– AbstractIn a heterogeneous wireless network, multiple networks are available to provide end to end mobility and service to mobile users. So in heterogeneous wireless network, selection of the optimal network becomes an important task, which is a key technology to realize fair resource allocation and load balancing for converged multi-radio heterogeneous networks. In this paper, we combine the...

In pavement management, prioritized resource allocation is imperative given the fact that there is rarely enough funding with highway agencies to address all the pavement sections. In view of the complexity involved in the decision making process, subjective evaluation based on expert’s judgments is unavoidable. Analytic Hierarchy process (AHP) has been applied by researchers to solve pavement ...

The hierarchical TOPSIS model used in this article is able to grasp the ambiguity exists in the utilized information and the fuzziness appears in the human judgments and preferences. The use of the hierarchical fuzzy TOPSIS methodology offers a number of benefits: (1) being a systematic model and straight forward one for working on; and (2) capable of capturing human's appraisal of ambiguity wh...

Energy is a critical factor to obtain a sustainable development for countries and governments. Selection of the most appropriate energy alternative is a completely critical and a complex decision making problem. In this paper, an integrated multi-criteria decision-making (MCDM) methodology based on type-2 fuzzy sets is proposed for selection among energy alternatives. Then a roadmap has been cr...

In commercial software system development, software vendors often face the many difficulties to deal with large amount of requirements that enter the company every day. It is not possible to satisfy all the requirements in given constraint like time, cost, etc. hence there is a need to select the requirements that are more important. Requirements prioritization is a way that can play important ...

The aim of this study is to formulate an analysis model which can express the security grades of software vulnerability and serve as a basis for evaluating danger level of information program or filtering hazardous weaknesses of the system and improve it to counter the threat of different danger factors. Through the utilization of fuzzy analytic hierarchy process (FAHP), we will organize the cr...

Iranshahr Basin is located in the Sistan and Baluchistan province, subject to severe drought excessive groundwater utilization. Over-reliance on resources this area has led aquifer drawdowns socio-economic problems. The present study aimed identify appropriate sites for Artificial Recharge Groundwater (ARG) a single platform by applying GIS fuzzy logic spatial modeling. Three stages were perfor...

The objective of the present paper is to develop a systematic and sustainability-focused evaluation framework determine best locations for wind plants in Vietnam. For decision-making that influences plant site selection, while some criteria can be evaluated based on numerical database, numerous qualitative must under experts’ judgments form linguistic terms represented through fuzzy numbers. In...

Seawater desalination plants have been utilized to supply fresh water to the State of Kuwait since the early 50’s. In spite of the fact that there are several types of desalination technology that can be used more efficiently and economically, one type of desalination technology, namely multi-stage flash (MSF), has been used extensively in Kuwait. This work is an attempt to identify the most su...
