Evaluating Adoption Factors for Robotic-Assisted Surgery With the Analytical Hierarchical Process
(01. Izmir Institute of Technology, 2024) Sarıgöl, Işın Sözen; Dindaroğlu, Burak; Başoğlu, Ahmet Nuri
The objective of this master's dissertation is to evaluate adoption factors for robotic-assisted surgery (RAS) using the Analytical Hierarchy Process (AHP) as its evaluation methodology. Robotic-assisted surgery is used in various surgical fields. It is mainly used as a tool in numerous disciplines' minimally invasive surgery procedures (MIS). Since it has so many different application areas and actors, the determination of its adoption factors and evaluation process of these factors' priorities for surgeons is a highly complex issue that includes multicriteria of decision-making and numerous surgeons. A comprehensive list of these possible adoption factors recognized by conducting an extensive literature review, was picked and chosen. First, we had 310 factors mentioned in the literature that have a potential impact on the adoption process of the RAS. We have reduced these to 20 factors that are categorized under five different main criteria. By this, a unique AHP tree that is this thesis' contribution to the literature was developed. The research data was collected by an online survey from the surgeons of various disciplines working in Türkiye. Our final sample to evaluate priorities consisted of forty-one surgeon responses in total. The evaluation process consists of three steps: analyzing individual-based pairwise comparison matrices, their consistency rations, and their priority vectors. We executed the same workflow for the aggregated analysis for disciplined-based and all aggregation. Results are examined in detail and concluded with insightful interpretations.
Design and Techno-Economic Analysis of a Smart Solar Greenhouse
(01. Izmir Institute of Technology, 2022) İçöz, Didem; Ebil, Özgenç; Dindaroğlu, Burak
The aim of this study is to examine the combination of agriculture and energy, which are two indispensable concepts for the existence of humanity, more efficiently. Energy, which is an indispensable part of human life, is at the top of the issues discussed in the world agenda today as it was in the past. Energy continues to be an indispensable factor in the economic and social development of countries, and therefore in increasing social welfare. With the developments in the agricultural sector, the energy need of the sector is increasing and energy diversity is important. In parallel with the world population, the demand for foodstuffs is increasing day by day. In order to meet this increasing food demand, greenhouse cultivation, where high efficiency is obtained from the unit area, is gaining more and more importance all over the world. Providing optimum conditions according to the location and seasonal characteristics of the location is essential for greenhouse efficiency. The need to heat greenhouses to provide these conditions constitutes a substantial energy cost. However, it is a known fact that fossil fuels, which are one of the energy sources, cause global climate changes, as they are an important source of CO2, known as a greenhouse gas. In this context, approaches to the use of renewable energy sources in agricultural activities are of great importance for the development of the sector. This study was prepared to examine the use and techno-economic analysis of photovoltaic panels for the energy needs of greenhouses. The solar greenhouse, where optimum conditions are provided with the automation system, will generate income from electricity sales as well as agricultural income in the months when it produces more electricity than its self-consumption.
Grid-Connected Photovoltaic Systems for Fuel Stations: a Complete Techno-Economic Analysis
(01. Izmir Institute of Technology, 2022) Kılınç, Mehmet Emin; Ebil, Özgenç; Dindaroğlu, Burak
The purpose of this study, beyond being an engineering practice, is an attempt to overcome a bottleneck that has not been overcome so far with scientific methods and to use the power of science for the benefit of the environment, the public, fuel distribution companies, petrol stations and almost every part of the society. Due to rapid changes in in terms of technology, efficiency, environmental sensitivity, consumer preferences, cost structure and legal base, this study is investigating and making suggestions for oil station companies regarding on-grid photovoltaic applications. Successful management of the process depends on effective calculation including, system requirements considering local solar radiation and financials from many aspects. Considering that, many fuel station owners cannot effectively approach the technical, bureaucratic, and financial aspects of photovoltaic applications and that academic studies that will guide the interested parties in a package form are not sufficient, the importance of this study will be more clearly demonstrated. Information obtained through the literature review, applying the engineering economics models and also with a widespread field study including petrol stations, solar material supply and installation companies, health and safety company and bank. It has been tried to set a user’s manual for concerned parties both in, academia, oil & solar sector and financial system in Turkey.
