Türkiye'deki küçük ev aletlerinin atık yönetimi için Bayes ağıyla bir sistem dinamiği modeli

Nowadays sustainability is one of the most important subjects in the developing world. Thanks to sustainability, waste management also gains more importance. Waste management is composed of many sub-areas in which liquid, gas or solid wastes are treated. The waste category that will be studied in this thesis is waste of electric and electronic equipment (WEEE) under solid wastes. Turkey is a country whose household appliances sector is outstandingly large. Furthermore, many small household appliances are thrown away or destroyed due to end of life or quality issues. Most of those wastes do not go through any treatment process even if Turkey has collection and recovery targets for all WEEE categories. As they are not properly treated, the process to destroy without reusing or recycling them causes environmental damage. The aim of this thesis is to put forward a system dynamics model for increasing recovery options of waste of small household appliances in electric and electronic sector, which is not treated in an environmentally friendly way. Besides, in this thesis, Bayesian network has been used for evaluating the probability of decision variable in order to understand proposed system dynamics model. The proposed model provides decrease in environmental damage. In this model, Anylogic program will be used for the simulation of the proposed system dynamics model. Different scenarios will be also conducted to give recommendations on how the whole system works in the case of Turkey by using Netica Bayesian Network program.
