Evaluation of the Performance of Drilling Machines in the Aegean Lignite Corporation (Türkiye) by Analytical Hierarchy Process (AHS) and TOPSIS Method

Abstract

Multi-criteria decision making techniques are designed to enable better selection when it comes to complex
decisions involving various parameters. When a complex problem is mentioned, statements with immeasurable and
contradictory criteria such as efficiency, performance, safety, reliability, cost, and economy are understood. One of the
known purposes of the multi-criteria decision analysis approach is to assist the people who are responsible for organizing
and synthesizing such information that makes them feel confident in taking a decision, and to minimize potential decision
after regret by ensuring satisfaction when all criteria and factors are considered. Analytical Hierarchy Process (AHS) is
widely used in solving complex problems involving more than one criterion. The AHP method is based on a hierarchical
system consisting of many goals, criteria and alternatives. TOPSIS method can be applied directly on the data without
making a qualitative conversion.
