In this study, an approach is proposed to model and simulate the systems engineering process of design projects. One of the main aims is to model the systems engineering process, treating the process itself as a complex system. A conceptual model is developed as a result of a two-phase survey conducted with systems engineers. The conceptual model includes two levels of activity networks. Each first level systems engineering activity has its own network of second level activities. The model is then implemented in object oriented modeling language, namely SysML, using block definition diagrams and activity diagrams. Another aim is to generate a discrete event simulation model of the process for performance evaluation. For this purpose the SysML model is transformed to an Arena model using an Excel interface and VBA codes. Three deterministic and three stochastic cases are created to represent systems engineering process alternatives, which originate from the same conceptual model but possess different activity durations, resource availabilities and resource requirements. The scale of the project and the effect of uncertainty in activity durations are also considered. The proposed approach is applied to each of these six cases, developing the SysML models, transforming them to Arena models, and running the simulations. Project duration and resource utilization results are reported for these cases.

Experience reflection modelling as a generative research method in an educational case for sustainable product design Turhan, Senem; Doğan, Çağla (2014-01-01) A generative research method, namely Experience Reflection Modelling (ERM), has been developed aimed at helping students explore and reflect upon design considerations for sustainability in the idea generation phase of a design process. ERM has been integrated into a product design for sustainability project as part of the design education in the Department of Industrial Design at Middle East Technical University. This paper begins by providing an overview of the generative research approach, explaining its...
Agile and collaborative systems engineering Aşan, Emrah; Baykal, Nazife; Bıçakcı, Kemal; Department of Information Systems (2013) In this study, an agile and collaborative systems engineering approach is developed with specific focus on system of systems challenges. First, agility related problems are identified by an interview-based exploratory survey. Afterwards the novel approach is formulated to address agility problems in system of systems environments. The approach is based on eliciting existing knowledge, visualizing it by immediate modeling, verifying consistency of the knowledge by continuous review, and identifying and plann...
Refinements, extensions and modern applications of conic multivariate adaptive regression splines Yerlikaya Özkurt, Fatma; Weber, Gerhard Wilhelm; Department of Scientific Computing (2013) Conic Multivariate Adaptive Regression Splines (CMARS) which has been developed at the Institute of Applied Mathematics, METU, as an alternative approach to the well-known data mining tool Multivariate Adaptive Regression Splines (MARS). CMARS is based on given data and a penalized residual sum of squares for MARS, interpreted as a Tikhonov Regularization problem. CMARS treats this problem by a continuous optimization technique called Conic Quadratic Programming (CQP). This doctoral thesis adapts the CMARS ...
Integration of Generative Research and Sustainability into the Product Design and Development Process Turhan, Senem; Doğan, Çağla (null; 2012-07-05) To explore the relationships between the generative research and design for sustainability at the idea generation phase of the design process, a design research method that emerges from generative research approach “Experience Reflection Modeling” (ERM) has been developed and integrated into a design for sustainability project within the context of design education in the Department of Industrial Design at the Middle East Technical University (METU). The ERM method brings together 3D modelling, interview an...
Real-time hardware-in-the-loop simulation of electrical machine systems using FPGAs Üşenme, Serdar; Dilan, R.A.; Dölen, Melik; Koku, Ahmet Buğra (2009-11-18) This study focuses on the development an integrated software and hardware platform that is capable of performing real-time simulation of dynamic systems, including electrical machinery, for the purpose of hardware-in-the-loop simulation (HILS). The system to be controlled is first defined using a block diagram editor. The defined model is then compiled and downloaded onto an FPGA (¿Field Programmable Gate Array¿) based hardware platform, which is to interface with the controller under test and carry out the...
