Study on Geological Disaster Susceptibility in Nanyang and Xiangyang Basin

Nanyang and Xiangyang Basin is located in the east of Qinling Mountains and Daba Mountain, and the west of Dabie Mountain and Tongbai Mountain. Its north is the Funiu Mountain seated at the east end of Qinling Mountain, and the south is the east end of the Daba Mountains. The main geological environment problems in the area include collapse, landslides, ground fissure, high fluorine water, expansive soil etc. On the basis of collecting the data of geological environment in the basin area, the article regards Nanyang and Xiangyang Basin area and its surrounding area as research objects, and then builds the geological environment database of the study area through GIS platform. Based on the analysis of the factors that affect the geological disasters susceptibility in the study area, an evaluation index system of geological disaster susceptibility was established. The paper expounds the process and steps of applying analytic hierarchy process (AHP) to geological disaster susceptibility assessment, and uses this method (AHP) to establish the hierarchical analysis structural model and the judgment matrix of geological disaster susceptibility comprehensive evaluation, so as to determine the influence of geological disasters. The weight of degree factors establishes a mathematical model for the evaluation of susceptibility to catastrophic disasters in geological disasters and comprehensive evaluation of susceptibility to geology in regional geological disasters. Through using the evaluation module developed by MapGIS, the geological disaster susceptibility of the study area can be divided, and there are four zones: highly-prone area, mid-prone areas, low-prone areas, undeveloped area. This article analyzes the causes of geological disaster susceptibility in the study area, and the research results can provide the basis for geological environment management, planning and disaster prevention and reduction in the study area. At the same time, the reliability of the evaluation results is discussed by comparing the evaluation results with actual geological disasters.

GIS Based Landslide Susceptibility Mapping with Application of Analytical Hierarchy Process in District Ghizer, Gilgit Baltistan Pakistan

District Ghizer is a rugged mountainous territory which experiences several landslides each year. There are 16 major landslide areas and 53 villages that are at high risk to hazards. Keeping in view the severity of natural hazards, the present study was designed to generate landslide susceptibility map based on twelve causative factors viz., slope, aspect, elevation, drainage network, Stream Power Index (SPI), Topographic Wetness Index (TWI), lithological units, fault lines, rainfall, road network, land cover and soil texture. Soil texture was determined by particle size analysis and data for other factors were acquired from freely available sources. Analytical Hierarchy Process (AHP) was employed to identify major landslide causative factors in the district Ghizer. Further, a temporal assessment from 1999 till 2015 was generated to assess the impact of land cover change on landslides. It indicated that the barren soil/ exposed rocks and glaciers have reduced while the vegetation and water classes have shown increment. The total area that lies in moderate to very high landslide susceptible zones was 74.38%, while slope is the main landslide causative factor in the district Ghizer. Validation of the susceptibility map showed 88.1% of the landslides in the study area had occurred in the moderate to very high susceptible zones.

Indicators and criteria for assessing ITS services in the context of road traffic safety

Transport telematics systems integrate information technology with telecommunications for the purposes of transport systems. This helps to improve the safety of vehicles and facilities involved in transport tasks. At the same time, the efficiency of using transport infrastructure and means of transport increases. The development and use of specialised IT applications that use data from transport telematics systems helped to create Intelligent Transport Systems (ITS). Currently, in Poland (in Europe and in the world), more and more advanced services offered by Intelligent Transport Systems are being developed and implemented. It is particularly relevant in road transport, especially because Poland’s road safety is insufficient compared to other European countries. The article presents the authors’ proposed indicators and criteria that can be used for assessing ITS services in the context of road safety. The authors conducted analyses to study the application of AHP (Analytic Hierarchy Process), if ITS services were to be used to improve road safety. Then, it will be possible to choose one solution from all the assessed ones.

A set of environmental, economic and social criteria was defined, evaluated and weighted in the context of Saaty’s analytic hierarchies. The best alternatives were obtained after applying Analytic Hierarchy Process (AHP). The model was applied to the central region of Portugal where forest and agriculture are the most representative land uses. Finally, sensitivity analysis of the set of factors and their associated weights was performed to test the robustness of the model. The proposed evaluation model provides a valuable reference for decision makers in establishing a standardized means of selecting the optimal location for new biomass plants.

Flood Risk Management: Case Study on Institutional Models

This paper presents the findings of an interdisciplinary review of possible country level institutional model alternatives for adopting flood risk management in the Republic of Macedonia, by harmonizing the national water management, and other related systems with the requirements of the EU Floods Directive. Based on the application of Analytic Hierarchy Process (AHP) theory, a tailor-made institutional model for integrated risk-based flood management is proposed as a substitute of the current ineffective flood management approaches that are based on purely engineering/design-based standards and ad-hoc interventions to flood events. It discusses the benefits of introducing the model and outlines the key preconditions to its operationalization. Given the similarity of existing flood management systems in the countries of the wider region, these findings can be used for initiating similar improvements in line with the contemporary flood risk management principles.

Livelihood alternatives model for sustainable rangeland management: a review of multi-criteria decision-making techniques

Although a set of appropriate livelihood alternatives has already been developed to approach sustainable rangeland management (SRM), determining an appropriate livelihood model for supporting policy makers still remains to be a challenge. Livelihood alternatives are affected by multiple factors such as livelihood capital, vulnerability contexts as well as policies, institutions and processes which can be identified by stakeholders from different perspectives. Accordingly, determining appropriate livelihood alternatives is a multifaceted challenge that requires multi-criteria decision-making (MCDM) techniques. This paper aims to review MCDM methods that have the potential to be applied in SRM. It discusses how different MCDM techniques can be used and which techniques are well matched to determine appropriate livelihood alternatives. First, it justifies the need for decision support systems followed by an explanation of the most common MCDM techniques. Among them, two techniques, namely analytic hierarchy process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), are found to be the most suitable MCDM in the case of SRM. Furthermore, based on the reviews on different hybrid approaches, AHP–TOPSIS is introduced as a superior approach to select appropriate livelihood alternatives. Accordingly, AHP is introduced to elicit the relative importance of livelihood criteria and TOPSIS is employed to provide a score for livelihood alternatives. As a conclusion, the application of AHP–TOPSIS approach is proposed where many decision criteria, alternatives and stakeholders are involved. Subsequently, a methodological framework to determine a livelihood model is also developed. This study concludes that, as well as recognizing the theory of appropriate livelihood alternatives, the application of MCDM techniques can be further pursued toward devising a workable policy framework for SRM. At the end, we have elaborated future methodological issues to be considered when selecting feasible alternatives to resolve the current challenges in SRM.

Application of analytic hierarchy process in network level pavement maintenance decision-making

This paper proposes an Analytic Hierarchical Process (AHP) theory based method to determine the weight of the decision-making influence factors, considering their relative significance and generating an overall ranking for each road section. A case study on the highway network maintenance priority was conducted to illustrate the proposed procedure. A total of five pavement maintenance decision-making related factors were considered in the study, including pavement performance, pavement structure strength, traffic loads, pavement age and road grade. The weightings of the five factors were quantified through AHP method. Then, the comprehensive ranking index value Ui was determined, which indicated the maintenance priority of a road section in network level decision-making. From the aspect of maintenance cost, the sensitivity analysis results were in accordance with the weightings of different maintenance decision-making factors. The pavement maintenance cost was significantly sensitive to the change of pavement performance. The case study clearly demonstrated the applicability and rationality of the AHP theory based decision-making method and it can be used as a guideline for pavement maintenance agencies.

Application of analytical hierarchy process (AHP) in prioritizing HAZOP analysis for pilot plant

<p>Injuries, accidents or even fatalities while working in pilot plant are reported worldwide. The implementation of process hazards analysis (PHA) in pilot plant is expected to further reduce the risks of accidents. Hazard and operability (HAZOP) analysis is one of the most widely used methods for PHA. Generally, the outcome of HAZOP analysis could results in identifying large number of hazards thus poses a challenge for assessors to take actions in dealing with all the hazards. The common practice in prioritizing the critical hazards is based on assessors’ experience through deductive judgment using rating scale, taking into consideration safety and the associated costs. However the novel operations and process used, unproven or changing technology, and lack of safety information due to developmental stages have led to poor hazards prioritization and difficulty in selecting actions. This paper presents an application of analytical hierarchy process (AHP) in prioritizing HAZOP analysis for pilot plant. Through this approach, the significant hazards identified using HAZOP will be quantitatively weighted and ranked based on their priority along with the appropriate counter measures to be taken. Application of this approach at the high pressure CO2-hydrocarbon absorption system pilot plants as case study showed that the proposed methodology is capable of identifying and ranking the significant hazards in the process following HAZOP analysis. This is particularly useful as a leading indicator to process designers/engineers/researcher in prioritizing their efforts and resources on more significant hazards, hence prevent accidents of the pilot plant.</p><p>Chemical Engineering Research Bulletin 19(2017) 87-95</p>
