Description
Technical field
Present invention relates generally to modeling and simulation technology fields, and it is visual to refer in particular to a kind of simulation object based on port encapsulation
Melt hair ring border implementation method.
Background technique
Since studying Parallel Discrete Event Simulation technology since the developed countries such as America and Europe the 1990s, phase
After being proposed multiple Parallel Discrete Event Simulation run time infrastructure, such as SPEEDES, Parsec, YH-SUPE.These are parallel
Discrete events simulation back-up environment is widely used in large scale ecological environmental simulation, computational system biology emulation, country and state
It is complication system and complexity problem in the complication systems Simulation Applications such as anti-strategic research, crisis prediction and warning and disposition decision
Research provide important scientific experiment Method and kit for.
Parallel Discrete Event Simulation (PDES, Parallel Discrete Event Simulation) uses event-driven
Modeling pattern, each simulation object (Simulation Object) of complicated composition system is modeled, between simulation object lead to
It crosses event scheduling and realizes data exchange and communication, entire analogue system is handled by concurrent event and promoted.Based on parallel from
Dissipate event simulation technology scale complex system Simulation Application composed structure as shown in Figure 1, this kind of Simulation Application often by
A large amount of simulation object is constituted, and the realization of each simulation object is by an initialization function (Initial Function) and more
A event handling function (Event Handling Function) is constituted.Wherein, initialization function be used for simulation object into
Row initialization process, event handling function inside include multiple Simulation Calculations (Simulation Computational
Model), realize that the behavior of simulation object handles logic by dispatching the execution of these Simulation Calculations.
With deepening continuously for complication system Simulation Application, the scale of simulation object is increasing, what simulation object included
Simulation Calculation becomes increasingly complex, and the model information needed to configure is more and more, due to lacking intuitive, efficient simulation calculation
Model assemble method, leads to that the development efficiency of simulation object is low, difficulty is big.Secondly, these simulation objects often relate to it is numerous not
The professional knowledge of same domain, and there is complicated interactive relation between simulation object, this just needs different field expert to assist jointly
Quotient is just able to achieve simulation object built-in function and external interactive relation, to be difficult to meet simulation object distribution stand-alone development
Demand.Simultaneously as the continuous variation of complication system simulation analysis demand, this kind of Simulation Application needs continuous integrated emulation pair
As simulation developer is often desirable to the simulation object that will have been developed reuse into this kind of Simulation Application with contracting in this process
The short application and development period, and reuse these simulation objects and be intended to modify its external interactive relation having had been carried out, increase
Big reuse workload of the simulation object between different Simulation Applications.Therefore, complication system Simulation Application Efficient Development is realized
Key points and difficulties are how intuitive, quick, independently developed simulation object, and its zero between different Simulation Applications is supported to repair
Change reuse.
The development approach of traditional " piling up code " formula generally requires simulation modeling personnel, and to study parallel discrete event in depth imitative
Genuine basic theoretical knowledge, it is skilled to grasp Parallel Discrete Event Simulation related platform technology, lead to the exploitation threshold of simulation object
Height, period are long.Visual development technology has abstraction hierarchy more higher than code and closer to Problem Areas, is imitated using existing
True computation model visual assembly is at simulation object, and the Parallel Discrete Event Simulations technology such as shield parallel processing, event scheduling
Details improves development efficiency so as to which the exploitation threshold of complication system Simulation Application is effectively reduced.In recent years, right both at home and abroad
Parallel Discrete Event Simulation visual development technology is paid much attention to, and multinomial achievement, including FLAMES, Pave, VisKit are achieved
Deng.
FLAMES(Flexible Analysis, Modeling and Exercise System) it is U.S. Ternion
A commercialized simplation visualizing integrated system that company releases.Simulation modeling personnel are by directly inheriting what FLAMES was provided
Model base class hand-coding realizes specific simulation object event handling logic.Shortcoming, which is that, to be unable to satisfy and will have
Computation model visual assembly is the demand of simulation object, and the coupling of the simulation object based on FLAMES is close, it is difficult to will
The simulation object developed is reused into multiple and different Simulation Applications.
Pave(Parsec Visual Environment) it is a kind of imitating towards Parsec platform that U.S. UCLA is proposed
Really apply visual development environment.Pave uses controlling stream graph CFG(Control Flow Graph) it is used as discrete events simulation
The visual description normal form of system, uses artificial physical as basic modeling element.However its shortcoming is that CFG
It is unsuitable for directviewing description discrete event system, and it is simulation object that Pave, which is not able to satisfy using existing computation model visual assembly,
Demand；And based on the simulation object of Pave exploitation, interactive relation needs to realize in advance, if answering it in different emulation
It is reused with, then the larger workload for needing to modify.
VisKit is the visual development environment towards discrete event system simulation that United States Naval Postgraduate School proposes.
VisKit occurrence diagram modeling normal form in introduce Object -Oriented Model thought, propose monitor occurrence diagram object (LEGO,
Listener Event Graph Objects).LEGO can be used for describing simulation object, between LEGO by monitoring mechanism into
Row interaction.Its shortcoming is that VisKit generally requires manual programming and adds computation model in event handling logic
Scheduling logic is not able to satisfy the demand by computation model visual assembly for simulation object.Meanwhile " monitoring " object need with
" monitored " object occurs in pairs, thus limits the independence and reusability of simulation object.
In short, support the platform environment of simulation object visual development to be among research and development at present, it is existing imitative
True object visual development environment is primarily present the problem of following three aspects:
(1) it is not able to satisfy the demand by Simulation Calculation visual assembly for simulation object；
(2) it is not able to satisfy the demand of simulation object distribution stand-alone development；
(3) it is not able to satisfy the simulation object demand that zero modification reuses in different Simulation Applications.
Therefore, there is an urgent need to a kind of new simulation object visual development environment, to promote complication system Simulation Application
Development.
