This book constitutes the refereed proceedings from the 15th International Conference on Formal
Aspects of Component Software FACS 2018 held in Pohang South Korea in October 2018. The 14
full papers presented together with an invited abstract and an invited paper were carefully
reviewed and selected from 32 submissions. FACS 2016 is concerned with how formal methods can
be used to make component-based and service-oriented software development succeed. Formal
methods have provided a foundation for component-based software by successfully addressing
challenging issues such as mathematical models for components composition and adaptation or
rigorous approaches to verification deployment testing and certification.
