The invention discloses a computer device for independent behavior network investment planning, an independent behavior network investment planning method, a medium and equipment. The device comprisesan index establishing module used for acquiring operation data of a target independent behavior network and establishing an operation index corresponding to the full life cycle cost and the power supply reliability of the target independent behavior network; a fault set generation module used for generating a target fault data set according to the historical fault data of the target independent behavior network; a model establishing module used for establishing a target investment planning model of the target independent behavior network based on time sequence Monte Carlo simulation; a modelsolving module used for solving the target investment planning model to obtain a target Pareto graph; and a scheme determination module used for determining a target investment planning scheme of thetarget independent behavior network by utilizing the target Pareto graph. Therefore, the construction cost of the target independent behavior network is relatively lowest, and the whole life cycle cost and the power supply reliability of the target independent behavior network can also be considered.
