In this embodiment, by determining the process resource information of the first process to be managed, determining the target dependent process according to the process resource information, and then taking the target dependent process as the second process to be managed, since the process resource information can effectively characterize the dependency relationship between the processes, accurate identification of the target dependent process can be realized in a plurality of processes of the operating system based on the process resource information of the first process to be managed, thereby effectively improving the accuracy of the obtained second process to be managed. Determining a dependent process group according to the process resource information, wherein the dependent process group comprises: the method comprises the steps of determining a dependence process group based on process resource information, and taking the candidate dependence process in the dependence process group as a target dependence process. Because the process with the direct dependency relationship or the indirect dependency relationship with the first process to be managed may cause the abnormal running state of the process after the first process to be managed is cleared, when the process with the direct dependency relationship or the indirect dependency relationship with the first process to be managed is used as a candidate dependent process, the accuracy of the obtained target dependent process can be effectively improved, and thus the resource control effect is ensured. The user layer configuration information of the running application program is obtained, the associated process is determined according to the application process information, the associated process is determined to be the third process to be managed according to the user layer configuration information, and because the user configuration information can be flexibly configured by a user according to an application scene in advance, when the third process to be managed is determined by combining the user layer configuration information and the application process information, the influence on the user use experience in the resource control process can be reduced to a greater extent, and the practicability of the resource control method of the operating system can be effectively improved. By selecting the association process from the plurality of association processes as the third process to be managed according to the user layer configuration information, secondary screening can be performed from the plurality of association processes based on the user layer configuration information, processes with larger influence on the user layer are avoided from being cleared, and robustness in the resource control process can be effectively improved.
