Applying Lean Manufacturing Principles to reduce waste and improve process in a manufacturer: A research study in Peru

Abstract

In the present scenario, lean manufacturing techniques are the most successful improvement concepts that many companies can apply in order to eliminate waste and non-value-added activities related to the manufacturing process. This paper discusses the implementation of lean manufacturing tools and an integrated framework between production planning and quality in a SME dedicated at a production of kitchen equipment. Studies of the company processes showed that the cutting and bending processes tend to create the most amount of sheet metal waste and non-value-added activities. The main objectives of the research were to standardize work, reduce waste, eliminate machine failures and develop the guidelines for a correct planning that meets quality requirements. The improvement results have shown a positive impact reducing the waste ratio and this has meant a saving of 13% in the manufacturing cost.
