background: sulfur compounds must be removed from petroleum because they contribute to environmental pollution. a strong alkaline solution such as caustic soda is used to remove these compounds. this spent caustic has high values for chemical oxygen demand (cod) concentration, ph and total sulfur. in this study, the regeneration and treatment methodology of sulfidic spent caustic was investigat...

Often it is appropriate to have more than one decision maker perform the pairwise comparisons that are part of the Analytic Hierarchy Process (AHP). With group judgments one would hope for broad consensus among the decision makers, in which case one would aggregate judgments via their geometric mean. However, consensus may not always be reached and significant dispersion may exist among the jud...

This paper develops the spectral properties of pairwise comparison matrices (PCM) used in the multicriteria decision making method called analytic hierarchy process (AHP). Perturbed PCMs are introduced which may result in a reversal of the rank order of the decision alternatives. The analysis utilizes matrix theory to derive the principal eigenvector components of perturbed PCMs in explicit for...

In this paper we combine Real Options (ROs), Analytic Hierarchy Process (AHP) and zero-one Goal Programming (ZOGP) in an integrated decision analysis framework for valuing and prioritizing a portfolio of ICT infrastructure investments. It is the first time that ROs are integrated with AHP and ZOGP providing a single multi-objective multi-criteria model, called GROAHP. Finally, a case illustrati...

Analytic Hierarchy Process (AHP) is very popular method in the field of decision-making today. While one of the most natural extensions of AHP using fuzzy theory is to employ a reciprocal matrix with fuzzy-valued entries, some of the present authors proposed the fuzzy constraint-based approach before. In this paper, we consider about weights for fuzzy constraint-based approach and propose a kin...

In this paper we describe a new approach that uses multicriteria decision making and the analytic hierarchy process (AHP) for integrating privacy and safety criteria into planning tasks. We apply the approach to the journey planning using two criteria: (i) a willingness-toshare-data (WSD) metric to control data disclosure, and (ii) the number of unsatisfied safety preferences (USP) metric to mi...

In many industrial engineering applications the final decision is based on the evaluation of a number of alternatives in terms of a number of criteria. This problem may become a very difficult one when the criteria are expressed in different units or the pertinent data are difficult to be quantified. The Analytic Hierarchy Process (AHP) is an effective approach in dealing with this kind of deci...

DEAHP as a weight derivation procedure for analytic hierarchy process (AHP) has been found suffering from some significant drawbacks. Recently, Mirhedayatian and Saen (2011) [5] proposed a new procedure entitled Revised DEAHP for AHP weight derivation [S.M. Mirhedayatian, R.F. Saen, A new approach for weight derivation using data envelopment analysis in the analytic hierarchy process, Journal o...

This paper attempts to find out the best available alternative material handling system (MHS), an integral component of warehouse operations. Analytic Hierarchy Process (AHP), a flexible decision making tool for complex, multi-criteria problems and useful to provide management weightage, has been used in this study to develop performance model. The proposed algorithm, used to select the proper ...

For ranking alternatives based on pairwise comparisons, current analytic hierarchy process (AHP) methods are difficult to use to generate useful information to assist decision makers in specifying their preferences. This study proposes a novel method incorporating fuzzy preferences and range reduction techniques. Modified from the concept of data envelopment analysis (DEA), the proposed approac...
