Formal Modeling of Smart office using Activity Diagram and Non Deterministic Finite Automata

In this era, almost Every person spends 8 to 12 hours in office within a day for the sake of earn money. Offices are considered employees second home as much of the time of employees is spent over there. Employees spent their mental or physical energy to do work in offices and to get money for fulfilments of their desired needs. However, to increase the efficiency and better performance of the employees there are important steps which are followed. The modelling of smart offices provides the system view for understanding and visualizing of office management system from multiple perspectives. In this paper, the modeling and verification of smart office management system is done using UML diagrams, Automata Theory and formal specification language. The operational and behavioral model of the system is captured using UML diagrams. Automata based models are used to provide automated behavior of a system in terms of states. The consistency, accuracy and reliability of the smart office system is done using formal methods. Vienna Development Method and Specification Language (VDM-SL) is used in this paper for verification and validation of the proposed model.
