    Abstract: [Problem] When a resource reserved in a resource sharing system become unavailable, the reservation is efficiently reset. [Solution] A resource sharing system 10 shares resources 30 with a plurality of users 20 (user terminals). A resource reservation management device 42 includes: a reservation setting unit 402 that accepts a reservation request for the resource 30 from the user 20, and sets a reservation on a predetermined resource 30 in the resource sharing system 10; and a reservation changing unit 404 that resets the reservation to another resource 30 in the resource sharing system 10 in case the predetermined reserved resource 30 becomes unavailable. if the other resource 30 has insufficient resource capacity, the reservation changing unit 404 resets the reservation to the other resource 30 based on a reservation changing policy defining which reservation is preferentially reset out of the reservation to be reset.
