Target decomposition system and method based on hierarchical risk

The invention discloses a hierarchical risk-based target decomposition system and method, and the system comprises an obtaining module which is used for obtaining a risk corresponding to a target; the layering module is used for carrying out layering processing on the risk to obtain a multi-layer target risk map and defining an index of the risk; and the decomposition module is used for decomposing the obtained multi-level target risk indexes to posts of different levels to form sub-targets of different posts. According to the invention, an effective risk management and control mechanism for all post targets is established through risk changes, and target decision rules related to different responsibilities of an execution layer, an implementation layer and a management layer can be set and are respectively used for the responsibilities of subject responsibilities, supervision responsibilities and leader responsibilities in a target layer and a task layer. In this way, closed-loop management of all levels of
