Accurate assessment of groundwater vulnerability objectively reflects an area’s potential for pollution and provides a reference basis control prevention. The main objective this study was to modify the original DRASTIC model improve consistency results with regard actual conditions area. To optimize objectivity, two additional factors that are influenced by human activities (land use degree ex...

The study proposes a stochastic approach to quantify the uncertainty of groundwater vulnerability (GV) produced by classical index-overlay methods. In analysis, physical-based MODFLOW model has been integrated with DRASTIC method and modified analytical hierarchy process (AHP) technique. Specifically, flow fields from provide parameters depth water associated hydraulic conductivity (K) for meth...

Multicriteria decision analysis (MCDA) involves techniques which relatively recently have received great increase in interest for their capabilities of solving spatial decision problems. One of the most frequently used techniques of MCDA is Analytic Hierarchy Process (AHP). In the AHP, decision-makers make pairwise comparisons between different criteria to obtain values of their relative import...

Aminopolymer functionalization with fluoroalkyl chains and resulting void volume afford 4.1-fold increase in amine efficiency 2.8-fold CO2 capture capacity the fluorinated material.

Abstract Evolving groundwater vulnerability from DRASTIC to modified methods helps choose the most accurate areas that are delicate toward pollution. This study aims modify with land use and water quality index for assessment in Halabja-Khurmal sub-basin, NE/Iraq. The sub-basin is calculated nine hydrogeological parameters by overlay weighting method. As a result, 1.3% of total area has very hi...

Success of an e-business company is strongly associated with the relative quality of its website compared to that of its competitors. The purpose of this study is to propose a multi-attribute e-business website quality evaluation methodology based on a modified fuzzy TOPSIS approach. In the proposed methodology, weights of the evaluation criteria are generated by a fuzzy AHP procedure. In perfo...

In recent years a growing number of companies modified their innovation process. Especially after the recent financial downturn, companies are looking for much more efficient and creative business processes. The aim of the presented paper is to present a decision support tool or in other words a software system for the application of the AHP method to support innovative and strategic process. F...

The inconsistency of judgments in the fuzzy Analytic Hierarchy Process (AHP) is a crucial issue. To make the appropriate decision, the inconsistency in decision maker's (DM) judgments needs to be eliminated or reduced. This paper proposes two mathematical models to deal with inconsistency in Fuzzy AHP. In the first model, the DM's judgments are modified where the preference order of the DM's ju...

This paper proposes a modified software quality evaluation method based on products comparison, judging by user perceived satisfaction in terms of quality. The focused evaluation model is formulated on the bases of the ISO 9126 quality model as a generally accepted standard and ISO 12119 for software package, and of the Analytic Hierarchy Process (AHP) which is appropriate for comparing paired ...
