This governance-first approach improves trust, accountability, and enterprise readiness while reducing operational risk. 4.6 Learning Agent The Learning Agent enables continuous adaptation and longterm system improvement. Following action execution, it collects performance feedback and compares actual outcomes with predicted results to refine future recommendations. Key monitoring areas include: • Revenue Outcomes • Conversion Performance • Margin Realization • Negotiation Success Rates © 2026 The Author(s). Published by IJCOPE Journal.

Its inclusion transforms BazaarAI from a static decision-support tool into a self-improving revenue decision platform. 4.7 Consensus Mechanism The Consensus Mechanism serves as the central coordination component of the multi-agent framework and is a key contribution of BazaarAI. Enterprise objectives often conflict with one another. For example, discounting may increase conversions but reduce profitability, while strict margin controls may limit customer acquisition. Instead of optimizing a single objective, BazaarAI aggregates recommendations from multiple specialized agents and evaluates them through a collaborative decision process. Each agent contributes: • Recommended Action • Confidence Score • Expected Business Impact • Supporting Evidence • Risk Assessment The Consensus Mechanism combines these inputs to identify actions that best balance customer satisfaction, profitability, revenue growth, inventory utilization, and governance compliance. A conceptual utility function is defined as: U = w₁R + w₂M + w₃C + w₄I + w₅L where: R = Expected Revenue Impact M = Margin Preservation C = Conversion Probability I = Inventory Health L = Customer Lifetime Value The weighting factors are determined according to organizational priorities and strategic objectives.Through this collaborative optimization process V. Governance-Aware Decision Engine The Governance-Aware Decision Engine acts as the control layer of BazaarAI, ensuring that all revenue decisions comply with organizational policies, profitability requirements, and operational constraints. Rather than treating governance as a post-processing step, BazaarAI embeds governance directly into the decision-making process. This governance-centric approach enables autonomous yet accountable optimization while maintaining transparency, consistency, and enterprise trust.

  • decision-making, explainable a The major contributions of this paper are: • A unified multi-agent architecture integrating customer, pricing, revenue, and opportunity intelligence. • A governance-aware decision framework that validates actions against business constraints. • An explainable recommendation mechanism that improves transparency and trust. • A collaborative agent-based approach for balancing revenue, margin, customer experience, and inventory objectives. • An enterprise-scale Revenue Decision Operating System learning and autonomous revenue supporting continuous optimization. 1.1 Background The rapid digitalization of commerce has transformed how organizations manage pricing, customer engagement, and revenue generation. Modern enterprises operate in competitive environments where pricing decisions must adapt to customer behavior, competitor actions, market conditions, inventory levels, and business objectives. As organizations generate increasing volumes of data, there is a growing need for intelligent systems that can convert this information into actionable business decisions. Traditional pricing approaches rely on static rules and predefined discount structures. While simple to implement, these methods often fail to respond effectively to dynamic market conditions, resulting in revenue leakage, excessive discounting, missed opportunities, and inefficient resource utilization. To overcome these limitations, increasingly adopt data-driven pricing and organizations revenue management artificial solutions powered by intelligence, machine learning, and predictive analytics. Recent advances in enterprise AI have led to the development of customer intelligence platforms, dynamic pricing engines, revenue recommendation systems, frameworks. Customer intelligence systems analyze behavior and preferences, pricing engines optimize prices based on market conditions, and revenue intelligence platforms support these forecasting and performance monitoring. However, technologies are typically deployed as independent systems with limited coordination. The emergence of multi-agent AI offers new possibilities for enterprise decision intelligence. Specialized agents can collaborate while focusing on distinct business objectives, enabling the integration of customer intelligence, pricing revenue optimization, intelligence, governance, and decision support within a unified framework.

  • Several extensions merit investigation: • Temporal, directed, and adaptive topologies. Extending the framework to time-varying adjacency and Bwrite matrices A(t) and B(t) would capture the dynamic rewiring inherent in agent swarms where new tools are registered, agents are spawned, or communication patterns shift at runtime. Furthermore, decomposing the symmetric bipartite matrix B into directional matrices ( Bread ) would enable the modeling of asymmetric access controls (e.g., read- only vs. write-only tool permissions). This introduces a weighted, directed spectral problem that may require numerical rather than analytical treatment. Continuous-time coupled formulations ODEs (Paré and Beck 2020) could complement our discrete-time MMCA in capturing dynamic permission changes over time. using • Heterogeneous transmission rates. Replacing scalar transmission rates with edge-specific parameters (e.g., βA ik ) would allow modeling of varying tool trust levels and agent privilege hierarchies. ij and βB • Game-theoretic attacker models.

  • Based on the empirical findings and deployment analysis presented in this study, several critical and actionable recommendations are proposed for engineers and system architects intending to implement production-grade centralized Agent-to-Agent (A2A) negotiation orchestration systems. First, the enforcement of a zero-trust security architecture must be established from the outset as a foundational requirement. This includes the deployment of SPIFFE/SPIRE-based workload identity frameworks utilizing short-lived X.509 Secure Verifiable Identity Documents (SVIDs), combined with mutual Transport Layer Security (mTLS) enforced through service meshes such as Istio or Linkerd, with a strict 24-hour certificate rotation policy. Furthermore, all directive bundles must be cryptographically signed using HMAC-SHA256, and any unsigned or unverifiable directives must be categorically rejected. This requirement is substantiated by ablation results demonstrating a drastic decline in security effectiveness—from 95% to 51%—when cybersecurity controls are removed under adversarial conditions. Second, robust database persistence configurations are essential to ensure system reliability and recoverability.

  • Several promising directions remain for extending the Puppeteer Pattern: • Adaptive Hybrid Architectures: Dynamic arbitration mechanisms that adaptively shift the locus of control based on real-time environmental conditions (Renting et al., 2020). • Federated and Hierarchical Deployments: Research on optimal cluster sizing, inter-tier protocols, and fault-tolerance for N > 50,000 agent populations (Hasan et al., 2024; Moore, 2025). • Learning-Based Agent Integration: How a central Puppeteer can effectively fine-tune or reward- shape decentralized learning agents and ensure interpretability of hierarchical decisions. • Adversarial Robustness: Formal performance guarantees for non-cooperative and deceptive agent behaviors in high-frequency settings. • Domain Application: Decentralized energy markets (Pinto et al., 2018), autonomous supply chain management (Bastos et al., 2023), and telecommunications bandwidth allocation.

  • First formalized in the Hearsay-II speech understanding system [2] and generalized by Hayes-Roth [3] and Nii [4], blackboard ar- chitectures organize problem solving around a shared global data structure (“the blackboard”) that is updated by independent Knowl- edge Sources (KS). A control component monitors blackboard state and opportunistically activates KS modules whose preconditions are satisfied. While this approach offers flexibility, the resulting execution order can be difficult to predict and debug in operational environments. Recent LLM multi-agent frameworks revisit cooper- ative problem solving but largely through message-passing rather than shared state [6][7][8][9][10][11]; two recent works revisit the blackboard model directly [12][13] but neither targets a specific do- main with a deterministic pipeline or reports a running operational system with per-KS observability.

  • This paper has chartered the emergence of agentic AI as yet another transformative paradigm, representing a significant evolutionary leap from traditional AI agents and reactive generative AI. We demonstrated that agentic AI, characterized by their goal-oriented autonomous behavior, task decomposition and planning capabilities, and ability to orchestrate the constituent AI agents to interact with external tools, are moving AI to the role of an active problem-solver. Our primary contribution has been to bridge the gap between the high-level theory of agentic AI and its practical, high-stakes application within the field of engineering. To achieve this, we first establish a clear and necessary taxonomy, distinguishing the unique capabilities of agentic AI from its predecessors. Four state-of-the art use cases in the field of electrical engineering are presented, ranging from agentic AI based power system simulation software benchmarking and simulation studies to automated substation illumination design, automated bill-of-quantity generation, and advanced survival analysis for EV framework with the goal to identify the most suitable profit maximizing pricing strategy. However, this transformative potential is accompanied by significant risks. Our investigation into failure modes identified critical vulnerabilities, including the adversarial spread of false information and the cascading degradation of information accuracy through successive LLM rewrites. In response, we proposed tangible mitigation strategies, including the adaptation of a Zero Trust Framework (ZTF) to enforce continuous verification of agent identity and data, and a novel information clustering architecture to protect data integrity. Our technical solutions are complemented by practical recommendations for deploying trustworthy systems, emphasizing the vital role of Humanin-the-Loop (HITL), adherence to emerging AI standards, self-documented immutable audit trails for better accountability of the constituent AI agents that forms the agentic AI framework. Looking ahead, while the potential of agentic AI is clear, its robust and scalable deployment hinges on addressing several key research areas. The following are some of the high-impact research trajectories derived from the gaps we have identified from our current research: • Standardization of engineering tool integration: As highlighted in the power systems case study, the lack of official standardized Model Context Protocols (MCPs) from engineering software vendors such as PSS®E, PowerWorld, CDEGS is a major barrier for standardized deployment. Early progress is likely to be driven by community-developed MCPs, but future research must focus on developing open, stable, and secure MCPs for more robust agenttool interaction to ensure interoperability, reliability, and foster a collaborative development ecosystem.

  • In this paper, we have presented a modification-based ap- proach to splitting assumption-based argumentation frame- works. First, we have introduced a splitting schema for SETAFs, to make splitting available on ABAFs after in- stantiation. Leveraging on the close connection between SETAFs and ABAFs, we have thus proposed a way to split when reasoning in ABA is performed indirectly via the cor- responding argument graph. Moreover, to overcome the re- quirement of an instantiation and its associated costs, we have introduced a splitting schema that works directly on ABA knowledge bases. For both approaches, we have shown that extensions of a given ABAF can be obtained incrementally from its sub-frameworks, by means of sim- ple syntactic modifications. Conversely, we can project an arbitrary extension of the whole framework to its sub- frameworks. Since this is bound to the specific structure of the underlying ABAF, we have considered a more gen- eral variant of splitting called parametrised splitting inspired by Baumann et al. (2012). Moreover, it is easy to see that each of the steps involved can be carried out efficiently and implemented on top of common ABA (or SETAF) solvers. Indeed, the splitting techniques introduced in the paper re- quire only syntactic modifications to the sub-frameworks, which do not lead to an exponential increase in size (and may, in some cases, even reduce it). In particular, through the reduct and modification, we introduce at most one ad- ditional rule and one additional assumption with respect to the original sub-framework.

  • This paper introduced a framework for self-evolving software agents that integrates automated software evolution principles within a BDI architecture augmented by LLMs. By separating runtime reasoning from an explicit evolution module, the proposed approach enables agents to autonomously revise goals, reasoning structures, and executable actions, moving beyond traditional notions of behavioural adaptation. The prototype and preliminary evaluation demonstrate the feasibility of autonomous evolution in dynamic multi-agent environments, while also revealing current limitations in behavioural inheritance, stability, and scalability. These challenges point to the need for reinforcement mechanisms, memory consolidation, and more robust selection strategies. Future work will focus on strengthening inheritance and longterm consistency, extending the evaluation to more complex multiagent scenarios, and exploring collective and cooperative forms of software evolution among agents, as well as leveraging retrievalaugmented generation to enhance LLM reasoning with external knowledge.

  • We view AgentFuel as a first but significant step in advancing evals for timeseries analysis agents. We conclude by acknowledging several limitations and directions for improvement. First, we focus only on the analysis workflow and ignore other issues in data 9 wrangling or data cleaning. Second, we focus on one-shot agents that answer the question as posed; a natural direction is to extend AgentFuel to agents that can ask questions to refine the intent. Third, we showed the value of AgentFuel as a testing framework. As future work, we plan to provide more fine-grained debugging (e.g., possibly connecting with backend tracing) to understand failure patterns and continuous training.
