Sand and gravel are important raw materials which are needed for many civil engineering projects. Due to economic reasons, sand and gravel pits are frequently located in the periphery of metropolitan areas which are often subject to competing land-use interests. As a contribution to land-use conflict solving, the Analytic Hierarchy Process (AHP) is applied within a Geo-Information-System (GIS) ...

Many researchers have long observed some cases in which certain ranking irregularities can occur when the original analytic hierarchy process (AHP), or some of its variants, are used. This paper presents two new categories of ranking irregularities which defy common intuition. These ranking irregularities occur when one decomposes a decision problem into a set of smaller problems each defined o...

In real life, sometimes Multi-Criteria Decision Making (MCDM) problems are dealt with inevitably under the disturbance of subjective factors such as intuition, feeling and emotion. However, the existing work cannot handle the issue well. As a result, it is difficult for them to predict and give some decision support for MCDM problem of this kind. Thus, to address the issue, this paper construct...

‎in this paper, we present a two-stage model for ranking of decision making units (dmus) using interval analytic hierarchy process (ahp). since the efficiency score of unity is assigned to the efficient units, we evaluate the efficiency of each dmu by basic dea models and calculate the weights of the criteria using proposed model. in the first stage, the proposed model evaluates decision making...

In parallel to computer technology drastically developing, various simulation software packages focusing on solving different kinds of engineering problems have been introduced to the world market. As the result of this, the selection of proper simulation software has been of considerable importance to any simulation analyst in a simulation project. On the other hand, the best satisfying simula...

This study aims to evaluate the hazards of stainless tank production process in a company by using Integrated Analytic Hierarchy Process (AHP) and Failure Mode Effect Analysis (FMEA) methods. First, were identified. Identified assessed with FMEA method calculate Risk Priority Number (RPN) for each hazard. The same then weighted AHP method. Finally, are integrated achieve more objective result t...

Based on features of distance education and its disadvantages in terms of learning evaluation, this study uses Analytic Hierarchy Process (AHP) and fuzzy mathematics theory to study distance education. First, an electric file is generated for each learner. Then a practical multi-hierarchy evaluation model is built based on AHP. Finally, evaluation of on-line education is done based on informati...

In this paper the authors review the developments of the Analytic Hierarchy Process (AHP) since its inception. The focus of this paper is a neutral review on the methodological developments rather than reporting its applications that have appeared since its introduction. In particular, we discuss problem modelling, pair-wise comparisons, judgement scales, derivation methods, consistency indices...

abstract financial and electronic debts are one of the important issues in iran's financial scope that are considered by economists due to their role in creating financial instabilities. therefore, a model was represented in this survey to evaluate and rank financial and electronic debts in iran including foreign debts, governmental debts, non-governmental debts and banking debts during th...
