Some machine part failures have often occurred in areas of components where the strength was lowest, especially at its weld region. Presence voids weldments or joints greatly reduces quality weldment. To prevent these defects, a proper optimum selection process parameters is highly encouraged to achieve an acceptable mechanical property. The Complex Proportional Assessment (COPRAS) method appli...

Background: Coal production and marketing enterprises can significantly reduce transportation costs improve their competitiveness by choosing appropriate road companies. Methods: Based on this, a trapezoidal fuzzy SWARA-COPRAS method is proposed to select coal The SWARA used determine the index weight of ranking companies determined using COPRAS method. Results: Taking enterprise in Hubei, Chin...

• We propose a fuzzy integrated model for supplier selection in digital supply chains. Fuzzy BWM is with MULTIMOORA, COPRAS and TOPSIS. applied to measure the importance weights of evaluation criteria. TOPSIS are used prioritize suppliers. Maximize agreement heuristic aggregate single method rankings into consensus ranking. Digital chains (DSCs) collaborative systems designed quickly efficientl...

Information and communication technology (ICT) enable information to be accessed processed through all kinds of visual, audio, printed written tools. This study aimed evaluate the ICT development G7 countries by using Multi Criteria Decision Making (MCDM) methods. Accordingly, Entropy method was used specify criteria weights, Proximity Indexed Value (PIV), Range (ROV), COmplex PRoportional ASse...

Kota Semarang memiliki beberapa SMK jurusan TKJ yang sangat ketat persaingannya dalam menghasilkan lulusan berkualitas tinggi. Adapun banyak diminati para SMP antara lain SMKN 4, 5, 7, 8 dan masih lagi. Ke empat tersebut sebagai sample data dari perhitungan COPRAS. Sebagian besar harus pandai menentukan berhasil meluluskan bisa bersaing di dunia kerja. Kriteria penilaian untuk metode COPRAS pem...

Here in this article, a hybrid MCDM method on the Pythagorean fuzzy-environment is presented. This based Fuzzy Method Removal Effects of Criterion (PF-MEREC) and Stepwise Weight Assessment Ratio Analysis (SWARA) approaches. Here, objective subjective weights are assessed by PF-MEREC, SWARA model preference order ranking various alternatives done through Complex Proportional (COPRAS) framework f...
