According to one embodiment, an existent person count estimation apparatus includes motion sensors and following units. The collection unit generates human sensing information. The instance prediction unit predicts second instances from the first instances by using the transition matrix. The likelihood calculation unit calculates likelihoods of the second instances using the time information items. The instance selection unit selects one or more third instances having likelihoods higher than a threshold. The output unit generates output information including estimate values of existent person counts for the first areas included in the third instances.

There is provided a DR (Demand Response) countermeasure proposal device in which the communication unit receives a power consumption reduction, the rule database stores instrument control rules related to instruments, the rule ranking history database stores information on a ranking of the instrument control rules, the display displays the instrument control rules according to the ranking, the rule ranking changing unit changes the ranking of the instrument control rules in response to an instruction input from the customer, the DR execution unit selects at least one instrument control rule by execution of which the power consumption reduction request is satisfied in descending order of the ranking of the instrument control rules, and executes the at least one instrument control rule to control operation of at least one instruments related thereto.
摘要:
A part fault table indicating the number of days used, a fault flag and a first weight is generated for each of plural parts. A survival curve and a hazard function for each of the plural parts are also generated. Then, convergence is determined by calculating a hazard value using the hazard function for each part in the same group, calculating a second weight by normalization using the hazard value of each part and comparing the first and second weight with each other. Finally, a control operation is performed in such a manner that the convergence determination is terminated by outputting the survival curve or updates the first weight with the second weight, while a new survival curve and a new hazard function are generated from the part fault table using the updated first weight, after which the convergence determination is determined again.
