Sustainable development requires scheduling and implementation of projects by considering cost, environment, energy, and quality factors. Using a robust approach, this study investigates the time-cost-quality-energy-environment problem in executing projects and practically indicates its implementation capability in the form of a case study of a bridge construction project in Tehran, Iran. This study aims to take into account the sustainability pillars in scheduling projects and uncertainties in modeling them. To model the study problem, robust nonlinear programming (NLP) involving the objectives of cost, quality, energy, and pollution level is applied with resource-constrained. According to the results, as time diminished, the cost, energy, and pollution initially decreased and then increased, with a reduction in quality. To make the model close to the real world by considering uncertainties, the cost and quality tangibly improved, and pollution and energy consumption declined. We applied the augmented ε-constraint method to solve the proposed model. According to the result of the research, with regard to the time-cost, time-quality, time-energy, and time-pollution charts, as uncertainty increases, the cost and quality will improve, and pollution and energy will decrease. The proposed model can be employed for all industrial projects, including roads, construction, and manufacturing.

A mixed integer model for optimization of discrete time cost tradeoff problem
Tatar, Ali Can; Bilir, Mert; Sönmez, Rifat; Atan, Sabri Tankut (null; 2016-06-25)
In construction projects, activity durations can be expedited by allocating additional resources. Decreasing activity durations by means of crashing, usually leads to increase in the direct expenses. This trade-off between time and cost is called as the time-cost trade-off problem. Since in practice many resources are available in discrete units, numerous research has focussed on the discrete version of this problem called the discrete time-cost trade-off problem (DTCTP). Achieving the project schedule that...
Investigation of layout optimization for offshore wind farms and a case study for a region in Turkey
Kaya, Baran; Oğuz, Elif; Department of Civil Engineering (2022-2)
In this thesis, the focus was to develop an optimization tool by using mathematical layout optimization methods aiming to increase the energy capacity or reduce the cost of an offshore wind farm. For this purpose, two wind farm layout optimization (WFLO) models were developed using genetic algorithm (GA): model (a) minimizing the cost of power for variable turbine number, model (b) maximizing the power generation for fixed turbine number. Wind speed and wind direction were assumed constant. Therefore, unlik...
An exploratory study on utilization of BIM for risk management
Kaya, Hazal Deniz; Dikmen, İrem; Atasoy, Güzide; Birgönül, Mustafa Talat (İstanbul Teknik Üniversitesi; 2020-11-14)
It is a well-known fact that BIM application in construction projects enables several advantages such as better collaboration and communication, effective project visualization before construction, more efficient cost estimation and scheduling, and an increase in productivity. Although many of these advantages that BIM contributes to construction projects may result in opportunities for better risk management, there are limited studies in the construction management literature that investigate this subject....
An Exploratory Multi-Objective Retrofit Decision-Making Process
Akin, Şahin; Işeri, Orçun Koral; Erdogan, Bilge; Gürsel Dino, İpek (2020-08-18)
The retrofit processes for buildings necessitates long-term planning and costly operations and requires a collaborative approach where a high number of alternative solutions should be explored by stakeholders. However, the evaluation of a range of retrofit solutions is a complex process wherein various design parameters and objectives are involved. The identification of the most effective solutions requires a collaborative evaluation in order to satisfy all stakeholders‘ expectations; however, during the de...
A Hybrid building extraction algorithm based on multilevel segmentation and boundary simplification
Yarkınoğlu Gücük, Oya; Düzgün, H. Şebnem; Department of Geodetic and Geographical Information Technologies (2017)
Building footprints have an important role in urban planning, infrastructure development, climate studies and disaster management. The precise knowledge of buildings serves as a primary source for interpreting complex urban characteristics and also helps decision makers with more realistic urban management. In this thesis, the building boundary extraction including a hybrid approach is proposed. Firstly, normalized Digital Surface Model (nDSM) of the study area is generated from aerial Light Detection and R...
