Sustainability Index (SI) Model by Using PCA

Abstract

The problems caused by the unbalanced and fragmented development has become more and more obvious. In order to help these government and organizations to make a better decision to give support to the country's most in need, we need to develop a model to assess the sustainability of a country. On the basis of the Ecology Health Index (EHI) Model, the Sustainability Index (SI) Model is established to describe and assess the sustainability of a country. To modify SI Model into a quantized model. There are three main steps: Selection, Standardization and Weight Determination of the Indicators. We use the Principal Component Analysis (PCA) method to determine the weighting factors of each indicator.
