What Turkey expects from logistics outsourcing ?
Copyright @ 2011 Yasar UniversityThe economies of the world have become increasingly interdependent, and organizations have come under tremendous pressure to maximize productivity and profitability. Creating value through outsourcing has emerged as a popular competitive strategy for firms of all sizes in all types of industries. The aim of this research is to investigate the use of third party logistics in Turkish companies from the users’ perspective to identify the types of logistics services outsourced, problems encountered in outsourcing these services, logistics costs, decision makers in outsourcing logistics activities, and information sources used in the decision-making process. A structured survey was selected as the tool for data collection. The field study involved face-to-face interviews with 204 companies out of top 500 companies ranked in terms of turnover that are registered with industrial associations and chambers of commerce in Turkey. Moreover, a decision support system based on Bayesian Causal Map is proposed for 3PLs in order to assist them in their service proposals for different sectors. This study is a first attempt to reveal and compare the outsourcing perception of the companies in different sectors, to expose the firms’ underlying motives as well as the respective importance of these motives for outsourcing logistics activities in Turkey. The use of Bayesian Causal Map based on the survey results provides an important guide to the 3PL providers to pick a suitable strategy and to prioritize their operational activities in different sectors in such a way to achieve a competitive advantage
Analyzing competitiveness of automotive industry through cumulative belief degrees
Copyright @ 2012 The European Mathematical SocietyThis study aims to analyze the automotive industry from competitiveness perspective using a novel cumulative belief degrees (CBD) approach. For this purpose, a mathematical model based on CBD is proposed to quantify the relations among the variables in a system. This model is used to analyze the Turkish Automotive Industry through scenario analysis.This research is supported by SEDEFED (Federation of Industrial Associations), REF (TÜSİAD Sabanci University Competitiveness Forum), and OSD (Automotive Manufacturers Association

Social sustainability and smart mobility : exploring the relationship
In this article the relationship between two broad concepts will be explored. The first concept is social sustainability, a concept still in discussion. The second concept is smart mobility, a new concept, related to IT- related mobility options and solutions. How social sustainable is smart mobility ? This article offers a clarification of both concepts and of the relationships between the concepts. The conclusion is that whether smart mobility will be social sustainable depends on the route smart mobility will take; only related to cars, and to higher segments of the fleet, or broader in scope and more related to mobility services. Keywords social sustainability; smart mobility; mobility services; equity; accessibility; social cohesio

A stochastic approach to the flow-concentration curve in traffic flow theory
An alternative stochastic model for the fundamental diagram of traffic flow with minimal number of parameters is proposed. The key features of the model lie in its catastrophic potential function as well as the stochastic nature, which makes it possible to describe the main features of the flow-concentration relation. In particular, the inverse-lambda shape as well as the wide scattering of congested traffic data are both reproduced. In our model, the inverse-lambda shape and the associated sudden jump of physical quantities arise due to the existence of two simultaneous stable traffic flow states and the scattering of the data, on the other hand, is attributed to the noise terms introduced in the stochastic differential equations. The model parameters are then calibrated and compared qualitatively with the data. It is shown that both the fundamental diagram and its variance are reasonably reproduced. (C) 2017 The Authors.
