Abstract

Bu çalışmanın amacı Türkiye’de PM₁₀ ve SO₂ kirleticileri konsantrasyonları bakımından benzer davranışa sahip hava kirliliği izleme istasyonlarını belirlemek ve böylece izleme maliyetini ve bilgi fazlalığını azaltmaktır. Bu amaca yönelik olarak, otoregresif modele dayanan Bulanık k-Medoidler (BKM) algoritması kullanılmıştır. Yapılan analizler sonucunda, izleme istasyonlarındaki bilgi fazlalılığının ve bununla birlikle izleme maliyetinin PM₁₀ hava kirleticisi için yaklaşık olarak %78.5, SO₂ hava kirleticisi için  %73.5 azaltılabileceği sonucunda ulaşılmıştır.

Time Series Clustering’s application to identifying of information redundancy at air pollution monitoring stations in Turkey

Abstract

The aim of study is to determine the monitoring stations having similar behavior with respect to PM₁₀ and SO₂ concentrations and thus decrease monitoring cost and information redundancy. For this purpose, autoregressive model based Fuzzy K-medoids algorithm is used. At the results of analyses, it has been concluded that information redundancy in monitoring stations and thus monitoring cost can be decreased approximately 78.5% for PM₁₀ air pollutant, 73.5% for SO₂ air pollutant.
