The process of software development is a structure imposed on developing a software product. The necessity of choosing and following a formal process for developing software is to provide the desired discipline for delivering a quality product for organization success and to avoid waste of money, time, demoralization in developers and more.
It is a common fact that software and computer are a part of people’s existence nowadays, be it in educational aspect, professional and personal aspect. These devices have made people’s lives easy and accurate from retail market to rocket science. The methods are faster, more accurate and cost effective. They have a lot of synonyms since they are engineered under the chosen formal techniques to enhance product quality.
The lifecycle in developing solutions faces many challenges during every phase, and the biggest challenge would be from where to begin. Society is still becoming more dependent on computer systems. As a result, errors in the computer systems could have serious consequences; huge monetary damage could occur or even endangering human lives. In these instances, traditional error prevention methods are insufficient. Nevertheless, employing formal methods could help achieve the safety level desired.
The conventional methodologies in the system engineering are mathematical techniques which are used in designing, implementing and testing frameworks. The application of mathematical methodologies in developing and verification of a package is very labor comprehensive, thus costly. That is why it isn’t feasible to check all the wanted properties of a complete program in detail. The more cost effective way would be to first determine what the crucial components of the program are. The parts could then be separated and studied in detail through creating mathematical models of the sections and verifying them.
Two of the formal methods include the model checking and theorem proving. The first takes a finite transition system and checks if all the properties desired hold for every state of the system in a systematic manner. Since the number of states exponentially grows with the model size, this methodology would often have to limit itself to small variants of the system that’s under investigation. An advantage of this process is that when it finds an issue, it could indicate how it got into an error stage. The information could be used to enhancing the model.
The second method is the theorem that uses general mathematical techniques. This makes it possible to reason regarding systems of which the number states are unlimited. There is a price paid for this and that is the reasoning could not happen fully automatically. By combining the model checking’s strong points, finding counter examples and automation, with more general mathematical power of theorem proving, it takes less effort to guarantee the investigated systems’ reliability. The theory running through the various parts of the thesis is the software surgery methodology in which vital program components are investigated, enhanced and verified using the formal methods mentioned earlier. The verified models could be used to derive computer programs that could satisfy high reliability demands. To know more click here..
