Abstract: An area evaluation unit (51) acquires for each area of a plurality of areas, a predictive value of each area which is predicted to be measured when a device operates in a space that includes the plurality of areas. A building evaluation unit (52) acquires an overall predictive value which is a predictive value of the entire space calculated using a plurality of predictive values of the plurality of areas. Further, the area evaluation unit (51) evaluates the predictive value of each area, using a partial evaluation criterion which is an evaluation criterion applied to each area. Further, the building evaluation unit (52) evaluates the overall predictive value, using an overall evaluation criterion which is an evaluation criterion applied to the entire space.

Abstract: A number-of-allowable-users calculation unit (212) calculates, as the number of allowable users of a room, the number of persons with which a distance equal to or greater than a limit distance can be secured in the room, based on limit distance data indicating the limit distance defined as a distance to be kept between persons and room data indicating information on the room to be used by one or more persons.

Abstract: A collection unit (111) collects a plurality of sensor values at a plurality of measurement points from a plurality of sensors provided to the plurality of measurement points, and per measurement point, accumulates environmental information data including a sensor value, in an accumulation unit (180). An interpolation unit (112) finds a sensor value at a virtual point based on one sensor value or more obtained by one sensor or more. A management unit (113) accumulates environmental information data including the sensor value at the virtual point, in the accumulation unit.

Abstract: An installing environment estimation device (10) includes: a data acquisition unit (11) to acquire data collected by an apparatus such as a sensor and camera of a mobile terminal carried by a maintenance personnel member to a building site, the data concerning an installation place of equipment which is installed at the building site; a feature quantity extraction unit (12) to extract a feature quantity of the acquired data; and an installing environment estimation unit (13) to estimate an installing environment of the equipment based on a classification model, by collating the feature quantity of the data with the classification model. The classification model is set for an item of the feature quantity of an individual apparatus. A range that the feature quantity which expresses an installing environment of equipment can have is set in the classification model.

Abstract: In the present invention, unauthorized access from outside a facility to a device disposed inside the facility is detected by effectively using the output from a mirror port of a network switch. A gateway device has: a monitored data acquisition unit for saving in a monitored data storage unit, as monitored data, packet data that is outputted from a mirror port of a switch, the packet data being outputted from a device being monitored; an unauthorized access detection unit for detecting unauthorized access by determining whether the monitored data is abnormal on the basis of a comparison between the monitored data and assessment rules; and an unauthorized access notification unit for notifying a server of a monitoring center, which is connected to an external network via an external communication unit, that unauthorized access has been detected.
