Description
Technical field
The invention belongs to Computer Simulation and modeling field, in particular to a kind of multi-person synergy modeling, it is related to
And to the lifecycle management of model data.
Background technology
Modelica is a kind of brand-new multidomain uniform modeling language of opening that international emulation circle proposed in 1997, it
Conclude and unified previous multi-modeling language, and merged the non-causal idea about modeling of bond graph, Java language towards right
As technology and the numerical value and matrix mechanism of Matlab, thus possesses extremely powerful modeling function.Object orientedness and non-causal
Property is Modelica language biggest advantage.Object -Oriented Model method has the spies such as data encapsulation, layering, connection and succession
Levy, it is easy to which that reduces mistake occurs and the easily reuse of implementation model.So-called non-causality modeling, is exactly with a kind of neutrality, certainly
Right form expression model equation, computation sequences are considered from without more, it is to avoid the cumbersome derivation to model equation, from
And modeling efficiency is improve, and make partial model be easy to be reused.Modelica language is using statement formula, based on equation
Non-causal modeling method sets up model, by defining interface, standardizes model interface, thus use Modelica to model can be with
Make to be completely independent between each subsystem of physical system and can unify mutually.
At present, Modelica is by Audi, BMW, Daimler, Ford, Toyota, masses, German Aerospace Center, France
The different industries such as Air Passenger, Siemens, Electricite De France, ABB company is used, and is widely used in automobile, aviation, energy
The modeling and simulation of the industries such as source, electric power, electronics, machinery, chemistry, control, fluid or field and embedded system.
But with continuing to develop for Modelica models, modeling has been not merely an own business, and this needs a team
To develop a model, this is accomplished by an instrument that can solve the problem that the management of Modelica model versions.
In complicated Modelica models, general version management management tool（SVN、Git）It is all based on text type
Version management, can only see text view when checking model, it is impossible to the change of live preview model specific component version
This, the efficiency that so works together is just very low.Especially when the Documents Comparison of a model is big, existing version management
Support of the instrument to big file, shows congenital deficiency.
In addition, there is this security mechanism in existing collaborative modeling technology, passing everyone copies a model,
Many potential safety hazards just occur in copy procedure, this unit high to security requirement is particularly important.
