Data Normalization for Root Assessment Methodology

Abstract

Data standardization is considered as mandatory work when applying most Multi-Criteria Decision Making (MCDM) methods. This study was conducted to identify the appropriate data standardization methods in combining with the RAM (Root Assessment Method) method. Thirteen different data normalization methods were applied in combining with the RAM method to solve the different problems. Among the thirteen tested data normalization methods, there is an available data normalization method from RAM method. In addition to this one, this study proposed another data normalization method that is determined to be suitable when combining with the RAM method.
