Towards Multi-Turn Dialog Systems for Industrial Asset Operations and Maintenance
For industrial practitioners, this work addresses the bottleneck of tool invocation in multi-turn dialog systems, offering a practical solution with measurable efficiency gains.
The paper presents a multi-turn dialog system for industrial asset operations and maintenance using a supervisor-specialist multi-agent architecture. It achieves a 54.5% increase in planning effectiveness and a 37.8% improvement in task completion over the baseline, while reducing tool-time share from 47.3% to 26.3%.
Industrial asset operations and maintenance question answering is inherently multi-turn, iterative, and highly dependent on external tool invocation. However, the conventional plan-execute single-agent architecture exhibits clear limitations in maintaining cross-turn context, and reusing intermediate results. In this paper, we present a multi-turn dialog system designed for industrial scenarios based on a supervisor-specialist multi-agent architecture. To alleviate tool invocation bottlenecks, the system incorporates structured artifact reuse, dynamic replanning, and parallel tool execution. Evaluation results show that our system achieves better response quality compared with the baseline, with planning effectiveness increasing by 54.5% and task completion improving by 37.8%. System profiling further shows that cross-turn artifact reuse effectively reduces redundant tool invocation, decreasing the tool-time share from 47.3% to 26.3% and making turns 2-5 approximately 4.2x faster than the first turn.
