Software Size Estimation for Embedded Software using COSMIC Functional Size Measurement Thandar Zaw Swe Zin Hlaing Myint Myint Lwin Koichiro Ochimizu Software sizing estimates the probable size of a piece of software while effort estimation predicts the effort needed to build it. Measurement of software size from user requirements is crucial for the estimation of the developmental time and effort. The generated Function Point methods are designed for business application domain but it is difficult to estimate the real-time software domain such as embedded software system. Therefore, COSMIC Functional Size Measurement (FSM) method is applied to design both in the business application software domain and the real-time software domain. To correctly measure the functional size of embedded system’s requirements documented and modelled by using the popular tools, FSM procedures must be designed and well defined in embedded system development. Firstly, this paper proposes SysML design notations which can be used to estimate the size of embedded software. After that these design notations can be applied to the COSMIC FSM. SysML representation involves sequence diagram to represent the functional requirements. This proposal uses one of the embedded systems. It shows the usage of SysML sequence diagram with COSMIC FSM which is applicable to the case study in elevator control system. SysML sequence meta model can be defined depending upon the SysML design diagram by extending stereotype through the specific profiling mechanism .Finally, the mapping rules between the meta model and COSMIC FSM define to support the functional size measurement of software. 2016-12-10 http://hdl.handle.net/20.500.12678/0000007962 https://meral.edu.mm/records/7962
