Abstract

The invention discloses an intelligent decision making system reduction method based on ant colony, Comprising the following steps: (1) solving the attribute core of a decision making system, and initializing mutual information and iteration time; (2) generating k ants, initializing the k ants by the attribute core, and randomly selecting certain attribute for the k ants; (3) calculating heuristic information composed of attribute importance degree and pheromone; (4) selecting next attribute for each ant according to the heuristic information; (5) if the mutual information of the current ant is equal to the initial mutual information, ending the ant, and otherwise turning to (3); (6) obtaining a local solution; and (7) if the mutual information is less than the maximum iteration time or evolutionary trend, obtaining a global solution, outputting a minimum reduction, otherwise updating the pheromone and turning to (2). According to the technical scheme disclosed by the invention, the minimum reduction of the attribute in the decision making system can be quickly and effectively obtained, and information accuracy is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a reduction method of a decision-making system based on ant colony intelligence. Background technique [0002] Decision support system is a computer application system that assists decision makers to make semi-structured or unstructured decisions through human-computer interaction through data, models and knowledge. It is an advanced information management system produced by the development of management information system to a higher level. It provides an environment for decision makers to analyze problems, build models, and simulate decision-making processes and programs, and calls various information resources and analysis tools to help decision makers improve their decision-making level and quality. Decision support systems have been widely used in many industries such as industry, agriculture, and commerce. The decision support system is referred...
