“…However, Z has been successfully used especially for the specification of sequential systems rather than concurrent systems because it lacks notation and timing to model concurrency. A number of researchers have attempted to overcome the difficulties, usually combining Z with some other formalism such as Petri Nets [17,27,45], temporal logic [9], and TLA [2] to specify dynamic properties. Recently a number of researchers have taken the route of translating formal specifications in Z or VDM into functional and logic-based languages so that the specification can be executed as a prototype [15,36,38,39].…”

“…The benefits of formal methods and in particular formal specification technique are well documented [12]. A general framework for the specification of concurrent and reactive systems in the formal specification language Z has been presented in [4,13]. We know only of very few attempts (e.g.…”

AbstractͶAs a case study, An Automated Teller Machine (ATM) is a safety-critical and real time system. According to requirements of ATM system we have different machine state status, and four different operations: Withdrawal, Deposit, Transfer, and Inquiry. A key part of early design phases are specifications, which span from requirement, to functional, to design, specifications. This paper describes the conceptual and formal models of the ATM. The formal model of the ATM is specified by using formal specification language. We have used the proper specification language i.e. Z notation. For writing the Z-schemas and the notations we have used the Z-word tool. Which support almost all Z symbols are on the Z-Palette. This model is finally checked using Z/EVES toolset. Therefore this paper attempts to formalize an event-based automation system using formal specification method.

“…The system state is , t = 2 n , 1. In the refinement, we assume that an assignment statement and a tail-recursive call (equivalent to a loop branch-back) take one unit of time each, and that no other operations take any time.…”

“…For the timing case study in Section 3, we use the real-time Z extension described in [3]; alternatives are listed in the references [1,2]. In this approach, Z specifications are extended with fresh variables t and t 0 , which express the time when a computation starts and when a computation finishes.…”

“…Translations are defined between formal notations of interest. The translations provide the mechanisms by which a heterogeneous specification can be given a formal semantics using a homogeneous specification, via mapping the original specification into a single-notation formulation 1 . A set of notations and translations between them, which is to be used to give a formal semantics to heterogeneous specifications, is called a heterogeneous basis.…”

Abstract. We contrast using a notation extension with using a combination of notations. Specifically, we compare the use of an extended dialect of Z [10] with a combination of Z and predicative programming notation [6] for algorithm refinement and for reasoning about time and space constraints on systems. We discuss the difficulty of using extended notations versus using heterogeneous notations, and consider when we might prefer to extend or combine notations. We conclude that there exist situations where a heterogeneous notation can be more appropriate to use than an extended notation.
