Cleaning route determination system and method for determining cleaning route

A cleaning route determination system comprising:

• a calculation condition inputter configured to receive a calculation condition including information regarding an inside of a facility;
• an analyzer configured to perform an analysis of a behavior of airflow and particles inside the facility based on the calculation condition and an airflow speed induced by human movement;
• a map generator configured to generate a dust accumulation map based on the analysis by the analyzer, the dust accumulation map indicating one or more dust accumulation areas inside the facility and one or more dust amounts corresponding to the one or more dust accumulation areas;
• and
• a route calculator configured to determine a first route from second routes based on the dust accumulation map,
• wherein each of the second routes is a route for a cleaner to pass through at least one of the one or more dust accumulation areas within a certain period of time, and
• wherein a total amount indicating a sum of dust amounts corresponding to dust accumulation areas of the first route is largest among total amounts corresponding to the second routes, each of the total amounts indicating a sum of dust amounts corresponding to dust accumulation areas included in each of the second routes.
