Abstract

Context

The underlying uncertainty in self-adaptive systems aggravates the complexity of selecting best adaptation action alternative, and handling requirements trade-offs. To efficiently tackle uncertainty, it is necessary to have a comprehensive overview of different types of uncertainty and their specifications.

Objective

In this paper we aim at (a) reviewing the state-of-the-art of architecture-based approaches tackling uncertainty in self-adaptive systems with multiple ...
