Production Leveling or Heijunka: A Bibliometric Study

Heijunka is the most basic concept of Toyota Production System and yet the one that has received the least attention in the literature. Production Levelling, Production Smoothing and Mixed Model Production are all different designations of the same concept of Heijunka which can be defined as distributing the production of dissimilar parts/products evenly throughout an interval of time (day, week, month). This paper aims to shed the light on this concept by conducting a Bibliometric Study. It will help us offer a comprehensive view of Heijunka by finding out the frequency of the articles and the most pertinent journals that talked about it, the keywords that have been frequently mentioned and the trends in research.
