The computer-based 3D modeling of ore bodies is one of the most important steps in the resource estimation, grade determination, and production scheduling of open-pit mines. In the modeling phase, the volume of the orebody model is required to be filled by the blocks and sub-blocks. The determination of Block Size (BS) is important due to the dependence of the geostatistical issues and calculat...

This paper presents a group multi-criteria DEMATEL and VIKOR decision analysis method with interval type-2 fuzzy sets. In order to compare normal fuzzy trapezoidal numbers, we convert them into crisp values using graded mean integration representation. By a case study for selection of business intelligence platform, we prove that the proposed combination is a feasible solution that can work wit...

When the government decides to use public-private partnership (PPP) in projects, such as infrastructure construction, selecting a private-sector partner that meets project's needs is one of key factors for successful implementation, but this ignored existing research. On basis, paper proposes GRA-VIKOR method based on combined weight improved CRITIC-entropy (EWM). The traditional CRITIC by comb...

Recently, resolving the problem of evaluation and ranking the potential suppliers has become as a key strategic factor for business firms. With the development of intelligent and automated information systems in the information era, the need for more efficient decision making methods is growing.

This paper presents a new risk evaluation approach in order to rank the high risks in large-scale projects and improve the performance of these projects. It is based o...

The aim of the current research is to measure objective congruence (incongruence) of the results obtained in a process of multiple criteria analysis when applying different MCDM methods. The methodology for evaluation of ranking results is developed on the ground of a case study of the redevelopment of derelict buildings as well as on composed experimental tasks. Fuzzified COPRAS, TOPSIS and VI...

Bir futbol takımı kurulurken asil ve yedek futbolcuların doğru seçilmesi, takımın uyumlu olması galibiyet elde edilmesi açısından oldukça önem taşımaktadır. Futbol kadrosunun pozisyonları belirlidir farklı pozisyonlar fiziksel becerileri gerektirmektedir. Bu çalışmanın amacı; söz konusu dikkate alınarak Türkiye Milli Takımı futbolcularının geçmiş sezon verilerinin değerlendirilmesi doğrultusund...
