A bi-criteria single machine scheduling with rate-modifying-activity
(Gazi Universitesi, 2013) Yucel Yilmaz Ozturkoglu; Öztürkoǧlu, Yücel
In this paper we consider a single machine scheduling problem with two criteria: minimizing both total flow time with total tardiness and minimize maximum tardiness with number of tardy jobs. Unlike the classical scheduling problems we use a job position deterioration which means that the job processing time increases as a function of the job position. Besides deteriorated jobs we also consider rate-modifying-activities which alter the efficiency of the deteriorating processor. This is the first paper to combine both time dependent processing times and problems with rate-modifying-activity in the bi-criteria objectives. To solve the new type of problem we introduce a new scheduling mathematical model which is based on one developed Ozturkoglu and Bulfin [1]. To analyze the efficiency of the mathematical model we use three different approaches. According to computational results up to 50 jobs can be solved in less than one minute. © 2023 Elsevier B.V.

(SPRINGER WIEN, 2025-05-27) Farzad Rotbeei; Mustafa Nuri Balov; Mir Jafar Sadegh Safari; Babak Vaheddoost
Droughts are the phenomenon of which their magnitude and frequency are forecasted to escalate over time primarily due to the impacts of climate change and global warming. Hence the potential consequences of the expected drought events are of the great importance in performing effective adaptation and regional mitigation strategies. The objective of the current study is to explore the consequences of climate change on the future droughts in K & uuml,& ccedil,& uuml,k Menderes Basin in western T & uuml,rkiye. This objective will be addressed by examining the outputs of four General Circulation Models (GCMs) incorporated within Phase 6 of the Coupled Model Inter-comparison Project (CMIP6) with particular emphasis on two contrasting emission trajectories: SSP2-4.5 and SSP5-8.5. The daily precipitation and temperature projections are then utilized in determination of the so-called Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI) drought indices with consideration to 2015-2039 as near future 2040-2069 as mid-term future and 2070-2099 as late future time frames. According to projections based on the SSP2-4.5 and SSP5-8.5 scenarios the number of dry months is anticipated to escalate by approximately 26.12% and 39.80% respectively toward the end of the twenty-first century (2070-2099) in contrast to the reference period (1985-2014). Results of the current study provide valuable insights for developing adaptation strategies to address future consequences of drought events in the K & uuml,& ccedil,& uuml,k Menderes Basin amid evolving climate conditions.

(Taylor and Francis Inc. 325 Chestnut St Suite 800 Philadelphia PA 19106, 2016-08-12) Ali Kemal Çakir; Huseyin Gunerhan; A. Hepbasli; Hepbasli, A.; Gunerhan, H.; Cakir, A. K.
The main objective of this study is to investigate the use of the landfill gas as potential energy and electricity obtained from the municipal solid waste (domestic industrial medical waste and sewage sludge) stored regularly in the Harmandali solid waste landfill area within the boundaries of the contiguous area of Izmir. The most important factor in making a decision about energy potential in the landfill is the amount of methane in the landfill gas. There are several approaches that have been used to determine the amount of the landfill gas. In this study three different methods and one approach in the literature were used for this purpose. The methods used are the Multi-Phase the LandGEM and the IPCC 2006. The results of the landfill gas obtained using the three methods namely the Multi-Phase the LandGEM (k = 0.35 k = 0.1 and k = 0.05) and the IPCC 2006 were as follows respectively: 291897215 792073359 769734749 681685027 and 491752247 m3. It may be concluded that the Harmandali Landfill has high landfill gas potential based on the measurements and mathematical methods used in the Harmandali landfill. © 2017 Elsevier B.V.

A Comprehensive Overview of Foreign Language Teachers' Professional Development: Self-directed and Institutional Professional Development Activities of English Teachers in Turkey
(Turkish Education Association, 2024-07-30) Çaǧri Özköse-Biyik; Oner Uslu; Bıyık, Çağrı Özköse; Uslu, Öner
When the literature on the professional development of English as a foreign language (EFL) teachers is examined professional development predominantly encompasses institutional activities. This study critically examines conventional definitions and practices related to the professional development of EFL teachers arguing that in line with the demands of the era teachers' professional development should also include self-directed individual activities. However for professional development activities to contribute to the ultimate goal of student learning it is important for the organizational culture in which teachers are situated to be supportive of their professional development. To seek answers to research questions about how the institutional and self-directed activities carried out by EFL teachers in Türkiye and the organizational culture influence these activities an exploratory sequential strategy was employed in the research. First qualitative data were collected and then quantitative data were collected through a survey tool developed based on the qualitative data. Comprehensive individual interviews were conducted with a total of 28 teachers across Turkey and survey data were collected from 819 teachers. The findings are presented as self-directed (unstructured) professional development activities (e.g. use of search engines reading news websites watching videos/series etc.) and institutional (structured) professional development activities (participation in national and international conferences etc.). The necessity of foreign language teachers being involved in many individual activities through self-direction beyond their participation in activities planned by institutions for the professional development of a foreign language teacher is discussed. The study proposes a comprehensive perspective on the concept of professional development related to EFL teachers and offers recommendations for the field of foreign language teacher education. © 2024 Elsevier B.V.

(EMERALD GROUP PUBLISHING LTD, 2021-07-26) Cansu Turan; Yucel Ozturkoglu
Purpose There is a large number of perishable foodstuffs produced stored distributed and delivered daily around the world. Almost all except for root vegetables are sensitive products to temperature. Thus adopting uninterrupted and appropriate logistics activities with predetermined range of temperature from production site until end-user is critical for ensuring required quality and safety. If a mistake is made during either transport or storage it not only becomes risky for human health but also generates huge food waste for the environment and negative economic impact for food providers. Therefore this study aims to identify all potential factors affecting the cold chain performance in the food industry and to design a framework that includes these factors. This framework is also a roadmap for managers food providers and logistics parties for sustainable cold chain management. Design/methodology/approach Considering tangible and intangible potential criteria the ultimate goal of this study is to identify potential criteria affecting cold food chain performance and propose a conceptual framework including 12 main criteria. Next the importance order of each criterion and the causal relationships between them are determined. In this study this relationship among criteria is analyzed by using fuzzy Decision-making Trial and Evaluation Laboratory (DEMATEL) approach because of its ability to solve complex problems by ensuring causal relationship among factors additionally to determine importance order. Finally suggestions for administrative implications are presented. Findings Fuzzy DEMATEL was used to explain the causal link and importance order among identified drivers. The analysis shows that five criteria (C1 C3 C8 C9 and C12) belong to cause (influential) groups and remaining seven criteria belong to effect (influenced) groups. The highest influential criterion is staff (C8) and is followed by technical issues (C9) as the second most influential factor. Additionally top three most important factors are traceability (C7) staff (C8) and cold transportation (C5). According to the numerical results of fuzzy DEMATEL implementations suggestions for managerial implementations are presented. Practical implications The main contribution of the study is to propose meaningful suggestions for managerial implications about sustainable cold chain in food industry for businesses and to examine causal relations between criteria and to rank criteria in descending importance order. Originality/value To the best of the authors' knowledge this is the first study that focuses on determining the potential criteria affecting cold supply chain performance both theoretically and empirically in the sustainability environment. What are the enablers that affect the cold food supply chain stages is the research question of this study.

(SPRINGER INDIA, 2017-06-28) Shiva Moslemi; Mohammad Hossein Zavvar Sabegh; Abolfazl Mirzazadeh; Yucel Ozturkoglu; Eric Maass
Quality of medical and pharmaceutical products has a key role in healthcare systems such as hospitals for better services to patients. This study proposes a comprehensive multi-objective mathematical model in healthcare supply chain considering quality and green concepts. The proposed model includes three objective functions. The first minimizes total manufacturing costs including transportation, purchasing maintenance deterioration setup recycling collecting and disposal costs. The second maximizes quality level of production. The third minimizes environmental effects of the products and transportations. The proposed model is complicated because of its nature and listed in the NP-hard. Hence we use NSGAII approach for solving this model. The numerical example illustrates steps of the solution method. The solution representation for 4 suppliers 2 recycling centers and 3 productions shows for supplier 1 (1100 600 1000) and supplier 2 (1000 900 400) recycling center 2 has a good performance and for supplier 3 (700 500 800) and supplier 4 (400 950 0) recycling center 1 has a good performance. Then we need to improve the performance of the rest recycling centers per supplier. To measure the capabilities of multi-objective meta-heuristics we used Number of Pareto solutions spacing metric and quality metric criteria. Finally the results show that the proposed algorithm has high quality to solve the model.

The growing pollution in the environment and the negative shift in the global climate compel authorities\rto take action to protect the environment and human health. Transportation is one of the major contributors to this\renvironmental decay. The harmful gases released to the air by the vehicles using petroleum fuel increase each day. One\rof the solutions is to make a gradual transition to electric vehicles. A major part of manufacturing an electric vehicle\ris to produce an efficient electric motor and battery for it. Reducing the manufacturing and operating costs of these\rcomponents will result in reducing the overall costs of electric vehicles. In this study a new variant of the electric\rtravelling salesman problem with time windows (E-TSPTW) was proposed. The objective function of the problem is to\rminimize the required initial battery capacity of the electric vehicle. For this goal a new energy consumption model\rconsidering the load of the vehicle was proposed with three scenarios. The proposed model was solved with a hybrid\rsimulated annealing algorithm for all these scenarios. The performance of the proposed method was compared to the\rsolutions found by a mixed integer linear programming model. The experimental results on the benchmark instances\rshow that up to a 35% reduction in initial battery capacity hence reduction in its cost is possible.\r

A new warehouse design problem and a proposed polynomial-time optimal order picking algorithm
(GAZI UNIV FAC ENGINEERING ARCHITECTURE, 2018-04-06) Omer Ozturkoglu; Deniz Hoser; Hoşer, Deniz; Öztürkoğlu, Ömer
In this study we propose a new design problem that relates to orientation of cross aisles in warehouses. In this problem the main orthogonal cross aisle which is very common to be seen in warehouses to facilitate travel between locations is planned to be designed as discrete manner such as tunnels along picking aisles. Hence the problem of locating these tunnels along picking aisles so as to increase efficiency of order picking operations which is one of the most costly and the most related operations with the order delivery time in warehouses is propounded. Additionally we develop a new dynamic programming based polynomial time algorithm to calculate optimal length of order picking tour in this new design problem. Hence this algorithm provides very quick solutions even for large pick list sizes. The computational performance of this algorithm is compared with Held-Karp branch and bound algorithm which is a well-known algorithm for travelling salesman problem. Last we solve an example problem and explain how the algorithm is implemented to generate optimal tour.

A sustainable decision-making framework to evaluate land and seaside disposal options for tunnel spoil: A case study of Trabzon
(SCIENCE PRESS, 2025-05) Ali Ersin Dincer; Abdullah Demir; Sevki Ozturk; Kutay Yilmaz; Yilmaz, Kutay; Dincer, Ali Ersin; Demir, Abdullah; Ozturk, Sevki
Sustainable urbanization is essential for developing cities. To ensure the success of planned construction projects designers must prioritize sustainability by lowering emissions and reducing costs. Tunnel projects are common worldwide but disposing of the excavated material presents a significant challenge due to unsuitable geographic conditions. While coastal cities with mountainous terrains have historically used spoil for sea filling this study offers alternative landside options to promote sustainability. By using a conventional analytical hierarchy process (AHP) method for multi-criteria decision-making (MCDM) the study evaluates land use sustainability slope and drainage lines as constraints for the AHP method. The transportation-related greenhouse gas (GHG) emissions are also considered to reduce environmental damage. Particle swarm optimization is used to determine the minimum transportation distance from the excavation zone to the dumpsite. As a sub-criteria of land use the seaside is also considered a dumpsite compared with other options on the land side. The spatial analysis results of the case study show that suitable landside sites are available for the Trabzon tunneling project. Although coastal areas in Trabzon have been used for spoil dumping for filling purposes in the past landside deposition is a viable alternative. The suitability ranks of land and coastal filling options are relatively similar and selecting the seaside as the dumpsite for the Trabzon tunneling project reduces CO2 emissions. By adopting sustainable practices we can realize a better future for our cities and the environment.

Addressing pipeline security regime of the prospective regional energy hub Turkey
(PALGRAVE MACMILLAN LTD, 2012-10-08) Emre Iseri
Approximately 35 per cent of the world's oil and 75 per cent of its natural gas output are being transported through pipelines. This has rendered the security of critical energy infrastructures (CEIs) such as pipelines as a vital issue of concern even more so following the events of 9/11. This is the case for transit countries located in the Near East such as Turkey where the security of energy infrastructure is at stake daily. Although concerns are growing about a tight energy market with chronically volatile high oil prices and a lack of reliable energy resources states and companies cannot afford to keep their CEIs unprotected. This is an important issue for net energy importer Turkey with its pledge to become the fourth largest energy artery of Europe and its growing energy thirst. In the light of these the paper argues that it is vital for Ankara to address the kinds of threats (that is terrorism vandalism theft) that Turkey's energy pipelines face on the way to becoming a regional energy hub.

Adolescents' eveningness chronotype and cyberbullying perpetration: the mediating role of depression-related aggression and anxiety-related aggression
(TAYLOR & FRANCIS LTD, 2018-09-05) Sule Betul Tosuntas; Sabah Balta; Emrah Emirtekin; Kagan Kircaburun; Mark D. Griffiths; Kircaburun, Kagan; Emirtekin, Emrah; Balta, Sabah; Tosuntaş, Şule Betül; Griffiths, Mark D.
Recent empirical evidence has indicated a positive relationship between university students' evening-type chronotype and their cyberbullying perpetration (CBP) scores while controlling for gender and Big Five personality dimensions. The aims of the present study were (i) to replicate the results of the aforementioned study with an adolescent sample and (ii) to examine the mediating role of depression anxiety and aggression on the relationship between chronotype and CBP. In order to investigate these aims 493 high-school students were recruited to complete a survey that included the Reduced Morningness-Eveningness Scale Short Depression Scale State-Trait Anxiety Inventory Short Form Aggression Questionnaire and Cyberbullying Offending Scale. Results indicated that while females had higher depression and anxiety scores males scored higher on CBP. Path analysis showed that aggression depression-related aggression and anxiety-related aggression fully mediated the relationship between evening-type chronotype and CBP. There were also significant gender differences in the model. Furthermore physiological factors had an indirect effect on CBP via psychological risk factors and emotion-related negative behaviors.
Agop Salomon and Despina: Content Analysis of Non-Muslim Representations in Yesilcam Cinema
(ROUTLEDGE JOURNALS TAYLOR & FRANCIS LTD, 2022-04-19) Dilara Balci Gulpinar
In the years between 1956 and 1975 Turkish film production boomed. These two decades were also the very last years in which non-Muslim characters were still appearing in a wide range of productions and so they offer an important window into the representation of non-Muslims in the Turkish cinema of this period known as Yesilcam. This essay explores these representations by analyzing 82 films featuring 121 Turkish Greek Armenian and Jewish characters. The representation of these non-Muslims is considered through the characters' importance to the plot their names genders manners ways of speaking occupations families religious activities relationships with Turkish Muslim characters and the stereotypes associated with them. Unsurprisingly non-Muslim characters often occupy minor one-dimensional - and sometimes threatening - roles as these films are concerned with the stories of Turkish Muslim characters who not only comprise the dominant group in society but also the vast majority of the audience. Analysis of the films indicates that representations of non-Muslim characters that originate in traditional Turkish art forms have undergone considerable change in films due to the influence of increasing Turkish nationalism together with the Turkification policies of the Turkish state.
An ALNS-Based Decision Support System for Scheduling and Routing in Home Healthcare with Lunch Break Constraints
(Growing Science, 2026) Ozsakalli, Gokberk; Qadri, Syed Shah Sultan Mohiuddin; Ozturkoglu, Omer
This study addresses the daily scheduling and routing problem for home healthcare workers while incorporating lunch break requirements. The Home Healthcare Scheduling and Routing Problem is analysed alongside its common constraints, including patient and caregiver time windows, caregiver qualifications, and mandated breaks. To address this, four different variants of an effective Adaptive Large Neighbourhood Search (ALNS) algorithm were developed to provide high-quality solutions. The algorithms demonstrate significant efficiency, solving 30-patient instances optimally within an average of 12 seconds. For scenarios involving 100 patients, they maintained robust performance with a slight increase in computational time of about 54 seconds. Results indicate operational efficiency improvements of up to 36% through optimized travel routes and patient visitation schedules. To translate these findings into practice, a decision support system, the Home Healthcare Decision Support System (HHDSS), was designed to assist administrators by automating the complex task of scheduling and routing of caregivers. Tested using realistic patient data generated from Turkey, the system effectively allocates healthcare resources and improves responsiveness. Overall, the proposed framework shows strong potential as a valuable practical tool for improving the responsiveness and efficiency of home healthcare logistics.

An Empirical Evaluation of Feature Selection Stability and Classification Accuracy
(GAZI UNIV, 2024-06-01) Mustafa Buyukkececi; Mehmet Cudi Okur; Büyükkeçeci, Mustafa; Okur, Mehmet
The performance of inductive learners can be negatively affected by high -dimensional datasets. To address this issue feature selection methods are used. Selecting relevant features and reducing data dimensions is essential for having accurate machine learning models. Stability is an important criterion in feature selection. Stable feature selection algorithms maintain their feature preferences even when small variations exist in the training set. Studies have emphasized the importance of stable feature selection particularly in cases where the number of samples is small and the dimensionality is high. In this study we evaluated the relationship between stability measures as well as feature selection stability and classification accuracy using the Pearson 's Correlation Coefficient (also known as Pearson 's Product -Moment Correlation Coefficient or simply Pearson's r ). We conducted an extensive series of experiments using five filter and two wrapper feature selection methods three classifiers for subset and classification performance evaluation and eight real -world datasets taken from two different data repositories. We measured the stability of feature selection methods using a total of twelve stability metrics. Based on the results of correlation analyses we have found that there is a lack of substantial evidence supporting a linear relationship between feature selection stability and classification accuracy. However a strong positive correlation has been observed among several stability metrics.
