Graphical user interface device

A graphical user interface device in a monitoring and control system that monitors and controls a plant, the graphical user interface device comprising:

• a memory device in which pieces of operation manual data including descriptions regarding operation targets and operation details are registered, the descriptions being arranged in an order of operation procedure;
• a database in which device IDs indicating devices being said operation targets and operation IDs indicating said operation details are registered;
• and
• an operation model creating device automatically creating, from said operation manual data, operation procedure template data including information of one or multiple operation procedures and device IDs and operation IDs corresponding to respective procedures of the operation procedure for each type of a handling operation to register the operation procedure template data in the memory device,
• wherein the graphical user interface device is configured to select, by a pattern matching processing of said operation procedure template data and plant measurement data including device IDs and operation IDs respectively corresponding to multiple immediately-preceding successive operations, operation procedure template data having a high degree of coincidence with said immediately preceding operation, and estimate a type of a handling operation currently executed by an operator and subsequent operation details, to thereby display, on a display section of said monitoring and control system, guidance information based on a device ID and an operation ID corresponding to the estimated subsequent operation details.
