Considering the difficulty and complexity involved in choosing an agricultural aircraft, it is proposed to rank agricultural aircraft based on linguistic evaluations of their qualities. Aiming this, it is used an algorithm based on the Analytical Hierarchy Process (AHP) method and in the Technique of Order of Preference by Similarity to Ideal Solution (TOPSIS). The linguistic parameterization i...

Interval-valued fuzzy sets involve more uncertainties than ordinary fuzzy sets and can be used to capture imprecise or uncertain decision information in fields that require multiple-criteria decision analysis (MCDA). This paper takes the simple additive weighting (SAW) method and the technique for order preference by similarity to an ideal solution (TOPSIS) as the main structure to deal with in...

“Handover” is one of the techniques used to achieve the service continuity in Fourth generation wireless networks (FGWNs). Seamless continuity is the main goal in fourth generation Wireless networks (FGWNs), when a mobile terminal (MT) is in overlapping area for service continuity Handover mechanism are mainly used While moving in the heterogeneous wireless networks continual connection is the ...

introduction spatial planning concepts have become prominent in discussions and strategies that focus on regional and rural development. at the heart of this policy framework is an understanding that competition between regions is one of the primary driving forces influencing social and economic development and hence cohesion. it is also understood that some regions have greater advantages in t...

The present study was conducted to assess the possible risks induced by construction of Gavi Dam in Ilam Province; western part of Iran, using MIKE-11 model and technique for order of preference by similarity to ideal solution. For this purpose, vulnerable zone of the dam site against the flooding risk of Gavi River was calculated for different return periods. The flooding zones were stimulated...

Multiple attribute decision analysis (MADA) problems in the situation of belief group decision making (BGDM) are a special class of decision problems, where the attribute evaluations of each decision maker (DM) are represented by belief functions. In order to solve these special problems, in this paper, TOPSIS (technique for order preference by similarity to ideal solution) model is extended by...
