This study aims to create an interdisciplinary, multi-level design approach that is based on six degrees of freedom mathematical model. The model provides all disciplines to communicate with each other simultaneously, thanks to an automated process chain system. The main advantage of automatization of analyses for the design process is observing interdisciplinary effects clearly without wasting time and money. Instead of using only empirical relations, in this study, calculations are originating from trim and simulation analyses that are based on the equation of motions. Trim and simulation capability provides to increase the diversity of the analyses which can be considered in early design phases such as stability and control. However, these analyses require an integrated mathematical flight dynamic model, which is capable to solve analytical and differential equations numerically. This study explains how the model structure is created to perform analysis in the design and optimization process of the fixed-wing propeller-driven aircrafts. Throughout the whole design process, the methodologies which are followed up for the analyses and optimization, are reported. Besides investigating aircraft design methodologies, the model validation processes are also included to the study.

Modeling and Simulation of High Speed Railway Vehicle Dynamics Tuğçe, Yüksel; Ünlüsoy, Yavuz Samim (null; 2015-03-04) This study aims to provide mathematical model(s) for the simulation of high speed railway vehicles. The dynamic behavior of a high speed train is divided into three uncoupled motions: vertical, lateral, and longitudinal. Two models with different complexities are used to simulate vertical plane response of the vehicle to track vertical irregularities. Different wheel-rail contact formulations are utilized to simulate the lateral plane motion of the vehicle on tangent and curved tracks. For both vertical and...
Computer-aided planning and design of manufacturing simulation experiments Özdemirel, Nur Evin; Köksal, Gülser (1996-09-01) An simulation has become a major tool in studying discrete manufacturing systems, experimental design issues have started to receive much attention. Although the importance of proper experimentation is often emphasized in the literature on discrete event simulation, it is neglected in most practical simulation studies. The main reason for this neglect is that the design and analysis of a simulation experiment require expertise in experimental design methodology as well as familiarity with traditional statis...
Design as a Collaborative Process A Systematic and Constructive Model for Developing Play Material for Blind Visually Impaired Preschool Children Börekçi, Naz Ayşe Güzide Z. (2002-05-14) This paper discusses a design process lived through, during the application of a model derived from design methodology and devised towards attaining a particular task. The task was: Designing a play system to contribute to the pre-school blind child’s development of object permanence, sense of self, and spatial concepts. The model employed was based on a systematic and constructive framework towards ensuring consciously made decisions. The paper also discusses the field-testing in play situations of the sys...
A Methodology for cross-resolution modeling in DEVS using event-B refinement Kara, Ahmet; Oğuztüzün, Mehmet Halit S.; Alpdemir, Mahmut Nedim; Department of Computer Engineering (2014) This thesis proposes a software engineering solution for implementing simulations via composition of models at different resolution levels with the help of formal methods. Our solution provides a systematic methodology that offers a well-defined sequence of stages to obtain executable converters for entity resolution mapping, given the types of entity attributes that are exchanged at model interfaces and the mapping specifications. Our methodology relies on Event-B as the formal specification language and D...
