Substrate production simulation method

A substrate production simulation method of simulating production of a product substrate on which mounting of a component supplied from a component supply device is completed using a substrate production line including a mounting line in which multiple component mounters for mounting the component on a substrate are arranged along a conveyance direction of the substrate, the substrate production simulation method comprising:

• (a) a step of obtaining a first result by simulating production of multiple types of the product substrates by the substrate production line on an assumption that provision and collection of the component supply device with respect to the substrate production line are performed without delay;
• (b) a step of obtaining a second result by simulating the production of the multiple types of product substrates by the substrate production line on an assumption that provision and/or collection of the component supply device with respect to the substrate production line is performed by an automated facility and/or a worker;
• and
• (c) a step of outputting a production delay related display in which a production delay of the second result with respect to the first result is displayed in association with the product substrate, and a parameter related display in which a parameter to be a factor of the production delay included in the second result is displayed in association with the product substrate on the same screen.
