This paper presents a framework that builds and assesses the sustainability of the manufacturing system with combined lean and agile concepts. Analytical Hierarchy Process and Analytical Network Process are identified as suitable methodologies to analyze the model. The model is validated in an Ayurveda Pharmaceutical industry to identify the most important factors of lean and agile manufacturing that build and enable the sustainability dimensions such as Economic, Environmental, Social, Technological and Ethical.
