Safety analysis system for wiring

A safety analysis method for wiring in a wiring structure in which each of a plurality of electric wires belonging to a wire harness is connected to a pair of connectors located at terminals via a relay element, the safety analysis method comprising:

• storing:
• electric wire-terminal connector correlation information in which each of the plurality of electric wires and the pair of connectors are correlated with each other, terminal connector-function correlation information in which the pair of connectors located at the terminals and a function of a device to which the connectors are connected are correlated with each other, and
• function determination information including a combination of a plurality of functions that are not allowed to be lost at the same time;
• matching the electric wire-terminal connector correlation information and the terminal connector-function correlation information when the wire harness is identified;
• generating electric wire-function correlation information in which each of the plurality of electric wires and the function of the device are correlated with each other;
• determining whether or not the combination of the plurality of functions included in the function determination information exists in the generated electric wire-function correlation information;
• and
• evaluating that the wire harness is safe when the combination does not exist.
