In this paper, we propose an optimal network selection technique for vertical handover. The proposed technique allows mobile users to select the best access network with seamless manner and to reduce the processing delay. Thus we aim to exploit the minimum of criteria which should be used for network selection. Our optimal network selection technique combines two multi attribute decision making...

In this paper, we investigate the multiple attribute decision making (MADM) problem based on the arithmetic and geometric aggregation operators with hesitant fuzzy linguistic information. Then, motivated by the idea of traditional arithmetic operation, we have developed some aggregation operators for aggregating hesitant fuzzy linguistic information: hesitant fuzzy linguistic weighted average (...

Efficient selection of bids and product offerings is a key requirement in today’s procurement processes. Purchasing managers have to make comprehensible selections among hundreds of alternatives considering several dozens of criteria. Selection problems like this are challenging, because they require the balancing of multiple, often conflicting objectives. Traditional approaches to multi-attrib...

Abstract Picture fuzzy set (PFS) is a direct generalization of the sets (FSs) and intuitionistic (IFSs). The concept PFS suitable to model situations that involve more answers type yes, no, abstain, refuse. In this study, we introduce novel picture (PF) distance measure on basis operation functions membership, non-membership, neutrality, refusal, upper bound function membership two PFSs. We con...

Forthcoming wireless environment is a fusion of numerous networks with diverse technologies deployed by individual operators. In such an environment, innovative network selection methodologies are required not only to provide “always best connected” service to mobile users but also to maximize network operator’s revenue. To fulfill such requirements, multiple attributes from each network are to...

the purpose followed in this study was to utilize the modern model method of spatial multi-attribute decision making (madm) to provide a comprehensive model for priority classification of vulnerable to drought area in the basin of gavkhouni. the main preference of this method over other methods is that in addition to making use of the geographical data the judgment of decision makers is also ma...
