Latest Patent Applications

1. **PARAMETER ESTIMATION DEVICE AND PARAMETER ESTIMATION METHOD** - This application describes a parameter estimation device that repeatedly executes an estimation process for estimating a parameter using an ensemble Kalman filter based on measured value data multiple times. The device enhances the estimation process by increasing the number of ensemble members and decreasing the magnitude of system noise from previous iterations. It also sets an initial value of the parameter using the estimation result from the previous iteration.

2. **SIMULATION SYSTEM AND COMPUTER-READABLE MEDIUM** - This application involves executing a digital twin simulation. In this simulation, the personal relationship level between two workers is calculated. Based on this relationship level and the work content data scheduled for execution, the system searches for an assignment pattern of workers that meets a reference condition, ensuring work efficiency in a digital space is equal to or greater than a target value.
