Description
Technical field
The present invention relates to modeling and simulation technology field, be specifically related to a kind of reusable realistic model and exploitation thereof and using method.
Background technology
Complication system emulation often comprises a large amount of entities; comprise again multiple model in entity, and these models often relate to numerous specialty, needs and numerous R&D institution cooperate; in order to protect the intellectual property, model often submits to user with packaged actuating code form.Owing to lacking unified reusable Simulation Model Development specification and the guidance of development approach, between the interface disunity causing the model of commensurate exploitation outwards to provide, model the degree of coupling comparatively large, bind closely with emulation platform, such that the integrated difficulty of realistic model is large, model reusability is difficult.Meanwhile, along with deepening continuously of Simulation Application, complication system Solid simulation model presents the trend of substantial amounts, of a great variety, mutual complexity; And, on the one hand, along with deepening continuously and the appearance of complication system ingredient new feature of people's understanding, department pattern in complication system Simulation Application often needs constantly perfect, even develop new model, this just requires the degree of coupling as far as possible reduced between model, reduces model modification to the impact of other model, reuses with zero amendment realizing other model a large amount of; On the other hand, people often wish by the Simulation model reuse developed in other analogue system in need (as by certain early warning radar models applying in different operation simulating experimental systems), and this not only requires that between model, the degree of coupling is little, but also require that realistic model is not bound with emulation platform.
Model reusability is the important channel of improving Simulation Application system development efficiency, after the Building of Simulation Model of Reuse-oriented, without the need to or only need do a small amount of amendment and just can directly reuse in new Simulation Application, thus avoid the overlapping development of low level, improve the development efficiency of Simulation Application, in addition, the model reusability realized based on unified interface specification also will bring following benefit
[1]: (1) is encapsulated into the knowledge relevant to field in Reusable Model, make in the process building Simulation Application, application developer only need by these model integrated in corresponding simulation frame, without the need to paying close attention to the domain-specific knowledge that model relates to, the exploitation threshold of Simulation Application so just can be reduced; (2) by setting up corresponding model bank, unified management being carried out to Reusable Model, breaking the restriction of professional domain, realize sharing and reusing of each class model resource, reduce the development and maintenance cost of Simulation Application.
Research at present for model reusability mainly comprises following direction:
1, based on the Reusable Model development approach of modeling language
Modeling language is special Simulation-Oriented Modeling and Design, the copying modular design of specific area is normally modeling primitive by its principle, the scheduling of emulation and control module are designed to emulator, the bottom layer realization automatic mapping function of modeling language to universal programming language.Modeling language achieves being separated of model and emulator, greatly reduces modeling difficulty, improves the reusability of realistic model.But, modeling language does not have field independence usually, as the Modelica language etc. of the ACSL language towards continuous system simulation, the GPSS language towards discrete event system simulation, multi-domain Oriented physical simulation, when applying towards complication system multi-domain simulation, modeling language also exists inborn deficiency
[2].
2, based on the Reusable Model development approach of modeling specification
Simulation modeling specification is that realistic model defines unified inner structure, behavior and external interface, makes realistic model after having developed, without the need to or only need do a small amount of amendment and just can directly reuse in new Simulation Application.Usual simulation modeling specification does not limit concrete programming language and operation support platform, may be used for instructing building reusable realistic model.
Ou Hang office (ESA) proposed the realistic model Description standard SMP2(SimulationModelPortabilityStandards2 of Reuse-oriented in 2004)
[3].The object of SMP2 standard is to provide a model development framework, reuses so that the platform realizing realistic model is independent, cross-platform, adopts the thought based on assembly to support the modular design of realistic model and service of simulation.But SMP2 specification abstraction hierarchy is higher, be not suitable for the exploitation of guiding function level, low level realistic model.
Arizona State University Zeigler professor proposed parallel discrete event system modularization modeling specification PDEVS(ParallelDiscreteEventSystemSpecifications in 2000)
[4].PDEVS comprises atomic model and coupling model two normal forms.How atomic model normal form regulation grows out of nothing structure minimodel, and coupling model normal form specifies the model that how to utilize the structure of existing atomic model or coupling model hierarchy type larger.But because PDEVS specification is too complicated, and the event handling logic of atomic model is too concentrated, and operational efficiency is undesirable, is not therefore up to the present accepted extensively by industry.
3, based on the Reusable Model development approach of modeling environment
Simulation modeling environment is that reusable realistic model provides operation support platform, and modeling personnel can make full use of the feature of platform, builds the reusable realistic model of simulation modeling environmental interior.But based on the Reusable Model of simulation modeling environment owing to binding with concrete platform, its scope of reusing is usually limited.
The JSIMS system of one of U.S. army's associative simulation three large project provides a series of support facility, and wherein, the synthetic indicator that common component simulation engine CCSE is JSIMS provides core support service
[5].CCSE has used for reference assembly type idea about modeling, provides entity and assembly two kinds of base class, for the component model of User Exploitation oneself, assembles in entity to assembly, be then applied in the simulation frame of CCSE and go.But in CCSE modeling framework there is efficiency in the communication mode of inter-module announcement order formula, and its modeling pattern is also bound with its emulation platform, the model reusability not between supporting platform.
HLA is proposed by U.S. Department of Defense (DoD) modeling and simulating office, is intended to solve interoperability between numerous Heterogeneous simulation system and reuses problem.But the practice effect of HLA in reusing is unsatisfactory, and main manifestations is as follows
[6]:
(1) granularity of reusing is excessively thick.What HLA supported reuses granularity at analogue system or emulation member of an alliance level, is difficult to meet the demand that level inner model is reused.
(2) HLA itself does not solve model reusability sex chromosome mosaicism.For this reason, SISO proposes basic object Model B OM, attempts to make up HLA and is reusing the deficiency in support.But BOM is mainly used in the modeling of facing assembly model, the support on unified model interface specification and Reusable Model development approach still needs to strengthen.
In a word, unified standard is not yet formed both at home and abroad in reusable Simulation Model Development, and existing reusable Simulation Model Development method or not model reusability between supporting platform, be not suitable for the exploitation of the grade simulated solid model of guiding function, be difficult to the fast Development of model reusability and Simulation Application between the distribution Efficient Development of implementation model and platform.Therefore, little in the urgent need to the degree of coupling between a kind of model and do not deposit reusable realistic model and the development approach thereof of binding with emulation platform.
