Transportation that comes into existence from vital activities is natural necessity. The increased competition and the idea of arriving to destination rapidly with a minimum lost revealed the alternative transportation systems. In many stages of the transportation system, decision making tools may be used to get increased benefit. Also innovative technologies like ERP software are important to manage transportation systems effectively. In this study, the most effective ERP software is selected for a firm that services at urban passenger transport sector using two-stage fuzzy decision making technique. In the first stage, after the lack of the software application is determined, the decision of developing the new software by software development department in firm or buying a package program is given. In the second stage, if developing of the new software in firm is selected, the programming language is determined to develop the most effective ERP software application platform using ...

In this paper, the problems of public transportation customers in Istanbul are addressed and their satisfaction levels are evaluated by using customer satisfaction survey and statistical analysis. A novel interval type-2 fuzzy MCDM method is proposed based on TOPSIS and GRA, to evaluate and improve customer satisfaction in Istanbul public transportation. Then, the criteria need to be improved are determined and different improvement suggestions are made for all public transportation firms.

In this study, we have researched about yard crane scheduling in container terminals and prepared a literature review. In container terminals, time loses occure because of the inefficient use of equipments. Yard cranes are equipments those have been using to load container to vessels or to unload containers from vessels and container terminal operations are often bottlenecked by the slow yard crane movements. In order to reduce the completion time of handling containers and the congestion, yard cranes must be scheduled efficiently. We wish that this study will help to have some knowledge about this exponentially growing topic.

ABSTRACT A case study examining the different modes for transportation of freight by a Turkish logistics-service provider company is presented herein. A number of conflicting qualitative and quantitative criteria exist for evaluating alternative modes of transport. Qualitative criteria are often accompanied by ambiguity and vagueness. To cope with ambiguity and vagueness problem, the fuzzy analytic network process (ANP) method has been used. A large number of detailed criteria that interact with each other have been evaluated and synthesized to obtain the most suitable transportation mode. This evaluation has been carried out by a group of decision makers coming from different management levels and functional areas in the sector of logistics and from the service company with intent to provide a more accurate and mutually acceptable solution. Furthermore, the model used here has been validated by comparing the results obtained with the current preferences of the company.

Traditionally, Single Use Devices (SUDs) have been used and discarded, as the name suggests. These SUDs include operating room devices used in areas such as arthroscopy and laparoscopy, devices such as catheters in cardiovascular surgery and in endoscopy, and ...

The study summarizes the tasks of a supply chain's main functional units which are transportation and warehousing. Considering some similarities between holonistic systems and supply chain systems, an integrated framework is constituted via holonistic approach and a linear programming model to maximize profit of not only the overall supply chain but also the individual units is proposed.

In modern societies almost everything (materials, devices, objects, etc.) sooner or later become a waste. And while nature, in constant cycling of matter and energy reuses its waste, man has developed a series of synthetic materials that are difficult to recycle. These synthetic ...
