On Predicting Repair Times in a Minimal Repair Process

Communications in Statistics - Simulation and Computation, 1989
A 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 ...

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 Repair Age Residual Repair Life in the Minimal Repair Process

Probability in the Engineering and Informational Sciences, 1989
Some 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.

Computing Card-minimal Repairs

2011
In this chapter, we present a technique for computing card-minimal repairs in the presence of steady aggregate constraints. Thus, differently from the (decision) problems introduced in Chapter 3, we here address a search problem, which is relevant in practice as, in several applications, the availability of a consistent version of the data is mandatory

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

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 ...

Optimal Preventive Replacement Under Minimal Repair and Random Repair Cost

Mathematics of Operations Research, 2000
A repair/replacement problem for a single unit system with random repair cost is considered. When the unit fails, the repair cost is observed and a decision is made whether to replace the unit or repair it. We assume that the repair is minimal, i.e., the unit is restored to its functioning condition just prior to failure, without changing its age. The

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.

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 ...

Minimally Invasive Ptosis Repair

2008
Minimally invasive ptosis surgery offers many advantages—a less visible scar, a reduced surgical time, and an improved postoperative period—and it is as effective and reliable as the traditional surgical approach. I have been delighted with the minimally invasive approach in aponeurogenic ptosis.
