Model Neutral Data Representation
Phone: (617) 273-3388
In Phase I, ALPHATECH will define a model-neutral data structure and supporting access mechanisms that will provide interoperability between different modeling methodologies in support of large scale systems engineering. The model-neutral data structure will provide a common data representation of the model-specific data that is contained in the different modeling methods. The access mechanisms will provide both static and dynamic data access and exchange structural and input parameter data within the modeling environment; dynamic access and exchange will allow models to exchange data during model execution and update input parameters from internal and external data sources within a network environment. In addition, we will conduct a paper study to demonstrate the validity of the model-neutral data structure by applying the defined data structures to exchange data between three modeling methods. In Phase II, we will develop a full-scale implementation of the model-neutral data structure and accompanying access methods. We will apply the resulting software to a sample problem involving at least three different modeling techniques implemented in computer-based tools. The sample problem will be used to determine measures of interoperability.
