Functions Offered by MUI

which displays the results of the execution of the user instructions and commands, and W3, which displays the models and model elements in visual form so that user can select interactively from this list to perform any required model manipulation. MUI includes an intelligent parser that provides online syntax options for both the syntax of the instructions and the parameters retrieved from the central model repository. For example, while user is typing Gr system shows a list of instructions that start with Gr i.e. Grant Access (based on the user profile and domain). Once user selects Grant Access , system will type Model Name= , followed by a list of existing model names available in the model repository (based on the user permissions and security levels). Sample functions offered by MUI can be viewed in table 5-2. 

User Instructions Accept user instructions (MML / MQL) User instructions syntax checking (Parsing) 

Results List of model elements for a given selection 

Model Visualization Visualize list of models, metamodel elements, and model elements in a visualized form, whieh also refleet the inheritance among classes 

There are many tools and standards that interact with the plant enterprise models within PEEE. Hence, forcing one standard for model representation may not be a feasible solution. The proposed idea in this context is to enable model translation into different, and common, model representation formats that are commonly used. Examples of such model representation formats are XML, XMl, Express-X, and HTML. The model is basically represented within the plant model repository (MB/MMB) in a neutral and unified format i.e. UML. The model
