On the Requirements to Implement E-maintenance Cost effectively: Survey Study

Abu Daqqa, Nizar, Alan, Serkan January 2013 (has links)
Nowadays, companies started to realize the impact of a good maintenance strategy on the production process. Quality, performance as well as availability are affected by maintenance; existing maintenance strategies help to optimize the production process to achieve high quality products with a low production cost. A new strategy of maintenance has immerged recently, e-maintenance provides an easy solution to follow up with maintenance, it provides condition monitoring, documentation, and it also gives you the best maintenance solution that fits your goals and vision. Articles related to e-maintenance was studied and analyzed to know the steps to implement a cost-effective e-maintenance. The authors came up with a model that describes the implementation process in three main steps.

A numerical study of single-machine multiple-recipe predictive maintenance

Liao, Melody 01 August 2011 (has links)
Effective machine maintenance policy is a critical element of a smooth running manufacturing system. This paper evaluates a multiple-recipe predictive maintenance problem modeled using a M/G/1 queueing system. A numerical study is performed on an optimal predictive maintenance policy. A simulated job-based maintenance policy is used as a baseline for the optimal policy. We investigate the effects of varying degradation rates, holding costs, preventive maintenance times, and preventive maintenance costs. We also examine a two-recipe problem. / text

An in-depth study of personal creative maintenance

Carroll, Suzanne Catrice 15 May 2009 (has links)
This qualitative research study was created to examine four individual creative producers in the field of the visual and performing arts from different walks of life to determine if any similarities between the producers emerged. More specifically, the researcher was interested in (a) investigating how creative thinkers became creative producers and (b) investigating how these creative producers maintained and sustained high levels of creative production. After thoroughly utilizing the constant comparative method of data collection and analyzation, which includes peer debriefs, member checks, and other various qualitative techniques to keep the study internally valid, three themes emerged from the grounded data. Theme one is that a continuous evolution of the artist exists. This is brought about by parental support and critical incidents. Furthermore, these participants hold an enduring feeling of passion and responsibility for their field of creative endeavor. Theme two is that each creative producer spoke of having an intense inner sense of self. This sense of self first emerged within these participants at an early age, and its adult presence is evident in how these producers (a) cannot separate the artist from the person, (b) are aware of their personal and artistic growth, (c) are aware of their personal metacognitive strategies of generating ideas, and they sometimes use their art as a source of personal therapy. Theme three talks about how these creative producers see art as a greater whole. Its evidence is manifested within these participants perception that art has a very humanistic purpose by its effect on their communities.

Best Practice Maintenance in New Zealand Industry

Moore, James Thomas January 2013 (has links)
Mighty River Power have recognised Geothermal generation as a major strength and growth area for development in the medium term. The company has identified a need to improve maintenance effectiveness and reduce costs. This report investigates current New Zealand maintenance strategies in order to benchmark the effectiveness of Mighty River Power’s current maintenance scheme. The report identifies gaps in Mighty River Power’s current maintenance approach and provides recommendations to improve and optimise maintenance strategy based on case studies in both power generation and related asset-intensive industries.

Green Maintenance : A literature survey on the role of maintenance for sustainable manufacturing.

Ararsa, Bete Birhanu January 2012 (has links)
A growing uncertainty in the global economy is forcing many manufacturers to reassess their corporate outlook towards the environment. Today there is a growing attention to sustainability in industry accompanied by a paradigm shift towards realizing a sustainable society. It is now very common to hear about Green Production and Green Systems, but few literature exist that deal with the relatively newer subject of Green Maintenance. The term green production is often used to describe production with a sustainable perspective. Also, lean production has been proposed as a means of achieving sustainability. Lean and Green production systems require efficient production and low use of resources such as energy, materials, etc. One major facilitator of this is effective maintenance. Sometimes regarded as the necessary evil, maintenance still has a negative image in the industry. But as the paradigm on manufacturing shift towards realizing a sustainable society, we should also begin to realize the changing role of maintenance. Still, the impact of maintenance on sustainability and Green production is not very well described in research.   This Master Thesis within the School of Innovation Design and Engineering at Mälardalen University presents a literature review on green maintenance by trying to identify and assess the key factors of maintenance effects on green production, life cycle assessment and sustainability of maintenance activities. In addition, a brief introduction to the greening of remanufacturing activity, part of a green process by itself, is provided. The research is based upon extensive literature study, questionnaire survey and interviews with relevant industry as well as academic personnel. A discussion of the results of the interview followed by a conclusion on the key factors of maintenance on sustainability is provided. Future research areas have also been suggested.       Keywords: Green maintenance, Production maintenance, Sustainable maintenance,     Total Productive Maintenance
