          Abstract – Over the years, with the migration of organizations towards the concepts of logistics 4.0, a paradigm shift was
          necessary to guarantee logistics ef iciency. The challenge is to dynamically cope in real time with vast number of shipments
          and destinations, which need to be realigned both with a determined lead time and with a  inite of available resources. Al‑
          though a number of standards have already been adopted for the management of transport and logistics operations, tak‑
          ing advantage, for instance, of Decision Support Systems and Geographic Information Systems, new models are required for
          achieving effective handling of the dynamic logistics environment that is shaped today. In this paper, an integrated logistics
          framework addressing the previous challenges is presented, for the  irst time, as a result of the activities of the H2020 COG‑LO
          project. This novel approach exploits Social Internet of Things (SIoT) and the digital twins technique to realize the concept
          of the Cognitive Logistics Object (CLO). A CLO is de ined as an entity that is augmented with cognitive capabilities, it is au‑
          tonomous, and bears social‑like capabilities, which enable the formulation of ad hoc communities for negotiating optimal
          solutions in logistics operations.
