DEA-Based Benchmarking Models In Supply Chain Management: An Application-Orie...
Download Link > https://ertekprojects.com/gurdal-ertek-publications/blog/data-envelopment-analysis/
Data Envelopment Analysis (DEA) is a mathematical methodology for benchmarking a group of entities in a group. The inputs of a DEA model are the resources that the entity consumes, and the outputs of the outputs are the desired outcomes generated by the entity, by using the inputs. DEA returns important benchmarking metrics, including efficiency score, reference set, and projections. While DEA has been extensively applied in supply chain management (SCM) as well as a diverse range of other fields, it is not clear what has been done in the literature in the past, especially given the domain, the model details, and the country of application. Also, it is not clear what would be an acceptable number of DMUs in comparison to existing research. This paper follows a recipe-based approach, listing the main characteristics of the DEA models for supply chain management. This way, practitioners in the field can build their own models without having to perform detailed literature search. Further guidelines are also provided in the paper for practitioners, regarding the application of DEA in SCM benchmarking.

Kimya Sanayinde Su Tasarrufu İçin Karar Destek Sistemi
İndirmek çin Bağlantı > https://ertekprojects.com/gurdal-ertek-publications/blog/kimya-sanayinde-su-tasarrufu-icin-karar-destek-sistemi/
Bu bildiride, Türkiye’nin sanayileşmiş bölgelerinden Gebze’de bulunan bir temizlik kimyasalları fabrikası için geliştirdiğimiz ve 7 ay boyunca kullanılarak test edilen bir Karar Destek Sistemi (KDS) tanıtılacak ve yapılan çalışma özetlenecektir. Üretim planlamadan sorumlu fabrika çalışanları bu yeni sistemi uygulamaya aldıktan sonra firma haftada 1 tona yaklaşan su tasarrufu sağlamıştır. Su tasarrufunun yanısıra maliyet, enerji ve işgücü kazançları da gözlemlenmiştir. Temizlik kimyasallarının üretiminin planlamasında faydası ve kullanılabilirliği kanıtlanan bu sistem, ürünlerarası geçişin ürün karakteristiklerine göre yıkama gerektirdiği boya, tekstil, gıda ve diğer kimya sanayilerinde de kullanılabilme potansiyeline sahiptir.
Scoring and Predicting Risk Preferences
Download Link > https://ertekprojects.com/gurdal-ertek-publications/blog/scoring-and-predicting-risk-preferences/
This study presents amethodology to determine risk scores of individ-uals, for a given financial risk preference survey. To this end, we use a regression-based iterative algorithm to determine the weights for survey questions in the scoring process. Next, we generate classification models to classify individuals into risk-averse and risk-seeking categories, using a subset of survey questions. We illustrate the methodology through a sample survey with 656 respondents. We find that the demographic (indirect) questions can be almost as successful as risk-related (direct) questions in predicting risk preference classes of respon-dents. Using a decision-tree based classification model, we discuss how one can generate actionable business rules based on the findings.

Data envelopment analysis (DEA) has proven to be a useful tool for assessing efficiency or productivity of organizations, which is of vital practical importance in managerial decision making. DEA provides a significant amount of information from which analysts and managers derive insights and guidelines to promote their existing performances. Regarding to this fact, effective and methodologic analysis and interpretation of DEA solutions are very critical. The main objective of this study is then to develop a general decision support system (DSS) framework to analyze the solutions of basic DEA models. The paper formally shows how the solutions of DEA models should be structured so that these solutions can be examined and interpreted by analysts through information visualization and data mining techniques effectively. An innovative and convenient DEA solver, SmartDEA, is designed and developed in accordance with the pro-posed analysis framework. The developed software provides a DEA solution which is consistent with the framework and is ready-to-analyze with data mining tools, through a table-based structure. The developed framework is tested and applied in a real world project for benchmarking the vendors of a leading Turkish automotive company. The results show the effectiveness and the efficacy of the proposed framework.

Dairy Logistics: A Tutorial
This paper discusses fundamental issues in dairy logistics in a tutorial format. We summarize findings of more than twenty student groups who carried out independent literature surveys and interviewed professionals in the industry. The critical issues in carrying out dairy products logistics, the logistics strategies that are employed by dairy producers in the world and some newly introduced products in the industry and in what ways the introduction of these new products changes the logistics operations are pointed out. The importance of hygiene, cooling, time, humidity, cost, distance, flexibility and meeting the demand is emphasized under the subtitle of critical issues. Except those critical issues, there are some others like short shelf life, quality, emulsion, pasteurization, UHT which depend on the characteristics of the milk and milk products. Logistics strategies in dairy industry are studied by dividing it into two subtitles: the ones that are used in the world and the ones in Turkey. A benchmarking between Turkey and the world is also included at the end. As the variety of milk and milk products increase day by day, the new ingredients of new products also affects the transportation plans. Those impacts are also discussed as a part of our paper. Some descriptive drawings and figures are also embodied. Throughout this paper, only the production, warehousing and transportation of milk, cheese, yoghurt, and similar dairy products are discussed. Ice-cream especially is set out of the scope as it completely differs from actual dairy products as milk, cheese and yoghurt in the means of production and distribution.
