Integration and business process orchestration within national DTC segments
Tasks for the formation of national DTC segments
During the formation of national DTC segments, the following tasks must be addressed:

A. Selection of an integration solution for the national transport and logistics platform that ensures connectivity with IT systems of transport modalities and involved government authorities.
B. Establishment of a trusted information space and data exchange environment within the transport and logistics sector and the national MMDC segment, based on effective orchestration of multimodal business processes.
C. Provision of secure and legally significant information exchange within the transport and logistics sector and in cross-border interaction with neighboring MMDC participating countries.

The first two tasks were addressed by the CompleteSoft expert group in 2020–2021 during the development of a project for the digitalization of intermodal freight transportation in the transport corridor between EU and EAEU countries. The proposed scheme of information interaction between transport and logistics participants within the national MMDC segment is shown in Figure 1.

At the national level, the NSLP platform should be integrated with government systems responsible for controlling and managing transport and trade flows in the country, as well as with technological systems of the main transport modalities. In addition, national MMDC segments also include such transport and logistics infrastructure elements as Border Crossing Points (BCPs), multimodal transport hubs (where cargo may be transferred from one mode of transport to another), and logistics centers/dry ports. The national level covers the core set of transport and logistics services, as well as compliance with regulatory requirements.

The local (or technological) level includes business-to-business (B2B) and business-to-government (B2G) transactions. Within this information environment, the NSLP platform provides authorization, data storage, registration of completed transactions, logistics data exchange, monitoring/tracking services, and more.
In B2B interactions, enterprises exchange information between entities within the national segment, while in B2G interactions, information for regulatory and statistical purposes is submitted/transferred to government authorities through the NSLP acting as the Single Window for the transport and logistics sector. Thus, key government institutions and transport and logistics participants at national and local levels interact through the NSLP and exchange G2B, B2G, and B2B data through authorized EDI operators or through direct integration with the platform.
This makes information exchange for multimodal transport and logistics at the national level more efficient and also ensures connectivity and interoperability of IT systems used by different transport modalities.

Cross-border information interaction with other MMDC participating countries is ensured through data pipeline modules integrated into NSLP platforms, while IT systems of transport modalities may also interact within MMDCs through direct connectivity between national modal systems of neighboring countries. Such an interaction scheme provides efficient and secure information exchange between transport and logistics participants at national and local levels and guarantees the required processing of data within the NSLP, as well as its transmission to the interstate cross-border level in standardized data set or electronic document formats. The described integration and interaction scheme for national transport and logistics platforms and modal systems as information hubs, developed with the participation of CompleteSoft experts in 2024–2025 for the digitalization of national segments of the Trans-Caspian MMDC, is shown in Figure 2.

With such an integration scheme based on national transport and logistics platforms, the task of orchestrating multimodal business processes can be effectively addressed through centralized management and processing of information flows from modal systems and services according to a predefined scenario/model of cargo transit transportation. During the digitalization of business processes, orchestration makes it possible to combine legacy systems with new digital tools, ensuring their seamless operation.

Key aspects of orchestration include:

Centralized control: There is a single “conductor” (orchestrator) that understands the entire process algorithm, invokes the required services, waits for their responses, and determines the next step.

Service-oriented architecture (SOA): The process is built on existing applications and microservices, which the orchestrator combines into process chains.

State management: The orchestrator tracks the current stage of process execution, which is critically important for long-running transactions.

Flexibility: Allows rapid modification of process logic in a single place (within the process model) without rewriting the code of individual services.
