoracic surgeons primarily because of increased patient awareness and good long-term outcomes. Although the technique is considered fairly new, it was quickly embraced by many, resulting in a significant increase in the number of such procedures ...

Age-dependent minimal repair

Journal of Applied Probability, 1985
A stochastic model is developed to describe the operation in time of the following maintained system setting. A piece of equipment is put in operation at time 0. Each time it fails, a maintenance action is taken which, with probability p(t), is a complete repair or, with probability q(t)=1– p(t), is a minimal repair, where t is the age of the equipment
