  abstract = {Software Product Line Engineering (SPLE) is a successful paradigm
	to produce a family of products for a specific domain. A challenge
	in SPLE is to check that different models used in early SPL specification
	do not contain inconsistent information that may be propagated and
	generate inconsistent products that do not conform to its requirements.
	This challenge is difficult to address due to the high number of
	possible combinations of product features and model fragments specifying
	those features. Variability Consistency Checking (VCC) offers automatic
	means to address that challenge. VCC relates information inferred
	from the relationships between features and from base models related
	to those features. Validating if all the products in an SPL satisfy
	user-defined consistency constraints is based on searching for a
	satisfying assignment of each formula generated by VCC. We validated
	VCC and its supporting tool on two case studies from different application
	domains, the results were encouraging as we did not observed significant
	performance penalties.},
