Abstract

Software risk management refers to systematic process for analyzing and identifying the project risks. The present paper provides a hybrid method for IT software risks identification. Software projects possess different features which increase the project failure possibilities. Therefore, the present work integrate the Artificial Neural network with the Analytic Hierarchy Process (AHP-ANN) in order to solve the problem of software project estimation in early stage. The questionnaire developed to find out the risk functional model and provide the proposed method with proper data. The results observe a major common risk in software projects is the insufficient knowledge based on different software project life cycle stages. Also, there are some other important factors in software projects such as lack of good estimation in project scheduling, poor definition of project requirements which cause human errors.

Abstract

Baghdad City suffers from severe traffic congestion due to the rapid urban expansion and traveldemand growth. Based on many studies, urban rail transit was proposed by experts and the related transitagencies as an optimal solution to solve this problem. Accordingly, Baghdad metro route selection based onmulti-criteria was proposed to be studied, evaluated and searched in the present research. The methodologyutilizes a GIS to prepare and analysis data. Data was analyzed using a two-stage multiple-criteria decisionmaking (MCDM) model which includes Analytical Hierarchal Process (AHP) and TOPSIS methods. Moreover,Geographic Information System (GIS) was used to explore the various route alternatives. To select the bestalternative, all alternatives were evaluated against the selected criteria. The weighting system is not only basedon expert’s opinions but also includes a set of measures based on real data. Based to the outcomes of the presentstudy, alternative route number 1 can be recognized to be the optimal route in the year 2014, and alternativeroute 2 is recommended to be adopted to meet the high travel demand requirement in the year 2035.

Abstract

Groundwater is an important resource in Halabja Said Sadiq sab-basin, Sulaymaniyah district for agricultural and other uses. Continuous dramatic extraction of groundwater from legal and illegal wells led to a severe decline in the water table for the last thirty years. The objectives of this study are to delineate the groundwater productivity zones by combining the geographic information system and geoelectrical survey, which serves to recognize the locations of good groundwater storage and recharge zones. The Halabja Said Sadiq sub-basin has been selected as a case study to delineate the groundwater productivity zones. Four geoelectrical resistivity profiles conducted with electrode spacing 10 m and the length of the profiles is equal to 710 m. Themes such as hydrogeology, land use/land cover, topography, drainage density, soil type, slope, lineaments and rainfall maps are created. The thematic maps made with GIS platform and appropriate weights put to the attributes taking into account the influence on the storage potential of groundwater. The results of geoelectrical profiles revealed that the aquifer thickness is 150 m. Three zones of groundwater potential delineated which are low, moderate and high and cover 33 %, 24 %, and 42 % of the total area respectively. Spatially, the highest zone is located along with the Quaternary deposits which characterized by high lineament density, low slop, and pediment deposition The output of the groundwater potential model is verified by testing the discharge rate of the existing 580 wells. The results are revealed that most of the high yield wells are located within the high groundwater potential zone. Results of such verifications proved that the groundwater productivity areas recognized by GIS (AHP) and geoelectrical techniques are dependable and practical.

Abstract

Groundwater is an essential source of fresh water in the semiarid areas and it contributes to the water supply for several purposes. Bazian basin has become an attractive area for the large companies to invest especially the cement and Iron factories. Hence there is an intensive withdrawal of groundwater. The objectives of this work are to categorize and delineation the productivity areas with the aid of remote sensing and geographic information system methodologies. The Analytica hierarchy process AHP method is used for mapping of groundwater potential zones which the most broadly used Multiple criteria decision analysis (MCDA) models. Six thematic layers are introduced to the GIS platform which area soil, drainage density, land useland cover, geology, geomorphology, slope. Based on the relative effect of controlling groundwater productivity the input layers were ranked. Each factor is classified into classes based on hydrogeological properties. The importance of each thematic layer and its weight is discussed for the location groundwater potential zones using groundwater conditions. The results revealed three productivity areas, low, moderate, and high and they cover 20.14%, 38.5%, and 41.4% of the total area respectively. Besides, the northeast and southwest parts of the basin characterized by low groundwater potential while the moderate zone of the potential area covers the central and some part of the west of the area of interest. The model is validated by testing the available discharge of 78 wells, and it showed that most of the high yield wells are located inside the high groundwater potential zone. The validation results are verified that the groundwater productivity areas recognized by the GIS (AHP) method are reliable and practical.

Abstract

The study area is located SE of Darbandikhan town, which is about 158 km far from the Sulaymaniyah city. In the present study, Analytic Hierarchy Process (AHP) based model and multiple parameter analysis are applied to identify forest fire risk zones in Sartak watershed using Geographic Information System (GIS) and Remote Sensing (RS) techniques. Satellite images are used to generate vegetation, roads, settlements and farmland maps. Slope gradient, slope aspect and elevation maps are derived from Digital Elevation Model (DEM). Whereas, the Tropical Rainfall Measuring Mission (TRMM) data is used to build up mean annual rainfall map of the study area. Forest fire risk zone map was delineated from the scored and weighted layers of all influencing factors on forest fire (vegetation, slope gradient, slope aspect, altitude, rainfall, distances from settlements, roads, international border and farmlands). As a consequence, the study area is classified into five forest fire risk classes. 16.16% of the total area falls in the category of very high risk, followed by 25.37%, 24.51%, 19.01%, and 14.95% in the categories high, moderate, low and very low, respectively. The results help and enable the institutions concerned with forests to set up appropriate fire-fighting infrastructure for the areas more prone to fire damage and exploit the geological and geomorphical situation of the study area to build a natural protection area.

Abstract

Materials selection is a multi-criteria decision-making (MCDM) problems because the large numberof factors affecting on decision making. The best choice of available material is critical to thecompetitiveness and success of the manufacturing organisation. The analytical hierarchy process(AHP) is an important tool to solve MCDM problems. The choosing process of suitable material(such as a refrigerant fluid) for the Air Condition System (ACS) is faced with challenges such aslack of a systematic approach in setting the optimal performance in terms of its impact on theenvironment and operation. Selecting process for the one refrigerant from a range suitable ofsuitable refrigerant is complex process. The study presents a comparative performance analysisof ACS for using four alternative refrigerants R290, R410, R404 and R22. Then, one of these suitablerefrigerant is selected. The comparison is based on three criteria system operation, environmentand maintenance.Novels ACS performance assessment model is proposed based on an analytical hierarchy process(AHP). The model is based on two main criteria of ACS, quantitative criteria, cooling capacity(CC), coefficient of performance (COP), etc.).And qualitative criteria (Ozone Depletion Potential (ODP), Global Warming Potential (GWP) andmaintenance cost (MC)). It is necessary to look for new technique help decision making to selectalternative refrigerants, to fulfill the goals of the international protocols (Montreal and Kyoto)and optimum operation, to satisfy the growing worldwide demand, in addition the increase outdoortemperature in some countries.This study provides a developed methodology for evaluating ACS performance. Moreover, it helpsto select a robust decision. The results obtained from AHP process that the best rank of the suitablerefrigerant was R404 (0.3763) followed by R22 (0.3657) and so on for the other. Therefore,the proposed methodology can help the decision maker to select the best alternative for bothcriteria (qualitative and quantitative) in complex selecting process.
