In corrective maintenance, selective regression testing includes test selection from previously run test suite and test coverage identification. We propose three reductionbased regression test selection methods and two coverage McCabe-based identification metrics. We empirically compare these methods with other three reduction and precision-oriented methods using 60 test-problems. The compariso...

We study a repairable item inventory system under limited repair capacity and nonstationary Poisson demands, motivated by corrective maintenance of military equipment. Our goal is to minimize the cost of both spare and repair resource allocation. We propose an efficient analytical model that combines optimization modeling and queuing theory.

This article presents two case studies and theory on the topic of implementing a condition based maintenance approach. It visualizes that condition based maintenance, within the Swedish industry, is utilized to a lesser degree than corrective and predetermined maintenance, and argues that one reason for this is the difficulty in implementation. It also argues that additional factors, beyond tec...

Maintenance is of necessity for sustaining machinery availability and reliability in order to ensure productivity, product quality, on-time delivery, and safe working environment. The costly maintenance strategies such as corrective maintenance and scheduled maintenance have been progressively replaced by superior maintenance strategies in which condition-based maintenance (CBM) is one of the d...

A system subject to degradation is considered. The modelled by a gamma process. condition-based maintenance policy with perfect corrective and an imperfect preventive actions proposed. cost derived considering Markov-renewal statistical inference of the parameters maximum likelihood method investigated. sensibility analysis different carried out perspectives are detailed.

In this article we give an overview of the relation between planning of maintenance and production. On the one hand we consider production planning and scheduling models where failures and maintenance aspects are taken into account. Next we discuss the planning of maintenance activities, where we consider both preventive as well as corrective maintenance. Thirdly, we consider the planning of ma...

The article deals with the issues of building exploitation and maintenance focuses on characteristics strategies mentioned in ISO 15686-5:2017 Buildings constructed assets - Service life planning Part 5: Life-cycle costing. describes all three recommended by standard (preventive, corrective deferred maintenance). purpose is to conduct whole costs analysis variants modernisations, renovations fo...

Preventive maintenance is a means to ensure the component kept in desired state. Lack of preventive will cause unexpected consequences for component, and too much result unnecessary investment resources. Based on reliability data this paper establishes an analysis model determine optimal interval make cost corrective lowest.
