İki aşamalı tedarik zinciri koordinasyonunun bulanık talep altında analizi

Gülçin CANBULUT

Çalışmada; bir tedarikçi ve bir perakendeciden oluşan iki aşamalı bir tedarik zinciri yapısı talep değişkeninin bulanık parametre olması durumunda incelenmiştir. Tedarik zinciri üyelerinin her birinin farklı hedefleri bulunmakta ve kendi performanslarını optimum yapmayı istemektedirler. Bu sebeple tedarik zinciri üyeleri arasındaki koordinasyonun sağlanması gerekmektedir. Bu koordinasyona göre tedarik zincirleri; merkezi ve merkezkaç tedarik zincirleri olarak değerlendirilmektedir. Çalışmada merkezi ve merkezkaç tedarik zinciri modelleri için talep parametresinin bulanık değişken olması şartıy ...Daha fazlası

Performance Evaluation of a Two-stage Supply Chain Under Fuzzy Environment

Gülçin CANBULUT

In this paper, performance evaluation of a two-stage supply chain which consists of a supplier and a retailer under uncertainty environment is examined. In the literature; many studies have been investigated on supply chain performance analysis in uncertainty environment and demand parameter is an essential data on these analyses. When there is sufficient data about demand, it is easy to construct probability distribution of demand. However, in the absence of enough historical data, it is impossible to construct the probability distribution. The demand parameter is intuitively determined and s ...Daha fazlası

The most livable city selection in Turkey with the grey relational analysis

Erkan KÖSE | Gülçin CANBULUT

Purpose – This study has two main objectives: (1) to expand the application areas of grey system theory and (2) to select the most livable city in Turkey. Design/methodology/approach – Choosing the most livable city is a complex problem that requires many criteria to be considered. It is important to select decision points according to which the criteria selection will be made and to what extent the criteria will affect the evaluation. For this purpose, a questionnaire was prepared to determine the criteria to be used in the assessment. The survey results were evaluated by the factor analysis ...Daha fazlası

Goal programming approach for carrying people with physical disadvantages

Oğuzhan Ahmet ARIK | Erkan KÖSE | Gülçin CANBULUT

Most of today's optimization efforts aim to reduce costs, time or the number of resources used. However, optimization efforts should consider other factors as important as these, such as facilitating the lives of the disabled, elderly and pregnant and helping them in their daily lives. In this study, the Nuh Naci Yazgan (NNY) University (Kayseri/Turkey) personnel transport problems were discussed. The NNY University provides a shuttle service to bring employees to school at the start of the work and to leave them at home after work. In order to shorten the collection / distribution time and th ...Daha fazlası

Yatırım kararlarında bulanık bileşik faiz oranı ile karar sistemi

Gülçin CANBULUT

Faiz düşüncesi insanoğlunun varlığından beri düşünülen konulardan biridir. İnsanlık tarihinin ilk günlerinden beri insanlar; yatırım amacıyla elde bulundurdukları maddi varlıkların değerlenmesini istemişler ve çeşitli şekillerde faiz yöntemlerinden yararlanmışlardır. Günümüzde ekonominin dalgalı bir seyir izlemesi ile birlikte; insanların yatırım için kullanmış oldukları faiz yönteminin de dalgalanmalar göstermesi kaçınılmazdır. Bugünkü faiz oranı ile yapılan yatırımın kullanılacağı dönemdeki faiz oranı arasındaki ciddi belirsizlikler söz konusu olabilmektedir. Bu çalışmada; faiz oranının beli ...Daha fazlası

Analysis of fuzzy supply chain performance based on different buyback contract configurations

Gülçin CANBULUT

In this study, a two-echelon supply chain is analyzed where the supplier sells the products to retailer, who in turn sells the product to end customers. In such an arrangement, the supplier and the retailer aim to increase their profits individually which causes double marginalization. Several studies have been proposed by researches to solve the problem of ‘‘double marginalization’’ and its consequences to supply chain performance. Therefore, contractual agreements as coordination mechanisms were developed to improve the supply chain performance. In the literature, many studies have been cond ...Daha fazlası

Public transportation vehicle selection by the grey relational analysis method

Gülçin CANBULUT | Erkan KÖSE | Oğuzhan Ahmet ARIK

The success of businesses today is largely dependent on their ability to find solutions to complex problems they encounter. Vehicle selection, which requires considering many objective and subjective criteria, is at the top of these problems. The tramway selection problem of a company operating in the public transport sector in Turkey is discussed in this study. The company wants to increase passenger carrying capacity and renew its vehicle fleet. For this purpose, it has to choose from eight alternative vehicles with different superior features. Considering the high costs that may arise from ...Daha fazlası

Handling of revenue sharing contracts within the scope of game theory

Gülçin CANBULUT | Erkan KÖSE | Oğuzhan Ahmet ARIK

One of the most important problems faced in supply chain management is the coordination between supply chain members. Supply chain contracts, such as buyback contract, quantity-flexibility contract, revenue sharing contract, etc., can be used for solving this problem. In revenue sharing contracts, the manufacturer applies a low wholesale price to the retailer and in return shares a portion of the retailer's revenue. In this study, the revenue sharing contracts between the supplier and the retailer are handled as two-person non-constant sum games. There are two players in the game, supplier and ...Daha fazlası

Fuzzy Linear Programming Model For İnverse Multiple Criteria Sorting Problem: An Application İn A Public Transportation Company

Gülçin CANBULUT

Multi-criteria decision making (MCDM) techniques are among the methods used by the decision maker in the decision phase in practice, as in the literature. MCDM problems are grouped as classifications and sorting problems according to the type of inclusion or ranking in existing classes. Inverse multi-criteria sorting problem, a new topic in recent years, is defined as choosing among existing actions in order to improve the status of alternatives. In this study, in order to find out which action plan should be chosen for providing the minimum cost for the improvement of public transportation ve ...Daha fazlası

Investment Decision Support System Using Credibility Analysis With Fuzzy Interest Rate

Gülçin CANBULUT

Today, with a fluctuating course of the economy, it is inevitable that the interest method used by people for investment will also fluctuate. There may be serious inconsistency between the current interest rate and the interest rate at the time of the investment. Therefore, in order to eliminate these inconsistent situation, fuzzy set theory is used and the case where the interest rate parameter is fuzzy variable is examined. In this way, it is provided that the uncertain interest rate is close to the real-life interest rate.
