It is not feasible to engineer requirements for adaptable and open service-oriented systems (AOSS) by specifying stakeholders’ expectations in detail during system development. Openness and adaptability allow new services to appear at runtime so that ways in, and degrees to which the initial functional and nonfunctional requirements will be satisfied may vary at runtime. To…
Allocation of goal responsibilities to agent roles in Multi-Agent Systems (MAS) influence the degree to which these systems satisfy nonfunctional requirements. This paper proposes a systematic approach that starts from nonfunctional requirements identification and moves towards agent role definition guided by the degree of nonfunctional requirements satisfaction. The approach relies on goal-dependencies to allow potential…
Initial software quality requirements tend to be imprecise, subjective, idealistic, and context-specific. An extended characterization of the common Softgoal concept is proposed for representing and reasoning about such requirements during the early stages of the requirements engineering process. The types of information often implicitly contained in a Softgoal instance are highlighted to allow richer requirements…
Representation and reasoning about information system (IS) requirements is facilitated with the use of goal models to describe the desired and undesired IS behaviors. One difficulty in building and using goal models is in knowing why a model instance is as it is at some point of the requirements engineering (RE) process. If justifications for…
The model identifies constructs that enable capturing the intrinsic characteristics of an agent system such as autonomy, intentionality, sociality, identity and boundary, or rational self- interest; an agent being an organizational actor and/or a software component. Such an approach of the concept of agent allows the analyst to have a holistic perspective integrating human and…
This paper proposes an agent-oriented metamodel that provides rigorous concepts for conducting enterprise modelling. The aim is to allow analysts to produce an enterprise model that precisely captures the knowledge of an organization and of its business processes so that an agent-oriented requirements specification of the system-to-be and its operational corporate environment can be derived…
