Actually, a set of ETL software (Extract, Transform and Load) is available to constitute a major investment market. Each ETL uses its own techniques for extracting, transforming and loading data into data warehouse, which makes the task of evaluating ETL software very difficult. However, choosing the right software of ETL is critical to the success or failure of any Business Intelligence projec...

The aim of this study was to provide an analytical tool to evaluate and select the best supplier(s)/vendor(s) in fuzzy environment for Television (TV) manufacturing organization. A hierarchy through which decision makers can bring about a comparison among the suppliers was worked out and software for the same was developed. The methodology for selection was based upon multiple criteria decision...

Our study focuses on environmental risk assessment of a gas power plant in southern Iran. In this research, after investigating the different activities and processes of the power plant, potential harmful factors were initially identified. Afterwards, the identified risk factors were assessed and classified regarding the severity and probability of occurrence, possibility of recycling, and disp...

Identifying influential nodes in complex networks is still an open issue. Although various centralitymeasures have been proposed to address this problem, such as degree, betweenness, and closeness centralities, they all have some limitations. Recently, technique for order performance by similarity to ideal solution (TOPSIS), as a tradeoff between the existing metrics, has beenproposed to rankno...

Combined heat and power (CHP) or cogeneration can play a strategic role in addressing environmental issues and climate change. CHP systems require less fuel than separate heat and power systems in order to produce the same amount of energy saving primary energy, improving the security of the supply. Because less fuel is combusted, greenhouse gas emissions and other air pollutants are reduced. I...

TOPSIS, known as the “Technique for Order of Preference by Similarity to Ideal Solution” (TOPSIS), is one well-known methods solving “multi-criteria decision-making” (MCDM) problems. Many TOPSIS have been developed solve real-life problems using neutrosophic sets. However, no study has method under interval bipolar linguistic environments. Therefore, this aims present a new concept “interval se...

Purpose: The aim of this study is applying a new method for Industrial robotic system selection. Design/methodology/approach: In this paper, the weights of each criterion are calculated using fuzzy Shannon’s Entropy. After that, fuzzy TOPSIS is utilized to rank the alternatives. After that we compare the result of Fuzzy TOPSIS with Fuzzy VIKOR method. Then we select the best Industrial Robotic ...

The aim of this paper is to extend the TOPSIS method for decisionmaking problems with Fuzzy data. By this extension of TOPSIS method, an algorithm for determining the most preferable choice among all possible choices in the case of fuzzy data is presented. To illustrate the performance of the proposed algorithm, a decision-making problem is solved at the end of paper.

Abstract In this article, the selection of weight factor (WF) is improved using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) based cost function (CF) optimization predictive control in surface mounted permanent magnet synchronous motor (PMSM) drive under different conditions. Basically, empirical approach used WF instinctive and consumes excess time. TOPSIS chooses a ...
