What the study found
A decision support model based on the Analytic Hierarchy Process (AHP), a structured method for comparing choices, was used to select an application server architecture for CASE tools. In the example described, the “three-tier + modular” configuration received the highest global priority score.
Why the authors say this matters
The authors state that the model can help software architects make a justified architecture choice at the design stage and plan modernization steps for existing systems. They also note that CASE tools particularly need support for collaborative model editing and remote web access.
What the researchers tested
The researchers proposed a six-stage decision support algorithm: defining criteria, weighting them through pairwise comparisons, listing acceptable alternatives, evaluating each alternative by criterion, calculating global priorities, and analyzing transitions between architectures. They applied the model to a practical case involving a desktop CASE tool with a two-tier monolithic architecture.
What worked and what didn't
The global priority calculation showed the three-tier modular option ranked highest among the alternatives considered. The introduction of a threshold for priority differences provided a formal way to justify the transition decision and to determine an order for intermediate migration stages. The abstract does not report detailed performance comparisons beyond this ranking.
What to keep in mind
The summary available here does not describe numerical values, a full list of alternatives, or external validation beyond the demonstrated case. It also does not state specific limitations of the model in the abstract.
Key points
- The study used Analytic Hierarchy Process (AHP) to support architecture selection.
- In the CASE tool example, the three-tier modular configuration ranked highest.
- The model includes six stages, from defining criteria to analyzing architecture transitions.
- A threshold for priority differences was used to justify the transition decision and intermediate migration stages.
- The abstract says the model may help design new systems and modernize existing ones.
