Towards Autonomous Supply Chains: Defining Characteristics, Conceptual Framework, and Autonomy Levels

Core Concepts

Autonomous supply chains (ASCs) are self-governing supply chains built upon intelligence and automation, where key structural entities can make and enforce decisions with little or no human intervention.

Abstract

This paper presents a formal definition of autonomous supply chains (ASCs) and describes their defining characteristics. It introduces a five-layer conceptual model, called the MIISI model, for constructing ASC systems. The model comprises the following layers: Instrumentation, Standardisation, Interconnection, Integration, and Manifestation.

The paper also introduces a seven-level supply chain autonomy reference model, called the Supply Chain Autonomy Levels (SCALs), which delineates a trajectory towards achieving full supply chain autonomy. The SCAL model ranges from Level 0 (fully manual) to Level 6 (fully autonomous), with the lower levels focused on automation and the higher levels on autonomisation.

The authors use a case study on the meat supply chain to demonstrate an initial ASC implementation based on the MIISI conceptual model. This work aims to stimulate further research, both theoretical and technical, and contribute to the continual evolution of ASCs.

Deeper Inquiries

How can the MIISI model and SCAL reference framework be extended to incorporate emerging technologies like blockchain and quantum computing?

The MIISI model and SCAL reference framework can be significantly enhanced by integrating emerging technologies such as blockchain and quantum computing, which offer unique capabilities that align with the goals of autonomous supply chains (ASCs).

Integration of Blockchain Technology:

Transparency and Traceability: Blockchain can be integrated into the MIISI model, particularly within the Standardisation and Interconnection layers. By establishing a decentralized ledger, blockchain enhances data integrity and traceability across the supply chain. This ensures that all transactions are recorded transparently, allowing stakeholders to verify the authenticity of products and transactions in real-time.
Smart Contracts: The use of smart contracts can automate agreements between supply chain entities, facilitating seamless execution of transactions without the need for intermediaries. This aligns with the Automation characteristic of the MIISI model, enabling more efficient and reliable operations.
Data Security: Blockchain's inherent security features can address concerns related to data privacy and security, particularly in the Standardisation layer where data exchange protocols are established. This can help mitigate risks associated with data breaches and unauthorized access.

Incorporation of Quantum Computing:

Enhanced Decision-Making: Quantum computing can be integrated into the Manifestation layer of the MIISI model, where complex decision-making processes occur. Quantum algorithms can process vast amounts of data at unprecedented speeds, enabling real-time optimization of supply chain operations, such as demand forecasting and inventory management.
Complex Problem Solving: Quantum computing can tackle NP-hard problems that are common in supply chain logistics, such as route optimization and resource allocation. This capability can elevate the autonomy levels defined in the SCAL framework, particularly in the higher levels (L5 and L6), where self-learning and self-decision-making are critical.
Simulation and Modeling: Quantum computing can enhance the simulation capabilities of supply chains, allowing for more accurate modeling of complex supply chain scenarios. This can improve risk management and contingency planning, essential for maintaining resilience in turbulent environments.

By incorporating blockchain and quantum computing into the MIISI model and SCAL framework, organizations can achieve a more robust and resilient autonomous supply chain that leverages advanced technologies to enhance efficiency, transparency, and decision-making capabilities.

What are the potential challenges and limitations in implementing fully autonomous supply chains, and how can they be addressed?

Implementing fully autonomous supply chains (ASCs) presents several challenges and limitations that organizations must navigate to achieve successful deployment.

Technological Barriers:

Integration Complexity: The integration of various technologies (AI, IoT, blockchain, etc.) into existing supply chain systems can be complex and resource-intensive. Organizations may face difficulties in ensuring interoperability among diverse systems and platforms.
