Exploring Graph Neural Networks for Complex Business Process Mining: Data-Driven Insights in Networked Systems

Graph Neural Networks, Business Process MiningAbstract
This paper investigates the application of Graph Neural Networks (GNNs) for mining complex business processes within networked systems. Traditional process mining techniques predominantly focus on extracting process models from event logs by identifying sequential patterns, which may overlook the intricate interdependencies and dynamic relationships that characterize business operations. In contrast, GNNs, which have gained prominence in the domain of machine learning, offer a novel approach to understanding and analyzing complex networks by representing entities as nodes and relationships as edges within a graph structure. This study explores how GNNs can be effectively leveraged to model, predict, and optimize business processes that operate within interconnected environments, where the performance and outcomes of processes are influenced by the interrelations between various entities involved in the system.
Business process mining has evolved beyond the analysis of individual tasks, seeking to incorporate the contextual and relational data that define how these tasks interact across multiple entities. In networked systems, the relationships between process components, such as departments, personnel, and external systems, often play a decisive role in the efficiency and effectiveness of the process outcomes. Standard process mining approaches struggle to account for these complexities, focusing instead on linear or tabular representations of events. However, GNNs naturally align with the structure of such systems, enabling the modeling of complex dependencies between different process components, thus offering a richer and more accurate understanding of process behavior.
Graph Neural Networks, as a type of deep learning model, are particularly suited for applications involving structured relational data. They allow the learning of node and edge representations that encapsulate not only individual process entities but also the context in which these entities interact within a broader system. This ability to capture both local and global relationships within a network is critical for mining business processes that span multiple organizational boundaries or involve complex workflows where traditional sequential or time-series models may fail. Moreover, GNNs can be extended to incorporate dynamic changes in the network, such as organizational restructuring or shifts in process priorities, which can significantly impact the overall system performance.
The potential benefits of applying GNNs in business process mining are manifold. By representing business processes as graphs, it becomes possible to predict the flow of tasks, identify bottlenecks, and uncover hidden patterns that may otherwise remain undetected using conventional methods. Furthermore, GNNs can facilitate the optimization of business processes by simulating potential changes to the system and evaluating their impact on key performance indicators (KPIs). This predictive capability is especially valuable in networked systems where the interactions between process components are nonlinear and interdependent, requiring advanced models to accurately forecast outcomes and suggest improvements.
This paper also discusses the key challenges associated with applying GNNs to business process mining. One primary challenge is the availability and quality of data. Business process data often comes in diverse formats, including event logs, workflow models, and unstructured communications, which may not readily fit into the graph structure required for GNNs. Preprocessing and transforming such data into a suitable format is a crucial step for successful GNN application. Additionally, the scalability of GNNs in handling large-scale networked systems with thousands of nodes and edges remains an open challenge. While GNNs have shown promise in smaller-scale applications, further research is needed to address issues related to computational efficiency and model interpretability when dealing with complex, real-world business networks.
Despite these challenges, several case studies and empirical examples demonstrate the successful use of GNNs in various business process mining scenarios. These applications highlight the ability of GNNs to uncover relationships between disparate entities, leading to insights that can drive process improvements, reduce inefficiencies, and enhance decision-making. For instance, in supply chain management, GNNs have been used to model the interdependencies between suppliers, manufacturers, and distributors, enabling the identification of vulnerabilities and optimization opportunities. Similarly, in customer service operations, GNNs have been applied to analyze interactions between customer support agents, systems, and customer profiles, improving response times and satisfaction rates.
