Resolving feature dependency implementations inconsistencies during product derivation

Abstract

Features implementing the functionality in a software product line (SPL) often interact and depend on each other. It is hard to maintain the consistency between feature dependencies on the model level and the actual implementation over time, resulting in inconsistency during product derivation. We describe our initial results when working with feature dependency implementations and the related inconsistencies in actual code. Our aim is to improve consistency checking during product derivation. We have provided tool support for maintaining consistency between feature dependency implementations on both model and code levels in a product line. The tool chain supports the consistency checking on both the domain engineering and the application levels between actual code and models. We report our experience of managing feature dependency consistency in the context of an existing scientific calculator product line.

Surface Modification of Polyethylene Terephthalate Track-Etched Membranes by 2,2,3,3,4,4,5,5,6,6,7,7- Dodecafluoroheptyl Acrylate for Application in Water Desalination by Direct Contact Membrane Distillation

“…The polymeric membranes most commonly used are poly(vinylidene fluoride) (PVDF), polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), polydimethylsiloxane (PDMS), and poly(ethylene terephthalate) (PET) [16]. MD membranes can be produced using various methods, such as track etching, stretching, phase inversion, electrospinning, and combinations of different methods [17,18].…”
