In this research, a framework is to be proposed to model the safety performance in construction sites. Determinants of safety performance are to be defined through extensive literature review and a multidimensional safety performance model is to be developed. In this context, a questionnaire is to be administered to construction companies with sites. The collected data through questionnaires including linguistic terms are then to be defuzzified to get concrete numbers by using fuzzy set theory which provides strong and significant instruments for the measurement of ambiguities and provides the opportunity to meaningfully represent concepts expressed in the natural language. The validity of the proposed safety performance model, relationships between determinants of safety performance are to be analyzed using the structural equation modeling (SEM) which is a highly strong multivariable analysis technique that makes possible the evaluation of latent structures. After validation of the model, a safety performance index assessment tool is to be proposed by the help of software. The proposed safety performance assessment tool will be based on the empirically validated theoretical model.

Using the balanced scorecard as a safety management tool in construction companies : a qfd approach Şimşek, Burak; Gündüz, Murat; Department of Civil Engineering (2006) The aim of this thesis is to propose a safety management framework for construction companies. A literature review was performed to identify significant factors that would improve safety performance. Two management tools are used within the scope of this study: the balanced scorecard and quality function deployment (QFD). Strategic goals are established for each perspective of the balanced scorecard: financial and cultural, employee, process and learning and growth. Afterwards, a questionnaire was prepared ...
A Fuzzy structural equation model to analyze relationships between determinants of safety performance in construction sites: development of a safety performance index assessment tool Özdemir, Mustafa; Birgönül, Mustafa Talat; Department of Civil Engineering (2015) The principal aim of this study is to examine the relationships between determinants of safety performance in construction sites. In this study, 168 observable variables and 16 latent dimensions affecting safety performance of construction sites were collected together from detailed literature review, expert opinions and face-to-face interviews with 15 construction safety professionals. Relationships between observed variables and latent dimensions of safety performance of construction sites were studied an...
A methodology for reliability-based design of rock slopes DUZGUN, HSB; Yücemen, Mehmet Semih; Karpuz, Celal (Springer Science and Business Media LLC, 2003-04-01) A reliability-based methodology for the design of rock slopes, that can easily be implemented by the practicing engineers is proposed. The advanced first-order second-moment (AFOSM) method is adopted as the reliability assessment model and its application is illustrated for the case of plane failure. A model is developed within the framework of first-order second-moment approach to analyze the uncertainties underlying the in situ shear strength properties of rock discontinuities. Here, particular emphasis i...
A Method for Facilitating 4D Modeling by Automating Task Information Generation and Mapping Altun, Murat; Akçamete Güngör, Aslı (2018-10-04) 4D modeling integrates 3D model with project time schedule to provide virtual simulation for identifying spatio-temporal problems earlier in construction projects. However, constructing a 4D model takes a significant amount of time and is prone to man-made errors due to its manual steps and repetitive nature. Therefore, in this study, a model based two-phase method is developed to facilitate linking 3D model with the schedule by automating the cumbersome steps. In the first phase, 4D Task IDs are created an...
A Mixed integer programming method for pareto front optimization of discrete time cost trade-off problem Bilir, Mert; Sönmez, Rifat; Atan, S. Tankut; Department of Civil Engineering (2015) There is a reverse relationship between the activity durations and costs in construction projects. In scheduling of construction projects, the project duration can be compressed (crashed) by expediting some of its activities in several ways including; increasing crew size, working overtime, or using alternative construction methods. As a result, when duration of a critical activity is decreased, its cost increases and project duration decreases. In construction projects, resources are usually available in d...
