Modeling and Assessment of Aging and Efficiency of Corrective and Planned Preventive Maintenance

The objective of this research is to demonstrate the methodology adopted by the maintenance textile industries, which are located in the Zona da Mata Mineira region, in Minas Gerais Brazil. The research emphasized the general nature of the maintenance management of these companies. The survey applied was presented through graphs with appropriate descriptions and comments for easy viewing of the results. The survey was conducted in a universe of 54 companies in the textile industry / manufacturing /garments in Zona da Mata Mineira region between September and November 2014. This article is linked to a research project funded by FAPEMIG with same name, still in progress.Keywords: Textile industry, machinery and equipment maintenance of, Zona da Mata Mineira. RESUMEN El objetivo de este trabajo es demostrar la metodología de mantenimiento adoptada por las industrias textiles que se encuentran ubicadas en la región de la Zona da Mata

“…In Kijima‐type models, an item with initial failure rate λ 1 ( t ) = λ ( t ) is considered. At some time t 1 (this can be a failure time or a stopping time for preventive maintenance; see the work of Doyen and Gaudoin), the item will be repaired with the degree ξ 1 . By this repair action, the age of the item is decreased to v 1 = ξ 1 t 1 .…”

“…12 These models are based on a reduction of age or a reduction of the failure rate, see, among others, the work of Doyen and Gaudoin. 13 Using degradation models, there arises the opportunity to consider degradation-based maintenance. In some papers, eg, those by Mercier and Castro 14 and Zhang et al, 15 imperfect maintenance is reducing the degradation level of a maintained system or the degradation factor.…”

We consider a Wiener process with linear drift for degradation modeling. Regularly, maintenance actions are carried out which produce a reduction of the degradation level. In this paper, we consider the influence of such maintenance actions to the further development of the degradation process and the resulting lifetime distribution. A connection between virtual age in Kijima‐type models and degradation level in the underlying degradation process is developed. Furthermore, estimators for the process parameters as well as for the degree of repair are developed.

“…Gasmi et al [19] investigate the Contents lists available at ScienceDirect journal homepage: www.elsevier.com/locate/ress situation where the age of the system is set to a known value different from zero at the beginning of the observation. Two natural but reductive simplifications are also employed when using imperfect maintenance models from an observation window: either the system is assumed to be new at the beginning [26] or no repair is assumed to have been performed prior to the beginning [14].…”
