Protocol evaluation support apparatus and protocol evaluation support method

A protocol evaluation support apparatus that supports an evaluation of a protocol in which a process procedure including a plurality of paths that connect a plurality of elements is expressed, the protocol evaluation support apparatus comprising:

• a processing device configured to execute
• creation processing for creating a simultaneous merging symbol that specifies simultaneous merging at a portion in the protocol where a plurality of the elements simultaneously merge into one element, and creating a simultaneous branching symbol that specifies simultaneous branching at a portion in the protocol where one element simultaneously branches to a plurality of the elements,
• development processing for developing the protocol after being subjected to the creation processing for each of the paths included in the process procedure,
• removal processing for removing all of the elements that are duplicated in a process after the simultaneous merging symbol and removing all of the elements that are duplicated in a process before the simultaneous branching symbol for the protocol after being subjected to the development processing, and
• calculation processing for making each of individual evaluation values correspond to each of the remaining elements and calculating an overall evaluation value of the protocol based on the individual evaluation values made to correspond to the remaining elements for the protocol after being subjected to the removal processing.
