Development of a new multi-criteria decision-making method

Abstract

Choosing the best option out of the many available options is always the goal to be achieved in all areas. However, the parameters (criteria) in each alternative are not the same, sometimes contradictory. In this situation, choosing the best option is an extremely difficult decision for the decision maker. Multi-criteria decision making (MCDM) is the ranking of alternatives based on the criteria of each alternative. More than one hundred multi-criteria decision-making methods have been proposed by the inventors. They are being used in many different fields. However, for decision makers, choosing an appropriate method to use in each specific case is a difficult task. CURLI (Collaborative Unbiased Rank List Integration) is a multi-criteria decision making method that distinguishes it from all others. That difference is reflected in the fact that when applying this method, the decision maker does not need to normalize the data nor determine the weights for the criteria. However, it will take a long time for decision makers to apply this method, especially when the number of options to rank is large. This study carried out the development of a new MCDM method based on the CURLI method. This new method is named CURLI-2. Many different examples are presented to evaluate the effectiveness of the proposed method. In each example, the result of ranking the alternatives using the CURLI-2 method has been compared with those using other different MCDM methods. The best alternative determined when using the CURLI-2 method always coincides with the use of existing MCDM methods. Using CURLI-2 method to rank alternatives will be much faster and simpler than using CURLI method. This is the advantage of CURLI-2 method compared with CURLI method

Selecting lubricating oil for two-stroke gasoline engines: a multi-criteria decision-making approach

“…As a result, the COCOSO method consistently identifies L3 as the best solution, regardless of the criteria weights used, underscoring the method's effectiveness and robustness [14]. The ranking results for lubricant types may differ when using different weighting methods, a phenomenon also discussed in numerous pre vious documents [17][18][19]. A limitation of this method is its lack of consideration for environmental factors in the use or recycling of lubricating oils.…”

Áp dụng phương pháp CURLI để lựa chọn vật liệu chế tạo bánh răng

“…Chính vì vậy kết quả xếp hạng các phương án không phụ thuộc vào suy nghĩ chủ quan của người ra quyết định [13]. Gần đây, phương pháp này đã được sử dụng nhiều để xếp hạng các phương án trong nhiều lĩnh vực khác nhau, như xếp hạng các phương án của một quá trình mài [14], xếp hạng các phương án của một quá trình tiện [15], xếp hạng các loại vật liệu để chế tạo tấm bảo vệ trên ô tô [16,17], xếp hạng các loại dầu cắt gọt [18], lựa chọn đá mài và lựa chọn nhà cung cấp [19]. Tuy nhiên, cho đến nay chưa thấy phương pháp này được áp dụng để xếp hạng các loại vật liệu chế tạo bánh răng.…”

The Multi-Criteria Decision-Making Method: Selection of Support Equipment for Classroom Instructors

“…Notable instances include its utilization in determining a company's financial structure [7][8][9], the selection of chemical production processes [10], and the choice of mechanical processing techniques [11]. Recently, the CURLI method has seen extensive application in ranking alternatives within material in mechanical processing [12], and the selection of grinding stones and suppliers [13]. The burgeoning interest from the scientific community in these two methods has also captured the attention of the authors of this article.…”
