The Satisfy module within the ODS system for DPD Netherlands was successfully implemented as a solution for the automatic creation of parcel scans based on existing scans and other data in the system.
This module automatically generates new scans and sends them as GEODATA events to other DPD systems via the Budah subsystem. The module is divided into two main parts: automatic scan creation and manual bulk creation or editing of scans in the Tracy user interface.
DPD Netherlands required a solution for the automatic creation of parcel scans based on existing scans (so-called trigger scans). The challenge was to build a flexible system that would generate new scans only when specific predefined conditions were met. Additionally, it had to allow for easy configuration and management of scan creation scenarios directly through a user interface. Each scenario was to consist of a combination of rules (selected from a set of predefined filters) and a set of parameters defining the properties of the newly created scan. The resulting scans needed to be automatically distributed to other DPD systems via the Budah subsystem.
The system uses an asynchronous architecture based on message queue processing, which waits for trigger information about incoming scans. For each received scan, the system runs all relevant generators that, based on their configuration, evaluate whether one or more new scans should be created. These newly generated scans can in turn act as triggers for additional generations, creating a chain of automated events.
Scan generators are built using block-based processing, where a sequence of processing blocks is applied responsible for data loading, filtering, and scan creation. These blocks are fully configurable, allowing for easy modifications and extensions of the process according to the customer’s current needs.
As part of the initial implementation, two basic types of generators were deployed:
The user interface in the Tracy portal allows full management of generators. Users can view all existing generators in a clear table, filter them as needed, and edit, activate/deactivate, or delete them. When editing, an editor is available that visualizes the entire scan generation workflow as a sequence of processing blocks, making the processes easier to understand and modify.

The deployment of the Satisfy module brought significant improvements to the automation of parcel scan processing at DPD Netherlands.
The main advantages include:
The implementation of the Satisfy module within the ODS system for DPD Netherlands represents a modern, robust, and flexible tool for automated parcel scan creation. It is based on precisely defined requirements and leverages modern asynchronous and block-based processing, ensuring high reliability and scalability. Thanks to its intuitive user interface and configurable setup, the module is fully adaptable to the customer’s evolving needs.
