Spreadsheet algorithms are modeled using spreadsheet
programs in computers. In these type of problems
Network Simulation involves simulation of stochastic
network. These types of models
If the algorithm produces the mathematically best solution
it is called optimal (or exact) if it produces a good
but not necessarily best solution it is called heuristic.
Expert systems are computer programs which are programmed
with qualitative and quantitative knowledge about a real-world
system. When a specific case is presented the system makes use
of its preprogrammed "experience" to suggest solutions.
These are
It appears that different models with different levels of detail
and realism are appropriate and useful at different stages of
the design process. Systematically increasing the level of model
complexity for the same problem and evaluating their solutions
and their consistency provides a way to eliminate the models.
This successive refinement approach is a primal approach with
the advantage that an approximately feasible solution exists if
the solution process has to be terminated prematurely.
