An improved Decision Support System based on the BDM (Bit Decision Making) Method for supplier selection using Boolean Algebra

Abstract

Based on the BDM (Bit Decision Making) method, the present work presents two contributions: first, the illustration of the use of the technique known as SOP (Sum Of Products) in order to systematize the process to obtain the correlation function for sub-system's mathematical modelling, and second,the provision of capacity to manage a greater than binary but a finite-discrete set of possible subjective qualifications of suppliers at any criterion.
