European Transport Compliance & Rules Engine
As part of a large enterprise ERP system, I developed a specialized rules engine for transportation operations across the European Union.
The module automatically determines whether a planned transportation operation complies with applicable regulations, taking into account vehicle characteristics, cargo parameters, routes, countries involved, and specific transportation conditions.
The underlying business logic was highly complex, with numerous regulatory rules, exceptions, dependencies, and combinations of operational parameters. Many of these requirements had previously been handled manually, making the process difficult to maintain and creating a significant risk of human error.
The solution transformed this complex regulatory knowledge into an automated software-based decision engine. It helped transportation teams identify potentially non-compliant operations before they were executed, significantly reducing the risk of incorrect transportation practices, regulatory violations, and costly fines.
The system was implemented as part of a proprietary ERP platform using .NET, MSSQL, WinForms and DevExpress. Due to the confidential nature of the ERP system, the source code and detailed business rules cannot be publicly disclosed.
