4PLmodeller

4PLmodeller is a software platform for modelling and analyzing fourth-party logistics networks. It supports planning, optimization, and evaluation of 4PL arrangements involving multiple service providers, shippers, carriers, and warehouses. It helps users compare configurations and predict performance under different scenarios.

Key features include a graph-based network editor to define facilities, nodes, and transport links; data import from ERP, WMS, transport systems; cost and SLA modelling; optimization engines for routing, inventory, and capacity planning; scenario comparison with pre/post analysis; visualization dashboards; reporting; and interoperability via APIs and standard data formats.

Data model encompasses facilities, distribution centers, suppliers, carriers, service providers, service levels, costs (transport, storage, handling, penalties), and SLAs (delivery windows, reliability). The typical workflow includes importing data, modelling the network, configuring costs and SLAs, formulating optimization problems, running analyses, reviewing results, and generating reports.

Architecture is modular, available as web-based or desktop software, and supports role-based access, security and audit trails, with options to operate on-premises or in the cloud. It integrates with ERP, WMS, and TMS systems and provides import/export in CSV, JSON, and XML. The tool supports scenario management and change tracking to compare alternative network configurations over time.

Use and limitations: 4PLmodeller is used by logistics planners and consultants to evaluate 4PL configurations, identify cost savings, and assess risk. Limitations include dependence on data quality, simplifications inherent in modelling complex real-world contracts, and potential computational complexity for large networks. Availability is marketed as a commercial product by multiple vendors.
