“…Compared to model checking, SMC is simple to implement, understand and use, and it requires no specific modeling effort other than a system model that can be simulated and checked against quantitative properties. In fact, SMC is more and more being applied in industry [38]- [50].…”

“…Over the last 25 years, Formal Methods have been successfully used in the development of systems. As experts confirm in the Survey on Formal Methods (Garavel et al, 2020), the application of formal methods provides multiple benefits, such as quality, security, and easier maintenance. However, their adoption in the software industry still faces some obstacles such as the lack of efficient support tools and methods (Steffen, 2017).…”

Formal methods provide multiple benefits when applied in the software development process. For instance, they enable engineers to verify and validate models before working on their implementation, leading to earlier detection of design defects. However, most of them lack flexibility to be applied in agile software development projects. Alloy is a lightweight formal modeling language with a friendly tool that facilitates the agile approaches application. Unfortunately, its industrial adoption is hampered by the lack of methods and tools for current software development frameworks, such as Entity Framework. This platform is usually chosen by agile projects following the code-first approach that allows automatic generation of a database from domain classes coded in the C# language. We present a new method and tool for the formal specification and analysis of Entity Framework projects with Alloy. The proposal allows engineers to start the software development using Alloy for modeling, validation and verification, automatically translate Alloy specifications to C# domain classes and then generate the corresponding database with Entity Framework. We validate our approach with a real case study: an application required by a gas supplier company.

“…From long time the use of models and formal analysis techniques is highly demanded already at design-time to improve software quality and guarantee safety, reliability, and other desired qualities. However, the usage of formal methods in industrial projects is still limited [3,20,21] and practitioners are still skeptical in using formal methods since they are considered time-consuming approaches that do not fit into an agile continuous integration development process.…”

Rigorous development processes aim to be effective in developing critical systems, especially if failures can have catastrophic consequences for humans and the environment. Such processes generally rely on formal methods, which can guarantee, thanks to their mathematical foundation, model preciseness, and properties assurance. However, they are rarely adopted in practice.In this paper, we report our experience in using the Abstract State Machine formal method and the ASMETA framework in developing a prototype of the control software of the MVM (Mechanical Ventilator Milano), a mechanical lung ventilator that has been designed, successfully certified, and deployed during the COVID-19 pandemic. Due to time constraints and lack of skills, no formal method was applied for the MVM project. However, we here want to assess the feasibility of developing (part of) the ventilator by using a formal method-based approach.Our development process starts from a high-level formal specification of the system to describe the MVM main operation modes. Then, through a sequence of refined models, all the other requirements are captured, up to a level in which a C++ implementation of a prototype of the MVM controller is automatically generated from the model, and tested. Along the process, at each refinement level, different model validation and verification activities are performed, and each refined model is proved to be a correct refinement of the previous level. By means of the MVM case study, we evaluate the effectiveness and usability of our formal approach.
