**6. Conclusion**

This project aim to show the importance of new technologies and sustainability in the digital transformation of a hospital in the Covid pandemic context. Considering the need to improve hospital logistics with the worsening of it, with the presence of the COVID pandemic, the article presents a generic model of optimization of hospital logistics, where first was presented a literature review containing the new technologies and tools of industry 4.0, logistics 4.0, Lean manufacturing and lean healthcare. After this step, the concepts and methods applied in the development of the project and containing the steps of a global approach have been presented. Finally, the decision aided tool designed to facilitate the logistics optimization process has been presented, containing its functionalities and architecture.

Many of the improvements presented in this article are already applied and consolidated as efficient technologies in the industrial field, but in the healthcare field it is still possible to reuse them to cause a great impact. Today, at such a critical moment for the healthcare field, the need to facilitate the optimization of hospital logistics has become even more relevant. As a result, the tools presented in this article will allow hospitals, doctors, nurses and patients to benefit from the results, thus reducing costs and increasing the time and quality of care.

The opportunity to validate concepts elaborated on two hospital transformations is an advantage for improving the methodology and tools that are proposed in this paper. Sustainability aspects in this healthcare logistics 4.0 concepts implementation concern social and societal dimensions but not sufficiently environmental transformation. This transformation such as waste valorization and reverse logistics, circular economy will be integrated in the study after the validation of the decision tool being developed.
