This paper mainly deals with the evaluation of suppliers and allocating orders using hybrid multi criteria decision making such as rough set theory, analytic hierarchy process and grey relational analysis. Selection of supplier includes both quantitative and qualitative factors. Qualitative factors are analyzed by rough set theory, analytic hierarchy process to determine the weight of each supplier. Quantitative factors are integrated with the weights of each supplier to evaluate the best supplier. The model has been applied to supplier selection of a high technology company named Multi-Flex Lami-Print Ltd which manufactures Flexible Packaging materials. Based on the numerical calculations this model can be considered as an effective model which is applicable to all type of industries
