“…Using fuzzy logic, Niksirat (2022) The COPPE-COSENZA model has proved to be an effective tool to support decisionmakers. Cosenza et al (2015) used structured matrices, based on regional potentialities, to organize economic spaces. This model was intended to support an information system that enables a public administrator to formulate suitable policies for choosing an industrial location.…”

Computer trading is currently relatively limited to quantitative trading in paper markets, such as, futures, swaps, and options, ignoring the large volume of physical commodities trading. Numerical algorithms and mathematical methods are frequently applied in the trading of non-physical commodities and stock markets. However, the physical trade of oil does not have a computer program that represents an unquestionable development that includes more complex and subjective factors that traders take into consideration when entering a transaction. Using fuzzy logic, this work proposes a new approach to base a method that can rank oils and the variables, commonly involved in the trading. It uses fuzzy logic to blend objective and subjective factors and brings in two key hierarchical steps to the process. It is shown that this model can also be useful for apprising a decision-making process, improving internal communication, and for the management of physical commodities trading. Here the options of trading are assessed accordingly to its numerical and linguistic judgments, considering even abrupt outcomes. The wide-ranging options, successive filters, and factors evaluation that mirror the technical and expert trading decision making process make it possible for the future application of artificial intelligence (AI) in physical commodities trading.

“…Then, the degree of suitability was determined using fuzzy membership functions to map the most suitable locations for the PV plant (Figure 5). In the COPPE-COSENZA method, when the proposed index is equal to or greater than one, all factors are offered at the level required for the project, which means that the region is suitable for the proposed project, in this case, a solar PV plant (Cosenza et al, 2015).…”

Photovoltaic (PV) energy has become a low-cost, renewable, and environmentally friendly alternative to meet increasing energy demand. Nevertheless, there is still a lack of projects in this field in Brazil. Therefore, this study compares the results of two studies on the optimal site selection of PV in the Brazilian state of Rio de Janeiro. These studies used different methodologies to reach the conclusions and the resulting map. First, the final map of both studies was divided into a grid, and then the results of each cell were weighted for PV site selection. To compare the results using the maps, an intersection of the 10% of the grid cells with the best results from each study was formed. The results showed an 83% similarity between the different Multi-Criteria Decision-Making (MCDM) methods. The other part of the comparison focused on the following rank similarity coefficients: Spearman Correlation Coefficient, WS Coefficient, Spearman Weighted Correlation Coefficient, and Blest Correlation Coefficient. All these coefficients had values greater than 0.9, indicating a high degree of correlation between the results of the studies. Therefore, the two studies have a high degree of similarity and a high potential for installing photovoltaic solar power plants in Rio de Janeiro, especially in its intersection zones.

“…Both approaches have become basic in the economic space study. The materialistic approach was used by native researchers (Grandberg, 2004;Chekmarev, 2001;Biiakov, 2004;Urunov, 2012), and the idealistic approach was used by foreign scientists (Chorley & Haggett, 2013;Cosenza, Doria, & Pessoa, 2015, Perru, 2007.…”
