This research has proposed a tentative design of information flows on PI embed three PI components: (1) modular containers, (2) open interface web, and (3) global protocols. Through the design, this research has identified potentials of the primary PI elements to resolve current issues in freight logistics (i.e., inefficient space utilization on loading units and lack of their visibility). In-line with trends of the maritime logistics, PI ports in the design exploit the major PI elements in one of the value-added services, repositioning operation. In the context of PI ports, requirements on the three PI components have been elicited and reflected in the conceptual design. The adjusted RAMI 4.0 has been applied to visualize not only information flows in PI ports but also required logistics entities, activities and interactions in Track and Trace (T&T) system, and moreover operational processes. As a result, the conceptual model proposes requirements for PI ports along with potentials of each PI element.
