With the rapid development of the Internet, the demand for high-quality nuclear data services continues to grow. As the main carrier of network traffic, data centers face huge challenges in network resource management. In order to optimize the performance indicators of network flow (such as delay, jitter and packet loss rate, etc.), it is necessary to study the core data evaluation system and modeling. Through the theoretical introduction of nuclear data evaluation system and modeling and ABC-BP hybrid algorithm, this paper analyzes from three aspects: comprehensive data evaluation, nuclear data network modeling, and data evaluation system construction. Based on the relevant theoretical research of ABC-BP hybrid algorithm Based on the analysis of the feasibility of the nuclear data evaluation system and modeling research based on the algorithm theory, the existing nuclear data evaluation system and modeling system in the relevant literature are deeply discussed and studied. Scientific and operable evaluation index system to conduct nuclear data evaluation system and modeling for the ecological development of my country’s government open data, so that it can truly understand its own system status. According to the existing problems of the system, reasonably coordinate and configure the relationship between the elements in the system, and finally realize the balanced, stable and efficient operation of the system.The final experimental results show that when the data fusion coefficients are 49.7, 31.6, 56.3, 73.9 and 60.5, the corresponding data compatibility degrees are 76.9%, 80.2%, 78.4%, 77.1% and 79.3%, respectively. And the compatibility of the nuclear data evaluation system is always maintained at the level of about 78%, indicating that the nuclear data evaluation system based on the ABC-BP hybrid algorithm has good feasibility in terms of data compatibility.
