Goal-Oriented Model Conversion to Automated Planning Problem Using Hierarchical Task Networks

Abstract

Specifying systems adhering to stakeholders' goals is a topic of great research interest. This scenario becomes even more challenging when it is expected that systems will be able to adapt in a timely manner to the situations experienced by them in order to promote adherence to organizational and individual expectations. In this sense, this papers works with goal-oriented modeling to promote the understanding and requirements' analysis focused on agents' interests. During the systems project, we advocate the use of automated planning to support the selection of requirements or to support the adaptation of its functionalities at runtime. As a first step, this paper provides a goal-oriented automatic model converter (Tropos model) using RGM (Runtime Goal Model) rules for real-time adaptation to a planning model based on hierarchical tasks network. The converter was tested using three generic examples and a real scenario of a mobile application for public transport. The converter was promising and adherent to the representation of reality.
