The invention belongs to the field of task environment efficiency evaluation, and particularly relates to a space-time environment influence efficiency evaluation method and system based on minimum cost planning, and the method comprises the steps: constructing a space-time environment comprehensive influence model which is used for describing the continuous change of task space-time environment influence factors along with time according to the space-time environment influence factors, the space-time environment influence factors at least comprise an environment variable, a situation variable and a capability variable which influence task execution, and a rule that the three variables continuously change along with time; and solving the model through the minimum cost, searching in a feasible time-space domain to obtain a minimum cost scheme of each type of cost, and evaluating the task efficiency by using the performance of the minimum cost scheme. According to the method, the mutual influence relation and the dynamic process of the five objects including the task, the environment, the situation, the capacity and the time are comprehensively analyzed, comprehensive evaluation of the influence efficiency of the space-time environment on task execution is achieved, and technical support is provided for formulating a task execution scheme with the overall space-time optimization and the minimum cost.
Description
technical field [0001] The invention belongs to the field of task environment performance evaluation, in particular to a method and system for evaluating the performance of space-time environment impact based on minimum cost planning. Background technique [0002] In a specific domain, a task refers to a single-stage action in a physical space. Task is a broad concept, which is an orderly collection of a series of interrelated actions performed by an action unit to complete its responsibilities or achieve a specific purpose under certain environmental and time-space constraints, including in physical space and non-physical space. Actions in multiple stages of physical space, and the association and collaboration between stages. There are mutual influences or dependencies between the actions at each stage, which is a complex combination. In addition to the basic environmental impact, what is more important is the ingenious strategy. A single-stage action refers to a staged ...
