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...

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...

• 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...

Recent research is recognizing that multiple criteria analysis should take account of the concepts of uncertainty and risk. In some cases, precise determination of the exact value of alternatives and weights of criteria is difficult. Consequently, to deal with these potential problems, their values are regarded as fuzzy and intervals. This paper proposes an interval-valued fuzzy multiple criter...

With the increasing risk to human health and environmental issues, selection of appropriate management treatment healthcare waste has become a major problem, especially in developing countries. There are various alternatives dispose care waste. The important is assess best alternative among them. assessment each should be done based on public health, psychological, economic, environmental, tech...

This study aims to present a multi-criteria decision analysis (MCDA) for comprehensive performance evaluation of the alternative design timber–concrete composite (TCC) floor system. Considered objectives are serviceability and sustainability with associated criterion as (1) comfort class regarding springiness vibrations, (2) architectural quality open spaces, (3) environmental aspect CO2 emissi...

The present research used the stir-casting method to develop an Al-based composite. developed composite exhibited challenges while being processed on conventional machining. Thus, a non-traditional machining process was opted variables selected for current were pulse off time (Toff), (Ton), servo voltage (SV), (I), and tool electrode. Three electrodes (SS-304, copper, brass) (Al/SiC/Gr). experi...

Cross-border E-commerce has grown exponentially in the past decade in global market. To gain global competition in product-convergent markets, China’s over 200 thousands cross-border E-commerce businesses have focused more on the service and cost control of supply chain downstream. In this study, we analyse three strategic cost control measures, summarise ten evaluation criteria for cost and de...

Developing an innovative protective structure with excellent energy absorption performance is a continuous research effort. The emerging additive manufacturing techniques allow fabricating structures complex geometrical shapes which have the potential to yield unprecedented properties. Accordingly, in this paper, crush and behaviour of new designs, namely Concave Tubes (CTs) featuring inwardly ...

Choosing the right delivery service partner is an important thing for companies to consider. This because selection of can minimize risks involved. Generally, choosing a done by looking at profile freight forwarder's partner. It takes time determine study aims apply Complex Proportional Assessment (COPRAS) and Rank Order Centroid (ROC) methods in decision support system selecting partners make ...
