In a first aspect, this specification embodiment provides a kind of Modeling Platform system based on graph data structure.It should be based on figure
The Modeling Platform system of data structure constructs object module according to business demand for user, and so-called object module refers to flat
The model constructed on platform, it is accurate in order to state, it is referred to object module.
Fig. 2 is referred to, for the structural schematic diagram of the Modeling Platform system based on graph data structure.As shown in Figure 2, this is
System includes model list module 201, algorithm assembly module 202, graph structure module 203, interpreter module 204 and control centre's mould
Block 205.
The operation principle and process of modules is explained as follows below.
Model list module 201, for storing and showing that model list, model list include at least one preset model.
For meeting the plateform system of financial metering system business demand, model list module 201 is stored and is shown
Model list include but is not limited to following preset model: stochastic interest rate models, bond rate model, Risk Model, phase
Weigh pricing model, Asset Pricing Model etc..These preset models cover the various models of business demand substantially, straight for user
Selecting takes use.
Preset model has been determined, that is, can determine the data structure of model, in modeling process, has also needed to further determine that fortune
The algorithm and operation result of each operator (computing module) in row model, and finally obtain the calculated result of model.
Algorithm assembly module 202, for having stored and having shown each algorithm assembly of various algorithms built-in.
