Abstract

Goal Model are widely used to capture system goals and refine them into operational requirements assigned to human, hardware or software. Such models support alternative goal refinements resulting in a potentially large design space to explore. A given design can be quantitatively evaluated in terms of its fulfilment of a set of non-functional requirements (e.g. reliability, performance) or business goals (e.g. costs, stakeholder satisfaction). Optimisation techniques can be used to explore the design space to determine an optimal design according to a single objective like the cost but also according to multi-objective techniques to propose a set of Pareto-optimal solutions in which a best solution can be selected. In this paper, we show how to translate a goal-oriented requirements model, expressed in the KAOS notation, into a constraint programming (CP) problem. The OscaR.CP engine is used to get, from all alternatives co explored, either global or Pareto-optimal solutions. Our method is implemented as a tool plugin of a requirements engineering platform and is benchmarked on the classical meeting scheduler case study.
