Optimization of the lubricating oil inventory policy applied in a mining company

2021-02-01
The mining industry should sustain mass and continuous production with an essential contribution of high-capacity machinery. Therefore, spare parts inventory management is vital in ensuring the intended mining production rate as an integral part of maintenance policies. In this paper, a mixed-integer model is presented to solve a multi-item and multi-supplier spare parts inventory model. This model is addressed to a lubricating oil inventory problem in one of the biggest multi-process mining companies in Turkey. The optimisation results show that the company’s current lubricating oil inventory policy can be improved financially by yielding an annual saving up to ₺18,566.

Evaluation of state owned indigenous coal fired power plants including coal reserves
Güler, Mehmet; Güyagüler, Tevfik; Department of Mining Engineering (2010)
Fossil fuels has preserved their importance in gradually increasing production and consumption of both energy and electricity of the world. Asia, especially China and India, has arisen new actors of the sector. Energy and electricity consumption of Turkey has also increased in parallel with her economic development, but due to her limited resources, she has become more and more energy dependent in order to meet her growing demand. Although hard coal is only found around Zonguldak region, with its abundant a...
Comparison of sub-processes and final products of iron and steel production with life cycle assessment
Ölmez, Gülnur; Yetiş, Ülkü; Department of Environmental Engineering (2011)
Iron and steel production is one of the most resource and energy demanding industries around the world. Throughout the life cycle of iron and steel products, the intensive use of raw materials and energy results in contributions to a wide range of environmental impacts. This study conducts a life cycle assessment (LCA) for iron and steel production in Turkey using SimaPro software and IMPACT 2002+ impact assessment method with the purpose of comparing the impacts of life cycle stage (coke making, sintering,...
Use of Geospatial Queries for Optimum Drilling and Blasting Practices in Surface Mining
Erkayaoğlu, Mustafa (2018-11-22)
Increasing demand of the modern society for energy and raw material strengthens the role of mining in sustainable development. The basic production cycle of surface mining is initiated by drilling and blasting the material that will be loaded, hauled, and dumped by various mobile equipment. Performance measurement and analysis of all these production stages by the utilization of available technology is of crucial importance for continuous improvement of modern mine operations. Today, most of the mobile equi...
Tactical inventory and backorder decisions for systems with predictable production yield
MART, Turgut; Duran, Serhan; Bakal, İsmail Serdar (2013-06-01)
We consider a manufacturing system with stochastic demand and predictable production yield. The manufacturer has predetermined prices and limited production capacity in each period. The manufacturer also has the option to save some inventory for future periods even if there is demand in the current period. The demand that is not met is lost or may be backordered for only one period. Our objective is to maximize the expected profit by choosing optimal produce-up-to level ((Y) over bar*(t)), save (S*(t)) and ...
Monitoring and statistical modelling of dust concentration of some Turkish lignites under laboratory conditions
Karakaş, Ahmet; Güyagüler, Tevfik; Department of Mining Engineering (2010)
Although technological developments enable maximum safety, high dust formation is still a crucial problem in coal mining sector. This study is aimed to investigate the relationship between amount of coal dust produced during cutting operation and some important coal properties together with cutting parameters for different particle size ranges in laboratory conditions. For this purpose, six Turkish lignite samples were used in the experiments. Two experiment sets were designed to generate coal dust by using...
