Abstract: The purpose of this paper is to propose an improved lean manufacturing approach to enhance the sustainability performances of manufacturing processes. To do that, three phases are proposed. The first phase aims to propose an extended value stream mapping method to quantify the sustainability indicators and assess the manufacturing process. In the second phase, entropy method is used to determine the weights of indicators. In the final phase, the weights obtained from entropy method are used in fuzzy evaluation based on distance from average solution (EDAS) and fuzzy technique for order preference by similarity to the ideal solution (TOPSIS) to rank a set of kaizen events according to their ability to improve the sustainable indicators. The novelty and the main contributions of the proposed approach are proved by the development of an extended VSM method. Also, the proposed approach contributes by a new methodology for enhancing the application process of the conventional lean manufacturing approach. [Submitted 10 June 2020; Accepted 14 April 2021]
