Supplier Evaluation And An Application At A Manufacturing Firm

Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2004Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 2004Günümüzün yeni, küresel iş dünyasında, şirketler dış kaynak kullanım seviyelerini arttırmışlar ve rekabette avantaj sağlama kaynağı olarak tedarik zincirlerine daha fazla önem vermeye başlamışlardır. Dolayısıyla, tedarik zincirine hangi tedarikçilerin dahil edileceği stratejik bir karar haline gelmiştir. Bu tezin amacı satınalma karar vericilerine tedarikçi değerlendirme için bir araç sağlamak üzere güncel üretim gerekliliklerini de özel olarak vurgulayarak, ağırlıklı bir puanlama yöntemi geliştirmektir. Ağırlıklandırma yöntemi kriterlere ağırlıklar atayarak ve kriterleri derecelendirerek en iyi tedarikçinin değerlendirilmesini ve seçimini sağlar. Bu tezde geliştirilen ağırlıklandırma modeli 5 tane kriter ve 16 tane alt kriterden oluşmaktadır. Daha sonra bu genel amaçlı model, Lüleburgaz ve Ankara’da iki fabrika ile operasyonlarını sürdüren lider sütlü ürünler üreticisi Danonesa’ya uygulanmıştır. Modelin uygulanabilirliği geliştirme sürecinin başından itibaren dikkate alınmış ve model Danonesa’nın ilgili yöneticilerinin önerileri ile tamamlanmıştır. Model belirli türlerdeki ambalaj tedarikçilerine uygulanmıştır. Plastik kap ve kapak tedarikçileri ile alüminyum folyo tedarikçileri araştırmaya dahil edilmiştir. Hangi kriterlerin modele dahil edileceğine, literatür araştırmasının neticesinde veya Danonesa’nın satınalma yetkililerinin önerileri ile karar verilmiştir. Çalışmanın sonunda seçilen malzeme grupları için tedarikçilerin performanslarının ölçümü ile ulaşılan sonuçlar gösterilmiştir.In the new global business environment, companies have increased their level of out-sourcing and they are relying more heavily on their supply chain as a source of their competitive advantage. Thus, determining which suppliers to include in the supply chain has become a strategic consideration. The aim of this thesis is to design a weighting point method to provide the purchasing decision makers a tool for evaluating suppliers with a special emphasis on current manufacturing challenges. The weighting model provides evaluating and selecting the best supplier by assigning weights to the criteria and rating the criteria. The weighting model developed in this thesis is consisted of 5 criteria and 16 subcriteria. The general-purpose model is then applied to the leading dairy products manufacturer Danonesa, which operates with two plants at Lüleburgaz and Ankara. The applicability of the model is taken into consideration from the beginning of the development process and the model is finalized with the suggestions of the related managers of Danonesa. The model is applied to the suppliers of certain types of packaging materials. Plastic container and cover suppliers and aluminium foil suppliers are included in the research. Which criteria to include in the model is decided either as a result of the literature search or by the suggestions of the authorized purchasing personnel of Danonesa.The results obtained by measuring the performance of the suppliers for the selected material groups are represented at the end of the study.Yüksek LisansM.Sc

The Impact of Financial Inclusion on Economic Growth and Income Inequality

Financial inclusion is defined as the access of households and firms to beneficial and reasonably priced financial products and services which are in line with their necessities. These could be financial transactions, transfers, savings, and loans. After narrowing down the definition, it then measures financial inclusion by using indexation technique. A major contribution of this study is the development of a measure of financial inclusion via formation of three indices, namely financial access index, firm-level and household-level financial usage indices. These three indices capture different aspects of financial inclusion, which is comprised of access to financial services by both households and firms in addition to effective use of these services. Based on Global Findex database and the Enterprise Survey database collected by the World Bank, Financial Access database collected by the International Monetary Fund the study introduces measures of household-level and firm-level inclusion, with placing Europe and Central Asia in a historical and cross-country perspective. By using Panel and Ordinary Least Squares regression analysis, it analyzes the impact of financial inclusion on two important macroeconomic variables, namely growth and inequality. Moreover, it focuses particularly on the ECA region and analyzes the dynamics in the region. The study aims at documenting the status of financial inclusion in ECA, while shedding light on the impact of financial inclusion on growth and inequality. It concludes that, in line with the contemporary literature, financial inclusion enhances growth and reduces inequality with better access to resources to finance both consumption and investment. According to the article’s findings, the positive impact of financial inclusion on growth is significant in the ECA region.

Induced current magnetic resonance-electrical impedance tomography

Magnetic resonance-electrical impedance tomography (MR-EIT) is a conductivity imaging method based on injecting currents into the object. In this study, a new MR-EIT method, whereby currents are induced inside the object by using external coils, is proposed. This new method is called induced current magnetic resonance-electrical impedance tomography. In induced current MR-EIT surface electrodes are not used and thereby artifacts due to electrodes are eliminated. The reconstruction algorithm is based on the measurement of only one component of the secondary magnetic flux density. The algorithm is an iterative one, is 3D and is based on the solution of a linear matrix equation at each iteration. For the measurement of secondary magnetic flux density, a pulse sequence to be used in the MRI system is proposed. Numerical simulations are performed to test the algorithm for both noise-free and noisy cases. The singular value behavior of the matrix is monitored and it is observed that at least two current induction profiles improve the images significantly. It is shown that induced current MR-EIT can be used to reconstruct absolute conductivity images without the need for any additional peripheral voltage measurement. © 2005 IOP Publishing Ltd

Türk iş hukukunda işe alım ve iş sözleşmesinin kurulması

Anahtar Kelimeler: İşe Alım, İş Sözleşmesinin KurulmasıÖZETTÜRK İŞ HUKUKUNDA İŞE ALIM VE İŞ SÖZLEŞMESİNİN KURULMASIGünümüzde teknolojik gelişmeler, her alanı olduğu gibi işe alım sürecini de değiştirmektedir. İşçi ve işveren arasındaki iş ilişkisinin başlangıcı olan işe alım sürecinde farklı yöntemler örneğin sosyal medyanın kullanımı yaygınlaşmaktadır. Hangi şekilde olursa olsun, işe alım ve iş sözleşmesinin kurulmasına dair taraflar çeşitli hak ve yükümlülüklere tabi olup, özellikle işverenin sözleşme serbestisi sosyal düşünceler ile kısıtlanmıştır. Ancak bu konudaki yasal yükümlülükler, hukukumuzda genel olarak yeterli yaptırıma tabi kılınmadığından, etkin şekilde uygulanabilirliği söz konusu değildir. Bu nedenle, bu yönde çeşitli yasa değişiklikleri yapılmalıdır. Yasama faaliyetlerinin sosyal tarafların ve akademisyenlerin de görüşleri alınarak, daha şeffaf ve işbirlikçi yöntem ile yapılması ise, hedeflenen amaca ulaşmak için daha etkili olacaktır.Anahtar Kelimeler: Recruitment , Establishment of Employment ContractABSTRACTRECRUITMENT AND ESTABLISHMENT OF EMPLOYMENT CONTRACT IN TURKISH LAWTechnological developments transform recruitment as well as other subjects. Different methods such as use of social media has spread as a new way of recruitment, which is the beginning of the relationship between an employee and an employer. No matter what method is used, parties are required to obey some rules during recruitment and establishment of the employment contracts. Especially the employer's freedom of establishing employment contract is limited with social thougths. However, legal obligations in this respects have very limited enforceability by reason of weak sanctions in Turkish Law. Therefore, those rules have to be amended. In order to be effective, legislation process should involve the social partners and academy and it should also be more transparent and have a cooperative spirit
