Route determination system, route determination method, and route determination program

A route determination method for determining a transport route for an autonomous mobile body to transport an article on from among a plurality of candidates, the route determination method comprising:

• acquiring setting information related to necessity of at least one of cooling retention and heat retention of the article;
• extracting, for each of the plurality of candidates, a low-temperature environment part in which a temperature in a delivery environment of the article along the candidate is estimated to be lower than temperatures of other parts of the candidate when the setting information about the cooling retention is acquired, or a high-temperature environment part in which the temperature is estimated to be higher than temperatures of other parts of the candidate when the setting information about the heat retention is acquired;
• and
• determining the transport route from among the plurality of candidates so that the temperature in the delivery environment of the article becomes low based on a length of the low-temperature environment part when the setting information about the cooling retention is acquired, and determining the transport route from among the plurality of candidates so that the temperature in the delivery environment of the article becomes high based on a length of the high-temperature environment part when the setting information about the heat retention is acquired.

A non-transitory computer readable medium storing a route determination program for determining a transport route for an autonomous mobile body to transport an article on from among a plurality of candidates, the route determination program causing a computer to execute:

• acquiring setting information related to necessity of at least one of cooling retention and heat retention of the article;
• extracting, for each of the plurality of candidates, a low-temperature environment part in which a temperature in a delivery environment of the article along the candidate is estimated to be lower than temperatures of other parts of the candidate when the setting information about the cooling retention is acquired, or a high-temperature environment part in which the temperature is estimated to be higher than temperatures of other parts of the candidate when the setting information about the heat retention is acquired;
• and
• determining the transport route from among the plurality of candidates so that the temperature in the delivery environment of the article becomes low based on a length of the low-temperature environment part when the setting information about the cooling retention is acquired, and determining the transport route from among the plurality of candidates so that the temperature in the delivery environment of the article becomes high based on a length of the high-temperature environment part when the setting information about the heat retention is acquired.
