Abstract
The GPICS (Generic Physical Internet Case Study) framework has been developed within the ICONET (New ICT infrastructure and reference architecture to support Operations in future PI Logistics NETworks) project. It is a methodology for designing and evaluating supply networks through PI. GPICS is a conceptual framework that is generated as an abstraction of different Living Lab cases and generic industrial scenarios. It is formed based on six interrelated dimensions. GPICS modelling is designed to allow the composition of a generic PI network through reusable modelling components and rules, via appropriate configuration, these components can represent different types of supply chain flows. The six interrelated dimensions range from the necessary modelling components and base configuration rules (Modelling Kit) to the scenario definition/parameterization capabilities (based on operational rules, business models and vertical and horizontal collaboration strategies between the different roles in the supply chain), including Master Data Sets, that concern and are relevant for a Geographical Area within the EU. As mentioned above, the GPICS also includes a set of benchmark KPIs for the assessment of different PI scenarios, based on a different combination of the configuration capabilities of these scenarios. The network is represented by using a virtual simulation model. A multi-agent simulation model is used to create a digital twin of the supply network, utilizing GPICS main components and integrated with ICONET’s PI services. The virtual model contains a general representation of the main nodes and their interconnections. It creates a representation of the main flows of freights in a PI network. It can include transports from different companies, with different restrictions. The simulation model developed is a tool that helps companies to visualize how the movement of products over a PI network can be, including flows from other companies. The virtual models are used to quantify the impact of the different services. Economic (transport and handling costs), operational (reducing lead time) and environmental (CO2 emissions) indicators have been obtained in different living labs. The description of two use cases developed in the project is included.
