摘要:In today’s competitive market environment, companies are continuously forced to improve their warehousing operations. To meet high performance goals, tools must be developed to improve efficiency in every aspect of warehousing function. In this paper, we propose a new approach to improve the performance of the warehousing function based on Maturity model, which may better identify, explain, assess and improve this critical function in a supply chain. The aim of this article is to validate the model developed by a case study in a Moroccan company by demonstrating its capacity of assessing the maturity of warehousing function and whether it can develop an improvement roadmap.
