Mona, Bonginkosi Johan January 2016 (has links)
A research report submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, in fulfilment of the requirements for the degree of Masters in Engineering. May 2016 / Successful implementation and execution of asset management strategy is found to be a critical element in driving value, which depends on physical assets’ performance. This paper shows that strategic asset management targets measured as AM Maturity are often not attained. This study identifies key issues that prevent mining organisations from attaining the desired level of Asset Management Maturity. A qualitative methodology was utilised on a single case study design in order to investigate a particular phenomenon which is Asset Management Maturity at A-Coal site. The study revealed revealed the following key issues: lack of strong Asset Management leadership; lack of a favourable organisational structure which will provide Asset Managers with credibility and the authority to make decisions in support of organisational objectives; no leadership support; and a lack of training obviate the benefits that can be realised from improvement initiatives which motivated, committed and enthusiastic employees will be delivering. In addition to these challenges are organisational culture and a certain level of employees’ competitiveness in the field of asset management. / MT2016

Utvärdering av pm3 som förvaltningsstyrningsmodell : En fallstudie på Trafikverket / Evaluation of pm3 as a maintenance management model : A case study at the Swedish Transport Administration

Grönberg, Oskar January 2019 (has links)
The maintenance management model (Pm3) is a management model whose goal is to contribute to the collaboration between the business and IT. An implementation of pm3 involves applying the model, it must be implemented with the business existing governance and work methods. The purpose of the study is to investigate to be able to describe and evaluate the use of pm3 as a management model in a state agency. The study is carried out at the Swedish Transport Administration and their implementation of pm3. The aim of the study is to answer the research question which is “how pm3 can be implemented and applied to be more effective?”. The strategy that has been applied is a case study. The data collection methods are interviews and document studies where qualitative data has been generated. The results of the study show a number of different positive effects that implementation of pm3 can have on a business such as better collaboration, cost effectiveness and clearer overall picture. Some challenges and problems are also identified and a lot of them can be linked to the lack of implementation of the model at the Swedish Transport Administration. To maximize the implementation of pm3, this study has come to the conclusion that it is important with internal education in the management model. This to increase the chance of a successful implementation. Taking external help from the pm3 license is also a way to improve the implementation, as it offers external help and support from external experts. After implementation, it is also important to have an active management of the model, so that the business receives support to work properly over time. Recommendations for future studies is how to follow up on your implementation and establish your governance with pm3 over time.

A Fuzzy Criticality Assessment System of Process Equipment for Optimized Maintenance Management.

Qi, Hong Sheng, Alzaabi, R.N., Wood, Alastair S., Jani, M. 09 July 2013 (has links)
yes / In modern chemical plants, it is essential to establish an effective maintenance strategy which will deliver financially driven results at optimised conditions, that is, minimum cost and time, by means of a criticality review of equipment in maintenance. In this article, a fuzzy logic-based criticality assessment system (FCAS) for the management of a local company’s equipment maintenance is introduced. This fuzzy system is shown to improve the conventional crisp criticality assessment system (CCAS). Results from case studies show that not only can the fuzzy logic-based system do what the conventional crisp system does but also it can output more criticality classifications with an improved reliability and a greater number of different ratings that account for fuzziness and individual voice of the decision-makers.

The impact of the absence of a total productive maintenance (TPM) program at a plastic painting plant

Hempel, Calvern Anthony January 2007 (has links)
This research was concerned with investigating “the absence of Total Productive Maintenance (TPM)” at a plastic painting plant. TPM is a combination of operations and maintenance activities and is performed by operators under their own authority and is called “autonomous maintenances”. The author has tested the degree of implementation of TPM by using a sevenstep TPM implementation model this highlighted an absence of TPM in the organisation investigated. TPM is a relatively new concept in the South African automotive industry and has not been fully accepted by management as a solution to the maintenance problems in the organisation. Due to a long implementation period and the difficulty in measuring the benefits of the TPM program for the organisation TPM tends not to be implemented by companies. The research studies several maintenance philosophies each with its own advantages and disadvantages. The benefits that arise from the implementation of an effective TPM philosophy were explored. The development of an effective improved model for the implementation of TPM was investigated. Maintenance engineers and managers in any organisation can use this model to implement an effective TPM program. The seven-step TPM implementation model formed the basis for the compilation of a questionnaire. A survey was conducted to determine if an absence of TPM existed in a plastic painting plant. The results from the survey were drawn up and recommendations to further develop a model for the implementation of TPM was put forward.

Maintenance Management Model under the TPM approach to Reduce Machine Breakdowns in Peruvian Giant Squid Processing SMEs

Gallesi-Torres, A., Velarde-Cabrera, A., León-Chavarri, C., Raymundo-Ibañez, C., Dominguez, F. 06 April 2020 (has links)
In recent years, the giant squid processing industry in Peru exhibited a 59% increase in exports with respect to 2018. According to estimates, this industry generates approximately 30,900 jobs per year. However, some SMEs experience low productivity, such as the PECEPE company, due to plant downtime. This represents 26% of the available time, which translates into the loss of 1760 tons every year. The most constraining external factor the sector faces is uncertainty in resource availability caused by changing weather conditions and informal fishing activities. Although there is a large number of research studies on the fishing industry and resource extraction, literature on processing plant operations is scarce. Within this context, this study seeks to promote a high impact sector in Peru, as well as fostering processing plant competitiveness and productivity. Hence, to address these issues, the authors propose a maintenance management model under the TPM approach. As part of the results from model implementation, a 39% decrease was reported in plant downtime, while maintenance costs also decreased by 16%, which, in turn, increased machine availability and production by 784 tons per year.
