“…To accomplish this goal, we will address the area of specification design through the use of formal methods, and show how errors can be eliminated early in development with the use of ATP. This work is an expansion of work already presented in [1,33]. We will also illustrate the development, use, and statistical results for reliable software in safety critical applications.…”

“…Note that any formal method and implementation medium can be utilized for refinement as long as the characteristics of each are well understood and the proof can be completed. In contrast to the original requirements of [33], some additional constraints need to be in place before the refinement can proceed. In particular, the constraints are:…”

“…Software usage is increasing rapidly in all aspects of life and the reliability of these software has become a prime challenge, especially when the safety-critical software [17] are involved where failures often lead to a sudden loss of life, money or valuables. While using an e-banking payment system to make a transaction, it is vital that the software handling the complete process must guarantee the secure end to end transaction as well as the privacy of data to avoid its misuse.…”

Abstract-Formal modeling and verification techniques have been used to ensure the reliability and accuracy of multiple systems to be verified. In contrast to ordinary testing techniques which exhibit the presence of flaws and errors in a system, formal methods prove their absence. Electronic banking (ebanking) services have become very popular with the escalating development in the information and communication technology. Due to the presence of complexity, an e-banking system requires an efficient security model. One important approach to ensure the reliability and security of the e-banking system is through the use of formal methodologies. This study explores the opportunity of modeling interbank payment system through a case study of 1-link Automated Teller Machine (ATM). A generic verification system SPIN (Simple Promela Interpreter) is, therefore, employed to model and then to verify the integrity and security of payment system in e-banking. Linear temporal logic formulas are further summarized to assure the security of the e-banking system. The principal conclusion of the work includes a complete procedure of verification and modeling of the payment system in 1-link ATMs.

“…However it is the strength of using FM that it helps to spot errors during early stages of system development [6] when errors are cheaper and easier to be fixed. Despite of major fallacies prevailing in market about FM, the use of FM is highly recommended for modeling of safety critical systems [9].…”

Agent-based Mobile Petri Net (MPN) is an emerging variant of classical Petri Nets which allows graphical representation of system to be developed. In addition agent-based MPN integrates mobile agent technology for modeling concurrency and mobility. Unified Modeling Language (UML) has become a defacto standard for modeling any real world system. Unlike UML models, MPN are based on mathematical semantics and can be verified for presence of errors and inconsistencies. This paper demonstrates the strength of agent-based MPN to model and verify Air Traffic Control (ATC) which is a complex, highly distributed and safety critical system. Firstly the abstract model of ATC system is introduced by identifying mobile agents like aircraft and controller then the abstract ATC model is transformed into formal ATC model. The three major operations of Takeoff, enroute and landing have been formalized using agentbased MPN. Finally the reachability analysis has been used to verify formal ATC model.
