This paper investigates the joint scaling and placement problem of network services made up virtual functions (VNFs) that can be provided inside a cluster managing multiple points presence (PoPs). Aiming at increasing VNF service satisfaction rates minimizing deployment cost, we use both transport cloud-aware as well multi-attribute decision making (MADM) algorithms for cluster. The original is...

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...

the rapid pace of changing technology is leading to high rate of import and export between different countries. in outsourcing governmental organizations duties to private sectors, it is a need to control sectors and they should be under assessment policy. this research has been developed to show how the accredited laboratories of iranian standard (isiri) can be assessed for their technical ser...

Aggregation operators perform a valuable and significant role in various decision-making processes. Averaging geometric aggregation are both used for capturing the interrelationships of aggregated preferences, even if preferences independent. The purpose this paper is to analyze theory complex linguistic fuzzy (CLF) sets their important laws, such as algebraic score values, accuracy describe re...

This paper presents a new method for multiple person multiple attribute decision making (MADM) based on decision makers' subjective preference information on alternatives and objective decision matrix. In this method, multiple decision makers give their preference information on the alternatives in different formats, and an optimization model is constructed to reflect both decision makers' subj...

The effect of cutting tool insert geometry has significant role for surface finish in turning operation. There are many different types of tool inserts with different tool insert geometry are used in turning operation. This paper present a logical procedure to select best tool insert from alternative tool inserts for better surface finish in turning operation. The procedure based on three well ...

With respect to multiple attribute decision making (MADM) problems in which the attribute values take the form of hesitant fuzzy elements, the traditional grey relational projection (GRP) method is extended to solve multiple attribute decision making problems under hesitant fuzzy environment. Based on the hesitant fuzzy decision matrix provided by decision makers, all feasible alternatives are ...
