Hybrid Modeling of Test-and-Fix Processes in Incremental Development

Software process simulation modeling has become an increasinglyactive research area for managing and improving software development processessince its introduction in the last two decades. Hybrid process simulationmodels have attracted interest as a possibility to avoid the limitations of applyingsingle modeling method, and more realistically capture complex real-world software processes. This paper presents a hybrid process modeling scheme tobuild an integrated software process model. It focuses on the particular portionof software process by using different techniques on separate but interconnectedphases, while still allows for the integrity of modeling development process.We developed a hybrid simulation model of the test-and-fix process of incrementalsoftware development. Results conclude that this approach can supportthe investigation of portions of software process at different granularity levelssimultaneously. It also avoids the limitation caused by incomplete process detailof some phases, and may help reduce the effort of building a hybrid simulationmodel.
