Reliability-based maintenance policies allow qualitative and quantitative evaluation of system downtimes via revealing main causes of breakdowns and discussing required preventive activities against failures. Application of preventive maintenance is especially important for mining machineries since production is highly affected from machinery breakdowns. Overburden stripping operations are one of the integral parts in surface coal mine productions. Draglines are extensively utilized in overburden stripping operations and they achieve earthmoving activities with bucket capacities up to 168 m(3). The massive structure and operational severity of these machines increase the importance of performance awareness for individual working components. Research on draglines is rarely observed in the literature and maintenance studies for these earthmovers have been generally ignored. On this basis, this paper offered a comprehensive reliability assessment for two draglines currently operating in the Tuncbilek coal mine and discussed preventive replacement for wear-out components of the draglines considering cost factors.

A cost-effective simulation algorithm for inspection interval optimization: An application to mining equipment Gölbaşı, Onur; Demirel, Nuray (2017-11-01) In machinery maintenance policies, regular inspection intervals should be specified in such a way that the cumulative of direct and indirect financial consequences of maintenance activities should be minimized while supporting the functional health of system components. This study aims to develop a simulation algorithm, called the time-counter, to optimize inspection intervals. In the algorithm, uptime and downtime behaviors of the system components and production losses in the corrective repairs are consid...
RISK-BASED RELIABILITY ALLOCATION METHODOLOGY TO SET A MAINTENANCE PRIORITY AMONG SYSTEM COMPONENTS: A CASE STUDY IN MINING Gölbaşı, Onur; Demirel, Nuray (2017-01-01) This study aims to build up a maintenance priority methodology for system components with the help of existing literature on reliability allocation. The offered methodology was applied to two high-capacity earthmovers using actual datasets collected by operations in Tuncbilek Coal Mine, Turkey. Prioritization of maintenance for components was achieved by adapting their operational risk factors to a generic reliability allocation algorithm. In this sense, direct and indirect financial consequences of compone...
Implementation of total quality management in public sector: an empirical analysis of a Turkish case Balcı, Asım; Aksoy, Şinasi; Department of Political Science and Public Administration (2002) This thesis examines the issues of Total Quality Management (TQM) implementation in a public sector context. After presenting the background, the thesis analyzes special reasons, possible benefits, problems and prospects of TQM related to public sector. Next, quality practices of the Turkish public organizations are reviewed as well. Also, the case study, conducted in the Ministry of Industry and Trade, identifies the degree of TQM adoption and discusses the results through the framework presented.
Data driven landslide hazard assessment using geographical information systems and remote sensing Süzen, Mehmet Lütfi; Doyuran, Vedat; Department of Geological Engineering (2002) The purpose of this thesis is to generate and evaluate a concise system of data driven landslide hazard assessment procedure. The Asarsuyu catchment area and Bolu Mountain highway pass are selected for this purpose In this study, three data domains, which are remote sensing products, geological maps and topographical maps are used. The landslides of four different historical periods are interpreted using aerial photographs. Land cover is extracted from satellite images. Thirteen sets of parameter maps are p...
Effect of using extreme years in hydrologic model calibration performance Göktaş, Recep Kaya; Tezel, Ulaş; Kargı, Pınar Gökçe; Ayvaz, Mustafa Tamer; Tezyapar, İpek; Mesta, Buket; Kentel Erdoğan, Elçin (2017-12-15) Hydrological models are useful in predicting and developing management strategies for controlling the system behaviour. Specifically they can be used for evaluating streamflow at ungaged catchments, effect of climate change, best management practices on water resources, or identification of pollution sources in a watershed. This study is a part of a TUBITAK project named "Development of a geographical information system based decision-making tool for water quality management of Ergene Watershed using pollut...
