STATE ESTIMATION DEVICE, METHOD, AND PROGRAM

The invention relates to a state estimation device, method, and program. When a future state of a first product (an individual to be estimated) is estimated, a first extrapolated estimated value (f) is calculated from past-side data (data (2)) among data relating to the first product. And calculates a second extrapolated estimated value F on the basis of data (data 1) relating to a second product different from the first product (another individual of the same type as the individual to be estimated). A synthesis ratio a between the first extrapolated estimation value f and the second extrapolated estimation value F is determined from current-side data (data 3) among the data relating to the first product, and an estimation value obtained by synthesizing the first extrapolated estimation value and the second extrapolated estimation value on the basis of the determined synthesis ratio a is calculated. 本公开涉及状态估计装置、方法以及程序。在对第一产品(估计对象个体)的将来的状态进行估计时，根据与第一产品相关的数据中的过去侧的数据(数据2)来计算第一外推估计值f，并且根据与不同于第一产品的第二产品(估计对象个体的同类型其
