Sustainable manufacturing is defined as the creation of goods and services using processes that minimize negative environmental impacts, conserve energy, e.t.c. It is important for a manufacturing firm to measure and assess environmental impact along with three different dimensions: enterprise, process and product. Every enterprise needs to track and asses its environmental impact for accountability reasons towards its consumers, employees, society and government. It is known that immeasurable things cannot be managed in the environmental systems. The Refrigerator Compressor Plant is one of the manufacturing firms that come across emission problem existing due to energy consumption. It is known that there is a direct relation between energy consumption and carbon emissions. In other words, energy optimization is a key to reduce carbon emissions. Therefore, energy optimization studies are made in this Plant. This research mainly focuses on modeling and simulation of a sustainable manufacturing system by the use of a crankshaft production line and optimization of auxiliary energy consumption per part, overall cost per part, and number of finished parts per shift of The Refrigerator Compressor Plant. Thesis study starts with the production line examination and data acquisition. Then, System model is prepared and run in Arena software using real data. For optimization study, Simulation model variables are used as inputs. Simulation model is used with integration of optimization solver, OptQuest. Finally, simulation-based multi objective optimization process is completed.

Extending the lifespan of small kitchen appliances for sustainable design : a research on product maintenance and repair with technical services in Ankara
Terzioğlu, Nazlı Gökçe; Doğan, Çağla; Department of Industrial Design (2013)
Growing environmental issues from global climate change, contamination and depletion of renewable and non-renewable resources to waste disposal have been resulted from unsustainable production and consumption patterns. Most of the mass-produced products are designed and produced for short lifespans without considering environmental and social effects. Since small kitchen appliances are lower priced compared to other household appliances, when a part of the product is broken, the whole product is disposed of...
Sustainability considerations on effective use of resources for small household appliances
Oğur, Dilruba; Doğan, Çağla; Department of Industrial Design (2014)
The use phase of many products’ lifecycle has significant impacts on the environment that are largely determined by the use behaviour. Yet, those impacts mostly remain unnoticed, since individuals are unaware of the potential environmental consequences of their everyday practices and interactions with products, and have insufficient means to find them out. This study explores and examines use patterns and behaviours throughout the use phase of the small household appliances, particularly electric tea makers...
Evaluating the use of satellite-based precipitation estimates for discharge estimation in ungauged basins
Soytekin, Arzu; Akyürek, Sevda Zuhal; Department of Civil Engineering (2010)
For the process of social and economic development, hydropower energy has an important role such as being renewable, clean, and having less impact on the environment. In decision of the hydropower potential of a study area, the preliminary condition is the availability of the gages in the area. However, in Turkey, the gages in working order are limited and getting decreased in recent years. Therefore, the satellite based precipitation estimates has been gaining importance to predict runoff for ungauged basi...
A framework for energy reduction in manufacturing process chains (E-MPC) and a case study from the Turkish household appliance industry
Uluer, Muhtar Ural; Gok, Gozde; FESCİOĞLU-ÜNVER, NİLGÜN; KILIÇ, SADIK ENGİN (2016-01-20)
Energy is a major input in the manufacturing sector. Its security and efficiency are of supreme importance to a nation's industrial activities. Energy consumption also has serious environmental impacts in terms of Greenhouse Gas (GHG) emissions. In order to use energy more efficiently, simply designing parts and planning manufacturing processes with an energy-aware mindset is insufficient; it is also necessary to model and assess the energy efficiency of a process chain from a holistic point of view. In thi...
An Analysis of public use bicycle systems from a product service system perspective
Keskin, Duygu; Brezet, Han C; Börekçi, Naz Ayşe Güzide Z.; Diehl, Jan Carel (null; 2008-04-21)
Recent studies on sustainability indicate that the concept of the Product-Service System (PSS) is a promising approach to dematerialise the economy and reduce the environmental impacts of industrial and consumption activities. Considering the urban scale, mobility is one of the challenges that should be addressed and improved for a better quality of life for residents and lower pollution levels for the environment. In this respect, this study aims at analysing Public Use Bicycle (PUB) systems from a PSS per...
