Most software reliability growth models specify the expected number of failuresexperienced as a function of testing effort or calendar time. However, there areapproaches to model the development of intermediate factors driving failureoccurrences. This paper starts out with presenting a model...

In this paper, we discuss the models of continuous dynamics on the 2-simplex that arise when different qualitative restrictions are imposed on the (continuous) functions that generate the dynamics on the 2-simplex. We consider three types of qualitative restrictions: inequality (or...
