          4.3.1 Model Base                                                                      Notes

          A collection of pre-programmed quantitative models (e.g., statistical, financial, optimization)
          organized as a single unit. Four categories of models with the model base:

               Strategic models
               Tactical models
               Operational models

               Analytical models
          Strategic Models: Models that represent problems for the strategic level (i.e., executive level) of
          management.
          Tactical Models: Models that represent problems for the tactical level (i.e., mid-level) of
          management.
          Operational Models: Models that represent problems for the operational level of management.
          Analytical Models: Mathematical models into which data are loaded for analysis.




              Task  Make distinction between Tactical models and Operational models.

          4.3.2 Model Building Blocks and Routines

          Model building blocks are Pre-programmed software elements that can be used to build
          computerized models.


                 Example: A random-number generator can be employed in the construction of a
          simulation model.

          Model Base Management System

          MBMS software has four main functions:

               Model creation, using programming languages, DSS tools and/or subroutines, and other
               building blocks
               Generation of new routines and reports

               Model updating and changing
               Model data manipulation

          4.3.3 Model Directory

               Model execution is the process of controlling the actual running of the model
               Model integration involves combining the operations of several models when needed

               A model command processor is used to accept and interpret modeling instructions from
               the user interface component and route them to the MBMS, model execution, or integration
               functions
