Selection of coal transportation mode from the open pit mine to the thermic power plant using Fuzzy Analytic Hierarchy Process

Abstract

Abstract.Coal produced in open pit mines should be moved to thermic power plants for production of power. Thermic power plants require very large amounts of coal. In transportation process of this coal, both costs and technical parameters should be considered. Common alternative transportation modes in this process are belt conveyors, truck types, suspension rail conveying systems, pipelines and railways. Selection of one of these modes is influenced by transportation distance, inclination of the haulage road, amount of coal reserve, investment costs, production capacity and unit production cost of the open pit mine. In this study, advantages and disadvantages of alternative transportation modes are analysed using Fuzzy Analytic Hierarchy Process (F-AHP). The results revealed, belt conveyors and trucks transportation by are superior to others.

Directions for the development of transport machines for open-pit mining

“…The systematization of directions for the enhancement of transport equipment was conducted on the basis of fundamental criteria of the design and the state of art [12][13], considering current logistics requirements for transport [14]. When selecting development criteria based on the principle of progressive development for the next generations of machines, based on setting priorities when developing solutions to improve one but not to degrade other criteria, the potential improvement of constructional, structural and operating parameters of transport machines was accounted for to a sufficiently great extent and provided that the rest will have virtually stable effect.…”

Optimization of fleet structure and investment evaluation – the cargo owner's fleet perspective

“…In terms of coal transportation research, Wu et al (1995) and Liu and Sherali (2000) built a 0-1 mixed integer programming (MIP) model to investigate the problem of sea transportation of coal and solved the model with intelligent optimization algorithms, including branch and bound, Benders decomposition and GA. revealed the spatial pattern and temporal evolution of coal transportation along coastal ports in China. Considering costs and technical parameters, Ozfirat et al (2018) evaluated alternative transportation modes in the transportation process of coal via the fuzzy analytic hierarchy process (FAHP). Yucekaya (2013) developed a multi-objective model to decide the supplier, transportation mode and coal order for coal power plants.…”

Assessing the Sustainability of Manufacturing Processes in the Manufacture of Transport Equipment, Based on Fuzzy Grey Relational Analysis

“…This is because of the comparative integrity of the fuzzy AHP model in respect of its fuzzified pairwise comparison matrices [20]. Examples of the application of fuzzy AHP in manufacturing decisions include the selection of a coal transportation mode from an open-pit mine to a thermic power plant [21], supplier selection problems [22,23], and the multiattribute comparison of catering service companies in Turkey [24]. The fuzzy event tree is a type of decision-making model that is applied to strategic decisions in manufacturing, such as supplier selection.…”
