Selection of an appropriate acid type for the recovery of zinc from a flotation tailing by the analytic hierarchy process

The selection of acid type for metal dissolution from minerals is an important issue in leaching operations. Acids are used to recover valuable elements from the minerals by dissolving them in a solution. The acid must offer a high recovery at marginal cost and a low environmental effect. Many parameters can affect the acid type selection for high leaching recovery and low environmental effect and thus, the selection of an acid type is complex. In this study, based on the experimental results obtained from the bench-scale laboratory studies, the selection of acid type for the recovery of zinc from a flotation tailing was investigated using the analytic hierarchy process (AHP). The utilization of AHP was supported by the use of ExpertChoice® 2000 software. The outcomes demonstrated that sulfuric acid is the most desirable acid type with a ranking of 0.541, tracked by citric acid, and oxalic acid with scoring of 0.282 and 0.177, respectively. Furthermore, analyses of sensitivity were performed to examine the influence of the main criteria on the different acid type. It emerged that citric acid can be used when the environmental main criterion ascended from 7.8% to 75.3%.

Applying AHP in Evaluation of Vietnamese Commercial Banks

Bank rankings are one of the ways to rate the bank system and to create competitive advantages, which have emerged as the central issue and considered as one of the most important organizational innovation. This research is objective to explore and to demonstrate utility of Analytic Hierarchy Process (AHP) application in banking for the purpose of proposing suitable model for partners evaluation and selecting banking strategic alliances in Vietnam. The AHP is applied to examine what criteria should be encompassed in evaluating and examining the importance weightings of influential criteria when ranking the bank system. In this study, a short review of literature regarding application AHP in banking decision-making is presented, focusing on partner evaluation criteria and methods to propose model for partner evaluation and selecting strategic banking for the current study. After a long process of calculation based on AHP, I have come up with the final rankings according expert's interview: ACB's percentages have change widely from each sub-criterion; finally it gets 12.98% at the top of the list. Coming very closely downwards are DAB, SeAbank etc., at the bottom of the rankings is SGB at 7.41%. By this paper, author would contribute to the ranking process of the banking system, in general, and the special case of Vietnamese banking a very modern model to apply, then to choose the right alliance for further cooperation, not only for banking system but it can be applied for a lot of industries.

Exploring the utility of Analytic Hierarchy Process (AHP) in ranking livelihood activities for effective and sustainable rural development interventions in developing countries

It is commonly known that most development projects, especially in the global south, tend to achieve unintended results or fail because of lack of due diligence. Project satisfaction and sustainability would only be achieved if consistent with the actual needs of the people intended to benefit. Based on field experiences in the Fantekwa District of Eastern Ghana, this study aims to explore the utility of the Analytic Hierarchy Process (AHP) in prioritizing livelihood activities to aid in effective and sustainable poverty reduction interventions in developing countries. Data from twenty five development stakeholders in the district were used for the assessment. The study demonstrates that with appropriate data, and systematically following all required processes, the AHP approach can effectively show where intervention is most needed. Application of AHP in the current context, the study argues, has the potential to address the issue of wrong development targeting with associated counterproductive and nonstarter outcomes.

Land suitability assessment for urban green space using AHP and GIS: A case study of Ahvaz parks, Iran

Soil is a vital parameter for planting design in urban green spaces especially in adverse climate conditions. In this study, the utilization of analytic hierarchy process (AHP) in surveying land suitability for urban green space from measured criteria like suitability indices, including physical (i.e. clay, silt, sand, bulk density, penetration resistance), chemical (i.e. electrical conductivity, sodium absorption ratio, organic matter, Olsen phosphorus, water soluble potassium and DTPA-extractable of Fe, Zn, Cu, Mn) and heavy metal (i.e. total Ni, Cd and Pb) properties of soil and topography attributes (i.e. slope degree) data were investigated. The subjective value judgment, in light of questionnaire survey was utilized for pair-wise comparison after standard AHP method in a structure of four criteria (suitability indices) alongside related sub-criteria (19 factors). AHP method and GIS techniques were combined to create suitability map. The outcomes demonstrated that less than 8.86% of the all study region has no restriction and 34.54% has extreme restrictions for green space land use. The southern part of the riverside parks had higher suitability, whereas the northern area had lower suitability. The real limiting variables include soil compaction, soil salinity, and Zn deficiency; albeit direct mild accumulations were for lead in Ahvaz riverside parks. This study delineates the efficacy of AHP and weighted overlay model for the soil suitability investigation of green space in the study territory. In light of the outcomes, bulk density and organic matter are the most vital indices of soil in urban green space.

Modeling Personal Excellence Competences for Junior High School Principals Based on AHP Method

The objective of the study is to prioritize training needs for the purpose of enhancing personal excellence (PE) competences among a group of nine junior high school principals in Taiwan. A hierarchical PE map with 16 factors clustered under four dimensions was developed as the research framework for further analysis. The utilization of analytic hierarchy process (AHP) technique for prioritizing perceived importance of PE competences aims to determine contextually specific training interventions for a target group of school leaders. A PE training course coverage is shaped with a focus on enhancing critical PE factors of emotional competence for the target group of school principals. The hierarchical structure of PE and method introduced by the present study would contribute to school leadership development, as well as a scheme for leadership selection and evaluations. Limitations and further explorations based on results of the study are discussed.
