Figure 4: MembershipData and Fuzzy Logic System Class Diagram e) System User Interface The main purpose of this application user interface is to enhances the field operator/engineers with less effort to navigate and received maximum desired outcome from the system. The steam package boiler ES Graphical user interface is menu-driven type and are shown in Fig7 below. Functions of the system was carried out with a dynamics simulation process in this research work. Figure 5: System User Interface All manual and auto operations take place on this UI, it shows the window style view of the entire structure of the proposed system. Schematically it shows the drum water quality and feed water quality panels, steam package boiler drum, water level, temperature, flow, pressure, console etc. on its panel. Also, on the menu bar of the application shows the Auto sim button, manual sim button, setting button, system panel dropdown and logout menu button (Figure7). f) Admin and User login Interface This is the interface for both admin authorization and user login to have access to the main application. The UI is design to enable admin to provide his login details before the user (field operator/engineers) can have access the main application. The Exit button is clicked to close the application. When credentials are correct the system gives access to the user to access the main application screen as shown in Figure 8.
