Generating Architectures

The generation of alternatives is done by using the Architectures Wizard. This wizard guides the generation of alternatives and consist of three different steps. The actors that are considered for generating the architecture are the ones in the current page.
  • Step 1: Maximum coverage and anchoring. In the first step, the user can set the maximum coverage per actor and the actor anchoring. By setting the maximum coverage per actor, the user constraints the number of COTS that will cover that actor in the architecture. By anchoring an actor, the user sets that the actor is already covered by some software (usually a legacy system or a contractual system, which cannot be modified) and thus kept out of the process.



  • Step 2: Selection of the properties to be evaluated. In the second step, it is possible to choose the properties that are suitable to be taken into account for the evaluation of the current properties.

  • Step 3: Display of the Results. The architecture evaluation are displayed. With this results, the different architectures can be analysed with respect to the values for the properties that are interesting for the system.



  • The wizard generates several architectures according some suggested candidate architectures to be evaluated. The architectures are represented as i* models that are added at the end of the pages list. The name of the pages containing generated architectures generated by the wizard is of the form ‘Arch-#’, where # is the page number.



  • A triangular shape with the name of the architecture is also dropped to the pages, and contains the characteristics of the architectures and the corresponding evaluation. As it can be seen the form has two tabs, on the first one (left) it is possible to see that Comp3 covers both the Mail Server and the Mail Client actor. On the second one (right) it is possible to see the evaluation for the choosing properties.
