Abstract: A risk management device includes: a memory for storing risk weighing data and a threshold risk amount, the risk weighing data including a plurality of scenario data each including a combination of a loss event content, loss occurrence frequency and a loss amount; and a processor. The processor is programmed to calculate post-change risk weighing data obtained by changing only loss occurrence frequency or a loss amount of one specific scenario data of the risk weighing data and transmit to a risk weighing device, and repeatedly executing a process of comparing a risk amount received from the risk weighing device with the threshold risk amount while changing a change width of the loss occurrence frequency or the loss amount, thereby performing calculation of an increase rate of the loss occurrence frequency or the loss amount of the specific scenario data such that a risk amount reaches the threshold risk amount.

Abstract: A storing unit stores loss data each including a loss amount and loss occurrence frequency, and a coefficient table holding a coefficient in association with the loss occurrence frequency, the coefficient being equal to a value of an occurrence number at a lower ? % point (? is a predetermined constant) in a cumulative distribution function of a probability distribution with the loss occurrence frequency as a parameter. A processor is programmed to calculate multiplication values, each of which is calculated for each of the loss data and is a multiplication value of the coefficient held in the coefficient table in association with the loss occurrence frequency included in the loss data and the loss amount included in the loss data.

Abstract: A risk management device includes a memory for storing actual total loss amounts of N periods, and a processor connected to this memory. The processor is programmed to determine whether actual levels showing confidence intervals of actual total loss amounts in a total loss amount distribution calculated by the risk weighing device follow a uniform distribution on an interval [0,1], by a goodness-of-fit test using order statistics for a uniform distribution.

Abstract: A risk management device includes: a memory for storing a plurality of verification units each composed of one or more scenario data each including a predicted value of loss occurrence frequency, a verification range that is a collection of the plurality of verification units, and actual loss occurrence numbers corresponding to the scenario data; and a processor connected to the memory. The processor is programmed to determine by using a goodness-of-fit test on a Poisson distribution whether the total value of the loss occurrence numbers corresponding to the scenario data included in the verification range follows a Poisson distribution that the total value of predicted values of loss occurrence frequency in the scenario data included in the verification range is defined as a mean.
