A design support method includes: acquiring reference diagrams which are control logic diagrams created in the past, and an editing object diagram; and applying each of analysis rules to each control logic diagram, and analyzing the control logic part included in each control logic diagram. The analysis rules satisfy a relation in which a control logic part corresponding to an analysis rule at a higher hierarchy level contains a control logic part corresponding to an analysis rule at a lower hierarchy level. The design support method further includes: specifying, as a similar diagram, a reference diagram including a control logic part common with the control logic part included in the editing object diagram, among the reference diagrams, based on an analysis result; and presenting a control logic part having a hierarchical relation with the common control logic part, among control logic parts included in the similar diagram.

A control logic diagram analysis device that efficiently creates a control logic diagram, and a method thereof. The control logic diagram analysis device includes a control logic diagram analysis rule application unit, a control logic diagram template component generation unit, and a control logic diagram project-specific part extraction unit. The control logic diagram analysis rule application unit sequentially applies a control logic diagram analysis rule to the control logic diagram from a lower layer level. The control logic diagram template component generation unit acquires the control logic diagram analysis rule having an agreement section within the control logic diagram. The control logic diagram project-specific part extraction unit extracts an element in the control logic diagram corresponding to the control logic diagram analysis rule having the agreement section within the control logic diagram.

An apparatus includes: a similar plant information retrieval unit retrieving plant information of a similar plant similar to a creation object plant from plant information versus control logic diagram association information stored in a plant information versus control logic diagram association information storage unit; a plant information difference detector comparing the plant information of the creation object plant with the plant information of the similar plant to acquire difference information; a plant information editor that, based on the difference information, deletes an element included in the similar plant but unnecessary for the creation object plant, and retrieves an element included in the creation object plant but not included in the similar plant from the plant information versus control logic diagram association information storage unit to add the retrieved element; and a plant information editing result display displaying a result of the plant information editor.

Control logic diagram creation support apparatus

A message sequence generation method and a message sequence generation device, by which a message sequence with an error handling added thereto can be efficiently generated. The method includes setting an action for a specific phenomenon in the phenomenon causal relationship model, associating each element included in the message sequence information with each phenomenon to generate element/phenomenon correspondence information, storing the element/phenomenon correspondence information into a memory device, and acquiring the action set for the phenomenon corresponding to each element and the action set for another phenomenon caused by the phenomenon, from the element/phenomenon correspondence information, and adding the actions to the element as an error handling.
