SIMULATION DEVICE, SIMULATION METHOD, AND MEMORY MEDIUM

Document Type and Number:

WIPO Patent Application WO/2016/031174

Kind Code:

A1

Abstract:

The present invention performs a high-resolution and high-precision simulation over a wide range in consideration of observation data that is non-ideal, discontinuous, or peculiar. A simulation device 100 includes a system model 21, a data selection processing unit 30, a plurality of observation models 31, a post-distribution creating unit 40, a post-distribution unifying unit 50, and a determining unit 51. The system model 21 calculates a time evolution of a state vector. The data selection processing unit 30 selects multiple items of observation data. The observation model 31 converts the state vector from the system model 21 on the basis of the relationship with the observation data. The post-distribution creating unit 40 creates, on the basis of the state vector from the observation model 31 and the selected observation data, a first post-distribution based on all pieces of the observation data or a second post-distribution based on absent observation data. The post-distribution unifying unit 50 unifies the first and second post-distributions. The determining unit 51 determines which of the second post-distribution or the unified post-distribution is to be used.
