The limited natural resources and their negative environmental effects increase the interest in alternative energy sources. The decrease in oil resources and the environmental problems caused by these resources have increased the studies for electric vehicles. This study presents descriptive statistics on the charging station locations for electric vehicles and relationships between studies by author, country, citation, and occurrence. This will provide a way for researchers to obtain detailed information about their studies into the locations of electric vehicle charging stations. This study examined 212 studies in the “Web of Science” database from 2011 to 2022. Network analysis was conducted in this research using the Vosviewer and R software. In this context, descriptive statistics are first provided. In the section on descriptive statistics, basic facts about the studies are shown along with the annual scientif...

Ancak blokzincir teknolojisinin tedarik zinciri yönetimi alanında kullanımı ile ilgili henüz az sayıda çalışma bulunmaktadır. Farklı çalışmalarda ayrı ayrı ele alınan tedarik zinciri izlenebilirliği ve tedarik zinciri sürdürülebilirliği bu çalışmada blokzincir teknolojik altyapısıyla değerlendirilmektedir. Çalışmada yöntem olarak örnek olay yöntemi benimsenerek blokzincir projelerinin örnek olayları paylaşılmıştır. Blokzincir teknolojik altyapısının kullanımının tedarik zinciri şeffaflığını; izlenebilirlik ve sürdürülebilirlik açısından olumlu yönde etkileyeceği düşünülmektedir.

Forecasting of these demands allows states to use their resources effectively. Artificial intelligence-based forecasting models play an important role in the forecasting of medical equipment demand during infectious disease periods. In this study, a deep model approach is presented, which is based on a multilayer long short-term memory network for forecasting of medical equipment demand and outbreak spreading, during the coronavirus outbreak (COVID-19). The proposed model consists of stages: normalization, deep LSTM networks and dropout-dense-regression layers, in order of process. Firstly, the daily input data were subjected to a normalization process. Afterward, the multilayer LSTM network model, which was a deep learning approach, was created and then fed into a dropout layer and a fully connected layer. Finally, the weights of the trained model were used to predict medical equipment demand and outbreak spreading in the following days. In experimental studies, 77-day COVID-19 data collected from the statistics data put together in Turkey were used. In order to test the proposed system, the data belonging to last 9 days of this data set were used and the performance of the proposed system was calculated using statistical algorithms, MAPE and R 2. As a result of the experiments carried out, it was observed that the proposed model could be used to estimate the number of cases and medical equipment demand in the future in relation to COVID-19 disease.

Internet of things applications can be seen in different areas, such as smart cars, smart homes, smart cities, agriculture, healthcare, industry, etc. This study focuses on the industrial part. Industrial internet of things (IIoT) means internet of things (IoT) applications for industrial usage. IIoT give a chance to enterprise for tracking supply chains, monitoring production line operations, and real-time consumption of energy, managing stock, and transportation decisions. This study used case study method for developing theory about IIoT's contribution to enterprise productivity. IIoT applications can be adapted to which operations of the enterprise, and how it will contribute to enterprise productivity is explained in this chapter. The chapter discusses the projects that are within the vision of IIoT but not yet implemented and concludes wi...

Therefore, it is necessary to understand the factors that affect service innovation. In the few studies conducted on different sectors, the relationship between co-production and IT and service innovation has been tried to be tested separately. In this study, the mediating role of coproduction in the effect of information technologies on service innovation in the tourism sector has been investigated. In this way, it will contribute to the literature by investigating the effect of IT (directly and indirectly) and co-production (directly) on service innovation in the tourism sector. In the study data collected from 222 hotel managers were firstly subjected to validity and reliability analysis. Then, mediation analysis was applied within the scope of hypothesis tests. According to the results obtained, coproduction has a mediating role in this relationship. In the study, it was concluded that the IT capabilities of the hotels enable them to create service innovations through production together with online travel agencies.

The sample of the study consists of company managers operating in the manufacturing sector in Turkey. An online survey was sent to company managers through connections established on LinkedIn and an analysis was carried out with the data collected from 414 participants. As a result of the analysis, it has been determined that environmental uncertainty has a direct, significant and positive effect on competitive advantage. In addition, the results of the research show that supply chain integration and supply chain agility have a partial mediating role in the relationship between environmental uncertainty and competitive advantage. According to the results of this study, in conditions of high environmental uncertainty, companies can increase their supply chain agi...

The waste collection phase of the recycling process requires interactive transportation that uses a reverse logistics flow from customers to recycling facilities. Businesses need to create appropriate network structures to carry out these activities at minimum cost. This study has developed a model, based on reverse logistics, of collecting products from customers and sending them to warehouses and then to recycling facilities. The chance-constrained programming (CCP) approach was used to regulate the constraints involving stochastic demand in the model. Linearization was performed using the linear approximation method. The cost of transportation from Initial Collection Points (ICP) warehouses to recycling facilities is the most influential component on the objective function. This linearized model was solved by...

Uluslararası ticaretin etkisiyle beraber denizyolu taşımacılığının da önemi giderek artmaktadır. Denizyolu taşımacılığının en önemli bölümünü ise konteyner taşımacılığı oluşturmaktadır. Konteyner taşımacılığının daha etkin bir şekilde yapılmasını sağlayabilmek için limanların verimliliğini arttırmak gerekmektedir. Liman yönetimlerinde farklı ülkelerde farklı stratejiler uygulanmasına karşın, hepsinin ortak amacı limanlardaki etkinliğin ve verimliliğin arttırılmasıdır. Bu çalışmada Amerika Birleşik Devletleri'nde yer alan konteyner limanlarının etkinlik durumları incelenmiştir. Çalışmada limanların verimliliğini belirleyebilmek için gerekli olan girdi ve çıktı değişkenleri belirlenmiş, devamında ise Hicks-Moorsteen ve Malmquist yöntemleri kullanılarak limanların verimlilikleri hesaplanmış ve etkinliği en yüksek olan limanlar belirlenmiştir. Ayrıca limanlardaki yıllara göre verimlilik değişimleri tespit edilmiştir. Hesaplamalar sonucunda elde edilen sonuçlar dikkate alınarak iki endeks karşılaştırılmıştır. Sonuçlar incelendiğinde ise her iki yöntem sonucunda elde edilen verimlilik analizlerinde ciddi benzerlikler olduğu gözlemlenmiştir. Verimliliği düşük olan limanların ise etkinliğini arttırmak için yapılması gerekenler hakkında önerilerde bulunulmuştur.

It has been tried to create a roadmap for producers to overcome existing and similar crises with proactive solutions. The reflections of the global crisis on production are carefully examined in the study. The epidemic is not limited to a single country, but affects all parts of the world, leaving supply chains and manufacturers in a difficult situation. Just as the concept of the new normal for consumers has come to the fore, the necessity of adapting to the new norm by implementing certain technologies that have been emphasized in recent years is now more clearly felt for manufacturers. The pandemic process experienced and the difficulties and enablers that producers face/will face afterwards are explained in detail under the headings of human resource management, flexibility, sourcing, technology level, logistics.
