Constructing hybrid software process simulation models

Software process simulation (SPS) has become an active research area for managing and improving software development processes since its introduction in the last two decades. Hybrid simulation, the combination of simulation paradigms to address a problem, is becoming more popular as the problems we are presented with become more complex. However, integrating multiple simulation paradigms faces the issues of compatibility, interoperatability and synchronization when executing simulation. The objective of this research is to present the state-of-the-art of this research area, the hybrid mechanism when integrating paradigms, and more importantly provide practical support for the effective adoption of hybrid simulation in SPS context. Based on an extended systematic literature review, this paper presents the preliminary results by answering the research questions. Depending upon the way these simulation paradigms represent different aspects and levels of software process and the context in which they can be modeled by SPS, two hybrid mechanisms: Hierarchical Mechanism and Interlinked Mechanism, have been frequently employed. The detailed discussions of integration strategies and recommendations when applying hybrid simulation may offer reference value to the SPS community.
