This document describes a fuzzy logic-based decision support system to help business executives select appropriate e-business models. It discusses existing frameworks for classifying e-business models and their limitations. The proposed system uses fuzzy logic to capture executives' linguistic assessments of key business measures. It assesses each business dimension using fuzzy calculations and rules. A prototype was tested with positive feedback from business executives. The system aims to assist decision-making by narrowing the search for suitable e-business models.
