Abstract:This study aims at providing expertise for preparing public-based flood mapping and estimating flood risks in growing urban areas. To model and predict the magnitude of flood risk areas, an integrated Analytical Hierarchy Process (AHP) and Geographic Information System (GIS) analysis techniques are used for the case of Eldoret Municipality in Kenya. The flood risk vulnerability mapping follows a multi-parametric approach and integrates some of the flooding causative factors such as rainfall distribution, elevation and slope, drainage network and density, land-use/land-cover and soil type. From the vulnerability mapping, urban flood risk index (UFRI) for the case study area, which is determined by the degree of vulnerability and exposure is also derived. The results are validated using flood depth measurements, with a minimum average difference of 0.01 m and a maximum average difference of 0.37 m in depth of observed flooding in the different flood prone areas. Similarly with respect to area extents, a maximum error of not more than 8% was observed in the highly vulnerable flood zones. In addition, the Consistency Ratio which shows an acceptable level of 0.09 was calculated and further validated the strength of the proposed approach.

“…Literatürde, bütünleşik yaklaşımın farklı problemler ve alanlar için kullanımı [Örn. 25,26,27,28] mevcuttur. Bununla beraber, literatürdeki çalışmalar içerisinde, alt yüklenici seçim problemine "Promethee yöntemi" veya "Promethee-AHP bütünleşik yaklaşımı" ile çözüm getiren bir çalışma mevcut değildir.…”

ÖZETBu çalışmada, savunma sanayi sektöründe ARGE çalışmaları gerçekleştiren bir firmanın, yatırımlarında birlikte çalışacağı alt yüklenici firmayı seçim ve değerlendirme problemine çözüm getirilmesi hedeflenmiştir. Alt yüklenicilik, bir işin bir parçasının önceden belirlenen şartlara uygun olarak, özel yeteneklerini ve kaynaklarını kullanarak daha iyi yapabilecek bir başka firmadan transfer edilmesidir. Alt yüklenici seçim probleminde, maliyetin yanı sıra; teknik gereksinimler, deneyim, garanti süresi, teslim zamanı gibi birden çok kriterin dikkate alınması, elde edilecek çözümün gerçekçi ve uygulanabilir olması açısından zaruri öneme sahiptir. Bu çalışmada problemin çözümü, çok kriterli karar verme yöntemlerinden Analitik Hiyerarşi Proses (AHP) ve Promethee II yöntemlerinin bütünleşik kullanımı ile elde edilmiştir. Karar verici için uygun kriter ağırlıkları AHP ile belirlenmiş ve alternatif alt yüklenicilerin en iyiden en kötüye doğru sıralaması Promethee II ile elde edilmiştir. Aynı zamanda seçilen alternatifin her bir kriter bazında değerlendirilmesi yapılarak firmanın alt yüklenici firma için geri besleme yapabileceği bilgiler elde edilmiştir. AHP yöntemi ile elde edilen kriter ağırlıklarındaki değişimin sıralamaya etkilerini araştırmak amacıyla duyarlılık analizi yapılmıştır. Sonuç olarak, bu çalışma ile bir milli savunma bir projesinin gerçekleştirilmesinde ve yürütülmesinde kritik öneme sahip alt yüklenicinin en etkin şekilde seçimi ve değerlendirilmesi yapılmıştır.Anahtar Kelimeler: Alt Yüklenici Seçimi, Promethee, Çok Kriterli Karar Verme (ÇKKV). MULTI CRITERIA SUBCONTRACTOR SELECTION PROBLEM AND ITS SOLUTION FOR A DEFENCE INDUSTRY FIRM ABSTRACTThis study aims to solve the problem of selecting and evaluating a subcontractor firm for a company that performs research and development activities in defense industry. Subcontractoring means that part of the work is transferred from another company that has special skills or resources that allow it to perform tasks clearly specified in better conditions. During the selection process, considering multiple criteria such as technical requirements of the work, experience of the suncontractor firm, warranty conditions, delivery time, as well as costs is crucial to obtain a realistic and implementable solution. In this study, the solution of the problem is gathered by utilizing the integration of Analytical Hierarchy Process (AHP) and Promethee II method which are multi-criteria decision making methods. Decision Maker's criteria weights are determined by AHP. The ranking of alternatives are obtained Promethee II. The evaluation of the selected alternative on the basis of each criterion is utilized which provides feedback to impove the subcontractor firm. Weight Stability Interval Analysis is performed to investigate impacts of the changes in the weights of criteria determined by AHP on the ranking. As a result, this study provides the most efective selection and evaluation of a subcontractor which is critically important for a national defense research & development...

“…Based on this problem, Buckley (1985) developed a fuzzy-AHP model and after this study various developments of fuzzy-AHP methods and applications have been carried out (Chang, 1996;Wang and Yang, 2007). Yager (1978) presented some ideas on the application of fuzzy sets to multiobjective decision making and emphasis on a means of including diverging degrees of importance to different objectives.…”

This paper describes an application of the Saaty's Analytic Hierarchy Process (AHP) and fuzzy set for selecting the best mode of transportation in Lagos State metropolis. Seven transportation alternatives were considered: private car, okada, keke-napep, train, ferry, commercial bus and taxi. These alternative modes of transportation were evaluated with nine decision criteria: low transportation cost, low environmental effect, large capacity, improved safety, high comfort, high accessibility, improved reliability, low number of interchanges required and faster journey time. This method is used in such a way that information from commuters, who were asked to express their opinions in the ranking of decision criteria, was used in hierarchy prioritization of the criteria and expressed in fuzzy numbers with triangular membership functions. The method is applied at two levels: beginning with the finding of fuzzy weights for the decision criteria, followed by finding the fuzzy weights for the alternatives under each of the decision criteria. Fuzzy scores for the alternatives were obtained.
