In the context of rapid global technological development and intensifying international market competition, the innovation capability of complex products has become a key indicator of a country's industrial strength and technological leadership. Especially against the backdrop of the booming low-altitude economy, drones, as typical complex products, present diverse and dynamic user needs that pose significant challenges to traditional linear modeling methods. In response to the limitations of existing methods in multi-source heterogeneous information fusion, demand correlation identification, and priority analysis, this paper proposes a systematic demand modeling and analysis method based on multi-layer heterogeneous networks.
Specifically, this paper first constructs a multi-layer heterogeneous network structure that encompasses multiple types of nodes such as users, requirements, components, and experts, along with their relationships, systematically presenting the multidimensional interactions between complex product requirements. Secondly, it proposes a knowledge-information-data (KID) integrated demand modeling framework, which combines large language models, semantic recognition, convolutional neural networks, and fuzzy set theory to efficiently extract and model massive unstructured requirement data. Furthermore, it designs a comprehensive demand importance evaluation mechanism under multi-source information conditions, integrating expert trust networks and biased random walk algorithms to effectively identify key requirements and optimize priority ranking. Finally, empirical research is conducted using unmanned aerial systems as the application object, verifying the effectiveness and feasibility of the proposed method in actual requirement modeling and analysis.
This study not only provides an intelligent and systematic analysis path for the demand development of complex products in the data-driven environment, but also provides theoretical support and technical tools for related enterprises to improve the efficiency of product design decision-making and market response ability, which has significant theoretical value and practical significance.
