Abstract In Design by Shopping, designers explore the design space to gain an insight into
trades, and feasible and impractical solutions, as well as to learn about alternatives before …

Testing large-scale systems is expensive in terms of both time and money. Running
simulations early in the process is a proven method of finding the design faults likely to lead …

Recent work with NASA's Jet Propulsion Laboratory has allowed for external access to five
of JPL's real-world requirements models, anonymized to conceal proprietary information, but …

Solutions to non-linear requirements engineering problems may be “brittle”; ie small
changes may dramatically alter solution effectiveness. Hence, it is not enough to just …

Lors de l'exploration d'espace de conception, les données résultantes de la simulation d'un
grand nombre d'alternatives de conception peuvent conduire à la surcharge d'information …

Requirements Engineering (RE) is concerned with the elicitation, evaluation, specification,
analysis and evolution of the requirements on a software-intensive system. Risk analysis at …

Background: Search-based Software Engineering (SBSE) uses a variety of techniques such
as evolutionary algorithms or meta-heuristic searches but lacks a standard baseline method …

Goal optimization has long been a topic of great interest in computer science. The literature
contains many thousands of papers that discuss methods for the search of optimal solutions …

Early life cycle risk models can represent the requirements that a development group would
want to achieve, the risks that could prevent these requirements from being met, and …
