Despite considerable research efforts on handling uncertainty in self-adaptive systems, a
comprehensive understanding of the precise nature of uncertainty is still lacking. This paper …

Abstract iStar is a general-purpose goal-based modelling language used to model
requirements at early and late phases of software development. It has been used in …

When a self-adaptive system detects that its adaptation goals may be compromised, it needs
to determine how to adapt to ensure its goals. To that end, the system can analyze the …

Tabular requirements assist with the specification of software requirements using an “if-then”
paradigm and are supported by many tools. For example, the Requirements Table block in …

Abstract Service robots are increasingly being used to perform missions comprising
dangerous or tedious tasks previously executed by humans. However, their users—who …

Software systems are deployed in environments that keep changing over time. They should
therefore adapt to changing conditions to meet their requirements. The satisfaction rate of …

There has been considerable development in the domain of dependability engineering and
analysis in recent decades. The quality guidelines related to dependability attributes such as …

Software requirements (SRs) selection is a multicriteria group decision making (MCGDM)
problem whose objective is to select the SRs from the pool of the requirements on the basis …

Software requirements are the expectation of stakeholders which are identified and modeled
by various requirements elicitation and modeling techniques like traditional methods, goal …

Goals are first-class entities in a self-adaptive system (SAS) as they guide the self-
adaptation. A SAS often operates in dynamic and partially unknown environments, which …
