Visit-time-determining device

2:

• The visit-time-determining device according to claim 1, wherein the circuitry performs a prediction of whether a resident of a visit destination is at home for each visit destination and time, and determines a visit time for each of the visit destinations on the basis of a result of the prediction.

3:

• The visit-time-determining device according to claim 1, wherein the circuitry selects a visit destination for which the visit time is to be re-determined on the basis of at least one of the number of visit destinations belonging to a clustering cluster and a spatial size of the cluster.

4:

• The visit-time-determining device according to claim 2, wherein the circuitry selects a visit destination for which the visit time is to be re-determined on the basis of at least one of the number of visit destinations belonging to a clustering cluster and a spatial size of the cluster.
