Embodiment Construction

[0025] The purpose of the present invention is to provide a method for constructing an ontology-based imaging satellite scheduling problem model that can describe the imaging satellite scheduling problem in a generalized manner.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the present invention. .

[0027] In one embodiment, as figure 1 As shown, the present invention provides a method for constructing an ontology-based imaging satellite scheduling problem model, and the specific steps of the method are as follows:

[0028] (1) Take tasks, resources, scheduling time range, constraints, goals, preferences, and scheduling requirements as related items of imaging satellite...

Abstract

The invention discloses an imaging satellite scheduling problem model building method based on a body. The method comprises the following specific steps of (1) treating tasks, resources, a scheduling time range, restraints, goals, preferences and scheduling demands as related items of an imaging satellite scheduling problem, (2) combining the related items of the tasks, the resources, the scheduling time range, the restraints, the goals, the preferences and the scheduling demands with specific application knowledge to carry out instantiation on the mutual relation, and generating a specific application model, and (3) building the specific application model by the utilization of a body tool, and describing the body of the specific application model through a standard format. According to the imaging satellite scheduling problem model building method based on the body, a problem domain is confirmed by building the goals, the restraints and problem parameters, and accordingly the imaging satellite scheduling problem can be described generally.

Description

technical field [0001] The invention relates to the technical field of aerospace imaging satellite scheduling, in particular to an ontology-based imaging satellite scheduling problem model building method. Background technique [0002] There is currently no unified definition of ontology. Chandrasekaran and others believe that ontology is the research content in the field of artificial intelligence, which studies the object classification, object attributes and the relationship between objects of specific domain knowledge, and provides specifications for the description of domain knowledge. Semantic Web researchers believe that ontology is a formal specification that defines the relationship between words. Although the definition is not uniform, it is generally recognized that ontology has the meaning of formalization, knowledge sharing and interoperability. Ontology has a set of classification system and a series of inference rules, which can map between different modelin...
