As an special intuitionistic fuzzy set defined on the real number set, triangular intuitionistic fuzzy number (TIFN) is a fundamental tool for quantifying an ill-known quantity. In order to model the decision maker's overall preference with mandatory requirements, it is necessary to develop some Bonferroni harmonic mean operators for TIFNs which can be used to effectively intergrate the informa...

The rehabilitation of contaminated sites involves several considerations in terms of environmental, technological and socio-economic aspects. A decision support system becomes therefore necessary in order to manage problem complexity and to define effective rehabilitation interventions. DESYRE (Decision Support sYstem for Rehabilitation of contaminated sites) is a software system which integrat...

Building professional and efficient systems by using user experience became one of the important research activities that focus on the interactions between products, applications, designers, and users. Unfortunately, using user experience faces many problems. One of these problems is how to predict a user experience efficiently to build robust, effective, and flexible applications. To solve thi...

in this paper we enumerate fuzzy subgroups, up to a natural equivalence, of some finite abelian p-groups of rank two where p is any prime number. after obtaining the number of maximal chains of subgroups, we count fuzzy subgroups using inductive arguments. the number of such fuzzy subgroups forms a polynomial in p with pleasing combinatorial coefficients. by exploiting the order, we label the s...

Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis is a popular tool which examines strengths and weaknesses (internal factors) of an organization or industry together with opportunities and threats (external factors) of the marketplace environment. SWOT analysis is the best method to provide the basic outline to take strategic decisions. In this study, we have integrated SWOT ana...

Most of data in Multi-attribute decision making (MADM) problems are changeable rather than constant and stable. Therefore, sensitivity analysis after problem solving can effectively contribute to making accurate decisions. In this paper, we offer a new method for sensitivity analysis in multi-attribute decision making problems in which if the weights of one attribute changes, then we can dete...

The facility location selection, which is one of the important activities in strategic planning for a wide range of private and public companies, is a multi-criteria decision making problem including both quantitative and qualitative criteria. Traditional methods for facility location selection can not be effectively handled because information can not be represented by precise information unde...

Nowadays, the plant location selection has a critical impact on the performance of numerous companies. In this paper, a methodology is presented to solve this problem. The three decision making methods, namely Delphi, AHP and improved VIKOR, are hybridized in order to make the best use of information available based on the decision makers or experts. In this respect, the aim of using Delphi is ...

Abstract Epidemics can bring huge impacts to economic operation and human health, a practical effective emergency decision-making (EDM) method is of great significance reduce all kinds losses slow the spread epidemics. In process EDM, decision information usually uncertain vague, psychological behaviors various perspectives makers (DMs) should be considered. Hence, this paper develops group (GE...
