Problems solved by technology

[0004] However, in the current literature on frequency planning issues, the modeling usually only has one-dimensional variables in the frequency domain, and the obtained frequency planning scheme only includes the assignment scheme of the frequency points of each frequency equipment Coordinated scheduling in multiple dimensions such as time domain, air domain, frequency domain, and energy domain

At the same time, it is difficult for the planning model to accurately describe the considerations and requirements of decision makers for the expected implementation of the frequency planning scheme, which may lead to deviations in the judgment of the pros and cons of the solution, resulting in the loss of the ideal frequency planning scheme, and the problem of poor planning effect
