Definition

This entry reviews the evolution from Digital Twins (DT) to Predictive Digital Twins (PDT) and Digital Triplets (DTr), culminating in Predictive Digital Ecosystems, which focus on economic and financial decision-making. It discusses historical developments, technical foundations, practical applications, ethical and regulatory challenges, and future directions. The overview integrates mature knowledge from engineering, data science, and economic domains to provide a structured reference framework for understanding and deploying Predictive Digital Ecosystems.

1. History

The emergence of Digital Twins (DTs) represents a transformative development in the application of digital technologies across various sectors, including manufacturing, engineering, healthcare, and increasingly, economic, and financial decision-making [1,2,3,4,5,6]. A DT is traditionally understood as a real-time, dynamic digital representation of a physical asset, system, or process [2]. Initially developed to enhance monitoring and maintenance operations by replicating physical objects within a virtual environment, DTs evolved considerably with advances in Internet of Things (IoT), Big Data, artificial intelligence (AI), and cloud computing technologies [2,7,8]. With the integration of predictive modeling, DTs gave rise to Predictive Digital Twins (PDTs), which go beyond descriptive capabilities to offer foresight into future system behaviors based on current and historical data [9,10]. The increasing complexity and interdependence of systems have led to the concept of DTr [11,12,13], where multiple PDTs are interconnected within a holistic framework known as a Predictive Digital Ecosystem (PDE) [9,14]. These interconnected systems provide comprehensive predictive analytics capabilities and support proactive decision-making processes, particularly in the highly dynamic and interconnected fields of economics and finance [15]. This entry provides a comprehensive review of the development, conceptual foundations, technological infrastructures, applications, ethical considerations, and future directions of DTs, PDTs, and DTrs within the context of Predictive Digital Ecosystems.

The conceptual roots of Digital Twins can be traced back to the early simulation models developed for aerospace engineering [16,17,18]. The idea matured significantly during NASA’s Apollo program in the 1960s, where exact physical replicas of spacecraft were maintained on Earth to simulate and troubleshoot conditions encountered during missions [18,19]. However, it was not until 2005 that Dr. Michael Grieves formally introduced the term “Digital Twin” in the context of Product Lifecycle Management (PLM) [20,21]. The original framework proposed the integration of physical products, virtual products, and the connections between them to enable enhanced design, manufacturing, and operational processes. The subsequent development of IoT technologies provided the infrastructure necessary for real-time data flow between the physical and digital realms, making the realization of true Digital Twins feasible. Over time, the role of DTs expanded from static models to dynamic, real-time systems capable of supporting complex decision-making processes [22,23]. Integrating predictive analytics methodologies, including machine learning algorithms and advanced simulation techniques, further evolved DTs into Predictive Digital Twins, enabling organizations to anticipate future states and optimize operational and strategic responses [24]. The growing interconnectedness of economic activities and the increasing need for holistic system representations have prompted the emergence of DTrs and PDEs, which conceptualize entire ecosystems of interconnected predictive models capable of collaborative learning, adaptation, and decision-making.

A key trajectory in digital transformation involves the transition from Digital Twins (DTs) to Predictive Digital Ecosystems (PDEs), which encapsulate real-time situational awareness, machine learning foresight, and ecosystemic optimization. DTs initially emerged in industrial settings as digital replicas of physical assets, enabling diagnostics and performance monitoring.

To further clarify the architectural variety of Digital Twins and how this progression informs PDEs,

Table 1. Typology of Digital Twin architectures: from simulation to autonomy.

Architecture Type	Defining Characteristics	Data Integration	Autonomy Level	Key Use Cases
Model-Driven DT	Based on physics-based or engineering simulation models	Low	Low	Aerospace simulation, material stress testing
Data-Driven DT	Empirical modeling via sensor streams, Machine Learning (ML) pattern recognition	High	Medium	Manufacturing, predictive maintenance
Hybrid DT	Integrates data streams with pre-existing analytical or mechanistic models	Medium–High	Medium–High	Healthcare, urban traffic control, fintech
Cognitive DT/DTr	Self-learning systems with real-time environmental adaptation	Very High	High	Autonomous vehicles, smart grids, ESG compliance

presents a typology of DT architectures. The typology identifies four major categories—Basic Replicative DTs, Monitoring Twins, Predictive Twins, and autonomous PDEs—each with increasing levels of integration, real-time responsiveness, and decision-making autonomy.

This typology elucidates the transformation from object-centric monitoring to ecosystemic prediction and governance. Basic DTs rely on batch data and serve as visual diagnostics tools. Monitoring Twins incorporate real-time telemetry but remain reactive. Predictive Twins, by contrast, leverage machine learning for forecasting system states. Finally, autonomous PDEs represent the apex of architectural complexity, integrating decentralized AI, federated learning, and blockchain-enabled traceability to support autonomous optimization across sectors like urban mobility, finance, and supply chains.

2. Conceptual Framework and Applications

DT, PDT, and DTrs form a conceptual continuum of increasing complexity and capability [23,24,25,26]. A Digital Twin is a digital replica of a physical entity, continuously updated through bidirectional data flows that reflect the real-time state of the asset or system [27]. It typically incorporates a physical model, a virtual model, and a set of data exchange protocols that ensure synchronization between the two. Predictive Digital Twins extend this model by incorporating predictive analytics, enabling the simulation of future scenarios and optimizing processes before issues arise [9,28,29]. They are characterized by the ability to forecast potential failures, recommend preventive measures, and optimize performance dynamically. The concept of DTrs advances this further by interlinking multiple PDTs across different domains or system components, creating a Predictive Digital Ecosystem [11]. PDEs are defined by their ability to manage, analyze, and simulate complex interdependent systems, supporting decision-making across entire organizations or economic sectors. A PDE integrates data streams, predictive models, and decision-support mechanisms into a unified environment, fostering collaboration between digital agents representing various physical or organizational entities, as shown in

.

DTs, PDTs, and DTrs are realized through the convergence of several key technologies [24]. IoT devices and networks provide the sensory inputs necessary for real-time monitoring of physical systems, capturing a wide range of operational data, including environmental conditions, performance metrics, and system statuses. Cloud computing offers the scalable computational and storage infrastructure needed to process and manage the massive volumes of data generated by these systems. AI and machine learning algorithms are critical in analyzing data, identifying patterns, forecasting future conditions, and optimizing decision-making processes [13,30]. Big Data analytics frameworks enable the handling of high-volume, high-velocity, and high-variety data inputs, ensuring that insights can be derived promptly and effectively [37]. Blockchain technologies contribute to ensuring the integrity, security, and traceability of data transactions within PDEs, addressing critical concerns related to trust and compliance [31,35]. Additionally, advances in edge computing enable real-time analytics that are closer to the source of data generation, reducing latency and enhancing the responsiveness of predictive models. Collectively, these technologies form the backbone of modern Predictive Digital Ecosystems, allowing for the seamless integration of physical and digital worlds, as shown in

Applications in Economic and Financial Decision-Making

The application of PDEs in economic and financial decision-making has introduced a paradigm shift in how organizations model, predict, and respond to market dynamics. DTrs are employed in the financial services sector for risk management, fraud detection, asset management, and regulatory compliance [11,12,13,32,33,36,38,39,40,41,42]. Predictive models enable institutions to simulate market conditions, forecast asset performance, detect anomalies in transaction patterns indicative of fraudulent activities, and ensure adherence to evolving regulatory standards [43]. For example, the European Central Bank (ECB) has explored the deployment of AI-enhanced Digital Twin models to simulate monetary policy transmissions and stress-test banking systems under various macroeconomic scenarios. Similarly, large insurance groups such as AXA (a global insurance and asset management firm headquartered in France) and Munich Re are developing Predictive Digital Ecosystems to recalibrate risk models in response to climate-related catastrophe data dynamically. In the logistics domain, Maersk has implemented Digital Twin infrastructure across its global operations, integrating real-time vessel telemetry and port conditions into PDEs to optimize routing, reduce fuel consumption, and forecast disruptions. In supply chain management, PDEs are utilized to optimize logistics operations, forecast demand, manage inventory, and provide supply network resilience against disruptions [44]. By continuously monitoring and predicting supply chain dynamics, organizations can proactively adjust operations to mitigate risks and capitalize on emerging opportunities. DTrs contribute to infrastructure management, resource allocation, and sustainability planning in smart city initiatives [45,46,47,48]. They enable city planners to simulate the impact of policy decisions on traffic patterns, energy consumption, and environmental sustainability, facilitating data-driven governance [49,50]. Public sector examples include Singapore’s “Virtual Singapore” platform, a comprehensive urban Digital Twin that facilitates predictive planning in traffic flow, energy needs, and emergency preparedness. In the EU, several municipalities are collaborating through the “Living-in.EU” initiative to standardize city-level PDEs for citizen-centric services, integrating mobility, environmental, and socio-economic data into real-time governance dashboards. Moreover, in broader economic modeling, PDEs help policymakers and analysts simulate the impacts of fiscal and monetary policies, project economic trends, and design interventions that promote stability and growth.

, captures the conceptual and technological progression from early simulation models to fully integrated Predictive Digital Ecosystems. It illustrates the transition from single-entity monitoring (DTs) to dynamic forecasting (PDTs), and finally to systemic modeling and collaborative decision-making (DTrs/PDEs). Technological layers, including IoT, AI, blockchain, and edge computing, underlie the capabilities and applications of each stage.

3. Ethical, Legal, and Regulatory Considerations

The typologies of Digital Twin systems—ranging from early descriptive models to emerging predictive ecosystems—illustrate a coherent technological and conceptual evolution. Each typology encapsulates a distinct developmental stage in the lifecycle of cyber-physical systems, expanding in both analytical depth and systemic interconnectivity. This continuum begins with conventional Digital Twins (DTs), evolves through Predictive Digital Twins (PDTs), advances with Digital Triplets (DTrs), and culminates in the Predictive Digital Ecosystem (PDE), which integrates distributed intelligence, real-time learning, and autonomous decision-making capabilities across domains.

The increasing adoption of Digital Twins, Predictive Digital Twins, and Predictive Digital Ecosystems across economic and financial domains raises important ethical, legal, and regulatory considerations. These concerns must be addressed systematically to ensure the responsible development, deployment, and governance of predictive digital technologies.

A primary ethical concern relates to data privacy and confidentiality. Predictive Digital Ecosystems rely heavily on collecting, aggregating, and analyzing large volumes of sensitive personal, financial, and organizational data [57,58]. Ensuring the privacy of individuals and institutions requires robust data protection frameworks that align with international regulations, such as the General Data Protection Regulation (GDPR) and emerging national data privacy laws [53,59,60]. Data anonymization, encryption, and access controls must be embedded within PDE architectures to prevent misuse and unauthorized access [50,54,61].

Another significant challenge is the potential for algorithmic bias and unfairness within predictive models. Biases in training data or model design can lead to discriminatory outcomes, particularly in critical areas such as credit scoring, insurance underwriting, and hiring practices. To mitigate such risks, it is essential to implement transparent model development processes, conduct regular audits to ensure fairness, and apply corrective techniques to minimize disparate impacts [62].

Transparency and explainability are vital for fostering trust in predictive decision-making systems. Complex AI and machine learning models often function as “black boxes,” making it difficult for stakeholders to understand how predictions are generated. In economic and financial contexts, where accountability is paramount, developing explainable artificial intelligence (XAI) frameworks must provide clear, comprehensible rationales for predictive outcomes [63,64].

Another critical area is regulatory compliance. PDEs operating in highly regulated sectors, such as banking, insurance, and capital markets, must adhere to stringent standards for data handling, model validation, reporting, and operational resilience. Regulatory bodies increasingly emphasize the need for transparency, stress testing of AI models, and demonstrable governance structures to ensure that predictive technologies do not introduce systemic risks [51,55,65].

Intellectual property (IP) rights introduce additional complexity. As predictive models, datasets, and insights become increasingly valuable assets, clear legal definitions are required regarding the ownership, licensing, and use of Digital Twins and their derivatives. Failure to establish clear IP agreements may result in disputes over proprietary technologies and competitive advantages [66,67,68].

Beyond technical and legal issues, broader societal and ethical impacts must be considered. The widespread deployment of predictive digital systems has implications for employment, economic inequality, and democratic processes. Automation of decision-making could exacerbate existing disparities if not carefully managed, and the concentration of predictive capabilities within a few powerful entities may challenge competitive and social equity norms [69,70,71].

Finally, global governance frameworks for predictive technologies remain underdeveloped [34,72]. Coordination among international regulatory bodies, technology developers, and civil society organizations will be essential to establish universally accepted ethical principles and operational standards for PDEs. Without such coordination, fragmented regulatory landscapes could impede innovation while failing to adequately protect public interests [34,56].

The ethical, legal, and regulatory landscape surrounding Predictive Digital Ecosystems is complex and evolving. Addressing these challenges requires a multidisciplinary approach, combining technological safeguards, legal reforms, ethical guidelines, and public engagement to ensure that the development of predictive digital technologies supports fair, transparent, and socially beneficial outcomes, as shown in

4. Current Challenges

Despite the significant advancements and transformative potential of DT, PDT, and PDE, several critical challenges impede their widespread adoption and effective deployment. One of the foremost issues is interoperability [73,74]. The lack of standardized frameworks, protocols, and data formats across industries, platforms, and technological providers results in substantial barriers to integrating heterogeneous Digital Twin systems [52]. Without common ontologies and interoperable architectures, the seamless interaction between various PDTs within a DT ecosystem becomes increasingly difficult, limiting the realization of system-wide predictive capabilities.

Another major challenge lies in data management and quality assurance [75]. The effectiveness of predictive digital models inherently depends on the quality, consistency, and completeness of the data they ingest. Inaccurate, outdated, or biased data can lead to erroneous predictions, undermining the reliability and credibility of PDEs. Furthermore, model drift, where predictive models lose accuracy over time due to underlying system dynamics or external environment changes, poses ongoing risks to system performance and necessitates continual model monitoring, validation, and recalibration [75].

Computational complexity and scalability represent additional hurdles [76]. The real-time processing of massive, high-dimensional datasets and the need for dynamic simulation and predictive modeling demands considerable computational power and specialized infrastructure [50,54,77,78,79]. These requirements are especially burdensome for small and medium-sized enterprises (SMEs) and public sector organizations, which often operate under resource constraints, rigid procurement cycles, and limited digital maturity. The capital expenditures associated with PDE deployment—including IoT infrastructure, AI training, cybersecurity, and cloud services—may not be economically justifiable without a clear short-term return on investment. Furthermore, many SMEs lack in-house expertise in data science or systems integration, rendering them dependent on costly external vendors or limited-functionality off-the-shelf solutions.

Public sector agencies face similar feasibility constraints. Budgetary limitations, fragmented legacy systems, and complex regulatory oversight can delay PDE implementation, even when long-term societal benefits are evident. Consequently, there is a pressing need for affordable, scalable, and modular PDE architectures—ideally supported by open-source frameworks and inter-municipal consortia that promote shared digital infrastructure and collective expertise. This requirement may be particularly challenging for small and medium-sized enterprises (SMEs) or public sector entities with limited resources. Additionally, cybersecurity threats, such as data breaches, ransomware attacks, and adversarial machine learning techniques, could compromise the integrity and confidentiality of PDEs, further complicating their deployment in sensitive economic and financial contexts [80,81].

Organizational and cultural resistance is another critical factor that can hinder the adoption of Predictive Digital Ecosystems [82]. Transitioning to a data-driven, predictive decision-making model often requires significant changes in corporate culture, leadership approaches, operational workflows, and employee competencies [83]. Organizations must invest in training, change management, and governance structures to facilitate this transition effectively.

Lastly, as mentioned, ethical and regulatory considerations present ongoing challenges. Ensuring that PDEs operate transparently, fairly, and in compliance with relevant data protection and financial regulations is essential to build and maintain stakeholder trust [84,85,86]. The absence of clear legal standards for AI-driven predictive decision-making, particularly regarding accountability for automated outcomes, remains a substantial barrier that necessitates coordinated efforts among technologists, policymakers, and regulatory bodies.

Addressing economic feasibility and democratizing access to PDE capabilities will be essential for ensuring that their transformative potential does not remain limited to large multinational corporations or tech-centric states. Governments and international bodies could consider developing targeted funding schemes, regulatory sandboxes, and public-private partnerships to encourage experimentation and safe adoption among underserved sectors.

Delivering these multifaceted challenges is crucial for the sustainable development, deployment, and societal acceptance of PDEs. Continued research, cross-sector collaboration, and regulatory innovation will be crucial to overcoming these barriers and fully harnessing the transformative potential of DTrs in economic and financial decision-making.

5. Future Directions

The future of PDEs is poised for significant advancements driven by technological innovation, regulatory evolution, and growing societal demands for transparency and accountability. Developments in quantum computing, such as those by Rigetti Computing Inc., D-Wave Quantum, and IONQ Inc., among others, can significantly enhance the processing capabilities of predictive models, enabling more accurate and comprehensive simulations of complex systems [82,83]. Advances in federated learning and privacy-preserving machine learning techniques will facilitate collaborative modeling without compromising data confidentiality. The emergence of decentralized and self-organizing PDEs, powered by blockchain and edge computing technologies, may enable more resilient, scalable, and autonomous digital ecosystems. Standardization initiatives, such as those led by the International Organization for Standardization (ISO) and industry consortia, will promote interoperability and facilitate broader adoption. Research into the socio-economic impacts of PDEs will guide the development of frameworks that ensure their ethical and equitable deployment. As the complexity and interconnectedness of global economic systems continue to grow, PDEs will play an increasingly vital role in enabling adaptive, resilient, and sustainable decision-making across sectors.

Moreover, while the expansion of Digital Twins into predictive and autonomous domains suggests a positive technological trajectory, this evolution is not without complications. The deployment of PDEs in high-stakes environments, such as public policy, finance, and urban governance, introduces epistemological challenges that extend beyond technical design. Unlike traditional simulations, which are bounded by fixed parameters, PDEs often operate within open-ended systems, where the future is continuously predicted, shaped, and acted upon. This process, sometimes referred to as anticipatory governance, may subtly reinforce feedback loops that lead to the normalization of prediction-driven interventions, raising questions about the autonomy of human decision-making. As Ai [55] points out, responsible Digital Twins must grapple with the implications of recursive system design and algorithmic agency.

The need to retain interpretability and participatory oversight becomes especially urgent in settings where predictive mechanisms replace deliberative ones, potentially narrowing the scope of alternatives considered. From a regulatory standpoint, the distinction between predictive suggestion and prescriptive automation remains largely undefined, creating a grey zone in accountability structures. This blurring of predictive and normative functions warrants further inquiry, particularly as Digital Triplets and ecosystem-scale twins become embedded in critical societal infrastructures.

6. Conclusions and Prospects

The evolution from Digital Twins to Predictive Digital Twins and, ultimately, to Digital Triplets embedded within Predictive Digital Ecosystems has fundamentally reshaped economic and financial decision-making approaches. DTs originally enabled the real-time replication and monitoring of physical systems, while Predictive DTs advanced this capability by incorporating forecasting, simulation, and proactive optimization strategies. Digital Triplets extend this paradigm by connecting multiple PDTs, and facilitating system-wide modeling, collaborative forecasting, and comprehensive decision support.

Predictive Digital Ecosystems integrate diverse data sources, predictive models, and decision-making processes, allowing organizations to navigate complex, dynamic environments with greater agility, foresight, and resilience. Their growing applications across financial services, supply chain management, and urban governance demonstrate their potential to enhance operational efficiency, strategic planning, and systemic sustainability.

However, developing and deploying PDEs introduce significant challenges, including the need for robust data privacy protections, mitigation of algorithmic biases, regulatory compliance, and transparent and ethical governance. Addressing these concerns will be crucial to maintaining trust and maximizing the societal benefits of these technologies.

Future advancements in edge computing, blockchain, AI, and quantum computing are expected to further enhance PDEs’ capabilities and scalability. The maturation of interoperability standards and ethical frameworks will also be vital for broader adoption and sustainable development. As Predictive Digital Ecosystems become increasingly integral to modern economic and financial infrastructures, their continued evolution will enable informed, transparent, and resilient decision-making in an increasingly complex global landscape.
