Software Stability Model (SSM) for Building Reliable Real Time Computing Systems

With lot of advancements coming up in real time systems, the primary controlling factors like security, reliability and trustworthiness have become key elements of success. Our work is based on the concept of software stability model (SSM) applied to real time computing systems with adaptive reconfigurable controls. The primary factors to ascertain stability of physical systems are `controllability´ and `observability´. The intent of this research is to map these contributing factors of physical system stability to the software stability model (SSM) defined in software engineering. Identifying the design pattern for a domain using software stability model (SSM) helps one apply the design pattern for a different application/problem in the same domain. This has been demonstrated through the design pattern derived for a transaction processing system that involves adaptive reconfigurable controls. We have essentially tried to integrate the software stability model defined in software engineering with control engineering concepts essentially by defining the enduring business themes (EBTs), business objects (BOs) and industrial objects (IOs).
