Application of heijunka leveling in a medical devices company
Keywords:Lean Production, Heijunka, Leveling, SME’s, Unstable processes
AbstractOne of the great challenges for companies is to satisfy their customers by delivering products on the dates and quantities required, while keeping low inventories levels as well as reduced lead times. In order to achieve this goal, the Lean Manufacturing with heijunka as a foundation, based on capacity leveling according to demand and is expected to reduce inventories and lead-time levels. In this sense, the objective of this work was to study the application of the heijunka leveling tool in a small medical devices company, characterized by low volume production and unstable demand. This study was based on an exploratory bibliographical survey with the objective of identifying existing studies on the subject; Carried out a case study with application of the tool and described its application in this company as well as its consequences. The results show the need to adapt it to the situation of each company, which involves determining an ideal level of leveling, so that it is possible to obtain the advantages that this tool provides.
