A computer system determines an allocation of resources in a task formed of processes. The task includes a transition between processes corresponding to rework. The computer system comprises: at least one predictor configured to calculate predicted values of an inflow amount and an outflow amount of the items of each of the processes forming the task; and a resource allocation determining unit configured to determine an allocation of the resources to each of the processes. The resource allocation determining unit uses the at least one predictor to form a simulator configured to calculate the predicted values of the inflow amount and the outflow amount of the items of each of the processes in any allocation of the resources, in a case of receiving a request including a constraint condition of the resources and an optimization condition; and determines the allocation of the resources to each of the processes.

A system calculates for each frontage space which is held by a plurality of shelves and in which commodities are placed, a recommended capacity value of the commodity based on a predicted shipment volume from demand prediction of the commodity placed in the frontage space. The system determines exchange pairs (frontage space pairs) in each of which exchange of the commodities are performed based on a current capacity value and the recommended capacity value of each frontage space. Each exchange pair satisfies the following: The current capacity of a first frontage space is smaller than the recommended capacity, or the current capacity of a second frontage space is larger than the recommended capacity. The recommended capacity of the second frontage space satisfies the current capacity of the first frontage space. The recommended capacity of the first frontage space satisfies the current capacity of the second frontage space.

An information providing apparatus for collecting data including personal information and distributing the data to a user terminal performs anonymization processing for converting data, which an individual who is an owner of personal information allows to use, into data with which the individual cannot be identified using multiple parameters, thus generating multiple anonymized data protecting the, privacy of the individual. Since each of the anonymized data is anonymized using a different parameter, the amount of information of each of the anonymized data is different. Then, when a request is received from a user terminal, anonymized data that can be provided to the user are identified from among multiple generated anonymized data on the basis of the reliability of the user who uses the user terminal.
