Description

Technical Field

[0001] The present invention relates to the technical field of audit business process control, and in particular to an automated audit business process control method based on rule optimization. Background Art

[0002] With the rapid development of information technology and big data analytics, auditing is gradually shifting towards digitalization and automation. Traditional, manually conducted audit processes are being replaced by intelligent systems. Existing automated audit systems typically manage and control audit processes through rule engines, which process and analyze audit data using predefined rule sets. However, most existing rule engines rely on static rule sets, lacking dynamic adaptability and intelligent optimization capabilities, making them difficult to meet the ever-changing business needs of complex audit scenarios.

[0003] The rule engine in the existing technology is usually composed of a single rule layer, which is directly applied to all audit scenarios, ignoring the differences between different audit businesses. The scope of application of static rules is fixed, and the logic and applicable conditions of the rules cannot be adjusted according to real-time business scenarios. This leads to problems such as low rule execution efficiency and unreasonable priority allocation of audit nodes. In addition, the existing technology has weak conflict handling capabilities between rules. Logical conflicts or redundancy between rules may cause deviations in the execution results of the audit process. For example, when multiple rules are applied to the same node, the allocation of rule priorities usually relies only on predefined weights or simple relevance scores, ignoring the dynamic impact of rule execution history and real-time feedback data on rule effectiveness.

[0004] When it comes to audit process optimization, existing technologies mostly use static path planning, generating task paths based on established rules and node priorities. However, static planning cannot cope with the dynamic changes in node priorities during the audit process. In particular, when high-priority tasks emerge, existing systems struggle to reallocate resources to ensure the prioritized completion of critical node tasks. Furthermore, task path planning typically only considers node priority and execution order, ignoring multidimensional factors such as task complexity, resource consumption, and execution time. This not only leads to overall inefficiency in the audit process but can also cause significant imbalances in resource allocation.

[0005] When it comes to intelligent rule optimization and process control, existing technologies often rely on simple optimization algorithms, such as genetic algorithms and particle swarm optimization. These algorithms often suffer from slow convergence and proneness to local optimality when faced with complex audit scenarios involving multiple rules, multiple nodes, and multiple objectives, making it difficult to quickly generate high-quality rule optimization solutions. Furthermore, most existing optimization algorithms ignore real-time feedback data during rule execution, resulting in a lack of dynamic adjustment capabilities during the optimization process. For example, when the scope of application or triggering conditions of a rule change, existing systems are unable to adjust the optimization direction in real time, resulting in insufficient adaptability of the rule set and insufficient precision in process control.

[0006] Another significant issue is that existing technologies lack a mechanism for continuous optimization and iteration of rules and processes. Audit process execution is typically static and consistent, while rule set updates often rely on manual intervention or periodic maintenance, making it impossible to achieve dynamic adaptation of rules and processes. Because the effectiveness of rule execution and the real-time status of process nodes are not fully utilized, existing systems struggle to form efficient closed-loop optimization mechanisms. Long-term use can lead to rule failure or decreased process efficiency. Furthermore, existing technologies lack transparency in rule execution plans, preventing users from effectively tracking the logic and process of rule optimization, further limiting the system's application in highly complex scenarios.

[0007] Therefore, how to provide an automated audit business process control method based on rule optimization is an urgent problem that those skilled in the art need to solve. Summary of the Invention

[0072] First, the present invention addresses the existing issues of rule rigidity and insufficient applicability by constructing a multi-layered rule engine architecture, comprising a basic rule layer, a dynamic rule layer, and a personalized rule layer. The basic rule layer meets general audit requirements, the dynamic rule layer can generate and adjust rules based on real-time business scenarios, and the personalized rule layer builds a customized rule library based on a company's historical data and specific needs. This layered architecture not only improves the flexibility and adaptability of the rules, but also ensures the logical consistency and accuracy of the rule set through rule integration and conflict deduplication.

[0073] Secondly, the present invention introduces an improved swarm optimization algorithm, which significantly improves the efficiency and quality of rule optimization. By dynamically adjusting the search space, the algorithm can flexibly optimize rule parameters based on real-time feedback from the rules, avoiding the problem of traditional optimization algorithms falling into local optimality due to fixed search ranges. The collaborative bee mechanism ensures the global consistency of the rule set and the rationality of the execution logic by optimizing the conflicts between multiple rules. At the same time, the multi-objective weighting mechanism comprehensively considers the accuracy, execution efficiency and coverage of the rules, achieves a dynamic balance of rule optimization goals, and enables the rule set to quickly adapt to complex and changing audit scenarios.

[0074] In addition, the present invention constructs an efficient process control mechanism through the dynamic linkage of rule execution plans and audit processes. Under the guidance of the rule execution plan, the node priority of the audit process can be dynamically adjusted according to the importance of the rules and real-time business needs. The task path is optimized by combining factors such as node complexity, execution efficiency, and resource allocation to generate the optimal path with the lowest time cost. At the same time, by real-time monitoring of node status and rule execution, inefficient nodes and rule parameters are adjusted in a timely manner, and resources are reallocated to prioritize key tasks, effectively improving the execution efficiency and flexibility of the audit process.

[0075] Finally, this invention establishes a continuous iterative optimization mechanism for rules and processes. By standardizing and analyzing real-time feedback data from rule execution, it continuously optimizes rule parameters and scope of application, and simultaneously updates them to the basic rule layer and the personalized rule layer. This closed-loop optimization mechanism ensures that the rule set can dynamically adapt to changes in the business environment and needs, avoiding the problems of rule failure and reduced audit efficiency. At the same time, the continuous iterative optimization of rule execution plans and audit process paths ensures the long-term stability and efficiency of the system, providing comprehensive and reliable technical support for complex audit scenarios.

[0142] Example 1:

[0143] In order to verify the feasibility of the present invention in practice, the present invention was applied to the annual financial audit scenario of a large manufacturing enterprise. The enterprise has a complex financial structure and a multi-level business system, including multiple modules such as supply chain management, capital flow, and inventory accounting. In the traditional audit process, problems such as fixed rules, unreasonable node priority allocation, and insufficient process path optimization lead to long audit cycles, low error detection rates, and uneven resource allocation. Based on these problems, the automated audit business process control method based on rule optimization proposed in the present invention was put into practical application.

[0144] In this example, multi-source audit data from the enterprise's financial system, business system, and third-party platforms was first collected. This data includes account records, inventory transactions, and capital flow information for the past three years, totaling approximately 12 million entries. Using the method of the present invention, the data was cleaned, anomaly detected, and formatted in a standardized manner, forming a unified audit data pool. On this basis, a multi-layered rules engine was constructed, comprising a basic rules layer, a dynamic rules layer, and a personalized rules layer. The basic rules layer covers the financial regulations and tax standards applicable to the enterprise; the dynamic rules layer generates rules in real time to adapt to abnormal data patterns; and the personalized rules layer generates targeted rule sets for the enterprise's historical issues.

[0145] Subsequently, the rule set was dynamically optimized using an improved bee colony optimization algorithm. The worker bee phase performed a local search of rule parameters, generating an optimized rule set based on fitness. The observer bee phase selected the optimal rule direction based on rule execution performance and resolved logical conflicts between rules. The collaborative bee phase optimized the compatibility of multiple rules. The scout bee phase maintained population diversity to prevent the algorithm from falling into local optimality. The optimized rule set generated 120 high-priority rules, 20 of which were newly added to the dynamic rule layer.

[0146] The optimized rule set was input into a multi-layered rule engine, generating a dynamic rule execution plan. Based on the rule execution plan, audit process node priorities were adjusted in real time. For example, the company's high-risk cash flow verification task, which traditionally took an average of 16 hours to complete, only took 10 hours after optimization. The audit time for inventory reconciliation tasks was also reduced from 8 hours to 5 hours. Furthermore, by optimizing task paths, the system can dynamically adjust resource allocation, prioritizing high-priority node tasks when resources are limited, significantly improving overall efficiency.

[0147] Throughout the audit process, this invention continuously optimizes and iterates rules and processes by monitoring rule execution status and task completion rates at process nodes in real time, continuously adjusting rule parameters and priorities, and generating new rule execution plans. Ultimately, the overall audit cycle was shortened from the traditional 10 days to 6 days, the error detection rate for high-risk transactions increased from 65% to 92%, and the rule application rate increased from 78% to 96%.

[0148] Table 1 Comparison of audit process efficiency and effect between traditional method and the method of the present invention

[0149]

[0150] According to the data in Table 1 above, the application of the present invention in the annual financial audit scenario of a certain manufacturing enterprise has significantly improved the efficiency and accuracy of the audit process, while greatly reducing the rule conflict rate and resource waste, reflecting extremely high application value. First, the present invention shortens the audit cycle from 10 days in traditional methods to 6 days through rule optimization and process control, reducing the time cost by 40%. This improvement is of great significance in the annual financial audit of enterprises, especially in time-sensitive audit tasks, as the audit work of the entire process can be completed more quickly. Secondly, the error detection rate of high-risk transactions has increased from 65% to 92%, significantly improving the accuracy and effectiveness of the audit.
