Assessment of third-party logistics provider using multi-criteria decision-making approach based on interval rough numbers

MABAC method for multiple attribute group decision making under q-rung orthopair fuzzy environment

This paper presents a new approach to the treatment of uncertainty and imprecision in multi-criteria decision-making based on interval rough numbers (IRN). The IRN-based approach provides decision-making using only internal knowledge for the data and operational information of a decision-maker. A new normalized weighted geometric Bonferroni mean operator is developed on the basis of the IRN for the aggregation of the IRN (IRNWGBM). Testing of the IRNWGBM operator is performed through the application in a hybrid IR-DEMATEL-COPRAS multi-criteria model which is tested on real case of selection of optimal direction for the creation of a temporary military route. The first part of hybrid model is the IRN DEMATEL model, which provides objective expert evaluation of criteria under the conditions of uncertainty and imprecision. In the second part of the model, the evaluation is carried out using the new interval rough COPRAS technique.

Normalized weighted geometric bonferroni mean operator of interval rough numbers – application in interval rough dematel-copras model

Making a decision in everyday life always comes with uncertainty and responsibility. To reduce the risk to a minumum and in order to make a right decision a person can use methods of multicriteria analysis in combination in fuzzy logic. A married couple, representing decision makers in this case study, have purchased an apartment and it needs to be completely refurbished including outside carpentry. Aim of this study is to select the most suitable manufacturer of PVC carpentry for apartment refurbishing. A total pool of 14 quantitative and qualitative criteria is used as a base for selection of the most suitable of seven available manufacturers. For this case study we will use one of newer methods of multicriteria analysis of fuzzy Evaluation Based on Distance from Average Solution (fuzzy EDAS) method. Having reached the results, an analysis of sensitivity has been conducted showing stability of results where manufacturer number 4 represents an optimal solution in 13 experimental sets out of 14 total.DOI: http://dx.doi.org/10.5755/j01.ee.29.3.16818

This study aims to introduce a series of novel distance measures of an intuitionistic fuzzy set and an extended Multi-attributive Border Approximation Area Comparison method to address multi-criteria group decision-making problems. To aggregate the intuitionistic fuzzy information, we propose two aggregation operators, namely, the intuitionistic fuzzy Dombi generalised $$ \lambda $$-Shapley Choquet arithmetical average operator and intuitionistic fuzzy Dombi generalised $$ \lambda $$-Shapley Choquet geometric average operator. These aggregation operators consider the importance of combinations and correlations among combinations of input arguments. Furthermore, an illustrative example of a human resource management problem is presented to verify the effectiveness of the proposed method, and sensitivity and comparison analyses are conducted to demonstrate the technique’s stability and advancements. Finally, conclusions are drawn.

An extended MABAC method for multi-criteria group decision-making problems based on correlative inputs of intuitionistic fuzzy information

It is necessary for the design of organizational structure of cybersecurity systems or information security systems to meet the basic corporate goals and objectives. Thus, although cyber security is only an element of information security, it is its most important part. For that reason, it is essential for the organizational structure to be constantly perfected. The analysis of strengths, weaknesses, opportunities and threats (SWOT) is a method to formulate the strategy. The SWOT analysis successfully provides the key factors of the problem. In recent years, the multiple criteria decision making (MCDM) has removed some of the deficiencies. However, the nature of these decisions is usually very complex and using crisp data is not suitable. This paper presents a modification of the Saaty-s scale, in which fuzzy numbers have been used for determining weight values of criteria and alternatives. The method described here takes into account the level of uncertainty of the decision maker. After the application of the AHP method in this way, the values of the functions criteria for each considered alternative are obtained. FA'WOT is a hybrid method combining the well-known SWOT analysis and the Fuzzy AHP. This model is used in determining the development strategy for cybersecurity management bodies.
