Embodiment Construction

[0058] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0059] see figure 1 , is a system modeling and optimization method based on a high-dimensional approximate model of the present invention, comprising the following steps:

[0060] Step S100: collect system data, or construct a system mechanism simulation scheme. Data is the key to building a high-dimensional approximate model. There are two main sources of data: collecting actual data on site; or building a system mechanism simulation program, generally using general-purpose simulation software, to obtain a simulation with a high degree of similarity to the actual behavior of the system data.

[0061] Step S200: Analyze the behavior characteristics of the modeling object, select input and output variables, and determine the value ra...

Abstract

The invention discloses a system modeling optimization method and a storage medium. The method comprises the following steps of: analyzing behavior features of an object system, selecting input variables and output variables, determining a value range of each input variable, and obtaining an input data set and an output data set; determining a high-dimensional approximation model of each output variable; solving undetermined parameters in the high-dimensional approximation models to ensure that the errors between a model prediction value and the input and output data sets are minimum in a set high-dimensional approximation model error range; and optimizing the behavior features of the object system on the basis of the solved high-dimensional approximation model. According to the method, a high-dimensional approximation model method with high efficiency and high precision is developed to solve the modeling and optimization problems of complex systems.

Description

technical field [0001] The invention relates to the field of system modeling, in particular to a complex system modeling and optimization method. Background technique [0002] Complex systems exist in every corner of the world, such as industrial systems (process operations, factory production, supply chain management, etc.), ecosystems (human social activities, environmental changes, etc.). It contains a large number of units and subsystems, and there is a strong coupling between units and subsystems. It is an extremely difficult task to accurately describe all the mechanisms in a complex system with mathematical models. By analyzing the data of the research object, it is the purpose of the data-driven approximate model to obtain the description expressions of the process variables (input, output and intermediate variables) of the system. Therefore, for this type of research object, modeling with an approximate model is the best solution. The approximate model has the ad...
