Applying Game Theoretic Approach to Goal-Driven Requirements Trade-Off Analysis for Self-Adaptation

A self-adaptive software aims at adjusting itself in response to changes at runtime while considering several important factors. To do this task, such a system should realize the adaptation process, which consists of four phases. Among those phases, we just focus on the deciding (planning) process, especially addressing adequate reflection of requirements to adaptation. In this paper, we represent the arising requirements trade-off problem in terms of goal oriented requirements engineering while adapting to the changes. In addition we apply a game theoretical approach which gives us an insight into analyzing conflicts among requirements. It could provide self-adaptive software with the rationale behind selecting adaptation behaviors.
