Description

Technical Field

[0001] The present invention relates to the technical field of experimental simulation modeling in the field of information dissemination, and in particular to a packaging-oriented heterogeneous multi-modal simulation model description method, device, equipment and medium. Background Art

[0002] Simulation models are the basis for using simulation methods to study complex systems. Complex systems have the characteristics of involving a wide range of fields, multiple components, complex relationships between elements, and a long life cycle, which makes the reuse of simulation models developed by multidisciplinary collaborative design more prominent.

[0003] At present, simulation modeling research is in a transition period from a collaborative stage characterized by internal sharing within departments to an engineering stage characterized by field sharing. Using simulation methods to conduct field scientific experiments requires full use of heterogeneous and multi-modal simulation model resources within the field. In order to reuse simulation model resources within the field, there are four simulation model integration methods: the first is the customized development method, in which the integrator conducts secondary development of the integrated simulation model according to the time advancement mode, data interaction format, interface specification, spatial coordinate system and other requirements of the simulation system, and integrates it into the simulation system. This method is suitable for semi-physical simulation models and digital simulation models, but it has high time and labor costs. The second is the middleware method, in which the integrator creates middleware software, such as HLA, TENA, XMSF, etc. This middleware is responsible for coordinating different time advancement modes, providing unified entity management and data interaction functions, and providing unified data formats and interface specifications. This method is not only suitable for semi-physical simulation models and digital simulation models, but can also be applied to the integration between two heterogeneous simulation systems to solve the problem. The problem of reusing simulation models in legacy systems. However, this method not only requires the development of middleware, but also requires adaptive transformation of the simulation models and simulation systems to be integrated, which has high time and labor costs. The third is the encapsulation method, such as FMI. The integrator builds a encapsulation tool, which is used to formally describe the integrated model and perform secondary encapsulation of the interface and interaction data. This method is currently only used in engineering-level models with high resolution. It has low time and labor costs, but it cannot describe the complex domain behaviors of simulation models. The fourth is the assembly method. This method is suitable for isomorphic simulation model resource libraries. By modifying the parameters and structure of existing simulation model resources, new models are generated. For example, the model management tool of Huaru XSIM simulation system provides this simulation model construction method. Although this method has low time cost.

[0004] Known packaging tools perform formal description of the model to be integrated and secondary packaging of interfaces and interaction data. This method is currently only used in engineering-level models with higher resolution, with low time and labor costs, but it cannot describe the complex domain behaviors of simulation models.

[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Combine the following Figures 1 - 3 The invention describes the packaging-oriented heterogeneous multi-modal simulation model description method, device, equipment and medium.

[0018] Figure 1 A schematic diagram of a process flow of a packaging-oriented heterogeneous multi-modal simulation model description method provided by the present invention is shown, see Figure 1 ,The method is applied to a heterogeneous multi-modal simulation model of information ,propagation system, and includes the following steps: Step 11, determine the overall description template corresponding to the simulation model resource information, the overall description template includes multiple first description items, and obtain the first to-be-encapsulated resource information corresponding to the first description item from the resource database based on the first description item in the overall description template; the simulation model resource information is the data obtained by parsing the simulation model, including resource information under different first description items; the resource database stores the correspondence between the first description item and the first label.

[0019] Step 12: Based on the correspondence between the first description item and the sub-description template, determine the sub-description template corresponding to the first description item in the template library, the sub-description template includes multiple second description items, obtain the second to-be-encapsulated resource information corresponding to the second description item from the resource database based on the second description item in the sub-description template, parse the resource information under the first description item, and obtain the resource information under different second description items; the first description item is the parent overview item of the second description item.

[0020] Step 13: Based on the overall description template and the first resource information to be packaged, as well as the sub-description template and the second resource information to be packaged, construct a first packaging description file and a second packaging description file, which together constitute a packaging description file of the simulation model.

[0021] Regarding steps 11 to 13, it should be noted that information propagation simulation is a method used in scientific experiments in the military field to analyze and study complex problems. To solve complex problems using simulation methods, it is necessary to model the structural characteristics and behavioral laws of the smallest identifiable microscopic unit (such as radar), and to analyze the macroscopic characteristics and laws of complex systems by observing the uncertain operating data of the smallest identifiable microscopic unit.

[0022] Currently, simulation modeling research is in a transition period from a collaborative stage characterized by sharing within departments to an engineering stage characterized by sharing in the field. Using simulation methods to conduct scientific experiments in the field requires full use of heterogeneous and multi-modal simulation model resources within the field.

[0023] Model integration usually refers to the collection of multiple models or various components of models to form a complete and coordinated system. In order to meet the reuse requirements of multi-form and heterogeneous simulation model resources in the field, it is necessary to unify the formal description of multi-form and heterogeneous simulation model resources in the field to describe the complex domain behavior of the simulation model and provide technical support for the integration of heterogeneous simulation models.

[0024] In the present invention, for the encapsulation description of heterogeneous simulation models for information dissemination systems, it is first necessary to determine an overall description template for the simulation model resource information of each heterogeneous simulation model. The overall description template can reasonably summarize each heterogeneous simulation model to achieve reasonable integration between the heterogeneous simulation models.

[0025] In the present invention, multi-form refers to the form of simulation model resources when they are used. According to whether physical components are used, simulation model resources are divided into two forms: digital and semi-physical. Digital form simulation models are divided into two forms: system embedded and system independent according to the degree of coupling with the simulation system. System embedded means that the simulation model cannot be separated from the simulation system, and the simulation model resources therein must be used in the form of the system. System independent means that the simulation model can be separated from the simulation system and used in a form. System independent form simulation model resources can be further divided into two forms: component and entity according to modeling technology. Component form is a simulation model resource constructed using component technology, and entity form refers to a simulation model resource not constructed using component technology. According to this classification method, simulation model resources are summarized into four forms: component, entity, system, and semi-physical.

[0026] Heterogeneity refers to the differences in morphology, semantics, and pragmatics between the above four different forms of simulation model resources. Morphology, semantics, and pragmatics are the hierarchical divisions of language description capabilities in cognitive linguistics. Language is a means of interaction between simulation model resources. Integration is to solve the heterogeneity problems between these resources at the three levels of morphology, semantics, and pragmatics. Morphological layer heterogeneity refers to the differences between the simulation model to be integrated and the simulation system in terms of development language, operating environment, time stepping mechanism, program interface, parameter type, etc. Semantic layer heterogeneity refers to the differences in functions and logic of the simulation model in generating behaviors based on control instructions. Pragmatic layer heterogeneity refers to the military problems targeted by the simulation model, the differences in resolution assumptions, simplifications, and constraints on relationships between models made during the modeling process, that is, the heterogeneity of application scenarios (Context). Since simulation modeling usually follows the principle of simplicity and abstracts and assumes the real world, this makes the application scenario an important factor affecting model reuse.

[0027] Multiple description items are configured on the general description template (in order to better distinguish them from description items of different description templates, they are used as the first description items here), and then the corresponding first resource information to be packaged is obtained based on the first description item in the general description template. The simulation model resource information is the data obtained by parsing the simulation model, including resource information under different first description items; the resource database stores the correspondence between the first description item and the first label, and the resource information under each description item is determined based on the correspondence as the first resource information to be packaged.

[0028] Each description item needs to be configured with corresponding description information. These description information, as the resource information to be encapsulated, need to be configured according to the template to obtain the encapsulation description file. For example, the encapsulation resource information of the simulation model that the encapsulation user needs to describe includes basic information, spatiotemporal granularity information, quality information, operation dependency information, structure information, interface parameter information, object model information, and dimension information. Here, the first description item of the overall description template can be basic information, spatiotemporal granularity information, quality information, operation dependency information, structure information, interface parameter information, object model information, and dimension information.

[0029] In the process of building a simulation model, formal description refers to the process of using precise mathematical language or logical symbols to express the problems, requirements or solutions that appear in the simulation process. This description method aims to eliminate ambiguity and ensure the accuracy and consistency of the description, so as to facilitate the analysis and verification of the simulation model for the system business.

[0030] In the present invention, multiple description items will be configured on the above-mentioned overall description template, and further configuration is also required to construct the corresponding package description file. Therefore, based on the correspondence between the first description item and the sub-description template, the description template corresponding to the first description item is determined in the template library (here, in order to distinguish it from the overall description template, it is used as a sub-description template), and each sub-description template includes multiple second description items. The resource information under the first description item is parsed to obtain the resource information under different second description items; the first description item is the parent overview item of the second description item. Based on the second description item in the sub-description template, the corresponding second resource information to be packaged is obtained. If the first description item is basic information, the description items in the corresponding description template include model model, name, function, development unit, development language, and production time. Here, the second description item may include model model, name, function, development unit, development language, and production time.

[0031] In the present invention, based on the overall description template and the first resource information to be packaged, as well as the sub-description template and the second resource information to be packaged, a first package description file and a second package description file are constructed. The first package description file and the second package description file together constitute the package description file of the simulation model.

[0032] In the present invention, during the model integration process, the packaging description files of heterogeneous simulation models are compared and analyzed to determine the integration location points between the heterogeneous simulation models, or the integration improvement location points between the heterogeneous simulation models are analyzed, and the corresponding packaging description files are updated at the integration improvement location points.

[0033] The encapsulation-oriented heterogeneous multi-modal simulation model description method provided by the present invention constructs a first encapsulation description file and a second encapsulation description file based on an overall description template and first resource information to be encapsulated, as well as a sub-description template and second resource information to be encapsulated, thereby realizing a hierarchical and unified description of heterogeneous simulation model resource information, so as to describe the complex domain behavior of the simulation model and provide technical support for the integration of heterogeneous simulation models.

[0034] In a further method of the above method, the process of determining the overall description template corresponding to the simulation model resource information is mainly explained as follows: Acquire simulation models under different application services, where the simulation models under different application services are heterogeneous models; Analyze the simulation models under different application businesses to obtain the difference information between the simulation models in terms of morphology, semantics and pragmatics; Based on the difference information, divide the first description items into a plurality of first description items; Based on the multiple first description items, an overall description template is constructed.

[0035] In this regard, it should be noted that in the present invention, in order to achieve a unified description of heterogeneous simulation model resource information, it is necessary to analyze the description items that can be uniformly described from the simulation models under different application services. To this end, the simulation models under different application services are parsed to obtain the difference information between the simulation models at the morphological, semantic, and pragmatic levels. There is difference information, and unified content that can be integrated can be screened from the difference information. For example, model A and model B can be associated with the application business in the spatial coordinate system, so the model part in the spatial coordinate system is used as the unified content that can be integrated. Therefore, based on the difference information, multiple description items are divided, and further based on multiple first description items, an overall description template is constructed.

[0036] In the present invention, the formal description of the overall description template is: MEInfo= { BInfo, TSR, Qua, DepCtx, MStruct, InPar, ObjMod, Dim} in, MEInfo It represents the resource information of the simulation model, BInfo represents the basic information of the model, TSR represents the spatiotemporal granularity information of the model, time refers to the time advancement mechanism of the model, space refers to the spatial coordinate system adopted by the state variables and parameters of the model, and granularity refers to the modeling granularity of the model; Qua represents the model quality information; DepCtx represents the operation dependency information of the model, for example, the radar model depends on the detected model; MStruct represents the model entity structure information, InPar represents the interface parameter information, and ObjMod represents the object model information, which is used to standardize the content and format of the interactive information during the instantiation and operation of the model. It should be noted that the operation interactive information is different for models of different granularity, and Dim represents the dimensional information.

[0037] In the present invention, determining the sub-description template corresponding to the first description item includes: filtering out the target content in each heterogeneous simulation model based on the first description item; determining the sub-content from the target content, and then determining the overview words based on the word content, making the overview words as the description item, and then determining the sub-description template based on the description item. Furthermore, the input substitute words can also replace part of the overview words, and then determine the sub-description template based on the description item and the substitute words. If the first description item is spatiotemporal granularity information, then the target content in each heterogeneous simulation model can be filtered out based on the spatiotemporal granularity information, the target content can be divided into sub-contents, and then the overview words can be summarized as time advancement mechanism, space coordinate system, and modeling granularity based on the word content.

[0038] In a further method of the above method, the description items of the above overall description template include basic information, spatiotemporal granularity information, quality information, operation dependency information, structural information, interface parameter information, object model information, and dimensional information.

[0039] Basic InformationBInfo Including model type, name, function, development unit, development language, production time, formal description is: Binfo= { MType, MName, MFun, MProUnit, MLan, MEnvTime, MVersion} MType Represents the model type, which is the unique identifier of the model in the model library.

MFun Represents the functionality of the model, MProUnit Indicates the model production unit, MLan Represents the model development language, MEnvTime Indicates the model packaging time, MVersion Indicates the version of the model.

[0040] The coding rule of the model number is the combination of the model name, production unit, and language abbreviation. For example, the model number of the X model developed by unit A using the C++ language is "XA-C++".

[0041] The model version coding rule is "XX.XX.XX.XX", where X represents the version number. The first two digits are the first-level version number, which indicates the version of the integration framework used for encapsulation. The third and fourth digits are the second-level version number, which is changed when the function changes. The fifth and sixth digits are the third-level version number, which is changed when the model confidence is improved. The seventh and eighth digits are the third-level version number, which is changed when the bug is fixed.

The formal description is: Mstruct ={ MRMorph, MIntegrity, MLCset} in, MRMorph Represents the model form, including components, entities, systems, semi-physical / physical; MIntegrity Indicates the integrity of the model, including complete and incomplete values, which are used to describe whether the model can directly participate in the simulation in the simulation system. For example, some semi-physical models of mobile types lack components such as communication and cannot directly participate in the simulation. They need to be integrated with digital component models to form a complete model before they can participate in the simulation. MLCset Indicates the set of functional components that are missing from the model. This item needs to be filled in when the model completeness value is incomplete.

[0046] Model interface parameter information InPar It is used to describe the relationship between the encapsulation model interface and the standard model interface parameters. It includes five parts: interface type, interface name, interface mapping relationship, interface return value type, and interface parameter set.

The corresponding standard parameters can be obtained by calculating multiple parameters of the package model. Currently, only four types of calculations, addition, subtraction, multiplication and division, have been verified; PDef Indicates missing relationship, that is, the package model has no parameters corresponding to the standard parameters, and the standard parameters cannot be calculated through the remaining parameters; PRd Indicates a redundant relationship, that is, the encapsulated model has parameters other than the standard parameters; PTran Indicates a conversion relationship, that is, the package model parameter needs to be converted before it can be mapped to the standard parameter. For example, if the package model parameter is of string type and the standard model parameter is of int type, the package needs to convert the string type to int type, then a conversion relationship exists for the parameter.
