This paper explains an implementation model for a new method for Production Leveling designed for batch production system. The main structure of this model is grounded on three constructs: traditional framework for Operations Planning, Lean Manufacturing concepts for Production Leveling and case study guidelines. By combining the first and second construct, a framework for Production Leveling has been developed for batch production systems. Then, case study guidelines were applied to define an appropriate implementation sequence that includes prioritizing criteria of products and level production plan for capacity analysis. This conceptual model was applied on a Brazilian subsidiary of a multinational company. Furthermore, results evidence performance improvement and hence were approved by both managers and Production personnel. Finally, based on research limitations, researchers and practitioners can confirm the general applicability of this method by applying it in companies that share similarities in terms of batch processing operations.
