Solution Mapping

The total budget must be split into a software budget and hardware budget.

The hardware budget is used to purchase devices that produce resources.

The software budget purchases components that consume resources provided by hardware

A valid solution mapping occurs when purchases are within budget and no item consumes more resources than are present.

Solution Approach Multi-model configuration space exploration with ASCENT

•The Allocation-baSed Configuration ExploratioN Technique (ASCENT) uses a heuristic technique to explore a configuration solution space to find cost-optimal design configurations

•We will use ASCENT to combine & explore budget, hardware variability, software variability, & resource consumption models to produce upgrade recommendations

•ASCENT will also produce a graph of key cost-based trends in the configuration solution space

Solution Approach for Configuration Space Exploration

Hardware and software items are split into sets. Only one item is chosen from each set. The items chosen determine the overall value of the

configuration.
