AS-TRM and functional size with COSMIC-FFP

Abstract

COSMIC-FFP – ISO 19761 – is a functional size measurement method developed by the Common Software Measurement International Consortium (COSMIC). The COSMIC-FFP measurement model and related definitions are generic, and this paper investigates the feasibility of their application in specification languages. More specifically, it proposes a formalization of the COSMIC-FFP definition for the Autonomic Systems Timed Reactive Object Model (AS-TRM). This would allow the integration of functional complexity and functional size monitoring during autonomic system specification construction and/or evolution. The Steam Boiler case study is introduced to demonstrate the applicability of functional size measurement in terms of AS-TRM modeling.
