Software Architecture Design

As the use of software intensive systems increase in our daily lives, the systems are getting larger and larger every day. A significant portion of these software systems in use are medium to large in size and complexity. Most of them are also becoming a part of a system of systems. In addition to satisfying of a set of functional requirements, the users expect a certain level of quality in these systems. Quality requirements are also referred as nonfunctional requirements. Adequate satisfaction of quality requirements can be achieved via a careful software architecture design. Since the quality requirements are multi-faceted, the software architects have to consider many diverse aspects and provide a software architecture solution that can optimally satisfy both functional and nonfunctional requirements. Therefore, such a solution requires a multi-view software architecture design as the result of a careful systematic system development effort. Research reports with detailed case studies are helpful in bridging the gap between academia and industry. Research studies including a carefully designed real-world sample case studies will help practitioners and engineers to understand the theoretical concepts and apply the novel research findings in their practices. Therefore, in this study, we explain the systematic multi-view software architecture design with the help of a detailed mission-critical defense system development case study. The mission critical system in the case study is a Mine Neutralization System for navy mine hunting ships. In the study, we explain the multi-view software system architecture design step by step starting with identifying the system context, requirements, constraints, and quality expectations. We further outline the strategies, techniques, designs, and rationales used to satisfy a diverse set of requirements with a particular software architecture pattern. In addition, we introduce a novel architectural style named as a star-controller architectural style. We explain the use of the style with a related discussion.

To reuse successful experience in software architecture design, architects use architectural patterns as reusable architectural knowledge for architectural synthesis. However, it has been observed that the resulting architecture does not always conform to the initial architectural patterns employed. Architectural synthesis using architectural patterns is also recognized as a challenging task, especially for novice architects due to lack of experience. In this paper, we propose a cooperative coevolution approach to automate architectural synthesis using architectural patterns. We first analyze several common architectural patterns and the constraints when using them. We then extend existing architectural synthesis activity with patterns based on the results of this analysis. Finally, we map the extended architectural synthesis to a cooperative coevolution model, which can optimize the resulting architectural solutions and avoid the violations to the pattern constraints automatically. We evaluate the proposed approach through a case study: architecture design of a cinema booking system. The results show that the proposed approach can generate architectural solutions which are closer to the expert design.

In this paper, we present a transition journey of automotive software architecture design from using legacy approaches and toolchains to employing new modeling capabilities in the recent releases of Matlab/Simulink (M/S). We present the seamless approach that we have employed for the software architecture modeling of a mixed-critical electric powertrain controller which runs on a multi-core hardware platform. With our approach, we can achieve bidirectional traceability along with a powerful authoring process, implement a detailed model-based software architecture design of AUTOSAR system including a detailed data dictionary, and carry out umpteen number of proof-of-concept studies, what-if scenario simulations and performance tuning of safety software. In this context, we discuss an industrial case study employing valuable lessons learned, our experience reports providing novel insights and best practices followed.

Reliability-aware software architecture design has recently been gaining growing attention among software architects. This chapter tackles the issue by proposing an ontology-based, reliability-aware software architecture design and evaluation approach, called OntoArch, which incorporates quantitative reliability evaluation in software architecture design by the means of the OntoArch ontology and the OntoArch tool. The OntoArch approach is characterized by: (1) integration of software reliability engineering and software architecture design; (2) proposing a reliability-aware software architecture design process model; (3) developing the OntoArch ontology in the context of software architecture design and software reliability engineering; and (4) the OntoArch tool not only enabling software architects to design architectures and model reliabilities, but also functioning as a knowledge management platform relying on reliability-aware software architecture design. The OntoArch approach is validated for a software architecture design; for example, Personal Information Repository (PIR), with the use cases of OntoArch-based software architecture knowledge management, software reliability profiling, and software architecture modeling and evaluation.
