This study develops a procedure for performing multi-attribute decision-making ship structural design of multi-purpose ship. The already designed is further structurally to comply with the requirements Classification Societies. hull and components are verified against yielding, buckling, ultimate strength. Based on limit state (ULS), first order reliability method (FORM) employed analyse risk i...

This paper is devoted to present Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method for multi-attribute group decision making under rough neutrosophic environment. The concept of rough neutrosophic set is a powerful mathematical tool to deal with uncertainty, indeterminacy and inconsistency. In this paper, a new approach for multi-attribute group decision making prob...

during recent years, determining appropriate strategy in the supply chain has become an important strategic issue. however, the nature of these decisions usually is complex and unstructured. to determine the best supply chain strategy, many quantitative and qualitative attributes such as cost, responsiveness and flexibility can be taken into account. in order to approximate the human subjective...

in some multi-attribute decision making (madm) problems, various relationships among the decision attributes should be considered. this paper investigates the prioritization relationship of attributes in madm with trapezoidal intuitionistic fuzzy numbers (trifns). trifns are a special intuitionistic fuzzy set on a real number set and have the better capability to model ill-known quantities. fir...

Spherical fuzzy set (SFS) is also one of the fundamental concepts for address more uncertainties in decision problems than existing structures sets, and thus its implementation was substantial. The well-known sine trigonometric function maintains periodicity symmetry origin nature satisfies expectations experts over multi parameters. Taking this feature significance SFSs into consideration, mai...
