An apparatus comprising: a procedure progress database in which progress status and identification information of a relevant member are recorded for each of pieces of work; a team status evaluation unit which identifies a member requiring support on work in the monitoring and control within a team; an operation support content determination processing unit which determines, as support content, information on the possibility of substitution by a member having the operation authority for the work that the identified member is scheduled to perform; and a presentation information generation processing unit which selects a plurality of persons including the identified member as presentation targets of the determined support content, and generates presentation information in accordance with each of the selected persons.

Plant monitoring and control apparatus and plant monitoring and control method

Provided are an index value calculator to calculate an index value obtained by quantifying a degree of status for evaluation items, a teamwork evaluator to evaluate a teamwork based on the index value, a support content determiner to select target persons to be supported including the members of the team based on the evaluation result of the teamwork and determine support contents in accordance with the target persons to be supported, and a presentation information generator to generate presentation information for presenting the determined support contents for each of the output devices corresponding to the selected target persons to be supported, and the teamwork evaluator evaluates the teamwork using an evaluation logic configured by combining logical formulas for comparing a threshold value set for evaluation items with the calculated index value.

The vulnerability influence evaluation system includes: a vulnerability information storage unit which stores vulnerability information; a vulnerability information collecting unit which collects the latest vulnerability information from the vulnerability information storage unit; a system relevance determination unit which compares system definition information about an evaluation target system with the vulnerability information, and determines whether or not there is relevance between the evaluation target system and vulnerability; a vulnerability influence degree calculation unit which calculates the vulnerability influence degree of vulnerability relevant to the evaluation target system on the basis of vulnerability influence degree calculation information; a vulnerability influence degree determination unit which performs determination as to the vulnerability level of the evaluation target system on the basis of the vulnerability influence degree; and an evaluation result output unit which outputs a result of determination by the vulnerability influence degree determination unit.

Vulnerability influence evaluation system

This test device for a monitoring control device includes an input/output controller, a logic controller, a logic connector, a logic executing simulator, a test target indication unit, an apparatus characteristic receiver, a logic managing simulator, and a logic connection information generator. Using an apparatus characteristic obtained by the apparatus characteristic receiver, the logic managing simulator specifies a simulation logic appropriate for a control logic on the basis of a simulation logic management rule. The logic connector connects the control logic and the simulation logic, by using logic connection information generated on the basis of a logic connection rule.

Test device for monitoring control device

A technique capable of estimating an error point in a logic diagram appropriately. A logic diagram display device includes: a signal line correctness/incorrectness determining unit that determines for each test whether each signal line in the logic diagram is correct or incorrect based on a signal line status value of each signal line and a test table; and a signal line correctness/incorrectness result summarizing unit that calculates a correctness/incorrectness result summarized value of each signal line based on a result of determination about the correctness or incorrectness of each signal line. The logic diagram display device further includes: an error signal line estimating unit that estimates an error in each signal line based on the correctness/incorrectness result summarized value of each signal line; and a display that displays each signal line in the logic diagram in a display style responsive to the error in each signal line.

Device for and method of estimating error point in logic diagram

A logic diagram processing device has a logic diagram relocating unit which relocates operation elements while maintaining control logics equivalently so that the operation elements as compared overlap in the case where a plurality of designated logic diagrams are overlapped, and a logic diagram overlapping unit which overlaps the plurality of designated logic diagrams in which the operation elements are relocated by the logic diagram relocating unit. The logic diagram processing device also includes a display unit which displays the plurality of designated logic diagrams overlapped by the logic diagram overlapping unit in a predetermined display method by which a common part or the difference of the operation elements can be discriminated, and a display control unit which switches the predetermined display method to display in the display unit in accordance with an instruction from the outside.

Logic diagram processing device and logic diagram processing method

Image feature values Va and Vb are derived from image data, coefficients C and D are determined based on the image feature values Va and Vb, and an approximate expression expressed with the file size Sfj of the JPEG compression file and the quantization data coefficient value Aqt is derived. Next, by designating the file size of a desired predetermined JPEG compression file based on the approximate expression, the quantization data coefficient value Aqt is derived, and a first quantization table as a reference is multiplied by the quantization data coefficient value Aqt, whereby a second quantization table is obtained. Then, using the second quantization table, the image data is actually JPEG-compressed.
