Description
Technical field
The present invention relates to the modeling and simulation technical field, be specifically related to a kind of reusable realistic model and exploitation and using method.
Background technology
Complication system emulation often comprises a large amount of entities; in entity, comprise again a plurality of models, and these models often relate to numerous specialties, need and numerous R&D institution cooperates; in order to protect the intellectual property, model is often submitted to the user with packaged actuating code form.Owing to lacking unified reusable Simulation Model Development standard and the guidance of development approach, interface disunity, the model coupling degree that causes the model of the exploitation of commensurate not outwards to provide be large, with the emulation platform binding closely, make the integrated difficulty of realistic model large, model reuses difficulty.Simultaneously, along with deepening continuously of Simulation Application, the complication system Solid simulation model presents that quantity is huge, of a great variety, the trend of mutual complexity; And, on the one hand, along with deepening continuously and the appearance of complication system ingredient new feature of people understanding, department pattern in the complication system Simulation Application often needs constantly perfect, even develop new model, this just requires the degree of coupling between the reduce model, reduces the impact of model modification on other model, to realize that zero of a large amount of other models are revised, reuses; On the other hand, people often wish that the Simulation model reuse that will develop has to other in analogue system that needs (as certain early warning radar model is applied in different operation simulating experimental systems), and this not only requires model coupling degree little, but also requires realistic model with emulation platform, not bind.
It is the important channel of improving Simulation Application system development efficiency that model is reused, after the Building of Simulation Model of Reuse-oriented, without or only need do a small amount of the modification and just can directly in new Simulation Application, reuse, thereby avoided the overlapping development of low level, improved the development efficiency of Simulation Application, in addition, the model of realizing based on the unified interface standard is also reused and will be brought following benefit
[1]: (1) is encapsulated into the knowledge with domain-specific in Reusable Model, make in the process that builds Simulation Application, the application developer only need be integrated into these models in corresponding simulation frame, without the domain-specific knowledge that the concern model relates to, so just can reduce the exploitation threshold of Simulation Application; (2) by setting up corresponding model bank, Reusable Model is carried out to unified management, break the restriction of professional domain, realize sharing and reusing of each class model resource, reduce the development and maintenance cost of Simulation Application.
The research of reusing for model at present mainly comprises following direction:
1, based on the Reusable Model development approach of modeling language
Modeling language is special Simulation-Oriented Modeling and Design, its principle is normally modeling primitive by the copying modular design of specific area, the scheduling of emulation and control module are designed to emulator, bottom layer realization the automatic mapping function of modeling language to universal programming language.Modeling language has been realized separating of model and emulator, greatly reduces the modeling difficulty, has improved the reusability of realistic model.Yet, modeling language does not have field independence usually, as the ACSL language towards continuous system simulation, towards the GPSS language of discrete event system simulation, the Modelica language of multi-domain Oriented physical simulation etc., towards the multi-field Simulation Application of complication system the time, modeling language exists inborn deficiency
[2].
2, based on the Reusable Model development approach of modeling standard
The simulation modeling standard is that realistic model has defined unified inner structure, behavior and external interface, makes realistic model after having developed, without or only need do a small amount of the modification and just can directly in new Simulation Application, reuse.Usually the simulation modeling standard does not limit concrete programming language and operation support platform, can build reusable realistic model be used to instructing.
Ou Hang office (ESA) has proposed the realistic model of Reuse-oriented and has described standard SMP2(Simulation ModelPortability Standards2 in 2004)
[3].The purpose of SMP2 standard is to provide a model development framework, and, cross-platform reuse independent with the platform of realizing realistic model adopt the thought of component-based to support the modularization of realistic model and service of simulation to design.But SMP2 standard abstraction hierarchy is higher, is not suitable for the exploitation of guiding function level, low level realistic model.
Arizona State University Zeigler professor has proposed parallel discrete event system modularization modeling standard PDEVS(Parallel Discrete Event System Specifications in 2000)
[4].PDEVS comprises atomic model and two normal forms of coupling model.The atomic model normal form stipulates how to grow out of nothing the structure minimodel, and how coupling model normal form regulation utilizes the larger model of structure of existing atomic model or coupling model hierarchy type.But because the PDEVS standard is too complicated, and the event handling logic of atomic model is too concentrated, and operational efficiency is undesirable, therefore up to the present by industry, is not accepted extensively.
3, based on the Reusable Model development approach of modeling environment
The simulation modeling environment provides operation support platform for reusable realistic model, and the modeling personnel can take full advantage of the characteristics of platform, builds the reusable realistic model of simulation modeling environment inside.Yet due to the binding of the platform with concrete, its scope of reusing is usually limited based on the Reusable Model of simulation modeling environment.
The JSIMS system of one of U.S. army's associative simulation three large projects provides a series of support facilities, and wherein, common component simulation engine CCSE provides the core support service for the comprehensive battlefield surroundings of JSIMS
[5].CCSE has used for reference the assembly type idea about modeling, provides entity and assembly two kinds of base class, for the component model of User Exploitation oneself, in entity, assembly is assembled, and then is applied in the simulation frame of CCSE and goes.But there is efficiency in the communication mode that in the CCSE modeling framework, inter-module is announced the order formula, and its modeling pattern also with its emulation platform binding, the model between supporting platform is not reused.
HLA is proposed by modeling and simulating office of U.S. Department of Defense (DoD), is intended to solve the interoperability between numerous Heterogeneous simulation systems and reuses problem.But the practice effect of HLA aspect 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 the level inner model is reused.
(2) HLA itself does not solve model reusability problem.For this reason, SISO has proposed basic object Model B OM, attempts to make up HLA in the deficiency of reusing in support.But BOM is mainly used in the modeling of facing assembly model, and the support on unified model interface specification and Reusable Model development approach still needs to strengthen.
In a word, aspect reusable Simulation Model Development, not yet forming unified standard both at home and abroad, and existing reusable Simulation Model Development method otherwise not between supporting platform model reuse, be not suitable for the exploitation of the grade simulated solid model of guiding function, be difficult to model between the distribution Efficient Development of implementation model and platform and reuse the fast Development with Simulation Application.Therefore, little in the urgent need to a kind of model coupling degree and do not deposit reusable realistic model and the development approach thereof of binding with emulation platform.
