Abstract: Inputting data necessary for designing an IT system leads a throughput evaluation part to draft a system idea meeting a design standard value for throughput and leads a reliability evaluation part to draft the system idea meeting a design standard value for failure probability. A cost evaluation part evaluates a cost of the system idea, while a cost judgment part judges whether there exists a system idea whose cost evaluated by the cost evaluation part is within an allowable range or not. When the cost judgment part judges that there is no system idea, a reconfiguration part reconfigures the design standard value for throughput, the design standard value for failure probability, and the allowable range of cost in the input data part, and the reconfiguration part carries out calculations repeatedly until there can be drafted a system idea whose cost is within the allowable range.

Abstract: A system for correctly evaluating a price distribution and a risk distribution for a financial product or its derivatives introduces a probability density function generated with a Boltzmann model at a higher accuracy than the Gaussian distribution for a probability density. The system has an initial value setup unit and an evaluation condition setup unit.

A velocity/direction distribution setup unit supplies the probability distributions of the price, price change rate, and the price change direction for the financial product to the Boltzmann model analysis unit.

Abstract: A remote control system includes a commander, a device to be controlled, and a relay unit. The commander transmits a start command and an end command, and a continuation command at intervals of first specific time after transmission of the start command until the end command is transmitted. The relay unit includes a control unit that causes a control signal transmission unit to start transmitting the control signal in response to receipt of the start command and that causes the control signal transmission unit to stop transmitting the control signal in response to receipt of the end command. The control unit causes the control signal transmission unit to stop transmitting the control signal when the next command is not received even after elapse of a second specific time since the command is received, the second specific time being longer than the first specific time.
