Abstract: An electric vehicle management apparatus (10) includes a charging plan acquisition unit (110), an operation plan acquisition unit (120), and an output unit (150). The charging plan acquisition unit (110) acquires vehicle identification information of at least one electric vehicle incorporated with a battery, and charging plan information indicating a charging schedule period of the electric vehicle associated with the vehicle identification information, in association with each other. The operation plan acquisition unit (120) acquires the vehicle identification information of a target vehicle being the electric vehicle for which operation timing is determined, and the operation timing of the target vehicle, in association with each other. The output unit (150) outputs first vehicle information indicating the target vehicle, when the charging plan information of the target vehicle is absent, or when it is indicated that charging is not completed before the operation timing in the charging plan information.

Abstract: An input unit 81 receives inputs of pre-change performance data acquired by a device before a change and post-change performance data acquired by the device after having undergone the change, through control using a first cost function. An update unit 82 generates a second cost function obtained by updating the first cost function in such a way as to reduce a difference between the pre-change performance data and the post-change performance data. In the process, the update unit 82 generates the second cost function obtained by updating the first cost function by estimating an error that occurs in an output value of the device included in the first cost function before and after the change to the device.

Abstract: The present invention provides a processing apparatus (10) including a prediction information acquisition unit (11) that acquires remaining-fuel-amount prediction information indicating a change in a predicted value of a remaining amount of fuel in a vehicle while traveling based on a transport plan is performed and being produced based on a prediction model, an actual measurement information acquisition unit (12) that acquires remaining-fuel-amount actual measurement information indicating a change in an actual measurement value of a remaining amount of fuel in the vehicle while traveling based on the transport plan is performed, and a determination unit (13) that determines, based on the remaining-fuel-amount prediction information and the remaining-fuel-amount actual measurement information, whether correction of the prediction model is necessary.

Abstract: A transportation plan acquisition unit (11) acquires a transportation plan including a transportation destination, an order of transportation, and a weight of a cargo. A terminal departure time state of charge (SOC) acquisition unit (12) acquires an SOC of a vehicle at a time of departure from a terminal. An SOC change prediction unit (13) determines, based on the transportation plan, a load during transportation changing in response to loading and unloading of the cargo during transportation, and predicts, based on the determined load, a change of an SOC of the vehicle during transportation when transportation following the transportation plan is performed. A determination unit (14) determines whether a point where an SOC drops below a reference value exists in a change of an SOC of the vehicle during transportation. A determination result output unit (15) outputs a result of the determination.

Abstract: The input means 81 accepts input of observation data observed along with an operation of equipment and input of a cost function whose explanatory variable is a factor of action intended by equipment operator. The learning means 82 generates the cost function by inverse reinforcement learning using the observation data. The distribution map generation means 83 extracts weight of the explanatory variable of the generated cost function as a feature representing an intention of the operator, and generates a distribution map in which information on the cost function is placed at corresponding positions in a multidimensional space with the explanatory variables as dimensional axes according to the extracted feature.
