Application of Multi-Criteria Decision-Making Methods in the Selection of Cargo Firms

AKARÇAY, Özlem | YAŞAR, Esra | AKGENÇ, Ertan

In recent years, developed technology has provided to facilitate forms of transportation, reduce the costs, introduce new markets and enhance various selection criteria offered by logistics companies. Competitive levels among logistics companies due to intensive customer demands are tend to increase and it has become a necessity to determine the most appropriate cargo firm in order to meet these demands. Moreover, decision- making about cargo firm is a curious issue for companies, since this process includes a hard work- flow. The objective of this study is to solve the problem about selecting ...Daha fazlası

The Impact Of Economic Crises On Consumer Behavior In Konya

GEDİK, Hasan | AFŞAR, Bilge

In 2008, the economic crisis that emerged in the United States has a global dimension, affecting the entire world. The crisis periods which is a war of survival for businesses, influence the owners and employees of businesses and consumers significantly. Varying income levels of consumers bring about changes in needs, priorities and purchasing behavior. To know the consumer behavior in the crisis environment allows companies to take the right decisions about their possible behaviors, preferences and expectations of the product. In this study, the effects of the 2008 economic crisis in 2015, ch ...Daha fazlası

Time and volume-ratio effect on reusable polybenzoxazole nanofiber oil sorption capacity investigated via machine learning

OFLAZ, Kamil | OFLAZ, Zarina | ÖZAYTEKİN, İlkay | BASTUGAN, Rabia

Diesel oil sorption capacities (DOSCs) of polybenzoxazole/polyvinylidenefluoride nanofiber mats with four different groups (-O-, -S-S-, phenylene anddiphenylene) in the main chain structures were investigated. Different experi-mental duration and diesel-oil/tap-water volume ratio pairs were used for dieseloil sorption. No degradation was observed in the nanofiber mat structures afterdiesel oil sorption. The characterizations of polybenzoxazole (PBO) nanofiberswith high diesel oil selectivity were performed by scanning electron microscopy,atomic force microscopy, Fourier transform infrared spec ...Daha fazlası

The Impact Of Paris Agreement on Turkish Coal Power Project Developments

UYANIK, Sırrı | ALTÜRK, Orhan

EuraCoal, a European mining industry lobby group, estimates that Turkey has around 1.3 billion tonnes of hard coal and 11.5 billion tonnes of lignite resources, of which 0.5 billion tonnes and 9.8 billion tonnes respectively are proven reserves. As worldwide populations and industrial growth reach new heights, electricity demand is projected to increase substantially. Fossil fuels, particularly coal, will continue to be a vital energy source for the power sector in many countries. At the same time, fossil fuel fired power generation is one of the largest sources of global CO2 emissions. High-e ...Daha fazlası

Optimal Residential Load Control Comparison Using Linear Programming and Simulated Annealing for Energy Scheduling

GÜLER, Emre | BAŞARAN FİLİK, Ümmühan

Many tariffs are used for electricity pricing. Electricity bills can be reduced by choosing the optimal working hours of appliances and for appropriate tariffs in smart homes. In this study, Linear Programming (LP) and Simulated Annealing (SA) methods are realized and compared each other to find minimum bill. The multi-time tariffs that have different energy unit prices at different times of the day are preferred. Energy Management System (EMS) shifts time slots of some appliances to cheap energy unit prices. Optimal load control is applied to prevent high peak demand because there may be over ...Daha fazlası

Energy Supply Chain and Energy Security

ÖZKAN NESİMİOĞLU, Şerife

Energy Supply Chain and Energy Security Şerife Özkan Nesimioğlu Correspondence: serife.ozkan.nesimioglu@karatay.edu.tr In general, supply chain security is a prominent part of energy security, which is defined as “uninterrupted availability of energy sources at an affordable price” by International Energy Agency (IEA). In more detail, energy security can be separated into two sub-definitions as short and long- term energy security. Short term energy security focuses on the ability of the energy system to react promptly to sudden changes in the supply- demand balance. Here, sudden changes refer ...Daha fazlası

Import Dependency And Seeking For New Energy Technologies European Union Case

ÖZKAN NESİMİOĞLU, Şerife

In this paper, energy poverty and as a result of this energy import dependency and its possible negative results have been examined by taking European Union (EU) into consideration. This analysis has two aims: the first one is questioning the European Unions’ energy security from supply perspective and the second one is investigating the solutions produced by European Union to get away or at least to reduce its energy import dependency. To guarantee its energy supply security at affordable price and to attain its targets about energy security, some action plans has been being put into practice ...Daha fazlası

Biogas Potential Of Ereğli City

TUNÇEZ, Fatma Didem

Turkey's growth and development goals mean that its energy need will increase rapidly in proportion to its growth. Meeting the increasing energy need from fossil fuels such as coal, oil and natural gas causes the depletion of natural resources. Another problem is that the increase in energy demand is increasingly met with imports. The solution of this problem is to diversify the energy supply with renewable energy sources. Biogas is one of the renewable energy sources. Biogas potential of Ereğli District was revealed in this study.

Utilization of Waste for Energy Generation in Clinker Production: Environmental Perspective

TUNÇEZ, Fatma Didem

Meeting the increasing energy need from fossil fuels such as coal, oil and natural gas caused the rapid depletion of natural resources. In a world where the need for energy is constantly increasing and resources are getting scarce, it is necessary to ensure the sustainability of energy. Clinker production is a process which require high amount of energy in manufacturing industry. The fact that energy is mostly obtained from coal, which is a non-renewable fuel, puts the future of the sustainability of cement production at risk. Alternative fuel usage plays the most important role in achieving m ...Daha fazlası

Interval Type-2 Fuzzy Analytic Hierarchy Process Application on Warehouse Performance Measurement Criteria Defined

YAŞAR, Esra | ARAS, Nil

Warehouse performance measurement is of great importance for the development of companies. The companies are to measure their current situation in order to attain ability relating to realizing the improvement process. In this measurement phase, they have to decide what is considered and what proportion it is done. In this study, the most effective factors were determined using the interval type-2 fuzzy analytic hierarchy process method for the factor values that are effective in warehouse performance measurement. The reason to use this solution method is that because of having 3 dimensional me ...Daha fazlası

Publication Preview Source Estimation of disease progression for ischemic heart disease using latent Markov with covariates

OFLAZ, Zarina | YOZGATLIGİL, Ceylan | KESTEL, Sevtap

Contemporaneous monitoring of disease progression, in addition to early diagnosis, is important for the treatment of patients with chronic conditions. Chronic disease‐related factors are not easily tractable, and the existing data sets do not clearly reflect them, making diagnosis difficult. The primary issue is that databases maintained by health care, insurance, or governmental organizations typically do not contain clinical information and instead focus on patient appointments and demographic profiles. Due to the lack of thorough information on potential risk factors for a single patient, i ...Daha fazlası

Kırsal kalkınmada elektronik ticaretin rolü üzerine teorik bir inceleme

TUNCER, İlhamş | GÜNDÜZ, Mehmet Akif

Kırsal alanların geri kalmışlığı gelişmiş ve gelişmekte olan ülkelerin en önemli sorunu haline gelmiştir. Birçok ülke ve sivil toplum kuruluşu kırsal kalkınma bağlamında birçok önemli politikalar uygulamış ve proje üretmiştir. Üretim temelinde önemli derece mali kaynak sunmuştur. Ancak göz ardı edilen en büyük eksiklik kırsal alanda üretilen ürünlerin nasıl pazarlanıp satılacağıdır. Dünyada önemli ölçüde gelişen e-ticaret kırsal kalkınmada yaşanan pazarlama ve satış eksikliğinin en büyük tamamlayıcı faktörü olabilmesidir. Ayrıca, e-ticaret kırsal kesimdeki tüketici için de alım gücüne katkı sa ...Daha fazlası
