Abstract: Digital technologies continue to empower various industries and have achieved remarkable results.The development and application of digital resources are key to digital empowerment.However,diverse forms of digital resources required to build simulation systems for specific objectives vary significantly,leading to increased complexity in system development and reduced operational efficiency.This paper begins by analyzing the fundamental concepts of digital resources and summarizes their associated application requirements.Subsequently,it proposes a digital resource integration method based on agent model,which demonstrates significant advantages in mitigating the heterogeneity among different digital models within a system.The method is elaborated from two perspectives:1) An agent model-based integration framework which supports the integration of both agent model-based digital resources and those not employing agent models.2) The design of agent models for digital resources which ensures data transmission requirements between agent models (both externally and internally) and facilitates data conversion across different external interfaces.Finally,the effectiveness and flexibility of agent model-based digital resources integration are validated through a real-time satellite trajectory visualization case study.
