This technique for system representation has a crucial feature of real-time system modeling. It has control and verification of dynamics systems against complex system specifications, which model the fundamental continuous-state dynamics. Human interaction with integrated systems encompasses the user, timed automaton with Z-specification model logic, and establishing concurrency and a distributed structure within the human interaction system. Frequently, the interface of the user for human interaction systems displays the abstract set of information. In safety-critical systems, our desire to recognize the design of interface which can be cumbersome, and it does not have adequate details, or which may surprise the user. We address 1) the technique for scheming the abstraction of a discrete event system for the integration of timed automaton and Z-specification, to analyses, verify, or design user-interfaces for the integration of timed automaton and Z-specification, and 2) the required specification properties beneficial to cracking the non-deterministic choices for usability properties of the interface. Applications is used to progress in formal specification to such a degree that it be in change in the track of proper execution and the development of advancement termed as refinement. To analyze and validate the formal specification, we applied Z notation toolset. We develop the formal model of multiple users, multiple machines, a supervisor and a supervisor machine with the integration of timed automaton and Z-specification, including the user’s input and the automation’s discrete mode-logic. The model’s syntax and semantics are developed using system specification through timed automata. It follows the required formal specification properties for cracking the non-deterministic choices for usability properties of the supervisor and user interface. Further, to develop the correct interface using the tool of weak bi-simulation, in which many classes of potentially identical states merge into a single one, allows the supervisor and user to execute the given task properly. By doing the formal verification using TZ-automaton for safety which stand up using this calculation, we mathematically assurance that this secure section is invariant. This guarantee holds to the accuracy of the model. The process of abstraction could be performed using the discrete event system from TZ-automaton through secure limitations aiding the calculated invariant sections as a discrete state. Our abstraction is useful for comprehensive interface analyses, with current interface formal verification including design techniques. A user-interface, modeled as a discrete system, must not only in smaller but also visible. We originate settings for direct observability, where the recent output generates the current state and last occurring event. We also show how to produce the outcome for inaccessible user-interfaces where it satisfies this property. These methods are beneficial to use the TZ-automaton state-reduction techniques. Our research motivation is useful in our proposed approaches to aircraft, major instances of complex and safety-critical systems. Moreover, to investigative pilot interaction using the aircraft autopilot throughout a landing/go-around operation for a considerable civil jet aircraft. We use the proposed approach in the development of formal specification for manufacturing system using varieties of users interacting using their machines, a supervisor interacting through several users and a supervisor with a supervisor machine to demonstrate the strategy process of human-machine systems. The implementation demonstrates the over-all nature of these techniques, which are applicable for systems which have operative limitations we can propose concerning safety. The abstraction method varies since current research in finite state machine system verification in our handling for user’s interactions with the TZ-automation system. The Z-eves tool-set used for the validation of formal specification.
